EXECUTIVE SUMMARY

1. Objectives

The main objectives of the Survey are to:

1) Collect and organize the latest information and data on electricity supply system,

including transmission and distribution losses in Sri Lanka;

2) Confirm the system efficiency program prepared by Ceylon Electricity Board (CEB) and

shortlist CEB’s requested projects, which will contribute to the efficiency of the

electricity supply system, to be applied for Japan’s Loan Aid; and

3) Prepare the project summary including conceptual design, approximate cost estimate,

and simplified economic evaluation of the projects requested.

2. Issues on Transmission and Distribution Network

Through the discussions with CEB and site survey conducted, the Survey Team found the

following issues on the existing transmission and distribution network;

1) Issues on the transmission network

i) Rapidly increasing power demand in Colombo City

ii) Transmission lines with old design concept

iii) System reliability

iv) Shortage of reactive power

v) Voltage drop at the end of the network, etc.

2) Issues on the distribution network

i) Overloading in primary substations

ii) Voltage drop

iii) Lack of distribution automation system (DAS)

iv) Lack of energy meters and data transmission

v) Increase of transformer loss by inadequate transformer capacity

vi) Distribution losses caused by long low voltage (LV) lines

vii) Theft of electric power

viii) Resistive losses at connection points on LV lines

ix) Aged and deteriorated facilities

x) Salt contamination along seaside

xi) Tariff for street lighting, etc.

CEB has prepared project proposals as countermeasures against the above issues and

submitted them to the Survey Team in order to request support for Japan’s Yen Loan.

3. Candidate Projects

The Survey Team reviewed the proposed project costs, and estimated the amount of loss

reduction and economic internal rate of return (EIRR) of each project as shown in Table 1.

(Prepared by the Survey Team)

As shown in the above table, the total project cost was estimated at LKR 59,588 million (JPY

35,277 million equivalent), and total loss reduction amount was estimated at 130,163

MWh/year.

4. Environmental and Social Considerations

All candidate projects will have environmental impacts such as air pollution, noise and

vibration, waste water discharge, and soil contamination. Unsanitary conditions at the

workforce camp without proper treatment facility will expose the laborers to sicknesses.

Moreover, accidents outside the sites could occur any time since the project may affect the

traffic system as the traffic volume is anticipated to be heavier. The degrees of such

impacts, however, are only small scale and temporary during construction period.

Based on the legislations of Sri Lanka and JICA Guidelines for Environmental and Social

Considerations, it can be concluded that the following mitigation measures should be taken

and be monitored during construction period:

Air quality: The amount of SPM has to be monitored periodically, and the construction

method should be altered in case it exceeds the environmental standard.

Water quality: The amount of SS and oil has to be monitored periodically, and the

construction method should be altered in case its impact exceeds the environmental

standard.

Waste: Although waste generated at the construction site and disposal of construction debris

will be collected regularly by the local authority, project staff has to physically observe the

waste disposal condition, and improve the method of disposal in case it is done

inappropriately.

Soil: Project staff has to observe the soil condition, and send the sample soil to laboratories

in case there is any contamination.

Noise and vibration: Time management and appropriate work shifts for particular tasks can

reduce continuous exposure to such noise and vibration.

Working condition: A tangible safety consideration should be given to laborers, such as

wearing helmets, gloves, shoes, and working clothes in order to mitigate the risks of

accidents. Appropriate working hours such as three-shift a day, two days off a week, etc.,

can keep laborers’ health condition well. Treatment systems such as septic tank can be

installed in order to keep a safe and hygienic working condition.

Traffic: In order not to disturb the traffic system in urban areas, in particular where projects

are located, construction work in and around cities/towns can be shifted to night time or

weekends. Advance information disclosure on the construction schedule will also

contribute to minimizing traffic impacts.

Accidents: Project construction during night and weekend shifts can help decrease

disturbance to the traffic in urban areas. Information regarding the construction schedule

should be disclosed in advance so that the locals will be aware and mitigate the risks of

traffic accidents. Installation of ‘keep out’ sign boards at locations where construction works

are ongoing can keep passers-by away from accidents.

5. Economic Evaluation

The results of the economic analysis in terms of the benefit cost (B/C) ratio and EIRR of

each candidate project under the base case and sensitivity analysis case (under the

condition of a 30% increase of the total project cost) are shown in Table 2.

Table 2 B/C ratio and EIRR of the Candidate Projects

Name of Project B/C ratio EIRR

base sensitivity base sensitivity

#1 Colombo City Transmission Development Project 1.59 1.22 18.63% 14.68%

#2 Construction of Kappalthurai 132/33 kV GS with related TL 1.62 1.25 16.59% 13.37%

#3 Construction of Grid Substations surrounding Colombo City 1.93 1.48 17.94% 14.95%

#4 Construction of Veyangoda - Kirindiwela - Padukka 220 kV TL 1.51 1.16 16.11% 13.59%

#5 Distribution Project for North Western Province of Region 1 1.13 0.87 12.92% 8.87%

#6 Distribution Project for Western Province North of Region 2 1.42 1.09 17.19% 12.37%

#7 Distribution Project for Western Province South-2 of Region 3 1.48 1.14 18.09% 13.09%

#8 Distribution Project for Western Province South-1 of Region 4 0.93 0.71 9.85% 6.28%


Table 2 shows that the B/C ratio ranges from 0.93 to 1.93 for the base case and 0.71 to 1.48

under the sensitivity analysis case. Thus, it can be said that the candidate projects will

bring benefits, with the exception of Project #8, since its B/C ratio is below 1.0 for both cases.

As for the EIRR, it ranges from 9.85% to 18.63% for the base case and 6.28% to 14.95% for

the sensitivity analysis case. With the exception of Project #5 and Project #8, under the

sensitivity analysis case, the results indicate that the candidate projects shall deliver

economic benefits. Thus, from an economic perspective, since most projects yield

satisfactory B/C ratio and EIRR under both cases, the candidate projects may proceed.

CHAPTER 1 INTRODUCTION

1.1 Background and Objectives

The Japan International Cooperation Agency (JICA) has been continuously supporting the

power sector of the Democratic Socialist Republic of Sri Lanka, for the efficiency of

transmission and distribution facilities that will result to the stabilization of electric power

supply, leading to the economic development of Sri Lanka. Especially, JICA has been

assisting in the transmission and distribution lines reinforcement projects around the suburbs

of Colombo City and in the rural areas since the end of the 1990s.

Following a 7% annual average economic growth rate of Sri Lanka, large-scale generating

plants are needed to meet the rapidly increasing electricity demand. In 2011, the recorded

electricity demand reached 2,163 MW and according to the 2020 forecast, around 4,051 MW

will be required. However, the development of transmission and distribution facilities has

not been expanded and resulted to 11.7% of transmission and distribution losses in 2011.

Such weaknesses of the network shall be improved through the reinforcement of

transmission capacity and efficient utilization of energy.

According to the “Mahinda Chintana (Mahinda Vision)”, the Government of Sri Lanka will

take the necessary steps to provide all households with continuous electricity supply by the

end of 2012. To achieve this, the government will focus on several strategies, such as

sustainable generation development, improved access to electricity supply services, efficient

utilization of electric energy, and improved electricity tariff system. Among these strategies,

efficient utilization of electric energy is recognized as the key strategy. Concretely, such

strategies are the utilization of renewable energy, reduction of transmission and distribution

losses, promotion of energy-saving equipment for electricity uses, etc. With regards to the

transmission and distribution losses, the Mahinda Chintana states that “in order to minimise

the transmission losses and also to introduce modern technologies, steps have already been

taken to modernise and start new construction of transmission networks and substations

covering all geographical areas of the country.” To achieve this, the Ceylon Electricity

Board (CEB) has prepared the “Long-term Transmission Development Plan 2011-2020”

which is a result of several studies, including power flow calculations based on the long-term

power demand forecast and generation development plan.

Under such circumstances, once again, JICA has decided to conduct a data collection

survey on electricity supply system efficiency in Sri Lanka (hereinafter referred to as ‘the

Survey’) this year. This is intended to collect and organize necessary information for

Data Collection Survey on Electricity Supply System Efficiency in Sri Lanka

1 - 2

realizing improved efficiency in the electricity supply system which includes the reduction of

transmission and distribution losses, and for justifying the requirements for Japan’s Loan Aid

assistance for the loss reduction program, considering the application of Japan’s system

efficiency techniques. JICA has employed Japanese consulting firms, namely, Nippon Koei

Co., Ltd. (NK) in association with Tokyo Electric Power Services Co., Ltd. (TEPSCO) and

Sojitz Research Institute, Ltd. (SRI) (herein after referred to as ‘the Survey Team’) to conduct

the Survey.

The main objectives of the Survey are as follows:

1) To collect and organize the latest information and data on electricity supply system,

including transmission and distribution losses in Sri Lanka;

2) To confirm the system efficiency program prepared by CEB and shortlist CEB’s

requested projects, which will contribute to the efficiency of the electricity supply system,

to be applied for Japan’s Loan Aid; and

3) To prepare the project summary including conceptual design, approximate cost

estimate, and simplified economic evaluation of the projects requested.

1.2 Scope of the Survey

The scope of the Survey is as follows:

1) Confirm CEB’s policies and countermeasures to be taken for system efficiency;

2) Confirm the current situation of transmission and distribution network in Sri Lanka;

3) Confirm development assistance of the power sector by other international donors;

4) Prepare the shortlist of candidate projects for system efficiency to be applied for

Japan’s Loan Aid;

5) Conduct site visit surveys of candidate project sites;

6) Conduct power flow calculations to confirm the efficiency of the candidate projects;

7) Review environmental and social conditions of the candidate projects based on JICA’s

environmental guideline;

8) Consider the possibility of applying Japanese system efficiency technology to the

candidate projects;

9) Prepare project summaries including conceptual design, approximate cost estimates,

environmental and social considerations, simplified project evaluation, procurement and

implementation plan, operation and maintenance (O&M) plan, etc.;

10) Prepare the reports listed in Section 1.3; and

11) Carry out explanations to and discussions with JICA and Sri Lankan officials.

8) Promotion of energy efficiency; and

9) Development of indigenous renewable energy resources.

The Sri Lanka Electricity Act No. 20 of 2009 was enacted by the parliament with the sole

objective of implementing the national policy for the power sector. The policy has been

formulated with a view of enabling Sri Lanka to meet the expected increasing demand for

electricity. The act cites provisions to regulate the generation, transmission, distribution,

supply and use of electricity in Sri Lanka. In particular, the act addresses the following

concerns/issues:

1) Provision of 24 hours uninterrupted electricity for all at all times;

2) Adoption of a transparent tariff policy that is acceptable to the government, consumers

and utilities to ensure reasonable cost recovery;

3) Implementation of lower cost generating plants and the adoption of open competitive

transparent bidding processes for the procurement of electricity by utilities, the

establishment of a transparent power plant dispatch programme in 2009 and the

Atomic Energy Authority (AEA);

Lanka Electricity Company (Pvt) Limited. (LECO);

Lanka Transformer (Pvt) Ltd. (LTL);

Lanka Coal Company (Pvt) Ltd.(LCC); and

Polipto Lanka (Pvt) Ltd. (PL)

(2) Public Utilities Commission of Sri Lanka

The Public Utilities Commission of Sri Lanka (PUCSL) was established through Act No 35 of

2002 as a multi-sector regulator to manage certain physical infrastructure industries in the

country. Initially the PUCSL Act addressed regulations for electricity and water service

industries. Later in March 2006, the petroleum industry was added to the list of industries to

be regulated by the PUCSL.

