Executive Summary
India is and has always been a power deficit country. But since independence there has been
considerable growth in the power sector with the generation capacity being increased from 1362
MW in 1947 to 1,63,670 MW (Approx) today. The power supply position is characterized both
by shortages in meeting the demand during the peak hours and by shortages in the overall energy
supply. The peaking shortage is much more in every region and it is about 12% on all India basis.
The energy shortages on regional basis are varying in magnitude and overall shortage on all India
basis is about 7%.
But the demand is not uniform everywhere. Moreover there are regions where there is full-
fledged generation but very less consumption. For example, the state of Chhattisgarh has a lot of
generation capacity and at the same time the consumption is very less making it a power surplus
state. The country is divided into five different regions with each region having its own
peculiarity. There are various surplus and deficit regions in the country due to which the concept
of power trading comes into the picture. This is because of seasonal surplus in one state
coinciding with a deficit period in another. It helps a great deal in reducing the demand-supply
gap.
The implementation of the ABT mechanism has brought about considerable improvement in the
grid discipline with the UI charges acting as a penalty for a deviation from the schedule. It also
acts as revenue for the generators when there is under drawl by the buyers or an over injection by
the generating station. The UI charges are payable by the generating stations if there is over
drawl by the buyer/beneficiary or an under injection by the generating station. This way the
efficiency of the grid is ascertained.
The types of trading are categorized under long term, medium term or short term. The trading
through the exchanges are considered to be short term trading. Bilateral and banking agreements
also come under short term trading. Presently there are two power exchanges viz. IEX and PXI
operating in the country.
This report also highlights the various regulations affecting the short-term trading of power.
These are the regulations related to the Open Access, the procedures of scheduling various
4 | P a g e
transactions etc. The Indian Power sector is highly regulated by the CERC and so it is imperative
that one should understand the various regulations related to it.
The objective of the study is to shed some light on the emerging power trading mechanism with
special reference to the short term power trading which is done through bilateral agreements,
banking agreements and the power exchanges.

Chapter 1: Introduction
1.1. Overview of power sector
Accessibility, Availability and Acceptability are the three main objectives of the power sector. In
order to achieve these objectives the power sector has to be reliable both in terms of quality and
efficiency. The growth in this sector has been immense and the Indian economy continues to
surge ahead. The demand for power is never ending and in fact the demand has been increasing
over the years. It has become a growing concern for the people in the power sector to meet the
demands of the public.
Existing generation suffers from several recurrent problems. The international standards are way
too high as far as the efficiency and the availability of the coal power plants are concerned. Low
heat content and high-ash unwashed coal is used by the majority of the power plants. This results
in a high number of airborne pollutants per unit of power produced. Thereby polluting the
environment and increasing carbon emissions. In the context of fast-growing demand, large T&D
losses and poor pooling of loads at the national level exacerbate the lack of generating capacity.
India being the 11th largest manufacturers of energy worldwide makes its presence felt in the
energy sector with respect to its manufacturing strength and in terms of its usage. It is also the
worlds’ 6th largest consumers of energy. Although India has an extensive yearly energy output it
is a regular importer of energy because of the disparities in consumption.
Power is one of the few commodities which have always been in short supply in India. This is
one of the main reasons why India remains always hungry for power both in terms of peak and
off-peak power demand. There are various sources of power generation in India viz. thermal
power, hydropower or hydroelectricity, solar power, biogas energy, wind power etc. The
distribution of the power generated is undertaken by various distribution companies at its
respective state levels.

1.2. Global Overview
Energy plays a vital role in the day to day activities of our lives. It plays a tremendous role in
supporting our convenience and living standards. Energy consumption is normally high in the
industrialized countries as compared to the developing countries. The United States of America
consumes around 26% of the world energy in total. The average annual growth rate of the world
electricity generation was 3.7% from 1971 to 2004 which was greater than the total primary
energy supply which grew at 2.1%. This increase was mainly because of more electrical
appliances, development of electrical heating in several developed countries and rural
electrification programmes in developing countries.
There is a fierce competition in the global energy markets due to de-regulation. Now electricity is
being produced a lower cost with many countries trying to reduce the impact power generation
has on the environment. 30% of the world’s energy is used by the developing countries
collectively but it is expected to rise to 95% with the projected population and economic growth
in those markets. Overall global consumption is expected to rise 50 % from 2005 to 2030.
The world net electricity generation is projected to rise from 17.3 trillion kilowatt hours in 2005
to 24.4 trillion kilowatt hours in 2015 and 33.3 kilowatt hours in 2030. The strongest growth in
demand is shown by the non OECD countries due to the expansion in their power grid for
supporting and maintaining the robust economic growth. There is an average increase of 4% per
year from 2005-2030 in the total electricity generation in the non OECD countries whereas in the
OECD countries the average increase is 1.3% per year for the electricity generation.
The coal and natural gas account for the largest increment for the projection period 2005-2030 as
far as the fuel component of electricity is concerned. The coal based generation appears to be
more economical considering the high prices of the oil and natural gas. But the coal power plants
can get restrictions from the various international agreements for cutting down of the greenhouse
gases. The electricity sector as such offers the most cost effective opportunities for reducing CO 2
emissions in many countries and its proving worth in real times also. A series of achievements
have been made when clean coal technology is considered. They have clinically tested and
proven, implementing these new technologies would not require expensive and large-scale
12 | P a g e
changes in the power distribution infrastructure or in electricity-using equipment. An alternative
for reducing these emissions is to improve the efficiency of the equipment that uses electricity.
Electricity generation from nuclear power is projected to increase from about 2.6 trillion
Kilowatt hours in 2005 to 3.8 trillion Kilowatt hours in 2030 as there are rising concerns over
rising fuel prices for oil and natural gas, energy security and reduction of greenhouse gas
emission agreements support the development of new nuclear generation plants and older plants
have also citied high capacity utilization rates and there is also considerable uncertainty
associated with nuclear power plants. The various issues that slow down the development or
expansion of nuclear power plants include plant safety, radio-active waste disposal, wrong use of
the nuclear technology in making weapons of mass destruction, concerns of attacks because of
the increasing number of terrorist attacks all over the world and high capital & maintenance cost.
The IEO (2008) projection on nuclear electricity generation in 2025 is 31% higher than the IEO
(2003) projection that was pollution friendly five years ago.
In the IEO (2008) projection, the worlds installed capacity grows from 374 Giga watts in 2005 to
498 Giga watts in 2030. The decline in nuclear capacity projected only for OECD Europe, where
as countries like Germany and Belgium are planning to phase out their existing nuclear power
plants. There is strong growth projected in the Non-OECD Asian countries, where 68 Giga watts
of additional installed capacity is projected for Asia between 2005-2030, 45 Giga watts in China
and 17 Giga watts in India and outside Asia, the installed capacity is high in Russia and is
expected to have an additional 18 Giga watts.
High Oil and Natural Gas price pushing demand for generation RES and it’s also attractive for
environmental reason’s because of its pollution free nature. Worldwide consumption of
electricity from hydro power plants and other renewable sources have increased by 2.1% in the
IEO(2008) projections from 35 quadrillion BTU in 2005 to 59 quadrillion BTU in 2030
The per capita consumption of India is far behind when compared to the world average and very
less when compared to other countries. So there is a need to improve it and its only possible
through successfully implementing various initiatives taken by the government.