With the enactment of the Sri Lanka Electricity Act No. 20 of 2009, PUCSL became the

economic, safety and technical regulator of the electricity industry. With a view of ensuring

adequate investment, greater availability, efficient supply, and improved quality of services in

the electricity industry, the PUCSL regulates the generation, transmission, distribution,

supply and use of electricity in Sri Lanka.

Being the regulator for the electricity industry and water services and downstream petroleum

industries, the PUCSL Act identifies broad functions listed out as follows;

1) Exercise, perform and discharge the powers, functions and duties assigned to the

PUCSL by the act;

2) Consult, to the extent where the PUCSL considers appropriately, any person or group

who or which may be affected, or likely to be affected by the decisions of the PUCSL;

3) Advice the government on all matters concerning any industry falling within the purview

of the PUCSL;

4) Collect, record, and disseminate, information concerning any public utilities industries;

5) Prepare within six months a regulatory manual containing a code of good practice

which governs the functions of the PUCSL and revise when necessary;


2 - 3

6) Exercise licensing, regulatory and inspection functions within respect to all matters

provided by any industry act;

7) Enforce the provisions of licenses, contracts and other instruments issued under the

authority of any industry act;

8) Regulate tariffs and other charges levied by regulated entities when necessary;

9) Mediate disputes arising in any public utilities industry;

10) Set and enforce technical and other standards relating to the safety, quality, continuity

and reliability of the public utilities industries; and

11) Undertake such other incidental or ancillary activities for the effective discharge of any

of its functions.

(3) Electric Power Utilities

CEB and LECO are the only two electric power utilities in the power sector. CEB was

established in terms of the Act of Parliament No.17 of 1969 as a state-owned, vertically

integrated utility. CEB is responsible for power generation, transmission, and distribution.

It raised 89.2% of electricity sales in Sri Lanka and served 4.7 million customers in 2011.

LECO was formed in 1983 as a distribution company under the Sri Lankan Companies Act.

It purchases electric power from CEB and distributed 1,216 GWh of energy to approximately

490,000 consumers in 2011 in the western and coastal belt townships between Negombo

and Galle.

The power sector of Sri Lanka is struggling to meet its growing electricity demand.

Economically viable hydropower potentials have already been developed, however power

crises in the past drew attention to the importance of timely implementation of new

generating plants to meet the growing demand. The power crises have been caused by

vulnerability to rainfall. Moreover, limitations of hydropower plants during severe drought

fluctuations forced load shedding to limit the daily electricity demand. Since 1996, the

Government of Sri Lanka (GoSL) has allowed independent power producers (IPPs) to build,

own, and operate thermal power plants to encourage private sector participation in meeting

the power supply requirements. The share of electric energy from hydropower plants in the

power generation ratio declined from 99.7% in 1986 to 40.1% in 2011. At present, Sri

Lanka relies heavily on imported fuel for its electric energy requirements.

The total installed power generation capacity in 2011 amounted to 3,141 MW, which includes

the capacity of IPPs of 1,082 MW. Of the capacity feeding the main grid, 44.6% was

sourced from hydropower while the balance from thermal, except for 50 MW of new

renewable energy such as wind, solar, dendro, and biomass. The peak demand in 2011

was 2,163 MW. Of the total 10,023 GWh electricity sale of CEB in 2011, domestic

(households) consumers had the largest share at 33.7%, followed by the industrial sector


2 - 4

(31.2%), general and commercial consumers (19.2%), bulk supply by CEB to LECO (12.6%),

street lighting (1.1%), and religious sector (0.5%).

2.2 Power Sector Policies

'Mahinda Chintana (Mahinda Vision)’ was formulated by the GoSL in 2006 to set out Sri

Lanka's development vision for the 10-year period 2006-2016. Based on an extensive

consultation process, the vision sets out a broad macroeconomic framework. It sets out 10-

year policy frameworks for various sectors of the economy, including broad vision, situational

analysis and strategy. It aims for an ambitious acceleration of growth through a scaling up

of investment and increasing productivity.

As for the power sector policy, Mahinda Chintana focuses on infrastructure development to

accelerate the country’s economic growth, narrow down regional disparities, and envision

sustainable development of energy resources. It also focuses on enabling electricity

access to the entire population, and reliable service delivery at a competitive price through

commercially viable institutions subjected to independent regulation. The framework is

based on the National Energy Policy and Strategies formulated by the MOPE.

The MOPE updated this development policy framework in 2010. This provides a

comprehensive sector development road map, including a long-term investment program

and policy and reform measures. In particular, the strategies updated in 2010 aim to:

1) Increase supply capacity of the system to 3,470 MW by 2012 and 6,367 MW by 2020

and reduce generation cost by adding an aggregate base load capacity of about 2,000

MW from three coal-fired plants;

2) Increase share in grid energy supply from nonconventional renewable energy sources

from 4.1% in 2007 to 8.5% by 2012, 10% by 2016, and 20% by 2020;

3) Increase the percentage of households connected to the grid from 88% in 2010 to

100% by 2012;

4) Reduce the total technical and commercial losses of the transmission and distribution

network from 14.6% in 2009 to 14.0% by 2012, 13% by 2016 and 12.0% by 2020; and

5) Achieve energy savings of 4.3% in 2012, 6.4% in 2016, and 8.7% in 2020 from a

potential consumption level through energy conservation.

The government’s main goals are to improve the quantity, quality, and cost of service delivery,

and to increase electricity connections in rural areas.

The National Energy Policy and Strategies also states that “power generation and network

losses will be brought down to the lowest possible levels and capacity will be improved

through necessary generation, transmission, and distribution investments and efficient

management of the supply systems”. To achieve this, CEB has been continuously exerting

utmost efforts in various ways for the reduction of transmission and distribution losses, which


2 - 6

will be discussed in the following sections.

2.3 Current Situation and Issues

2.3.1 Transmission and Distribution Losses

Total system energy losses, including generation, transmission and distribution losses in

CEB’s network, are gradually being reduced over the past years as shown in Figure 2.3-1.

Losses (%)

(Source: CEB 2009 Annual Report and Statistical Digest 2011)

Figure 2.3-1 System Energy Losses

The system energy loss in 2011 was 13.00%, of which transmission and distribution loss was

11.72% and generation loss was 1.28%. In comparison to transmission and distribution

loss being 12.97% in 2010, a 1.25% reduction was achieved in 2011 as a result of CEB’s

reduction efforts. However, transmission and distribution losses, especially the latter, were

still at a high level and countermeasures for loss reduction are to be taken continuously.

2.3.2 Transmission Network

(1) Current Situation

The present transmission system in Sri Lanka consists of a nationwide network of 220 kV

and 132 kV transmission lines (TLs) which feed several 220/33 kV and 132/33 kV grid

substations (GSs). Table 2.3-1 shows the summary of the existing TLs and GSs. Figure

2.3-2 shows the existing transmission network of Sri Lanka.

2 - 8

As shown in Figure 2.3-2, there are three major 220 kV transmission corridors transmitting

bulk power generated from large-scale generating plants to major load centers as follows:

1) From hydropower plants in Mahaweli Complex in the Central Province to Biyagama GS

in the Western Province

2) From Kotmale HPP in the Central Province to New Anuradhapura GS in the North

Central Province

3) From Norochcholai Coal Thermal Power Plant in the North Western Province to

Kotugoda GS in the Western Province

The 132 kV transmission lines are constructed nationwide. Other medium- and small-scale

power plants and grid substations are connected through these lines. Most of the 220 kV

and 132 kV transmission lines are overhead lines, except for the 132 kV underground cable

lines in Colombo City with gas-insulated switchgear (GIS).

(2) Issues on the Transmission Network

As a result of the review and discussions about the system analysis conducted by the CEB

Transmission Planning, the Survey Team found the following issues on the existing

transmission network.

1) Power supply to Colombo City

The electricity demand of Colombo City is rapidly increasing much faster than expected.

This is due to emerging investments and developments such as hotels, commercial

complexes, and port expansions after the end of the civil war in May 2009. Table 2.3-

2 shows CEB’s demand forecast for Colombo City for the period from 2012 to 2032.

Table 2.3-2 Colombo City Demand Forecast (unit: MVA)

Kelanitissa 23.7 28.3 60.2 72.0 Kolonnawa 68.2 55.5 62.7 67.4

Total 318.1 439.7 675.2 736.6


The existing transmission network in Colombo City mainly consists of 132 kV

underground cables with several 132/11 kV GSs such as Colombo-A, Colombo-C,


2 - 9

Colombo-E, Colombo-F and Colombo-I, and 132/33 kV Kolonnawa and Kelanitissa

GSs. In addition to the above, CEB plans to construct new GSs (as shown in Table

2.3-2) and install additional main transformers in the existing GSs to meet the rapidly

increasing electricity demand with a new 132 kV underground cable network.

However, old and small-sized 132 kV oil filled (OF) cables of the following sections exist

in the Colombo City transmission network;

1) Kelanitissa – Colombo-F, OF 500 mm2, 4.9 km

2) Colombo-F – Colombo-E, OF 350 mm2, 2.7 km

3) Colombo-E – Kolonnawa, OF 500 mm2, 5.4 km

The above cables sometimes leak insulation

oil (as shown in the right photograph) which

may cause serious accidents. In addition,

small-sized cables produce transmission

losses. To avoid accidents and transmission

losses, old cables shall be replaced with more

reliable and large-sized cables.

2) Old design concept

There are many sections of 132 kV transmission lines, which were designed using old

design concepts in the existing transmission network as shown in Table 2.3-3.

Reinforced (ACSR) Lynx (183.4 mm2), Oriole (170.5 mm2), and Tiger (131.1 mm2) with

54°C maximum operation temperature, even though CEB now applies ACSR Zebra

(428.9 mm2) as the standard conductor size for new transmission lines with 75°C

maximum operation temperature.

Some of the above sections, such as Item 4 “Kolonnawa – Athurugiriya – Thulhiriya (T)

– Polpitiya”, Item 7 “Kolonnawa – Kosgama (T) – Sithawaka (T) – Polpitiya”, and Item

12 “Polpitiya – Kiribathkumbra – Ukuwela – Habarana”, are important 132 kV

transmission lines, which carry bulk power flow. However, the limitation of the current

carrying capacity remains a serious obstacle for system operation due to the maximum

operation temperature rations on the power flow. In addition, small conductors

produce transmission losses.

3) System Reliability

The 220 kV Kotmale–Biyagama transmission line is one of the most important lines to

carry bulk power generated from hydropower stations in Mahaweli Complex in the

Central Province to major load centers in Colombo. However, since the Kotmale–

Biyagama line passes through a relatively frequent lightning area, lightning sometimes

strikes the line and causes severe faults such as nationwide blackouts.

To avoid such huge blackout and still have a reliable system, augmentation of the

transmission network, such as construction of diversion transmission lines, is needed.

4) Shortage of reactive power

Electricity demand in Colombo has been rapidly increasing since the end of the civil war.

Reactive power supply cannot meet the system requirements to keep the system

voltage within an appropriate level. To meet the reactive power demand in Colombo,

diesel generators in Sapgaskanda are operated only for the reactive power supply.

This is an emergency measure but a costly alternative. Reactive power compensation

equipment such as static capacitors shall be urgently installed in the existing grid

substations in and around Colombo. This countermeasure also contributes to

transmission loss reduction.

5) Voltage drop

CEB defines the permitted voltage deviation at 132 kV busbars as ±10% in the system

planning criteria. However, voltage drops exceeding the permissible range are

sometimes recorded at substations which are located in rural areas as well as at the

end of the transmission network such as Galle, Valachchenai, and Ampara GSs.

These drops are due to the long distance and small conductor transmission lines.

Voltage drops also increase transmission losses.

To improve such situation, countermeasures such as the construction of a new GS,


2 - 11

reconstruction and augmentation of transmission line, together with the installation of

static capacitors are to be taken.

2.3.3 Distribution Network

(1) General

Recently, remarkable overloading on the distribution facilities of CEB’s network is observed,

especially on the medium voltage (MV) lines from 132 kV GSs to 33 kV primary substations

(PS). This causes distribution losses.

The CEB’s Statistical Digest 2011 shows that the household electrification ratio to be 91.0%

in 2011. Although the electrification ratio in urban areas is generally high, it is very low in

rural areas, especially in the Northern Province. Since electricity demand density of

consumers is very thin in the rural area, distribution lines become very long, causing large

resistive losses on the distribution lines. More than 10% of the voltage drops have been

observed in rural areas. Some components of the distribution system are old which may

cause failures due to poor quality of equipment. In addition, it is necessary to establish an

underground cable system in urban area surrounding Colombo City because of the difficulty

to reinforce the overhead distribution lines.

The distribution system does not provide a sufficient energy metering facilities to measure

the coming and sending of electric power energy. At this moment, there is no energy

metering provided even at the distribution transformers. Thus, it is essential to provide

energy metering to accurately measure energy losses.

In 2012, Colombo City has completed the installation and commissioning of the System

Control and Data Acquisition (SCADA) System under the Colombo City Electricity

Distribution Development (CCEDD) Project funded by JICA. It can control the switchgear

up to 11 kV PSS from the Colombo City Control Center (CCCC), but other regions/areas do

not have the SCADA system like Colombo City. CEB has been developing the SCADA

system and some of these are already under operation at this moment. CEB has

developed several simplified SCADA systems, one of which is the simplified distribution

automation system (DAS) named ‘Micro SCADA’ in the North Western Province in Region 2.

This can operate and monitor switchgear in the network using communication links thru

General Packet Radio Service (GPRS) on public mobile telephone network. However, it is

not a real time control and monitoring of the system. A similar type of simplified SCADA

system is provided in the Central Province. However CEB has recently developed a new

SCADA system in Kandy, which can monitor the system in real time. In other areas, the

switchgear in the network are still manually operated by an electrician with telephone

communication, but not by remote control.


2 - 12

In the Medium Voltage (MV) Distribution Development Study 2010 – 2019 (MV Development

Study) prepared by each distribution region or any other information from the CEB, a

proposal/statement regarding a ‘Smart Grid System’ has not yet been proposed. However,

CEB has the target to proceed with the electrification and rectification of several problems

such as overloading and voltage drop, and has started to provide automatic reading of

energy meter at retail distribution transformers, which will herald the Smart Grid System in

Sri Lanka. It now seems possible to apply the technique of ‘Smart Meter’ to the remote

monitoring of energy meters, which was proposed by the CEB in a letter to the MOPE.

Based on the above information collected during the site survey, the current status of CEB’s

distribution system was evaluated/analyzed and reported as follows.

(2) Current Status of CEB’s Distribution System

1) Boundary of transmission and distribution

The boundary of responsibility between the transmission branch and distribution

branches is the MV gantries of GS. The distribution branches are responsible for the

allocation of facilities from the gantries to consumers. The proposals issued by the

distribution branches cover MV distribution lines (33 kV and 11 kV), PS, distribution

substations and low voltage (LV) lines, but do not include facilities such as capacitor

banks or voltage controllers in GS. When the distribution branches need to provide

such facilities to solve problems on distribution system, the transmission branch will

propose the provision of any necessary equipment.

2) Growth of electricity power demand

The growth of peak demand of each region reported in the MV Development Study is

shown in Table 2.3-4.

Table 2.3-4 Peak Power Demand in Distribution System (unit: MW)

Regions 2011 2012 2013 2014 2015 2016 2017 2018 2019

(Source: CEB MV Development Study)

Note: Total is summation of peak demand in each Region, actual peak demand of CEB overall shall be slightly different because peak

time is different in each Region/Area.

As shown in the table, total peak demand is increasing between 5% to 9% every year in

each region and overall CEB. Also, the growth of power energy demand in satellite

town surrounding Colombo City is very remarkable.


2 - 13

3) Electrification

According to the instruction from the GoSL, CEB intends to increase the electrification

ratio to 100%. However, the electrification ratio in rural areas is lower than that of

urban areas as shown in Table 2.3-5 below.

In rural areas, the electrification level in the Southern Provinces is larger than in the

Northern Provinces. It is striking that the electrification level in the Northern Province

is only 42%, as some islands in the province are neither connected to a transmission

network nor an independent generating system such as diesel generators. Moreover,

they are not synchronized with the main transmission network of CEB.

4) Current status of distribution lines

CEB’s distribution system uses two kinds of ACSR conductors. One is ACSR Lynx

(37/2.79 mm) used for 33 kV trunk lines named the backbone lines and the other is

ACSR Raccoon (7/4.09 mm) used for 33/11 kV branch lines, named the pole lines. As

far as the specifications of the conductors used for distribution lines, no problem or

inadequacy were seen, despite the fact that long distribution distance may have caused

most of the distribution losses.

Table 2.3-6 shows the network components of CEB’s distribution system.

As shown in the above table, the

length of the distribution line is quite

long compared with the total lengths

of distribution lines and the quantity

of distribution substations. Actually,

the length to the most distant

consumer is 1.8 km and the total

lengths of LV lines connected to one

distribution substation is 8 km on the

average and 15 km at maximum. In addition, substandard connections of wires were

observed during site inspection, which may have caused the resistive losses at

connection points. As shown in the above photograph, the winding connection and

connector connection are on a single pole. This may cause the connection to become

loose because of the mechanical characteristic of aluminum which can be deformed by

continuous stress in a long duration.

All distribution lines are underground cables in Colombo City, using 11 kV cables

instead of 33 kV cables due to cost difference. Although losses on the 11 kV

distribution lines in Colombo City are not so large, their lengths are very short. In the

CCEDD project, the existing old 33 kV underground cables have been replaced with

132 kV cables.

5) Distribution automation system (DAS)

The SCADA system is provided in Colombo City by the CCEDD project. However,

other regions/areas still have no full scale SCADA system, except the North Western

Province (NWP) of Region 1, Western Province North, Central Province and Kandy City.

NWP in Region 1 applies a simplified DAS, which can control and indicate the status of

Connecter Type Binding type


2 - 15

the switchgear from a remote control center through a mobile telephone network.

However, the status indication is not updated since it uses GPRS and Global System

for Mobile (GSM) Communications. It also does not communicate the status

periodically. When an operator accesses a remote station, he/she should first confirm

the present status of the switchgear and operate it

next. The Central Province also provides similar

system as the simplified system of Region 1 and the

same type is also provided in the Central Province of

Region 2 as shown in the right photograph.

Recently, Region 2 developed a new SCADA system which applies cyclic data

acquisition from local equipment and data logging. In Region 3, an identical DAS in

Kandy City is under development and will be completed in 2013. The system

configuration of Micro SCADA is shown in Figure 2.3-3.

Figure 2.3-3 Communication method of Micro SCADA

Western Province South-1 (WPS-1) in Region 4 has a

white board with mimic and symbol to indicate and

manually change the status of the switchgear as

shown in the right photograph.

CEB has applied GPRS/GMS to transmit and receive

the data for DAS. Considering the cost, security and

reliability of the system, it is suggested to use a dedicated line on the public telephone

network or dedicated communication link such as optical fiber communication. In the

latest situation in Sri Lanka, it is recommended to apply a fiber optic communication for

Back Bone Communication (BBC) and radio communication such as ZIGBEE or RF

Mesh system for the Last One Mile Communication (LOMC).

The specification of each system is summarized in Table 2.3-7.

(3) Current Status of Distribution Losses and Countermeasures

1) Non-technical losses

Non-technical losses are caused by misreading/error of energy meters, power theft,

street lighting and power supply to the public sector. However, CEB cannot grasp the

quantity of lost energy from LV substations because they do not have proper energy

meters. Therefore CEB calculates the losses from the difference between the input

energy measured at GS/PS and sold energy to consumers. In every region, it was

said that the breakdown of the non-technical losses were unknown.

2) Technical losses

Technical loss is composed of MV distribution losses (about 2%) and LV distribution

losses (about 10%). The MV distribution losses are reported in the MV Development

Study as shown in Table 2.3-8.

However, LV distribution losses were not given in the MV Development Study. CEB

explained that they do not have facilities to measure the energy to input to the LV

distribution line. CEB calculates the lost energy from resistance values and current

values on the LV distribution lines. Accordingly, energy meters are very effective tools

to measure the output energy for each LV distribution lines.

(4) Issues and Concerns to be solved in CEB’s Distribution System

1) Overloading in GSS/PSS

In the CEB’s distribution system, transformers and MV distribution lines do not have

any operation margin in their current capacities. For instance, scheduled shutdowns

are carried out in Kuriyapitiya to prevent overloading the equipment. It is very

important to reinforce the GS, PS and transformers to give an increased margin in

operation. CEB produces the reports on the MV Development Study only every two

years. However, overloading on facilities occur every year. The followings are the

unnoticed problems to be addressed in the development plan.

i) Growth of power demand is more rapidly increasing than expected.

ii) Remarkable delays in the schedule of reinforcement/installation.

iii) Expected margin of facility is too small; and

iv) Low quality of distribution facility due to aging, improper design and poor

equipment quality.

It is recommended to take the soonest action to find the root causes of the problems

and take the countermeasure(s) to solve the above conditions in overloading.

2) Voltage drop

Voltage drop is observed at many locations on CEB’s distribution system. The root

causes of voltage drop are the distribution of electric power on long distribution lines

and overloading. The following three countermeasures are considered to rectify

voltage drop.

i) Provide additional distribution lines and/or size up the conductors;

ii) Construct new GS to shorten the distribution lines; and

iii) Provide voltage compensation facilities such as step voltage regulator (SVR)

If the capacity of the distribution line is sufficient to feed the power to consumers, it is

an economical solution to provide voltage compensation facilities. However,

considering the current situation of CEB, it is recommended to take the option i) and/or

ii).

3) DAS

It is recommended to provide a DAS to the distribution system. If DAS is provided, the


2 - 18

following advantages will be realized in the distribution control and management of CEB.

i) Continuous monitoring of switchgear

It is very essential to indicate the present status of switchgear in the Domestic

Control Center (DCC). Under the present system, the call center received the

claim from consumers and confirms the status of equipment. If DAS is

provided in the DCC, the following activities can be available automatically.

- 24 hours monitoring (no call center)

- Indication of status of switchgear and live/dead conditions of line section

- Support system to instruct fault locations on a map and failed equipment

identification.

ii) Remote control of equipment

Under the present system, the call centers receive the information from

consumers and the control center instructs the operators to visit the site and

change the status of the switchgear. It takes a long time to changeover the

switchgear and to minimize the shut-down section. After the changeover of

the switchgear, the control center may instruct maintenance electricians to

repair the failed equipment. If DAS is provided, it is possible to changeover

the switchgear without visiting the site and the shut-down section can be

minimized. In addition to remote control, it is possible to provide software to

control the switchgear automatically or give suitable instructions to the

operators in accordance to a pre-determined routine. Also, DAS can monitor

the power factor on the system and control the reactive power by switching-in

capacitors.