Though India has achieved many milestones in generation still the there is a wide gap between
demand and supply of power. This is the most important issue we must to be concerned with.

1.3. Indian Power sector reforms
a) Electricity Act, 2003
After the implementation of the Electricity Act 2003, a new paradigm has been created for the
development of the power sector in the country. The monopoly created through the Electricity
(Supply) Act, 1948 of the State Electricity Boards has been abolished with the implementation of
this Act. It has created a new competitive framework for the development of the power sector in
the country with special focus on the interests of the consumers by independent Regulatory
Commissions. Almost all the barriers in the entire chain of the electricity supply business are
reduced or eliminated after the implementation of this Act.
It marks the culmination of the process beginning in the mid nineties of the states enacting their
own Reform Acts and the enactment of the Electricity Regulatory Commission Act of 1998
which brought into place the Central Electricity Regulatory Commission and authorized the
states to create SERC if they wished to do so.
The key features of this Act are discussed below:
To establish independent Regulatory Commissions in the States as well as the Centre
To free up thermal generation from the requirement of any prior clearances
Offering full freedom for setting up of captive power plants including group captive
power plants
To create an all India market and also allow Open Access in transmission
To encourage private investment in transmission through licensing by regulatory
commissions. There is also the full freedom for building dedicated transmission lines
Open access in distribution to be introduced in phases with consumers above 1 MW
getting the right of Open Access, latest by January 2009
To enable the provision for more than one distribution licensee in the same area.
Prescription of performance standards for distribution licensees and its enforcement by
Regulatory Commissions.
To establish a multi-year tariff framework for performance based regulation to incentivize
efficiency gains.
14| P a g e
To bid generation tariffs competitively so that it is accepted by the regulatory
commissions. The power purchase costs of the customers availing open access is to be
determined by the market.
An Appellate Tribunal is maintained for the quick disposal of appeals against decisions
of the State Regulatory Commissions or the CERC.
c) National Electricity Policy
The features of the policy are discussed below:
To provide access to Electricity and make it available for all households in the next five
years.
To meet the power demand fully by 2012 and to overcome the energy and peaking
shortages and also spinning reserve of 5% to be available at the national level.
To supply reliable and better quality power with specified standards at reasonable rates.
To increase the per capita availability of electricity to over 1000 units by 2012.
Minimum lifeline consumption of 1 unit/ household/ day as a merit good by year 2012.
To develop the hydro potential of the country fully.
Economics based choice of fuel for thermal generation and supply of electricity.
To develop the national grid of the country.
To extend the Availability Based Tariff (ABT) to the state level.
To introduce all India transmission tariff sensitive to distance and direction by the CERC.
d)Tariff Policy
The salient features of the National Tariff Policy are given below:
To accept the tariff of generation and transmission projects in private sector determined
through competitive bidding by the Regulatory Commission.
To reduce the amount of cross subsidy to around 20% of average tariff in the next five
years.
15| P a g e
To facilitate the open access in distribution and formulate clear policies on cross subsidy
surcharge.
The transmission tariff to be sensitive to distance and direction.
To implement the performance standards strictly.
To introduce time-bound multi-year tariff.
16 | P a g e
Chapter 3: The concept of trading
3.1. BACKGROUND: Power trading inherently means a transaction where the price of power
is negotiable and options exist about whom to trade with and for what quantum. In India, power
trading is in an evolving stage and the volumes of exchange are not huge. All ultimate
consumers of electricity are largely served by their respective State Electricity Boards or their
successor entities, Power Departments, private licensees etc. and their relationship is primarily
that of captive customers versus monopoly suppliers. In India, the generators of electricity like
Central Generating Stations (CGSs), Independent Power Producers (IPPs) and State Electricity
Boards (SEBs) have all their capacities tied up. Each SEB has an allocated share in central
sector/ jointly owned projects and is expected to draw its share without much say about the
price. In other words, the suppliers of electricity have little choice about whom to sell the power
and the buyers have no choice about whom to purchase their power from.
The pricing used to be fixed by the Central and State Governments. However, it is now done by
the Regulatory Commissions at the Centre and also in the States wherever they are already
functional. Power generation/transmission is highly capital intensive and the Fixed Charge
component makes up a major part of tariff. The power demand in India is basically seasonal and
weather sensitive with India being a predominantly agrarian economy. There also exists a
substantial difference in the demand of power during different hours of the day with variations
during peak hours and off peak hours. Further, the geographical spread of India is very large and
different parts of the country face different types of climate and different types of loads.
States like Karnataka and Andhra Pradesh experience low power demand during the rainy
seasons and high in Delhi and Punjab. Whereas many of the States face high demand during
evening peak hours, cities like Mumbai face high demand during office hours. There is a
significant surplus in the Eastern Region round the clock, and even normally power deficit
states with very low agricultural loads like Delhi have surpluses at night. Such situations
indicate enough opportunities for trading of power. This would improve utilization of existing
capacities and reduce the average cost of power to power utilities and consumers.
17 | P a g e
In view of high fixed charges, average tariff becomes sensitive to PLF. Trading of power from
surplus State Utilities to deficit ones, through marginal investment in removing grid constraints,
could help in deferring or reducing investment for additional generation capacity, in increasing
PLF and reducing average cost of energy. Over and above this, the Scheduled exchange of
power will increase and un-scheduled exchange will reduce bringing in grid discipline, a
familiar problem.
According to the Electricity Act 2003, trading is defined as “purchase of electricity for sale
thereof”. Trading is recognized as a distinct activity.
3.2. Evolution of the Indian Power market
The Indian power market has evolved over the years. The installed capacity for generation was
1362 MW in 1947 and the present capacity for generation in India is 1,63,670 MW. The actual
power supply position in 2009-10 according to the Ministry of Power are discussed below-
The energy requirement is 8,30,594 MW
The energy availability is 7,46,644 MU
The energy shortage is 83,950 MU (10.1%)
The peak demand is 1,19,166 MW
The peak met is 1,04,009 MW
The peak deficit is 15,157 MW (12.7%)
The peak power demand is growing at 7.85% (compounded annual growth rate) and energy
demand at 6%.
17 | P a g e
3.3. Indian Power supply scenario
Fig 2. Energy Availability & Requirement
From the above diagram we can see that there is a considerable gap between the energy available
and the energy which is required. The total energy availability is 739 BU whereas the total
requirement of energy is 786 BU.
,
Fig 3. Peak Demand in GW
18 | P a g e
The above figure highlights the actual demand prevailing in the country and the demand that is
being met. The actual demand in GW is 108 GW and the demand met is only 90 GW.
The installed capacity of the various regions of India is shown with the help of the following
table with the ownership sectors as well as the mode wise breakup viz. thermal, nuclear, hydro,
and renewable energy sources.