However, it is essential to provide the operating mechanism in the switchgear in

order to control these by remote signal.

iii) Continuous monitoring for disturbance and control

It is not possible to measure the electric current on each distribution line under

the present system. The DAS can monitor all information on the distribution

lines and it can acknowledge the abnormality on the distribution line even if it is

given by a complicated calculation. For example, in the case of overloading of

a distribution line, DAS automatically detects the changeover of the switchgear

status will be done to even the load current on each line.

iv) Database and reporting

Currently, operators record the status and/or disturbance on a log book or

manually input the record to a PC database. The DAS has the routine function

of recording into the database and can issue a report of any information


2 - 19

automatically or on request. It can also eliminate any human error in

recording and reporting.

v) Intelligent DAS functions

At present, operators monitor the distribution system and make decisions to

control the switchgear through their own skills and knowledge. Intelligent

functions can be provided with the DAS by adding an optional software. For

example, it is possible to issue an alarm easily by an output of calculation, even

if it can be calculated only through a complicated process or equation.

vi) Communication for DAS

At this moment, CEB uses GSM/GPRS for DAS. However, it is not a suitable

communication system for the control of electric power system because of cost,

reliability and security reasons.

4) Provision of energy meters and data transmission

CEB has the static energy meters (Class

1.0) with remote reading facilities for large

consumers through GSM network as

shown in the right figure. Also typical

structure of large consumer is shown in the

photographs below. An operator remotely

accesses the energy meters once a month

to take consumption data one by one.

However, in some distribution substations,

energy meters are not provided, or old

fashioned mechanical types (induction

disk-type meters with class 2.0) are used.

Consequently, it is not possible to measure

energy on LV lines and it takes time to read

the meter indication on site. To analyze

the distribution losses, energy meters are

an effective tool to measure the losses.

In case of resistive losses on distribution

lines, it is possible to calculate the losses

by impedance of the conductor and the load current on a line. Even if meters are to be

provided at distribution substations, operators need a lot of work to go to the sites and

read the meters due to the large numbers of energy meters; more than 1,000 sets are

to be installed at distant place in one local area office. To save time and manpower to

read meters, it is important to add a remote data monitoring system to send the reading

Typical structure of large consumer

of a meter to the Control Center. In addition to the energy meter reading at a

distribution transformer, it is recommended to provide smart metering at each consumer

location in the future.

5) Increase of transformer loss due to inadequate transformer capacity

CEB has standard series of DT capacity of 100 kVA, 160 kVA and 250 kVA. If the

power demand in rural areas is very small at the distribution substation, the minimum

rating of 100 kVA transformers is used for the substation. In this case, no-load loss

(iron loss) is very large because of the too-large transformer rating comparing with the

power demand. If a transformer with adequate capacity such as 30 kVA is used for a

small-demand substation, it is possible to reduce the no-load loss of the transformer.

If a small single phase transformer is applied to the LV feeder with small load, further

reduction of no-load loss is possible.

In addition, if low-loss transformers with the latest technique such as ‘Top Runner

Transformer’ with appropriate capacities are to be applied in the system, these are

expected to remarkably reduce transformer losses.

6) Distribution losses caused by long LV lines

It was confirmed that the length of the LV line to the most distant consumer is 1.8 km

and the total lengths of LV lines connected to one distribution substation are on the

average, 8 km and at maximum, 15 km. The LV lines seem too long and produce

large distribution losses. It is therefore an effective countermeasure to provide

additional LV distribution substations to reduce the lengths of LV lines and accordingly,

decrease the distribution losses.

7) Theft of electric power

Most modus operandi of power theft is hanging a hook on a bare LV wire, because the

density of population is very thin in rural areas and therefore, it is very difficult to notice

such an activity in a wide area. Under the current distribution system of CEB, it is

difficult to discover power theft because electrical energy is not exactly monitored on

the LV line. Therefore, it is recommended to provide energy meters on every LV line

to monitor the branched energy by theft.

8) Resistive losses at connection points on LV lines

It was observed that LV distribution wires were connected by a connector or a manual

winding connection. There are two reasons of connection loss on an LV line. One is

manual connection by an unskilled electrician; it is very difficult to control the skill and

check the connection on site. A worker climbs on the pole alone and carries out the

connection work without appropriate examination. The other reason is the connection

by screw connector; aluminum can be deformed at the screw connector in long duration

and therefore causes improper contact, which results in heating loss by contact

resistance at a connection point. A thermal imaging camera can observe heating at

the connection.

It is necessary to use hydro-compression tools by which proper compression clamp

connection can be done without long-term experience. It is also recommended to

properly train the workers to eliminate defective connection.

9) Rehabilitation of aged facilities

Some existing 11/0.4 kV transformers were manufactured more than 70 years ago and

are still working at 11 kV substations. Considering the current technique level, it is

possible to reduce transformer losses by applying the recent technology.

Rehabilitation/reinforcement of aged facilities is thus one of the options to reduce

distribution losses.

10) Salt contamination along the seaside

Since salt contamination is observed on overhead lines along the seaside, the CEB

applied 33 kV insulators for 11 kV distribution lines to increase the creepage distance of

insulators. As a drastic measure to solve salt contamination, cables should be

adopted to distribution lines instead of overhead conductors. It is effective to reduce

distribution losses through provision of new small unmanned GS or PS to which 132 kV

or 33 kV cable will be connected from 132 kV or 33 kV network to minimize lengths of

11 kV overhead lines.

11) Applicability of low loss transformers

Almost all DTs are supplied in accordance with standard specification of LTL. The

Survey Team has investigated and confirmed whether LTL can supply the DTs with

directional silicon iron core. However, it is very difficult to apply amorphous iron core

for DTs because the design of the amorphous transformers are completely different

from the directional silicon iron core and large changes in production line is required.

In order to be produced amorphous transformer by LTL, technical assistance shall be

required by Japanese manufacturers.

12) Safety issues for site works

Site work for distribution lines is very dangerous.

Normally CEB workers are climbing on the top of poles

by ladders and

carrying out the

work.


2 - 22

(5) Others

1) Street lighting

The power for street lightings is fed from an LV distribution line. Tariff for street

lighting is not paid to the CEB. To reduce the demand, CEB proposes energy saving

activities to the departments concerned in Colombo City.

2) Capacity building

When the Survey Team visited the CEB Training Center, the Deputy General Manager

(DGM) of the Training Center explained that the ‘SynerGEE’ (USA) software has been

used for distribution planning for more than ten years. Extension of the license is

made every year and each regional office has the license. It is considered that to

support to provide other software for distribution planning is not necessary because

CEB is accustomed to and satisfied with SynerGEE. Meanwhile the DGM of the

Training Center requested the Survey Team to supply hydro compression tools for

connecting distribution conductors and to train electricians how to correctly use the

tools to reduce distribution loss. The Survey Team supposes that it is very effective

for loss reduction.

3) Billing system to consumers

CEB has several area offices in each province. Meter readers of CEB visit each

consumer once every month to read energy meters and issue the bills to CEB’s billing

center. The billing center mails official bills to consumers in due course. Each

consumer pays the bill by several methods such as direct payment at CEB area office,

at super market or by bank account. If consumer does not pay the bill, CEB issues the

“Red Notice” to the consumer and may stop electricity when he does not pay the bill

within the decided time.

Almost all meters for small consumers are electro-magnetic type with accuracy class

2.0. CEB does not accurate the meters periodically then they only goes to consumer

when they send claim to the service center or a meter reader find a problem during

meter reading. The Survey Team has found the several problems in current billing

system as follows;

- Failure of energy meters produces lots of non-technical losses.

- Poor accuracy class of energy meter may produce much non-technical losses.

- It is difficult to find the problems in energy meters until it shows remarkable error.

2.4 Development Plans

2.4.1 Long-Term Transmission Development Plan

The Transmission Planning of CEB has been preparing the Long-term Transmission

Development Plan (LTTDP) 2011-2020. The objectives of the LTTDP 2011-2020 are:

1) To formulate the required transmission development to ensure a reliable and stable

power system for the period year 2011 – 2020 and the planned implementation dates.

2) To estimate the investment cost of the transmission development within the period from

year 2011 to 2020.

The LTTDP 2011-2020 has been prepared as a result of power system analysis, considering

the current issues described in Sub-section 2.3.2, and based on the national power and

energy demand forecast as well as the long-term generation expansion plan.

Chapter 5 of the LTTDP 2011-2020 includes transmission expansion proposals with the

following three categories:

1) Uncommitted transmission development proposals

The transmission network expansion proposals, which are identified as a result of the

system analysis done by CEB Transmission Planning, include two kinds of project lists;

one is the list of already committed and being implemented projects, and the other is

the list of uncommitted projects.

2) Power plant connection proposals

This includes transmission system development required for power plant developments.

3) Other transmission development proposals

Apart from the above transmission system expansion and reinforcement proposals,

other proposals include minor system improvements or renewal needs to enhance the

operational and maintenance aspects of the transmission system.

Among the proposals mentioned above, the Survey Team agreed with CEB to take the list of

uncommitted projects of transmission development proposal as the long list for the candidate

subprojects for Japan’s Loan Aid as shown in Table 2.4-1.

2.4.2 Distribution Line Development Plans

The CEB plans several MV distribution projects in the MV Development Study, which are

prepared by each distribution region and issued every two years. However, any

development plan for low voltage distribution system is not included in the MV Development

Study. The MV Development Study include the construction of new PSs and MV

distribution lines, augmentation and rehabilitation of the existing system to reduce the

distribution losses and improve reliability of the distribution system.

1) Methodology of Planning

CEB plans several development projects to be evaluated by computer based modeling

using the planning software SynerGEE ver. 3.52/36 in the following process.


2 - 26

Step 1 Data collection of network and load data

Step 2 Modeling of existing distribution network and analysis of existing system

Step 3 Network load assessments and load forecasting

Step 4 Modeling of future loads and simulation of various MV network enhancement

option to select optimum techno-economic solution, analysis of simulated

network

The development plans are formulated according to the load and power forecasting

based on computer-aided planning.

2) MV Development Study

After forecasting future system analysis and planning, followed by referring planning

criteria, the proposal will be produced. Upon economic evaluation of candidate

projects, the final project proposals are selected.

Table 2.4-2 shows the MV development projects proposed by each regional office.

2.5 Other Donors’ Assistance

(1) Asian Development Bank (ADB)

Since 1998, ADB’s assistance in Sri Lanka’s power sector has focused on expanding the


2 - 27

infrastructure as well as strengthening CEB and LECO, while providing complementary

support for power reforms. For example, ADB has supported CEB in strengthening its

transmission and distribution systems and expanded rural electrification.

The power sector strategies of ADB are based on Sri Lanka’s development policy framework

(namely, Mahinda Chintana), with the recent one being in 2010. The framework provides a

comprehensive sector development road map, including long-term investment programs,

policies, and reform measures. The goal of Sri Lanka’s power sector is to provide improved

service delivery to the entire population by the end of 2012, such as by providing reliable

services and reducing the cost of service delivery. On such basis, ADB’s assistance

focuses on renewable energy development (including wind and other clean energy sources),

energy efficiency improvement, improving the efficiency of transmission and distribution

systems, and improving energy access for lagging regions. ADB will work with the

government in reducing system losses through improved metering efficiency and better

management systems. ADB will also help the government in creating an enabling

environment for clean power development through sector reforms and PPPs. Table 2.5-1

below shows the strategy of ADB for the energy sector in Sri Lanka.

(2) World Bank

The World Bank (WB) is currently implementing 13 projects totaling US$ 1.068 billion. In

the power sector, WB has contributed to increasing the availability of electricity in rural areas

and energy supply from renewable sources. For example, access to electricity in rural

areas has expanded with the support of the Renewable Energy for Rural Economic

Development Project1.

The WB will support the government’s efforts to address the challenges for achieving its

vision by: (i) facilitating sustained private and public investment through improving the

investment environment and increasing fiscal space and public spending efficiency, (ii)

supporting structural changes of the economy through assistance for a knowledge-based

economy, and increased internal and international integration and competitiveness, and (iii)

promoting improved living standards and social inclusion by improving the quality of services,

reducing malnutrition and promoting social inclusion.

(3) China

Since the end of the civil war in 2009, there has been a noticeable increase in Chinese

lending, with almost US$ 6.5 billion being invested primarily in infrastructural projects,

making China a major player in Sri Lanka’s development. China’s loans to Sri Lanka are

neither at preferential rates nor as grants-in-aid, but offers a grace period of 4-5 years for

repayment.

According to the Annual Report 2011 from the Ministry of Financing and Planning of Sri

Lanka, the total project portfolio funded by China in 2011 was US$ 2,522 million. The

power and energy sector was the second largest amount of the total portfolio, being 20 % of

the total. Also in 2011, the China Development Bank Corporation agreed to provide

US$ 1.5 billion over a three year period for roads, power plants and irrigation schemes.

1 By this project, 139,241 new rural households have access to electricity (committed amount US$ 75 million).

Figure 2.5-1 Chinese Assistance to Sri Lanka 2011

In addition to the above, China is expected to contribute about US$ 10 billion, which is

almost half the amount that Sri Lanka is expected to spend during 2012-2015 for

infrastructure development.

In power generation, China National Machinery and Equipment Corporation constructed the

first phase of the 900 MW plant (three 300 MW coal power plant) in the Norochcholai area,

which was under a LKR 51,415 million loan from China’s Export and Import (EXIM) Bank.

Moreover, approval has been given to proceed with the construction of Broadlands

Hydropower Project. This is a 35 MW hydropower project in the Kelani River, located in the

Central and Sabaragamuwa Provinces. The estimated construction cost was US$ 103

million but a Chinese contractor, China National Electric Equipment Ltd, has undertaken the

project cost for US$ 82 million and is scheduled to be completed in 2014. According to the

Ceylon Electricity Board, this project will minimize the carbon dioxide emission to the

environment, decreasing it by 80,000 tons per annum, earning for the country US$ 2.4

million in carbon trading.

(4) Iran

Iran has been funding a number of infrastructure development projects in Sri Lanka. For

example, it shall provide assistance in doubling the capacity of the Sapugaskanda Oil

Refinery, the creation of a 100 MW hydropower project, and to the Uma Oya Multipurpose

Development Project2.

In the power sector, Iran has expressed its stance to continue financial and technical aid for

rural electrification projects to strengthen the electricity supply to remote villages of Sri Lanka.

2 Construction of two dams across two main tributaries of Uma Oya at Welimada and Dyraaba and a 23 km long trans basin

diversion tunnel with an underground power station at Randeniya.


2 - 30

These projects, also called the Rural Electrification Project–8 scheme, will electrify a

thousand villages in eleven CEB provinces: North West, Central, Western North, Eastern,

West South, West South–II, Sabaragamuwa and Southern Provinces. The expected

completion date of the project is June 2012 and the total estimated cost is US$ 106.5 million.

The proposed contractor for this project is Sunir Co. of Iran and supplies all the materials

except the RC pre-stressed poles, which will be procured by CEB. The project is expected

to bring benefits to about 180,000 rural households.

(5) India

The National Thermal Power Corporation Limited (NTPC), the largest thermal power

generation utility of India and CEB signed the joint venture and shareholder agreement to set

up Coal Thermal Power Plant at Sampur in September 2011. The power plant at Sampur

has a total capacity of 500 MW with two generating units of 250 MW each. The project is a

fifty-fifty joint venture between CEB and NTPC. The power plant at Sampur with a total

investment being US$ 500 million, would be Sri Lanka’s second coal-fired power plant.

The Government of Sri Lanka has allocated a 500 acre land in Sampur for the site and will

construct the coal unloading jetty and install related equipment. The Government of India

has offered a concessional line of US$ 200 million to Sri Lanka to expedite the construction.

It is expected that the issuance of tenders for construction will be made by the end of 2012

and completion will be by the end of 2016.

Together with the list above, CEB has compiled proposals for each project. On the basis of

the submitted proposals, the Survey Team carefully studied the development plan proposed

by CEB and evaluated them based on the degree of their contribution to the improvement

and reliability of transmission systems in Sri Lanka. Distribution projects proposed by CEB

are examined in Chapter 4.

3.2 Proposed Transmission Projects

This section describes the contents of the project proposals submitted by CEB. Project

scopes and costs, which are modified and adjusted by the Survey Team, are described in

Chapter 7.

3.2.1 Colombo City Transmission Development (PJT-1)

(1) Objective

At present, electric power in Colombo City is supplied by Colombo A (Havelock Town),


3 - 2

Colombo C (Kotahena), Colombo E (Kollupitiya), Colombo F (Fort), Colombo I (Maradana),

132/11 kV GSs and Kolonnawa and Kelenitissa 132/33 kV GSs. The present demand for

the GSs is approximately 318 MVA in total. However, it is expected that there are some

urban development plans which require larger power demand in Colombo City in the near

future.

According to the demand forecast prepared by CEB, of which extract is shown in Table 2.3-2

of Chapter 2, approximately 120 MVA demand is to be added to the Colombo City network

by 2015 and 357 MVA demand is to be added by 2020. Therefore, the transmission

network development for Colombo City needs to be implemented to meet the demand

growth. In addition, it is expected to realize improved quality and reliability of power supply

in Colombo City.

Figure 3.2-1 shows outline of the project proposed by CEB.

(Source: Project Proposal, CEB Transmission Planning)

Figure 3.2-1 Outline of Colombo City Transmission Development

According to CEB’s proposal, the project is planned to be implemented in two phases. The

green colored dotted line shows the second phase of development. It is further proposed to

use the existing oil-filled copper 500 mm2 cables to ensure N-1 reliability to Colombo E GS

until the second phase is completed.

At present, the aforementioned existing 132/11 kV GSs are supplied with electric power by

Kelanitissa and Pannipitiya 220 kV GSs. At present, inter-bus transformers with the

capacity of 2x150 MVA and 2x250 MVA are installed at Kelanitissa and Pannipitiya GSs,

respectively. To meet the rapidly increasing demand forecasted in the future, it is further

planned that another 220/132 kV, 2x250 MVA GS will be introduced at Colombo Port where

major part of the expected future demand of Colombo City is concentrated. Moreover, it is

proposed to connect Kerawalapitiya and Kelanitissa Power Plants to the proposed Port GS

to enhance the reliability of the Colombo City supply. Figure 3.2-2 shows the planned cable

line route under the project.

(4) Effect of Transmission Loss Reduction studied by CEB

CEB has calculated loss reduction values on assumptions that load of the proposed GSs

(Colombo L, M and N) were transferred to the existing GSs (Colombo E, F, B, C and

Kelenitissa) by 2015 and by 2020 in the case without the project. Loads considered for

Colombo B, C, E, F and Kelenitissa GSs in the case without the project are shown in Table

3.2-2.

3.2.2 Construction of Kappalthurai GS (PJT-2)

(1) Objective

At present, the capacity of the Trincomalee GS is 63 MVA. According to the demand

forecast, Trincomalee GS shall be augmented to 94.5 MVA by 2013 and to 126 MVA by 2020.

However, it is difficult to augment the existing GS due to the limitation of space.

Therefore, in order to meet the growing demand in Nilaweli and Kappalthurai areas and the

proposed Kappalthurai special economic zone, it is proposed to construct a new GS at

Kappalthurai with two 31.5 MVA transformers and eight 33 kV feeders in 2014 to relieve the

loading of Trincomalee GS. The proposed GSs will also improve the voltage profile of 33

kV distribution systems and therefore improve the quality of supply in and around the areas.

This new GS is proposed to connect to the existing New Anuradhapura-Trincomalee 132 kV

line using double in and out connection as shown in Figure 3.2-3.

these areas, the loading of Kotugoda GS will be 90 % in 2011 and also 181 % under outage

of one transformer. Furthermore Kotugoda GS is expected to reach 126 % load under

outage of a 60 MVA transformer by 2017 even after the expansion of the GS in 2012.

Since Kotugoda GS is located at a highly industrialized area, it has to be able to cater to the

demand under outage of one unit. Therefore, it is proposed to construct a new GS at

Kerawalapitiya with 2x35 MVA transformers and eight 33 kV feeders in terms of improving

reliability of the regional distribution system and meeting the growing demand in 2014.

3.2.4 Reconstruction of Kiribathkumbura 132/33 kV GS (PJT-4)

(1) Objective

Kiribathkumbura GS commissioned in 1986 was the first 33 kV GIS substation of CEB. In

2003, the substation was expanded by adding a third 31.5 MVA transformer and 4x5 MVar

capacitor banks. At present, 3x31.5 MVA Kiribathkumbura GS feeds electric power to many

important government and commercial establishments in the Kandy area. According to

statistical data, the anticipated load growth rate of the area is 5.0 %.

It is reported that all 132 kV bays of the substation have operational problems, except for

No.1 of Kurunegala line bay, No.2 of Ukuwela line bay and No.3 of the transformer bay.

The number of operations of 33 kV switchgears has exceeded the recommended 10,000

operations. In addition, 11 units of 33 kV GIS switchgear have already exceeded their

service life of 25 years which is 2.5 times of the recommended service life (10 years).

Hence, these switchgear units need overhauling according to the operation and maintenance

(O&M) manual. Furthermore, the price quoted by the manufacturer for inspection and

overhauling was excessive according to the O&M Branch of the CEB Transmission Division.

In addition, the existing protection system which comprises electromagnetic type of relays

has many operational problems. Furthermore, aging equipment and unavailability of spare

parts have caused the low reliability of Kiribathkumbura GS.

After an assessment of the condition, the Asset Management Branch of the Transmission

Division has recommended the rehabilitation of Kiribathkumbura GS. Therefore, it is

proposed to rehabilitate Kiribathkumbura GS in order to improve the quality and reliability of

the electricity supply.

construction of the transmission line, will approximately be 4.9 % in the Day Thermal case at

the highest value.

3.2.6 Construction of Chemmuni GS (PJT-6)

(1) Objective

Since the Jaffna Peninsula is presently isolated from the national grid, electric power to

Jaffna Peninsula is supplied by CEB and privately owned generators. Due to the

inadequacy of the present generation, power supply in Jaffna is partly interrupted during the

peak hours. To overcome this situation, a new 2x31.5 MVA 132/33 kV GS at Chunnakam

and a 67 km, 132 kV transmission line from Kilinochchi to Chunnakam are under

construction.

The objective of this project is to meet the growing electricity demand in Vaddukkodda,

Chavakachcheriya, Kankasanthurai, Point Pedro and Jaffna areas by providing quality and

reliable supplies and to connect the proposed Chemmuni GS to the national grid as shown in

Figure 3.2-5.

3.2.7 Construction of Kalutara GS (PJT-7)

(1) Objective

Kalutara area is mainly fed by Panadura and Matugama GSs with long distance 33 kV

distribution lines, which cause high distribution losses. According to the demand forecast,

the loading of Panadura GS will be 90 % in 2014 and also 128 % under outage of one

transformer. Panadura GS will be overloaded by 2016 even after the expansion of the GS.

On the other hand, the loading of Matugama GS will be 94 % in 2014 and also 134 % under

outage of one transformer and it will be further overloaded by 2016. In order to meet the

growing electricity demand while minimizing distribution losses and relieve loading of

Panadura and Matugama GSs, it is proposed to construct a new GS at Kalutara with two

31.5 MVA transformers and eight 33 kV feeders.

Proposed GSs will improve the voltage profile of the 33 kV distribution system and reduce

distribution losses and therefore improve the quality of supply in and around the Kalutara

areas. This new GS is proposed to connect to the existing Pannipitiya – Matugama 132 kV


3 - 15

TL using single in and out connection as shown in Figure 3.2-6. This project will reduce

losses, improve the reliability of the system and meet the growing demand in the area.