Table 1. All India installed capacity of power generation
19 | P a g e
Fig 4. Regional capacity of generation
The figures shown in the above diagram have been revised in the table shown before with the
region-wise installed capacity. The total installed capacity of the northern region including all the
generation modes i.e. thermal, nuclear, hydro and renewable sources is around 38723 MW with
the major share of the thermal power plants being 22351 MW. Nuclear has a very small share of
1180 MW whereas hydro still has potential in the northern region with a generation capacity of
13425 MW. The renewable energy sources share is around 1766 MW. The Western region has a
total installed capacity of around 45965 MW with the major share being of the thermal power
plants again. The total installed capacity of the thermal power plants in the western region is
around 32653 MW, the nuclear capacity being 1840 MW, 7448 MW for the hydro plants and
around 4023 MW from the renewable sources. The total installed capacity of the Southern
Region is 40430 MW. The total thermal capacity in the Southern Region 21328 MW, nuclear is
around 1100 MW, hydro capacity is 10954 MW and there is a considerable share of the
renewable sources with 7047 MW. The total installed capacity in the eastern Region is around
20814 MW with 16653 MW thermal capacity, 3933 MW hydro capacity, 227 MW renewable
sources capacity with no generation capacity through nuclear. The total capacity of the North-
20 | P a g e
Eastern Region is around 2255 MW with the major generation capacity being of hydro with 1116
MW, thermal being the next with 968 MW and also renewable sources contributing 171 MW. It
has no generation capacity through nuclear. The total installed capacity of the islands is taken
into consideration separately, the capacity being 76 MW with the major generation through
thermal stations. Combining all the regions of the country the total installed capacity of India
goes to around 148265 MW with the major share being that of thermal with 94025 MW 4120
MW of nuclear capacity, 36877 MW of hydro capacity and 13242 MW of renewable sources
capacity.

3.4. Why trading?
Fig 5. Peculiarities of regional grids in India
India is divided into five different grids and every grid has its own peculiarity. Like, the northern
grid is a deficit region which has highly weather sensitive load. It has adverse weather conditions
with fog and dust storms. In the North eastern region the load is very low but it has high hydro
potential. In the eastern region there is low load but the reserves of coal is very high. It has pit
head base load plants. In the western region the load is basically industrial load and agricultural
load. In the southern region the load is very high and it is basically dependent on hydro potential.
Here, 40% of the load is agricultural load.
22 | P a g e
Fig 6. Typical seasonal load curves for the Northern region
In the northern region the load during the summer seasons remains near the 22000 MW mark in
the wee hours of the morning. It reduces a little bit during the daytime but it again shoots up at
the evening time to around 24000 MW. In the winter season during midnight the load is around
19500 MW. It increases in the morning time and goes to around 22000 MW and again reduces
after 11 am. The main peak is reached during the evening time when the demand goes to around
23000 MW.

Fig 7. Typical seasonal load curves for the southern region
During the summer time the load is almost same throughout the day with the load increasing a
little bit in the evening time. It fluctuates round the 20000 MW mark but during the evening peak
it goes to around 23000 MW mark. The winter time witnesses a drastic change in the load curve
with the load increasing mostly from 7 o’clock in the morning and reaches the peak at the
evening time. At this time the load is around 21000 MW. During the monsoons the load falls
further down with the evening peak around 18500 MW.
24 | P a g e
There is always the existence of shortages in meeting the peak as well as the overall demand.
Although there is an overall shortage, the inherent density in demand of various states and
regions in the country results in periods of seasonal surplus in one state or region coinciding with
periods of deficit in another region. This coexistence of overall shortages with complementary
geographical and temporal surplus-deficits provides substantial opportunities to improve the
economic efficiency and the security of supply through trading of power both within as well as
across regions. With the trading of power across the regions it has been possible to reduce the
demand and supply gap in various states of India.
There is also the need for the availability of adequate transmission capacity and inter regional
links for transfer of power from a surplus to a deficit entity and support. This way the full
benefits of trading can be realized.
Trading is also required for developing a fully fledged, efficient and competitive market
mechanism for power trading and also to facilitate the development of generation projects
including through private investment, both resulting in reliable, economic and quality power in
the long term.
It also helps in developing a power market for optimum utilization of energy. Optimum
utilization of existing resources is possible with the help of power trading.
It also aims to catalyze the development of power projects particularly environment friendly
hydro projects.
It also promotes the exchange of power with the neighboring countries.
25 | P a g e
3.5. Power trading current scenario
Almost 97% of the supplies are locked up in the long term PPAs i.e the Power purchase
agreements.
The remaining 3% is constituted by the short term trading
Trading is always done between a surplus and a deficit region
Trading plays a vital role in the optimization of resources and also meeting the short term
peak demand
The trading basically takes place between two regions i.e inter-regional
The introduction of the open access regulations have facilitated the trading of power in an
orderly manner
All the energy agreements and transmission clearance should be arranged separately
The charges for open access are reasonable and easy to apply
The suppliers call for various bids from the buyers/traders
There is a tough competition between the traders to win the supply bids
If the buyer has entered into some contract with a trader for buying power he has no other
option but to buy from the trader having the supply contract.
There is a huge gap between the demand and the supply of power and due to this reason
the suppliers dominate.
The price of traded electricity keeps on fluctuating depending on various factors.
26 | P a g e
Chapter 4: Availability Based Tariff
It is a generation tariff based on the premise of two part tariff structure (i.e. a fixed component
and a variable component) with the fixed component linked with the availability and the variable
component linked to the schedule generation. Availability based tariff can be viewed as a
commercial mechanism for improving the grid discipline and the frequency regime. It is a pricing
mechanism for electric power on the basis of frequency. It can also be considered as a
commercial mechanism for the Merit Order Operations. The ABT falls under electric market
mechanisms to charge and regulate power to achieve both short and long term network stability
as well as the incentives and the disincentives to market participants against deviations in
committed supplies as the case may be. ABT provides an efficient default market for trading and
encourages trading arrangements.
4.1. Components
Capacity charges: These are the charges payable by the beneficiary based on the
capacity allocated. They are also called the fixed charges. The payment of the capacity
charges based on the capacity available rather than the energy generated helps in the
avoidance of unwanted generation. It depends on the fixed component of generator like
Interest on loan, Return on Equity and Historical Cost. It is calculated based on the day
ahead availability declaration by generator.
Energy charges: These are the charges based on the scheduled energy. It depends on the
fuel cost.
Unscheduled Interchange (UI) charges: These are the charges levied for the deviation
from the schedules. The UI rate is considered as the default rate of trading. It is basically
dependent on the frequency which is an indicator of the demand and supply gap. It also
depends on the efficiency of the market. It encourages trading arrangements to hedge risk
of UI charges. In the decentralized scheduling system UI rate encourages the backing
down of the generation plants in the decreasing order of the variable cost given in the
Merit Order as the frequency goes up and vice versa when the frequency goes down.
27| P a g e
4.2. How do the beneficiaries share the payment?
Capacity Charges: It is the recovery of fixed charges based on the availability.
CAPACITY CHARGES = C.C. RATE * AVAILABILITY IN MW *
BENEFICIARY’S % ENTITLEMENT
Each beneficiary shall pay the capacity charges in proportion to its allocated percentage share in
the total capacity of the station as per the entitlement issued by State Load Dispatch Centre to the
respective generating station.
Energy Charges: It is the recovery of variable charges based on schedule generation in a time
block at a rate as fixed by the regulatory commission for the station and according to bilateral
agreement made by generating station and beneficiary.
ENERGY CHARGES = (BASE VC RATE + FPA) * BENEFICIARY’S SG
Each beneficiary shall pay the variable charges to respective generating station in proportion to
its drawl schedule based on the requisition of each beneficiary. The drawl scheduled will be
issued by State Load Dispatch Centre.
Unscheduled Interchange charges: It is the variation of actual generation with respect to
scheduled generation.
Unscheduled Interchange = Actual Generation – Scheduled Generation.
U.I. Charges = {Actual Energy Interchange in a time block -
Scheduled Interchange for the time block }
* Unscheduled Interchange rate for the time block.