3.2.8 Construction of Battaramulla GS (PJT-8)

(1) Objective

At present Sri Jayawardhanepura Kotte demand, which is approximately 50 MVA, is mainly

fed from Sri Jayawardhanepura 132/33 kV GS. There is a future development plan around

the Battaramulla area. CEB has projected the required demand for the development plan

as 114 MW in 2025. As a result of the study for the development, CEB has proposed to

implement augmentation of the existing Sri Jayawardhanepura GS and the construction of a

new Battaramulla GS in the vicinity of the existing GS. The capacity of Sri

Jayawardhanepura GS is to be increased to 94.5 MVA. In the meantime, the capacity of

the new Battaramulla GS is to be planed as 63 MVA. These capacities can meet the rapidly

increasing demand by 2017.

Sri Jayawardhanepura GS is presently fed from Kolonnawa - Pannipitiya 132 kV Lynx line by

double “T” connection. Since Battaramulla GS is proposed in the same area, it can be

connected to the same line by opening the existing connection as shown in Figure 3.2-7.

3.2.9 Reconstruction of Old Anuradhapura GS (PJT-9)

(1) Objective

Old Anuradhapura GS is situated in the North Central Province. Annual energy demand of

the GS is 138 GWh and the estimated load growth is 4.7%. At present, Old Anuradhapura

GS feeds power to Nochchiyagama, Periyankulama, Horowpathana, Medawachchiya and

Mihintale areas and some parts of the Vavuniya area.

Old Anuradhapura GS consists of 2x10 MVA transformers which were commissioned in 1969


3 - 18

and 1975, and a 31.5 MVA transformer which was commissioned in 1996. At present, Old

Anuradhapura GS is connected to New Anuradhapura, Habarana and Puttalam GSs with

132 kV double circuit transmission lines. No rehabilitation or any augmentation work has

been carried out at this GS since 1996.

It is reported that Old Anuradhapura GS has many operational problems. Almost all of the

equipment in the GS is now 40 years old and spare parts are not available. After a

complete condition assessment, the Asset Management Branch and the Operation &

Maintenance Branch of the Transmission Division of CEB have recommended to augment

Old Anuradhapura GS.

Furthermore, it has been planned to transfer connections of Puttalam and Habarana 132 kV

transmission lines to New Anuradhapura GS and to rearrange Old Anuradhapura GS.

Hence, in the future, Old Anuradhapura GS will be fed from New Anuradhapura GS by 132

kV double circuit transmission line. Further, to cater the increasing demand in and around

Anuradhapura City it has been decided to augment Old Anuradhapura GS with 2x45 MVA

transformers.

Therefore, it is proposed to augment Old Anuradhapura GS in order to ensure the quality

and reliability of the electricity supply and to cater the growing demand.

3.2.10 Construction of Nawalapitiya GS (PJT-10)

(1) Objective

In Sri Lanka, there is a policy target of obtaining 20% of energy from non conventional

renewable energy resources by 2020. In this context, mini-hydro power plants play a key

role. A large part of mini-hydro potential of Sri Lanka exists in the Central Hills and a large

number of mini-hydro projects have been identified in Nawalapitiya, Kotmale, Galaha and

Ginigathhena areas. However, the GSs existing in the area; Nuwara Eliya and

Wimalasurendra are unable to send power from any new projects because the GS capacities

have already been exceeded. Therefore, the requirement of a GS at Nawalapitiya is urgent

and important to accommodate new mini-hydro power plants.

At present, Nawalapitiya area is fed from Kiribathkumbura GS which is approximately 30 km

away. To meet the increasing demand, Nawalapitiya GS is required to be constructed by

2017. This will relieve the loading in Kiribathkumbura GS and high losses in the distribution

network. Nawalapitiya GS will also improve the voltage profile of the 33 kV distribution

system in and around Nawalapitiya area and thereby improve the quality of supply in the

area.

Hence, the construction of Nawalapitiya GS is important in order to accommodate renewable

energy, to meet the growing demand, and to improve the quality of supply in and around

Nawalapitiya area.

3.2.11 Construction of Wewalwatta GS (PJT-11)

(1) Objective

There is a large potential of mini-hydro capacity that can be harnessed in and around the

Balangoda and Ratnapura areas. At present existing Ratnapura and Balangoda GSs are

both being augmented to 3 x 31.5 MVA so as to send capacity of 150 MW generated by mini-

hydro which can be harnessed around the area.

According to information provided by CEB, Ratnapura and Balangoda GSs will exceed their

allowable connection capacity by 2016 even after their augmentations. Because there is

capacity limitation in the existing GSs, grid interconnection of mini-hydro projects is restricted

in these areas. Therefore, construction of a new GS has been proposed in this area.

Wewalwatta area has been identified as a potential site for the interconnection of about 25

MW of mini-hydro power plants and is located between Ratnapura and Balangoda GSs close

to the existing 132 kV Balangoda - Ratnapura transmission line. The new GS can be

connected to the existing Balangoda - Ratnapura 132 kV transmission line.

3.2.12 Construction of Tissamaharama GS (PJT-12)

(1) Objective

Tissamaharama GS is planned to be constructed in the Southern Province. The annual

energy demand of the Southern Province is 760 GWh. The Tissamaharama and

Katharagama areas are presently fed from Hambantota GS, with an alternative supply from

Embilipitiya GS via Thanamalvila. However, these distribution lines are very long and the

load of Katharagama is connected at the end of the distribution line. Hence, these areas

experience serious voltage drops. The situation may become critical with the load growth in

the areas in the near future.

Tissamaharama GS will relieve overloads of Hambantota GS, where the load growth in the

area is considerably high due to the development activities planned in the area. These

development activities include the Hambantota Harbor, Mattala Airport, Mirijjawila Industrial

Park, Mirijjawila salt- based industries, and Mirijjawila oil refinery.

In accordance with the forecasted demand to be increased in the area by 2025, it has been

proposed to construct a new GS at Tissamaharama in 2016 to overcome the critical voltage

drop issues at the Tissamaharama and Katharagama areas and to relieve loads of

Hambantota GS. Tissamaharama GS is proposed to connect to the national grid at

Hambantota GS using double circuit 132 kV transmission line.

As a result of the discussion with CEB considering the result of the evaluation, the following

project components were selected as the candidate projects:

1) Colombo City Transmission Development (PJT-1)

2) Construction of Kappalturai 132/33 kV GS (PJT-2)

3) Construction of Kerawalapitiya 220/33 kV GS (PJT-3)

4) Construction of Veyangoda – Kirindiwela – Padukka 220 kV TL (PJT-5)

5) Construction of Kalutara 132/33 kV GS (PJT-7)

6) Construction of Battaramulla 132/33 kV GS with related TL (PJT-8)

The selected candidate projects have scored more than 14 points in total. As these projects

are regarded as worth developing, they shall be carefully evaluated in the following chapters.

Projects that scored less than 10 points are not regarded as important to be studied by CEB

and thus the Survey Team also has not conducted further studies.

Regarding project packaging, it is reasonable and feasible to combine PJT-3, PJT-7 and

PJT-8, since each project area is in the vicinity of Colombo City and thus, is expected to add

increased benefit due to their combination.

As a result, the Survey Team proposed to further study the feasibility of the following

projects:

1) Colombo City Transmission Development (PJT-1)

2) Construction of Kappalturai 132/33 kV GS (PJT-2)

3) Construction of Kerawalapitiya 220/33 kV GS (PJT-3)

CHAPTER 4 DISTRIBUTION LINE PROJECTS

4.1 General

The Survey Team has received project proposals for the development of distribution lines

including MV, LV and DAS/AMR projects, which were prepared by each distribution region of

CEB. In addition, the Survey Team has investigated further requirements through

interviews with each regional office. As a result of the discussion with CEB concerning the

proposals, plans, and requirements, the Survey Team has nominated the following sub-

projects that will contribute to loss reduction.

1) New LV Substation (LV scheme)

The density of consumers is very thin in Sri Lanka, resulting in making LV lines long,

Thus causing major distribution losses. It would be very effective to provide additional

LV substations to reduce distribution losses. Details of the location and quantity of LV

substations shall be carefully studied and then selected. Basically, this activity shall

be considered into Distribution Loss Reduction Project. Additional loss reduction can

be obtained by using low loss type transformers for distribution transformers (DTs).

2) Single-phase to Three-phase Conversion

When single-phase circuit is converted to three-phase circuit, the maximum distributed

power can be three times than that of the single-phase circuit, and thus the load current

can be reduced by a third. Accordingly, the resistive loss can be reduced to a sixth

considering three wires for three-phase distribution lines. It is necessary to design the

consumer’s connections to balance the load current on each phase in order to make it

effective.

3) Auto Meter Reading (AMR)

At this moment, CEB does not have an automatic meter reading at DTs. CEB has

energy meters for large bulk consumers only. These energy meters have remote

monitoring facilities using Global System for Mobile (GSM) communications. CEB has

planned to provide the energy meters at the DTs to monitor the energy flow. The

technical losses of the distribution system cannot be reduced by providing energy

meters, but it can increase the ability to measure the distribution losses such as

technical and non-technical losses. It is possible to grasp the non-technical losses on

the distribution system and reduce power theft by monitoring and comparing input

energy to consumers billing. In the future, all energy meters will be provided at each

consumer as smart metering.

GRPS/GSM communications system is applied to the existing DAS system and CEB


4 - 2

planned to apply the same system for AMR. However, considering its reliability, the

Survey Team recommends to apply fiber optic communication as the “Back Bone

Communication” and radio communication such as Zigbee or RF Mesh for the “Last

One Mile Communication”.

4) New 33/11 kV PS and Reinforcement of Distribution Line

Construction of new 33/11 kV PS and reinforcement of MV distribution lines, which may

contribute to distribution loss reduction, are to be recommended. The major

contribution is resistive loss reduction by decreasing the load current and upgrading the

system voltage, and rectification of overloading to balance the load current on each MV

line. As a supplemental effect, reliability of the distribution system will improve and

lead to the reduction of overloading and blackouts. The final nomination of projects

will be done in a later stage after detailed analysis and evaluation.

5) Distribution Automation System (DAS)

Although DAS is not mentioned in MV Development Plan, the Survey Team found the

need through the project proposals and meetings with Regions 2 and 3.

DAS is a convenient tool to control the load current on distribution systems, to select

the best operation options, and to minimize distribution losses. DAS has intelligent

functions, for example, it is possible to know the latest distribution losses, which are

calculated from energy meters. Also, DAS has several supplemental advantages,

such as savings on labor, minimizing shut-down area, increasing reliability and

automatic logging and reporting.

New simplified DAS developed by CEB has remarkable progress from the existing fully

manual operation. It can monitor the switchgear status, alarm and current/voltage,

power factor and other control data obtained through simplified DAS. The so called

“Full-scale DAS” produced by major manufactures have superior functions in

accessibility, reliability, security and maintainability. Here, in the next step from

simplified “Mini SCADA” or “Micro SCADA” system, the Survey Team strongly

recommends to provide “Full scale DAS” for CEB. In addition, it is economical and

functional to combine the DAS and AMR system, for it is possible to use the same

communication links together.

On the other hand, the Survey Team has the subject to provide communication links

between the remote terminal units (RTUs) and the distribution control center. CEB

has used GSM/GPRS network in a very low cost of about US$ 3.0/month per terminal.

Communication links can be realized with a combination of the public telephone

network and GSM/GPRS network. However, CEB has already experienced that there

are several inconveniences and problems in GSM/GPRS communication system.