Depending upon whether a utility is supporting or adversely affecting the Grid, UI Charges will
be receivable or payable which in turn called as a reward or penalty for the proactive action of
generator. Accordingly receivables and payables of each UI member will be calculated on
weekly basis.
28 | P a g e
4.3. How does the mechanism work?
1. Generator declared the day ahead capability in the 96 time blocks for the possible
generation foresee and to be submit to SLDC.
2. Based on the allocation, declaration shall be break up for the respective beneficiary and
Entitlement will be issued to each beneficiary for all generating stations by SLDC.
3. All beneficiaries shall submit their requisition to SLDC for each generator in 96 time
block as per the demand forecast by them. It should not exceed their entitlement.
4. SLDC will compile the requisition received from each beneficiary and finalize the total
drawl schedule for each generator and prepared dispatch schedule.
5. Similarly, drawl schedule for each beneficiary shall be prepared as per their requisition
and bilateral.
6. Beneficiary shall also requisite for bilateral transaction through open access by reserving
corridor in advance to meet difference between demand forecast and entitlement . Same
shall be incorporated in the drawl schedule.
4.4. Why Availability Based Tariff is necessary?
1. Large deviations in frequency from the rated frequency 50.00 Hz reduced and grid
disciplined maintained due to ABT. The earlier mechanism does not provide any such
mechanism, incentive for optimum generation during peak hours and backing down
during low demand.
2. Each beneficiary takes part in ABT and they shall also manage their load by curtailing at
low frequency and adding demand during high frequency. At low frequency, beneficiary
may receive through UI mechanism. At high frequency, beneficiary may satisfy consumer
demand at low price through UI mechanism.
3. The generators optimize their generation at low frequency and receive payment through
UI mechanism and reduced generation at high frequency and saves fuel.
29| P a g e
4. Grid discipline maintained and system operation becomes safer.

Chapter 5: Types of trading
5.1. Long Term and Medium Term
Long term and Medium term procurement of power is done through PPA’s where in Long term
PPA refers to agreements signed in for more than 7 years for the procurement of power and
medium term refers to agreements where the duration or validity of agreement is more than 1
year and not exceeding 7 years. These agreements are the central or core to the health of the
power sector, to be precise in those countries that have opted for single-buyer market structure.
The capital cost of the electricity generating plants often constitute a large share of the final cost
of power also referred to as the pass through mechanism i.e. at the end of the day it’s the buyer at
the end of the chain who has to bear the cost. In the case of thermal generation units fueled by
imported oil have faced problems due to the price fluctuation of the fuel because these fuels are
traded in international markets which are highly volatile and at certain situations like a war or
sudden demand shoot-up can lead to prices of these products to escalate to new heights there by
burdening the end user i.e. the consumers.
In cases where the risk allocation and sale price in PPA is one sided, then the bulk supply price
of power that results from the PPA may turn out to be very high and economically unstable. In
our country PPA’s are mostly entered between state/central/private generators as sellers and state
or central government undertaking wherein they are the purchaser, since the power sector of
India is highly regulated in most cases the sale price of the power was fixed by the governments
and on a long run it burdens the generation companies in private sector to supply the agreed
quantum at a fixed price due to the high construction cost incurred because the gestation period
of power plants can go into years if faced with unforeseen situation like policy changes caused
by new government at power i.e. political factors, cost of construction increasing due to
variations in global markets and increase in fuel cost due to volatility in global markets, these
issues can lead to losses borne by the seller if he sticks on with the agreement(private players)
whereas public sector generators losses would be borne by their respective states or the central
government.
The Enron fiasco can be classified under the above mentioned situation. Enron was world energy
giant they got permission to set up a thermal plant in Ratnagiri district of Maharashtra to meet
31 | P a g e
the load demand of the state but once the plant was completed they could not stick with the
original agreement because their estimated cost of construction of the plant had gone up and the
price of fuel used for generation had also risen, putting the company a financially unsustainable
position if they had followed the agreement for selling power at the agreed prices. Now the plant
was taken over by GAIL and NTPC and it is floating its way out of losses.
PPA’s are a guarantee for the generating company to get back their cost fixed cost i.e. cost
involved in development and construction of the plant and also a guarantee for the fuel
agreement between the generator and the seller of the fuel from a seller’s perspective. From
buyers perspective it’s a guarantee to meet his load demand in the future once the plant is
operational and dedicated to commercial development. Central Electricity Authority (CEA) a
Statutory organization under the Ministry of Power, India con ducts an Electric Power Survey
(EPS) every 5 years to work out the load demand for all the states in the country based on
various factors, the latest survey was the 17th and its report’s were published in the year 2007.
With reference to the survey results, respective state governments get into Long-term PPA’s to
secure their load demand.
According to the tariff policy issued by Ministry of Power, the power purchase agreements
should ensure adequate and bankable security arrangements to the generating companies and in
case of persisting default from the purchaser in the form of letter of credit(LC), escrow of cash
flows etc then the generating company can sell of the generated power to other sellers.
5.2. Short term
Short Term trading is the trading done through bilateral agreements, banking agreements and
power exchanges. The short term trading accounts for about 3% of the total electricity
generation. It mainly helps in the reduction of the demand and supply gap by trading of power
among the surplus and the deficit regions. It is basically done on day-ahead basis but there are
also bilateral agreements which can be for a month. The bilateral agreements are useful for
buying or selling of power at a future date regardless of what the prevailing prices are at that
32 | P a g e
time. They are merely between two parties i.e. a buyer and a seller and no other party is involved.
Banking agreements are also a kind of short term trading which is done between two parties but
it is non monetary. Here only a fixed amount of power is exchanged between the parties with a
promise to return it back at a particular date in the future. There can be various other conditions
in the agreement related to the quantity of power such as the quantity to be returned back may be
more than that was taken in the initial stage according to the conditions given by the lending
party.
Power exchange is the heart of short term trading. With the evolution of the power exchanges the
power scenario has drastically changed. They are a medium through which surplus regions can
sell power to the deficit regions. This has also increased the efficiency of the power system as a
whole as the power deficit states can easily quote the quantity needed to buy and vice versa for
the surplus states. They do not have to look for buyers/sellers as the case may be and consume a
lot of time. This has not only helped in increasing the efficiency but also in reducing the demand-
supply gap of power which is remarkable in the Indian context. The details about short term
trading are discussed in the following chapters.
33 | P a g e
Chapter 6: Types of Short term trading
Short term trading includes the trading through:
Bilateral Agreements
Banking Agreements
Power exchanges
6.2. Bilateral Agreements
An agreement in which each of the parties involved in the contract makes a promise to each other
to buy/sell power on a particular date in the future. Bilateral Agreements are of two types viz.
Bilateral Import and Bilateral Export. These can be done on the basis of real time, day ahead and
on firm basis. The real time agreements are done on the same day, sometimes 11/2 hour before
the scheduling of power. This is because it takes only 11/2 hour to get the power scheduled
depending on the availability of the transmission capacity. The agreements on a day ahead basis
are done one day in advance. Whereas the agreements on a firm basis are those for which the
open access have been applied in advance.
In the case of a Bilateral export the consent has to be taken from the respective SLDC for the
sale/purchase of power. The quantum available for export is given to the traders and the traders
give the offers to the buyers and the sellers. The rates of the traded power are decided on
mutually agreed price. In this whole process the trader acts as a communicator between the
buyers and the sellers. The whole process is done verbally.