4 - 3

6) Specialized Vehicles

At present, CEB’s maintenance staff use normal trucks and wooden radars for site

works at the top of the pole. They also use normal trucks and cranes to install

distribution poles at road sides. This is very dangerous and ineffective and therefore,

if the staff uses insulation bucket trucks and pole installation trucks for site works, safe

and efficient work can be assured. Therefore, the Survey Team suggests supplying

such trucks as shown in the following photographs.

To maximize the loss reduction effects, the distribution projects were mainly selected in

collaboration with the transmission projects as mentioned in Chapter 3 and may be grouped

to one distribution project including DAS and AMR, switchgear and MV lines to make them

effective as total system. The final proposal is described in Section 4.2 after detailed

investigation, discussions with CEB, and technical and economic studies.

4.2 Proposed Distribution Projects

4.2.1 New LV Schemes

(1) Small Capacity Distribution Transformers

1) Present situation of loading on DTs

DTs step down MV (33 or 11 kV in Sri Lanka)

to LV (415 V). DTs on overhead lines are of

the single-pole or double-pole mounted type.

Pole mounted DTs have a series of capacities

of 100 kVA, 160 kVA, 250 kVA, 400 kVA, and

others up to 1,000 kVA, with power fuses,

lightning arresters, disconnectors and energy

meters. LV lines from DTs have the length

from several hundred meters to 1.8 km to the most distant consumers.

On the other hand, in Japan, the DTs are only single-pole mounted type and smaller in

capacity than Sri Lankan DTs, such as 10 kVA to 100 kVA, and the length of the LV line


4 - 4

is shorter than that of CEB. In addition, if Japan’s technologies such as “Top Runner

Transformers” are to be applied, further loss reduction can be realized.

Figure 4.2-1 Loss Reduction by Small Transformers

2) Project scope of small DT installation

CEB has a series of standard capacities of DTs of which the minimum capacity is three

phase 100 kVA. However, a bigger capacity is used for smaller loads in some cases.

It may cause much no-load (iron) losses as pointed out in Region 3. If it is replaced by

a small sized single-phase transformer, it may be possible to reduce no-load losses.

On the other hand, load-losses on LV lines shall not be changed substantially because

such a small loaded feeder is almost single-phase. Heavily loaded single-phase lines

shall be converted to three-phase lines, and small sized single-phase DTs can be used

for small loaded single-phase lines without increasing much losses.

(2) Addition of LV Scheme

1) Present situation of LV distribution substation (LV Scheme)

In rural areas, the length of the LV distribution line is very long beyond determined

maximum length by CEB. It is very effective to provide one new LV Scheme between

the existing substations in order to shorten the LV lines and reduce the losses. Typical

daily load curves of rural areas and average load curve of Region 3 are shown in Figure

4.2-2.

2) Project of additional LV Scheme installation

It is possible to reduce the losses by installing LV Scheme as shown in Figure 4.2-3.

In case the lengths of LV line up to the end consumers are longer than determined

lengths, it should be selected to add new LV schemes as shown in Table 4.2-1.

Although Regions 2 and 3 of CEB proposed the project for LV schemes as shown in the

table, the Survey Team assumed the latent demand of LV schemes in other regions.

4.2.2 Single-phase to Three-phase Conversion

(1) Present Situation of LV Lines

In Sri Lanka, three-phase four wire system is adopted

for LV lines, but many single-phase two wire systems

still remain in rural areas. The conversion from

single-phase to three-phase is being carried out one

by one at this moment, thus it may take substantial

time to convert a single-phase line to three-phase line.

The losses on LV lines can be reduced to 1/6 times

as shown in Figure 4.2-4.


Figure 4.2-4 Three-phase Conversion

(2) Project Scope for Single-phase to Three-phase Conversion

It is possible to reduce the losses by converting the existing single-phase lines to three-

phase lines. The Survey Team assumed that this measure is to be adopted in WPN, CP

and eastern of Region-2, and WPS-2, UVA and Sabaragamuwa of Region-3. However, the

Survey Team believed there is latent demand in Regions 1 and 4.

4.2.3 Provision of Automatic Meters Reading (AMR)

(1) Present Situation

The existing mechanical type energy meter on site and the electronic energy meter, which

are currently used are shown in the following photographs for reference. At this stage, the

energy meters have no remote monitoring facilities except for large bulk consumers. The

communication used for remote monitoring of large bulk consumers is GSM/GPRS.

(2) Requirement of AMR

Although only Region 4 has submitted the proposal of AMR at DTs, the Survey Team has

confirmed the needs of AMR at DTs through discussions with other regions. The proposal

and latent demand are shown in Table 4.2-3.

(Source: CEB Project Proposals of Region-4 and discussion with each region)

(3) Future Provision of “Smart Meter”

If smart meters can be provided at each consumer site, all information of energy flow can be

identified by CEB. Technical and non-technical losses can be monitored, especially,

power theft can be detected instantaneously and prevented completely.

4.2.4 Provision of New PSs and Reinforcement of Distribution Lines

Upgrading system voltage is one of the effective measures to reduce distribution losses. If

the system voltage is upgraded, it is possible to reduce load currents on the distribution lines

and resistive losses on the line. Upsizing conductors or installing additional distribution

lines is also one of the effective measures to reduce resistance of distribution lines.

Therefore, the Survey Team selected the projects to provide new PSs and the associated

new 33 kV distribution lines.

4.3 Packaged Distribution Projects

Individual loss reduction projects have been described in the above sections. Considering

the features of a distribution system, the individual projects are spread all over the country.

Thus, it is difficult to control and manage the projects and moreover, the total effect of the

projects cannot be measured. The Survey Team proposes to concentrate the projects into

one package in one province, considering the project priority of CEB, the multiplier effect

between each individual project, and its relation to the transmission project as shown in

Table 4.3-1.

electricity demand is rapidly increasing in these areas, the provision of DAS and other

control systems with advanced technology, and reinforcement of the MV system are

necessary.

CHAPTER 5 POWER FLOW AND LOSS REDUCTION CALCULATIONS

5.1 General

To evaluate the effects of the candidate transmission projects as mentioned in Section 3.3,

the Survey Team carried out power flow and loss reduction calculations.

Transmission line projects, such as PJT-1 and PJT-5, are intended to reduce transmission

losses, which are calculated using software for power system analysis, such as PSS/E.

Loss reduction values for transmission projects are calculated to compare the results

between with and without project cases.

On the other hand, grid substation construction projects aim to reduce distribution losses by

shortening medium voltage (MV) distribution lines. Loss reduction values of the grid

substation projects are to be calculated based on the forecasted demand and supposed MV

feeder line length from the related grid substations. Details of the calculations are

described in the following sections.

Calculated loss reduction values are to be used for economic evaluations of the candidate

projects described in Chapter 10.

5.1.1 Power Flow Calculations for Transmission Projects

The power flow calculations validate the status of the future CEB’s transmission network,

especially for the 220 kV and 132 kV transmission lines to be developed under the candidate

projects. The active and reactive power flows on transmission lines, voltages, and phase

angles at each bus in power stations and grid substations are to be simulated in the

calculations. The objective of the power flow calculations is to compare the transmission

loss values between with and without the candidate transmission line projects.

The Transmission Planning of CEB has provided all necessary data on the existing and

future network required to calculate results in 2012, 2015, and 2020, using the PSS/E format.

Such data include line constants, transformer capacities, generating conditions, substation

loads, static capacitors, and shunt reactors, etc. The Survey Team has built future network

models for with and without the candidate projects that are suitable to calculate results for

2015 and 2020, based on the provided data, development plans and demand forecast.

The Survey Team has carried out power flow calculations using “PSS/ETM version 33”

software with the following technical criteria for transmission network planning:


5 - 2

1) Power Flow

Under normal operating conditions, the loading of transmission lines shall not exceed

the thermal ratings calculated at a maximum operating temperature of 75 °C or 54 °C

for some old lines, as shown in Table 2.3-3 in Chapter 2. In case of a single circuit

fault for the interval with more than double circuits, the power flow of remaining facilities

must be within the rated capacity (N-1 criteria).

Under normal operating conditions, the loading of transformers shall not exceed the

rated capacity of transformers allowed by the available mode of cooling. Under N-1

contingency conditions, a short period (one hour) of overloading of up to 120% rated

capacity is allowed.

2) System Voltage

Bus voltage for power stations/substations must be in the range from 95 % to 105 % at

normal operating conditions, and in the range from 90% to 110 % at N-1 condition.

5.1.2 Loss Reduction Calculations for Substation Projects

Since it is difficult to estimate loss reduction values of candidate substation projects with the

power flow calculations, the Survey Team estimated the values with the following methods.

(1) Losses on MV Distribution Lines

Candidate substation projects contribute to the reduction of MV distribution losses. Figure

5.1-2 shows the concepts of the loss reduction calculation on the MV lines.

1) Demand forecasts for the existing and new substations up to 2025 are given by CEB.

2) In case that candidate substation (C GS) is not constructed in some areas, neighboring

existing substations (A and B GSs) shall supply electric power to said areas via long-

distance MV distribution lines (without the project case).

3) In case the candidate substation is constructed in the area as mentioned above, MV

distribution lines from the existing substations can be shortened (with the project case).

Loss reduction values can be calculated to examine differences in distribution losses

between “with the project” and “without the project”.

4) Annual MV line losses (MWh/year) can be calculated using the following formula:

Annual MV line loss = NC x L x NCC x R x I2 x (0.3 x LF + 0.7 x LF2) x 24 hrs x 356 days

Where: NC: Nos. of conductors/circuit

L: Line length (km)

NCC: Nos. of circuit

R: Conductor resistance (Ω/km)

I: Load current (A)

LF: Load factor = 0.55

(2) Iron and Copper Losses on Main Transformers

As described in the above cases shown in Figure 5.1-2, transformer loads in C GS shall be

borne by A and B GSs in the “without the project” case. Transformer losses consist of iron

(no-load) and copper (load) losses. Among these, copper loss especially increases with the

increase in load. Thus, transformer loss reduction values can be calculated for comparison

between “with the project” and “without the project” cases.

Annual transformer losses (MWh/year) can be calculated using the following formulas:

Annual transformer loss (MWh/year) = Annual iron (no load) loss + Annual copper (load) loss

Annual iron loss (MWh/year) = Iron loss (MW) x UF x 24 hrs x 365 days x TR nos.

Annual copper loss (MWh/year) = Copper loss (MW) x (load/capacity)2 x LF x 24 hrs x 365 days x TR nos.

Where: UF: Utilization factor = 1.0 (TR 1 unit), 0.95 (2 units), 0.75 (3 units), and 0.65 (4 units)


(3) Installation of Static Capacitors

In case static capacitors are to be installed in the candidate substation, annual loss reduction

value (MWh/year) by the capacitors is calculated using the following formula:

Loss Reduction (MWh/year) = (AP1 – AP2)×( 1 – (PF1 / PF2)2 ) x PF2×LF2×24 hrs×UF×365 days

Where: AP1: Apparent power (MVA) = ( (active power)2 + (reactive power)2 )1/2

AP2: Improved apparent power by capacitors (MVA)

PF1: Power factor before improvement

PF2: Improved power factor


UF: Utilization factor = 0.4

5.2 Colombo City Transmission Development (PJT-1)

5.2.1 Study on the Project Scope

With regards to the Colombo City Transmission Development Project (PJT-1), CEB had

several alternative plans considering the future system configurations, construction costs,

and construction possibilities. Through discussion with CEB in order to decide the scope of

the project, the Survey Team calculated the following three cases.