After this the trader sends the letter of intent (LOI) to both the buyer and the seller. After the
signing of the agreement by both the parties as per the agreed quantum and price, the open access
application is forwarded to both the buyer and the seller. The consent of both the parties is
required for the agreement to take place. The consent is then forwarded to the respective SLDC
for their approval. The approval from the respective SLDCs is followed by the open access
applications being forwarded to the traders by both the buyer and the seller. After this the trader
applies for the open access to the respective RLDCs. All the transactions are done through Fax. If
the transmission capacity is available in the network the power gets scheduled for the respective
time slots.
34 | P a g e
The decisions as to at what rate the power should be bought or sold are mainly taken on the basis
of the prevailing UI rates. It also depends on the weather conditions.
The trader gets a maximum of 4 paise per unit. The wheeling charges are to be borne by the
buyer from the point of delivery by the seller.
An Example:
Power purchased from MSEB by NDPL the delivery point being the MSEB periphery. Then the
transmission charges which have to be paid will be through the link
MSEB – WR – NR – DTL
The charges to be paid are 5 + 5 + 3.5 = 13.50 paise/unit
Operating charges: Rs.2000 to be paid to the respective RLDC
Scheduling charges: Rupees 5000 to the respective SLDC
All the transmission charges, operating charges, scheduling charges are to be borne by the buyer
after the delivery point.
6.2. Banking Agreements
An agreement between two parties in which either of the parties agree to supply the power to the
other party for a specified period of time and as per the agreement the power is returned back by
the consuming party in the specified time period. These kind of agreements are also of two types
viz. day ahead banking and firm based banking.
For example:
If NDPL enters into a banking agreement with Rajasthan, the power supplied by NDPL in the
month of November, December, January (say 200 MUs) will be returned by Rajasthan in the
months of April, May and June.
Banking agreements are mainly useful when there is a seasonal disparity in the availability of
power. Now, Delhi is a power surplus State in the winter season and the winter season demand is
less as compared to the summer season. There is no profit in the case of an under drawl because
35 | P a g e
the average UI rate is too less. In the summer season there is a huge shortfall to the tune of 250-
300 MW and nobody is willing to sell the power even at the rate of 10 Rupees/unit. The
frequency of the grid is worst during the summer season. The banking agreements are also useful
to keep the average power purchase cost down.
6.3. Power exchanges
Power exchange is a platform available for the purchase and sale of power in addition to the
bilateral agreements. It operates on a day-ahead basis, functions on all days including bank
holidays and Sundays.
Facts on Power Exchanges
Competitive wholesale spot trading arrangement that facilitate the selling and buying of
electricity.
It is an organized market that facilitates trade in standardized hourly and multi-hourly
contracts.
Develop marginal cost for its energy transaction – A price index
Power exchanges are ‘energy only market’ since they do not take into account any
technical aspects like transmission constraints or capacity payments.
Bids on an exchange only contain quantity and prices for a particular period.
An exchange is absolutely neutral towards the market because its
Rules apply to both sides of the transaction.
Power exchange is a voluntary market place
Competition in an electricity power exchange’s spot market occurs by generators,
distributors, traders and large consumers submitting bids for buying and selling
electricity.
Each sale bid specifies the quantity and the minimum price at which they are willing to
supply the energy.
Conversely, each buy bid specifies the desired quantity and the maximum price at which
they are willing to buy the energy.
36| P a g e
The power exchange matches supply and demand along with publishing a market-
clearing price.
Power exchanges have trading rules, which cover the setting of prices, delivery, clearing,
type of product, timing etc.
The role of a power exchange is to facilitate the trade of short-term products.
The key features of an exchange are discussed below-
Nation-wide, electronic Exchange for trading of Power

. Fig 9. Market Clearing Price graph
Market Clearing Price is the price which is found out in the exchanges by taking the total number
of buyers and the total number of sellers in a particular time slot. First, the total number of
buyers is taken into consideration i.e. the demand in the market, and the graph is drawn. After
that the graph for the total number of seller i.e. the supply is drawn. The intersection point of the
two graphs is called the market clearing price for that particular time slot. The area lying to the
left hand side of the market clearing price is the market clearing volume or the traded volume in
the market.

Chapter 7: Indian power exchanges and their mechanisms
7.1. INDIAN ENERGY EXCHANGE
Section 66 of the Electricity Act 2003 made it mandatory for the development of Power markets
by appropriate commissions through enabling regulations. The Central Electricity Regulatory
Commission (CERC) issued guidelines for grant of permission for setting up and operation of
power exchange on 6th February 2007. This was done within an overall regulatory framework.
The Indian Energy Exchange (IEX), promoted by the Financial Technologies (India) Ltd. and
PTC India Ltd. is India’s first power exchange with an automated and online trading electricity
platform.
IEX being a demutualised exchange will enable efficient price discovery and price risk
management in the electricity market. The exchange has been developed as a market based
institution for providing price discovery and price risk management to the electricity generators,
distribution licensees, electricity traders, consumers and other stakeholders.
The broad features of the exchange are given below:
Nationwide, online and electronic platform
Voluntary participation
Neutral, unbiased and transparent
Offers day-ahead market
Exchange time line consistent with time line of load dispatch centers
The activities of the power exchanges will be carried put in accordance with the Central
Electricity Regulatory Commission (Open Access inter-state transmission) Regulations,
2008 dated 25.02.2008 as revised from time to time and the bye-laws, rules and
business rules of the exchange.
44 | P a g e
MECHANISM used in IEX
A double sided closed auction mechanism is used in the current day ahead trading market. Both
the buyers and sellers shall pay/receive uniform price.
A separate interpolation auction procedure is used for the 24 hourly periods. The closed auction
method is a reliable method allowing both buy and sell bids to be submitted at the same time
without disclosing the identity of the buyer or the seller, price and quantity of bids. Both the
parties are under pressure to give in their best bids and true competition is ensured. It also
ensures that all parties receive the uniform price which is same or better than their price bids.
Market liquidity is also ensured by concentrating orders on each hourly market.
The transmission charges and losses are expected to be borne by the buyers and sellers in their
regional transmission system till the periphery of the transmission system. The operating charges
are also to be paid and a nominal transaction fee of 1 paise / kwh is also required to be paid.
After market closure, IEX calculates the MCP i.e. the Market Clearing Price on the basis of the
total number of buyers and the total number of sellers in the market and also the MCV i.e the
Market Clearing Volume on hourly basis and will forward the regional corridor required between
the inter regional links as well as the region wise traded quantity.
IEX is mainly responsible for the financial aspect of the transactions, NLDC/RLDC/SLDCs
ensure the electricity supplies and withdrawals correspond to the commitments contracted on the
exchange. It becomes obligatory for the participants to deliver or take delivery of the
corresponding net volume of electricity in the regional grid.
IEX validated transactions are deemed to be physically delivered. If the delivery commitment is
not fulfilled it becomes a liability for the participant to pay unscheduled interchange charges as
stipulated by the CERC to the RLDCs UI pool account or to SLDCs pool depending upon
whether it is a regional entity, embedded customer or else.

7.2. Power Exchange India Limited
Power Exchange India Limited (PXIL) is a fully electronic, nation-wide exchange for trading
of electricity. It has been promoted by two of India's leading Exchanges, National Stock
Exchange of India Ltd (NSE) & National Commodities & Derivatives Exchange Ltd (NCDEX).
Power Finance Corporation, Gujarat Urja Vikas Nigam, JSW Energy, GMR Energy, Jindal Steel
& Power have taken equity stakes in this venture.
NSE is the largest stock Exchange in India and amongst the top 4 Stock Exchanges in the world
in terms of number of transactions. The standards set by NSE in terms of market practices,
products, technology & service standards have become industry benchmarks and are being
replicated by other market participants. NCDEX is the only commodity exchange in the country
promoted by national level institutions. The institutional promoters and shareholders of NCDEX
are prominent players in their respective fields and bring with them institutional building
experience, trust, nationwide reach, technology and risk management skills.
PXIL, like its promoters, will not just be building a Power Exchange, but would also be seeking
to play a thought leadership role in shaping India power markets in the years to come. PXIL aims
to provide transparent and fair price discovery mechanism which can signal massive potential
investments into the Indian Power Sector.
The initial products offered for trading are electricity contracts offered on a day-ahead basis with
voluntary participation. New products will be introduced after taking feedback from the market
& obtaining approval from CERC. PXIL has an independent Board of Directors and
professionals who manage the day-to-day operations. The Company is run on commercial
principles as an individual business entity, separated from the business of its shareholders.
PXIL received regulatory approval from Central Electricity Regulatory Authority (CERC) on
30th September 2008 to begin operations. After receiving the final nod from the National Load
Despatch Centre, the apex body of the country grid operator, PXIL has successfully started its
operations on 22nd October 2008.
46 | P a g e
The last seven months have provided the Power Exchange India limited with the demand and
requirements of the Indian power market. Power Exchange India Limited has recently joined the
Association of Power exchanges which is a world body of the power exchange. It plays a key
role I the development and knowledge sharing of the best in class market practices. The members
of the Association of Power Exchanges are – Nordpool, EEX, PJM, NEMMCO, OMEL etc. it is
a major step in the development of the Indian power market.
Power exchange India Limited has proposed the idea for the development of intra state electricity
markets such that the buyers and sellers including the captives and the industrial consumers can
deal with one another in the exchange. The electricity surplus and the demand that is not met in
this intra state market would be cascaded such that it can be sold in the national market through
the power exchange on the next day. These intra state markets would play a key role in the
unlocking of captive capacity in the states and support the state utilities in their endeavor to
fulfill their universal service obligations
After about seven months of continued operations now the Power Exchange India Limited
believes that the power markets in India are ready to take the next step in their development
process through the introduction of the longer tenure products on PXIL. PXIL has developed a
new proprietary trading engine and the products can be traded using it. It would also utilize the
bilateral open access system. All these products are physical delivery based and would enable
market participants to procure and sell electricity through PXIL on week ahead, first, second and
third month ahead basis. Trading on the exchange would be now convenient and easy for all
participants with the structure of contracts being standardized and also standardized risk
management systems.
47 | P a g e
Mechanism used in PXIL
The mechanism used in PXIL is also similar to that of IEX because the whole current day ahead
trading market uses a closed double sided bidding mechanism for a uniform price auction. This
bidding mechanism is very useful for obtaining a uniform hourly market clearing price for
smaller volumes and transactions in the day-ahead market. But it might have some issues for
much larger transactions which are expected for the longer tenure projects.
The revised inter-state bilateral open access regulations operate the electricity trading system
developed by PXIL. PXIL’s trading system uses an auction mechanism where the trading session
is divided into multiple sessions meant for sell, buy, trade-matching and price revision. These are
divided into 24 time slots in a day with each time slot of 1 hour. For each time slot a particular
price is bided and a particular quantum at that price is fixed for buy or sell. Suppose we are a
buyer and we put the bid price as Rs.4 per unit and the quantum as 100 MW then if the Market
Clearing Price for that particular time slot is less than Rs.4, say Rs.3 then we will get the quantity
of 100 MW. The case is reversed with the seller i.e. if the bid price is Rs.4 with a quantum of 100
MW and the market Clearing Price for that particular time slot is more than Rs.4 then the entire
100 MW will be cleared. The trades are matched through PXIL’s newly developed proprietary
trading engine.
PXIL believes that order matching systems for power trades are best evolved in keeping with the
peculiarities of the local market conditions. Hence PXIL has developed a trading engine software
through a consultative process with the market participants ranging from utilities to smaller
captives, as well as regulators so as to provide the Indian power market with the most suitable
product. The in-house development of the trading and matching system also provides PXIL with
the flexibility to accommodate changes in continuously evolving Indian power market.
The contract features of the traded products e.g. contract structure, penalty structures, risk and
margin system for longer tenure products have been kept in line with the present trading
transactions undertaken in the short term bilateral trading market.
The sanctity and the surety of the trades matched on the exchange are ensured by creating a risk
management mechanism in the form of adequate margins to cover the trades. Therefore the risk
management mechanisms take care of defaults in payments by buyers, defaults in supply by
48 | P a g e
sellers, arbitrary termination of contract etc. the margins are collected in the form of an initial
margin after trade matching, daily margin of a pre-determined value during delivery and extra
ordinary margins to cover penalties of default. To provide the market participants with flexibility,
margin required can be built in the form of bank guarantee, bank limits, letter of credit, fixed
deposits and cash. Furthermore, care has been taken to ensure that the value of the margins is far
lower than that required in the short term bilateral transactions otherwise.
PXIL is of the opinion that by providing ease, transparency and certainty to market participants
these products would change the way power is traded in India and it would take the Indian power
market to the next stage of development.
7.3. Congestion Management
Congestion management is a very important phenomenon in the effective trading of power.
Transmission congestion occurs when there is not enough transmission capacity to
simultaneously accommodate all requests for transmission within a region. If in case the
congestion is not there then there shall be no restriction of access to the interconnection and no
specific procedure for access to transmission service.
The cause of congestion can either be temporary or structural. The occurrence of temporary
bottlenecks is relatively rare and maybe because of outages for maintenance work, technical
faults or particular market conditions. The structural bottlenecks are mainly a result of the level
of expansion of the grid and the localization of the generation and consumption within the grid.
These bottlenecks normally occur over longer periods of time or at regular intervals. But there is
very little difference between the two types of congestion. It is however important to determine
the kind of congestion faced with so as to employ the best method for dealing with it.
Principles of Congestion management
In principle the congestion can only be relieved physically by reducing generation or increasing
consumption on the surplus side of the bottleneck and conversely increasing the generation ot
reducing consumption on the shortfall side. Different methods are there for managing the
congestion depending on the various time phases of the day. These methods should be based on
the following principles –
49 | P a g e
1. Economic efficiency and promotion of competition.
2. Maximizing of the amount of capacity available and its usage.
3. Transparency to the network users on a non discriminatory basis.
4. Efficient system operation

Chapter 8: OPEN ACCESS
8.1. OPEN ACCESS AND TRADING:
The Electricity Act, 2003 has come into force from 10th June, 2003 and it repeals the Indian
Electricity Act, 1910; Electricity (Supply) Act, 1948 and Electricity Regulatory Commissions
Act, 1998. The performance of the state electricity boards have deteriorated over the years and
the cross subsidies have reached unsustainable levels. This is the reason why some of the states
in the country have gone in for reforms. This includes the unbundling of the state electricity
boards by creating separate Generation, Transmission and Distribution Companies. The
implementation of the Act has been one of the most important steps in the history of the power
sector. Due to this, newer concepts like power trading and open access have come into force.