Figure 5.2-1 Calculation Cases

1) Calculation cases

Particular scope of each calculation case is as follows:

i) Option-1 (Alternative-1): almost same as the original proposal (Figure 5.2-1 (1)) - Kerawalapitiya – Port 220 kV 1,600 mm2 XLPE cable, single-circuit, 14.9 km

- Kelanitissa – Port 220 kV 1,200 mm2 XLPE cable, single-circuit, 7.2 km

- Port 220/132 kV GS with 220/132 kV 2 x 250 MVA tie-TR and 132/11 kV 4 x

31.5 MVA TR

ii) Option-1 (alternative-2): without Kerawalapitiya – Port line (Figure 5.2-1 (2)) - Kelanitissa – Port 220 kV 1,200 mm2 XLPE cable, double-circuit, 7.2 km

- Port 220/132 kV GS: same as Option-1 (Alternative-1)

iii) Option-2: 220 kV links around Colombo City (Figure 5.2-1 (3)) - Kelanitissa – Port 220 kV 1,200 mm2 XLPE cable, single-circuit, 7.2 km

- Port – Colombo M 220 kV 800 mm2 XLPE cable, single-circuit, 7.8 km

- Colombo M – Colombo K 220 kV 800 mm2 XLPE cable, single-circuit, 14.2 km

- Colombo K - Pannipitiya 220 kV 1,200 mm2 XLPE cable, single-circuit, 2.6 km

- Port: 220/11 kV GS with 220/11 kV 4 x 31.5 MVA TR

- Kelanitissa: additional 220/132 kV, 150 MVA main tie-TR

2) Calculation conditions

i) GS demands (given by CEB Transmission Planning): day peak demand in 2020

3) Calculation results

Results of the calculations are summarized in Table 5.2-1.

The following figures attached at the end of this chapter also show the results:

Figure 5.2-2 (2) Power Flow Calculation: Option-1 (Alternative-2) in 2020

Figure 5.2-2 (3) Power Flow Calculation: Option-2 in 2020

All cases satisfy voltage and system reliability criteria. As shown in Table 5.2-1,

Option-1 (Alternative-1) has the lowest percentage of transmission loss (of the whole

transmission network).

4) Cable size considerations

To decide on the cable sizes, especially for the sections between Kerawalapitiya and

Port, and between Kelanitissa and Port, the Survey Team carried out power flow

calculations with the following conditions:

- Generation capacity of Kerawalapitiya: 540 MW (+270 MW)

- Demand forecast: day peak demand in 2032 given by CEB

- System configurations: same as in 2020, but excludes outside of Colombo City

- Swing-generators (virtual-generators) are installed to 220 kV buses in Biyagama

and Kotugoda for calculation purposes.

The results of calculations considering 2032 are shown in the following figures attached

at the end of this chapter:


5 - 6



As a result of the calculations, the following cable sizes were found needed:

- Kerawalapitiya and Port section: more than XLPE 1,600 mm2

- Kerawalapitiya and Kelanitissa: more than XLPE 1,600 mm2

- Kelanitissa and Port: more than XLPE 1,200 mm2 (considering unknown 200 MW

load for ‘Ocean City’)

However, these results are obtained through many assumptions. It should be

recalculated, when the additional generators in Kerawalapitiya are realized with the

actual system configurations and substation demands.

5) Scope of the Project

Through discussions with CEB based on the above calculation results, Option-1

(Alternative-1) was selected as the scope of PJT-1. However, regarding the 220 kV

cable section between Kelanitissa and Port, 1,600 mm2 cables are to be applied since

CEB required them considering power demands in the far future.

Figure 5.2-4 shows the scope of PJT-1 with full-scale development by 2020.

Figure 5.2-4 Colombo City Transmission Development Project (Full-scale)



5 - 7

Considering electricity demand forecast and system configurations in Colombo City,

PJT-1 is divided into two phases: Phase-1 by 2015 (to be requested to JICA for 43rd

Year Loan Package), and Phase-2 by 2020 as shown in above figure.

5.2.2 Calculations for 2015 Network (Phase-1)

(1) Conditions

1) Cases: with and without Phase-1 Package

“Without the project” means substation demands in 2015 are to be applied for the

calculation, but system configuration is the same as the existing network in 2012.

2) Basic system configurations: 2015 network data provided by CEB

The Survey Team only modified the system elements to be developed under the project.

3) Electricity demand: day peak demand in 2015 provided by CEB

Electricity demands for grid substations in Colombo City with/without the project are

shown in Table 5.2-2. As for the calculation of “without the project”, the following loads

for new grid substations are assumed distributed to the existing grid substations

considering the locations:

- 100% load of Colombo L is to be distributed to Colombo F;

- 100% load of Colombo M is to be distributed to Colombo E; and

- Each 50% load of Colombo N is to be distributed to Colombo I and Colombo B,

respectively.

transformers and transmission lines for the calculation of “without the project” are not

considered.

(2) Results

Figures 5.2-5 (1) and 5.2-5 (2) (attached at the end of this chapter) show the results of the

calculations for with and without Phase-1 project, respectively. As shown in Figure 5.2-5 (1),

5.2.3 Calculations for 2020 Network (Phase-2)

(1) Conditions

1) Cases: with and without Phase-2 Package

“Without the project” means substation demands in 2020 are applied to the calculation,

but the system configuration is same as the existing network in 2012.



Electricity demands for grid substations in Colombo City for with/without the project are

shown in Table 5.2-4. As for the calculation of “without the project”, loads for new grid

substations are assumed to be distributed to the existing grid substations considering

the locations as follows:

- 100% load of Colombo K is to be distributed to Colombo A.

- Each 50% load of Colombo L is to be distributed to Colombo F and Colombo C.

- 100% load of Colombo M is to be distributed to Colombo E.

- Each 50% load of Colombo N is to be distributed to Colombo I and Colombo B.

- Each 50% load of Colombo P is to be distributed to Colombo I and Colombo B.

5.2.4 Loss Reduction Calculations

Based on the results of the power flow calculations shown in Tables 5.2-3 and 5.2-5,

transmission loss reduction values are to be estimated with the following conditions:

1) Loss reduction values between 2016 and 2019 are to be determined based on


5 - 10

compounded annual growth rate (CAGR) calculated using the following formula:

CAGR ＝（Value of year-Y／Value of year-X）＾｛1／(Y－X)｝－ 1

Where: X = 2015 and Y = 2020

2) Annual loss savings are to be calculated using the following formula;

Annual loss savings = MW loss savings x 24 hours x 365 days x (0.3 x LF + 0.7 x LF2)

Where: LF: Load Factor = 0.55

3) Annual loss savings after 2021 are assumed constant.

Table 5.2-6 shows the results of the loss reduction calculations.

5.8 Applicability of Japanese Technologies

(1) Gas-insulated Transformers

Conventional transformers with the latest technology such as ‘top-runner transformers’,

which use amorphous cores, can be regarded as the recommended Japanese technology.

However at present, such transformers with capacity of about 2 MVA scale can be produced

in general. As far as application of Japanese technology for the conventional transformers

is concerned, a special method cannot be identified for the substation facilities. However,

Japanese-made transformers are generally recommended for being highly efficient, despite

being more costly compared to others. This is attained not because of a special technique,

but due to high quality management technique adopted such as the Total Quality

Management (TQM). In this regard, the same performance can be attained in other

industrial countries such as Europe and the United States of America (USA) in terms of

production value, provided that detailed specifications prepared in advance are custom-

made to meet manufacturers’ requirements.

On the other hand, Japanese manufacturers are producing gas-insulated transformers


5 - 22

(GITs) that utilize the features of SF6 gas instead of insulation oil, and have coordinative

ability with environmental conditions. GITs are regarded for having outstanding non-

flammability characteristics, insulation effects, and safety features. Additionally, SF6 gas-

insulated switchgear (GIS) incorporates the most advanced SF6 gas application

technologies. Fully gas-insulated substations, adopting a combination of GITs and GIS,

offer extra ease for safety assurance, accident prevention, and ease of inspection and

maintenance. Concurrently, substations of this type are ideal for applications involving the

needs for prevention of environmental pollution, or compactness of installation spaces.

Advantages of GITs are as follows:

1) Non-flammability

GITs using incombustible SF6 gas as insulation and cooling medium need not require

installation of firefighting equipment in the transformer room.

2) Tank-explosion prevention

Pressure tank of GIT can withstand the pressure rise in case of internal fault.

3) Compactness

By directly coupling with GIS, substation area can be minimized.

4) Easy installation

Oil or liquid purifying process is not necessary.

5) Easy inspection and maintenance work

Only SF6 gas pressure shall be basically monitored during periodic inspection.

6) Environmental friendly

Use of SF6 gas eliminates the risk of oil leakage.

Port and Colombo L GSs are planned to be constructed very close to the sea under the

Colombo City Transmission Development (PJT-1). Under such circumstances, it is

preferred that main transformers be installed inside the substation building to prevent

unpredictable accidents of transformers caused by exposure to salt. GITs can be installed

inside the building as these have compact features.

(2) Low-loss Conductors

Japanese-made low-loss type conductors such as LL-ACSR/AC can be applied to both new

construction and reconstruction of important overhead transmission lines. Low-loss type

conductors have the same outer shape as normal ACSR conductors; however, their

aluminum cross-section area can be larger by 20%–30% as shown in Table 5.8-1, if reducing

electrical resistance is intended. These conductors contribute to transmission loss

reduction especially on heavily loaded transmission lines.

As a case study, the Survey Team studied the situation where planned 220 kV Veyangoda –

Kirindiwela (17.5 km) and Kirindiwela – Padukka (20.0 km) double-circuit transmission lines

apply LL-ACSR conductors instead of ACSR Zebra, with the following assumptions:

1) Peak loads on the line in 2015 and 2020 are taken from the results of power flow

calculations as shown in Figures 5.5-1 (1) and 5.5-2 (1), respectively. Loads in the

other years are proportionately calculated from the obtained results.

2) Power factor: 0.85

3) Load factor: 0.55

4) Conductor resistances:

- ACSR Zebra: 0.0814 Ω/km (at 63 oC)

- LL-ACSR/14AC 550 mm2: 0.0621 Ω/km (at 61 oC)

5) Formula for calculating annual loss:

Annual loss = NC x L x NCC x R x I2 x (0.3 x LF + 0.7 x LF2) x 24 hrs x 356 days

Where: NC: Nos. of conductors/circuit

L: Line length (km)

NCC: Nos. of circuit

R: Conductor resistance (Ω/km)

I: Load current (A)


5 - 24


6) Annual loss savings after 2021 are assumed as constant.

7) Average generation cost applied for the study: 13.07 LKR/kWh (to be applied for

economic analysis described in Chapter 10)

8) Conductor costs

i) Unit prices: - ACSR Zebra: JPY 620,000/km

- LL-ACSR/14AC 550 mm2: JPY 870,000/km

ii) Conductor costs: Veyangoda – Kirindiwela (17.5 km, 2-circuit, double-bundled) - ACSR Zebra: JPY 136.7 million (JPY 620,000 x 17.5 km x 12 nos. x 1.05)

- LL-ACSR: JPY 191.8 million (JPY 870,000 x 17.5 km x 12 nos. x 1.05)

- Cost gap: JPY 55.1 million

iii) Conductor costs: Kirindiwela – Padukka (20.0 km, 2-circuit, double-bundled) - ACSR Zebra: JPY 156.2 million (JPY 620,000 x 20.0 km x 12 nos. x 1.05)

- LL-ACSR: JPY 219.2 million (JPY 870,000 x 20.0 km x 12 nos. x 1.05)

- Cost gap: JPY 63.0 million

Although the initial cost of adopting LL-ACSR conductor is about 1.4 times that of ACSR

Zebra, the initial investments for both sections can be recouped within ten years and 11

years, respectively, as shown in the above table. Therefore, it is recommended to introduce

such low-loss conductors not only under the project but for planned transmission lines on

which heavy loads were forecasted.