The open access phenomenon helps the players to utilize the capacities and transmit power from
generation to the load centre. This will mean utilization of existing infrastructure and easing of
power shortage. Trading has now become a licensed activity and it also helps in the innovative
pricing leading to competition which in turn results in lowering of tariffs.
8.2. DEFINITION OF “OPEN ACCESS” IN THE EA’03:
The non-discriminatory provision for the use of transmission lines or distribution system or a
associated facilities with such lines or system by any licensee or consumer or a person engaged
in generation in accordance with the regulations specified by the Appropriate Commission”
A MORE GENERAL DEFINITION OF “OPEN ACCESS”: Open Access enables the non-
discriminatory sale/purchase of electric power between two parties using the system and not
blocking it on unreasonable grounds.
EXAMPLE: Suppose a company from Maharashtra wants to sell 100 MW to a Discom-A
in Andhra Pradesh.
Following steps need to be taken:

8.3. IMPACT OF “OPEN ACCESS SYSTEM” ON DISCOM’S:
The Electricity Act 2003 has made it mandatory for the immediate implementation of the open
access. The implementation of the open access will serve the consumer interests but there is also
some contradicting views regarding the implications of the open access on the Discoms. The first
view being that the competition in the power generation will bring down the ultimate costs to the
consumers. Cost reduction is possible only by reducing the T&D losses, keeping under control
the operating costs and keeping the additional power purchase costs low. Given the facts that
power purchase costs keep increasing and the HT tariff has been mandated to be brought down
closer to the average costs (thereby reducing the cross-subsidy) according to a fixed time
schedule to be set by the regulator, the first group argues that taking up additional liability by
way of HT consumers at such high marginal costs of power purchase would be financially
imprudent for the electricity entities. The other view is that electricity entities have heavy
responsibility to meet the needs of agricultural consumers and small domestic consumers at a
lower rate than the average cost. Consumers who are currently the HT consumers and
commercial consumers paying a higher tariff are providing the means to do this. If such
consumers walk away from Grid supply subsidy from Government will have to increase. The
correct position would depend on the state-wise situation regarding relative tariff of the different
consumers, the possible rates of growth of category wise consumption and the potential for
purchasing additional power at low rates in the future.

Chapter 9: Regulatory role in Trading
9.1. CERC Regulations for Short Term Open Access
Criteria for allowing short term open access
Short term open access can be given only if it can be accommodated by utilizing-
Inherent design margins
Margins available due to variation in power flows
Margins available due to in built spare transmission capacity created to cater to future
load growth
Allotment priority
The long term open access user gets the first preference, next is the medium term user and then
the short term user
If the capacity sought to be reserved by the open access users, at a given point of time is less than
the available capacity at that point of time, each short term open access user shall pay the
transmission or wheeling charges in accordance with regulation 14.
Procedure for short term open access user
1. First the application for access of transmission/distribution should be submitted to the SLDC.
2. The details such as capacity needed, inspection point, drawl point, duration of availing open
access, peak load, average load, and such other auxiliary information that may be specified
by the SLDC should be mentioned in the application.
3. A non refundable fee of Rs.5000 is payable to the SLDC along with the application in the
manner decided by the SLDC.
4. The reserved capacity should not be transferred by a short term open access user to any other
open access user.
53 | P a g e
Non-Utilization of Reserved Transmission Capacity by Short-Term Open Access
User
If in case, a short term open access user is unable to utilize the full reserved capacity or a
substantial part of it then it must inform the concerned SLDC i.e the State Load Dispatch
Centre along with the reasons of its inability to utilize the full capacity. It is also required
that the reserved capacity must be surrendered.
The reserved capacity of a short term open access user may be reduced or even cancelled
by the concerned State Load Dispatch Centre if the user frequently under utilizes the
reserved capacity.
The short term open access user who surrenders the reserved capacity or whose reserved
capacity is reduced or cancelled under clause (ii), shall bear the transmission charges or
the wheeling charges and the scheduling and the system operation charge based on the
original reserved transmission capacity for seven days or the period of reservation
surrendered or reduced or cancelled, as the case may be, whichever period is shorter.
When a short term open access user surrenders a reserved capacity the capacity available
thereof under clause (i) or clause (ii) above, may be reserved for any other short term
open access user in accordance with these regulations.
Open Access Charges
The following Open Access Charges shall be payable by Open Access users. These charges will
be determined and notified by Commission from time to time through separate order. The
charges for open access shall consist of one or more of the following charges:
(i) Transmission / Distribution (Wheeling) charges
The charges for use of the system of the licensee for intra-state transmission or distribution
except intervening transmission facilities shall be regulated as under, namely:-
54 | P a g e
1. The annual charges shall be determined by the Commission in accordance with the
terms and conditions of tariff notified by the Commission from time to time and after
deducting the adjustable revenue from the short-term users, these charges shall be shared
by the long-term users;
2. (a) The charges paid by the short term users shall be calculated by the following
method:
ST RATE = 0.25 x [TSC/ Av CAP]/ 365
Where:
ST RATE is the rate for short-term open access user in Rs per MW per day. "TSC" means
the Annual Transmission / Distribution Charges of the transmission or distribution
licensee for the previous financial year determined by the Commission. "Av CAP" means
the average capacity in MW served by the system. The capacity of the transmission
licensee in the previous financial year shall be the sum of the generating capacities
connected to the transmission system and contracted capacities of other transactions
handled by the system of the transmission licensee. The capacity of the distribution
licensee in the previous financial year shall be the sum of the distributed load for the
licensee. (b)The transmission charges payable by a short-term open access user in case of
un-congested transmission corridor shall be levied as under, namely:-
Up to 6 hours in a day in one block: 1/4th of ST RATE
More than 6 hours and up to 12 hours in a day in one block: ½ of ST RATE
More than 12 hours and up to 24 hours in a day in one block: equal to ST RATE
(c) Every licensee shall declare the rate in Rs/ MW per day which shall remain fixed for
a period of one year, provided further that, where reservation of capacity has been
done consequent to bidding in the manner specified in Regulation 6, the ST RATE
shall be taken as the floor price for bidding.
55 | P a g e
3. 25% of the charges collected from the short-term open access user shall be retained by the
licensee and the balance 75% shall be adjusted towards reduction in the charges payable
by the long-term open access users.
4. The rates, charges and terms and conditions for providing the use of intervening
transmission facilities would be mutually decided by the licensees. Provided that any
dispute on the extent of surplus capacity available or disagreement on the rates, charges
and terms and conditions, shall be adjudicated upon by the Commission. However the
rates, charges and terms and conditions shall be fair and reasonable and may be allocated
in proportion to the use of such facilities.
(ii) Cross-Subsidy Surcharge
In addition to transmission charges and wheeling charges, a consumer availing open access to
the transmission system/distribution system shall pay a Cross-Subsidy Surcharge.
The Open Access users, except those availing open access facility to transfer power from
their captive generating plants to the destination of own use, shall pay the (cross-subsidy)
surcharge to the Distribution Licensee of their area, as determined by the Commission from
time to time under section 42 (2) of the Act.
The amount of surcharge shall be so calculated as to meet the current level of cross subsidy
from that category of consumers and shall be paid to the distribution licensee of area of
supply where the consumer is located.
Such surcharge and cross subsidies shall be progressively reduced and eliminated by the
Commission.
(iii) Additional Surcharge
(a) A consumer availing open access and receiving supply of electricity from a person other
than the distribution licensee of his area of supply shall pay to the distribution licensee an
additional surcharge, in addition to wheeling charges and surcharge, to meet the fixed
cost of such distribution licensee arising out of his obligation to supply as provided under
sub-section (4) of section 42 of the Act.
56| P a g e
(b) The distribution licensee whose consumer intends to avail open access shall submit to the
Commission within thirty days of receipt of application an account of fixed cost paid by
such open access user which the licensee is incurring towards his obligation to supply.
(c) The Commission shall scrutinize the statement of account submitted by the licensee and
obtain objections, if any, of the consumer and determine the amount of additional
surcharge payable by the consumer.
(d) The additional surcharge shall be levied for such period as the Commission may
determine but not normally exceeding one year.
(iv) Scheduling and System Operation Charges
(a) The scheduling and system operation charges payable to State Load Dispatch Centre by
long–term open access users shall be same as determined by the Commission under
Section 32 of the Act read with GERC (Levy and collection of fees and charges by
SLDC) Regulations, 2005.
(b) The scheduling and system operation charges of Rs.2000/-per day or part of the day shall
be paid by a short-term open access user to State Load Dispatch Centre
(c) The scheduling and system operation charges collected by the State Load Dispatch Centre
in accordance with clause (b) above shall be in addition to charges determined by the
Commission under Section 32 of the Act. These will be however adjusted in the
subsequent ARR of SLDC.
Explanation
Scheduling and system operation charges shall be payable by a supplier as well as his
consumer availing open access under these Regulations.
(v) Reactive Energy Charges
The payment for the reactive energy charges for the open access user shall be calculated
in accordance with the scheme applicable.
57| P a g e
(vi) Any other charges as may be specified by the Commission from time to time shall be
payable by the open access user.
UI Charges under Intra-State Availability Based Tariff (ABT)
The Commercial settlement of Unscheduled Interchange charges (UI charges) under Intra-State
ABT shall be done according to the Inter-State ABT being followed for Inter-State Transactions
with the following, additions/variation.
(i) A consumer opting for open access shall continue to be treated according to the rules
applicable to a normal consumer in the equivalent category of the Discom. Thus he will
be penalized for deviating from his scheduled drawl which may be detrimental to the grid
either by way of frequency or voltage of the grid. At the same time he will not be paid
any UI charges for changing his schedule even if it be helpful to the grid.
(ii) A generating station with a total capacity of generation upto 15 MW may operate
under UI regime and inject power (specially during peak load condition) when there is an
overall shortage and will be paid for such injection of generation into grid at the UI rate
as determined by SLDC.
(iii) Generating Stations with a total capacity above 15 MW shall be regulated as follows
according to CERC stipulations to avoid gaming:
(a) Any generation up to 105% of the declared capacity in any time block of 15 minutes and
aggregated averaging up to 101% of the average declared capacity over a day shall not be
construed as gaming, and the generator shall be entitled to UI charges for such excess
generation above the declared capacity scheduled generation (SG).
(b) For any generation beyond the prescribed limits, the State Load Dispatch Centre shall
investigate so as to ensure that there is no gaming, and if gaming is found by the State Load
Dispatch Centre, the corresponding UI charges due to the generating station on account of
such extra generation shall be reduced to zero and the amount shall be adjusted in UI account
of beneficiaries in the ratio of their capacity share in the generating station.
58| P a g e

1. Applications received within three days prior to the date of scheduling and up to 15:00 Hrs. of
the day immediately preceding the day of scheduling shall be treated as having been received
together for processing and shall have same priority.
2. Applications for Day Ahead transactions shall be processed only after processing of the
Collective Transactions of the Power Exchange(s).
3. Pro-rata scheduling acceptance shall be given in case scheduling requests of the Applicants is
for more than the margins available.
PROCEDURE FOR SCHEDULING OF BILATERAL TRANSACTION
IN A CONTINGENCY
1. In the event of a contingency, the buyer or in its behalf, a trader may locate, and the power
exchange may offer its platform to locate, a source of power to meet short-term contingency
requirement and make an Application to the Nodal RLDC.
2. Nodal RLDC shall accept such Application only after 1500 hrs of the day immediately
preceding the day of scheduling.
3. Nodal RLDC shall take steps to incorporate such Bilateral Transactions in Day Ahead
schedules/same -Day schedules, as the case may be. In case of Same Day, the transaction shall
be scheduled from the 6th time block, counting the block in which acceptance is accorded as the

INCORPORATION OF BILATERAL TRANSACTIONS IN DAILY
SCHEDULES BY THE RLDCs
1. RLDCs shall incorporate the Bilateral Transactions (as per the acceptance accorded) in the
Daily Schedules of the Regional Entities. The concerned SLDCs shall also incorporate such
inter-State transactions to / from the point of injection / drawl in the Daily schedules issued by
them.
2. The average energy losses shall be applied, as estimated on weekly basis, by Regional Load
Dispatch Centre for regional transmission system and as displayed in their respective website.
For State transmission system, losses shall be applied as specified by the respective State Load
Dispatch Centre. The losses in the system shall be compensated by less drawl by the Drawee
Utility. The net drawl schedule for Buying Utility will be the drawl schedule minus the estimated
losses in the involved transmission system.
3. While finalizing the net drawl schedule / net injection schedule of Entities, each transaction
will have a resolution of 0.01 MW at each State/inter-Regional boundaries.
4. The ramp-up and ramp-down if required, in the Daily Schedules (issued by the RLDC) on
account of such transactions, shall commence at the time of commencement of the transaction
and shall end at the time of termination of the transaction respectively.
REVISION OF SCHEDULE
1. The Short-Term Open Access Schedules accepted by the Nodal RLDCs in case of “Advance
Scheduling” or “First-Cum-First Served basis” may be cancelled or revised downwards by the
Applicant by giving minimum two (2) days notice. The notice period shall be excluding the day
on which notice is served and the day from which revised schedules are to be implemented.
2. The accepted schedules for Day-Ahead transactions and transactions in a Contingency shall
not be revised or cancelled.
72| P a g e
3. The Applicant, who has requested for revision or cancellation of the accepted schedule as
above, shall pay the Transmission Charges and Operating Charges as per the originally accepted
schedule, if the period of revision or cancellation is up to two (2) days. If the period of revision
or cancellation exceeds two(2) days, the Transmission Charges and Operating Charges for the
period beyond two (2) days shall be payable as per the revised accepted schedule and for the first
two (2) days as per the original schedule.
For example: Say an Applicant has been scheduled for 10 days from 21st day of a month to 30th
day of a month for 100 MW on round the clock basis (i.e. for 2400 MWh per day). If this
Applicant, on or before 18th day of that month, submits request for revision of schedule to 50MW
on round the clock basis (i.e. 1200 MWh per day), the revised schedule will get implemented
from the beginning of the transactions (i.e. 21st day of the month). The Applicant shall pay the
Transmission Charges for 2400 MWh per day for the period from 21st to 22nd day of the month
whereas for the period from 23rd day to 30th day of the month, Transmission Charges shall be
payable for 1200MWh per day. However, if the Applicant requests for such revision on 20th day
of the month, his request will be implemented from 23rd day of the month. He shall pay
Transmission charges for 2400 MWh per day for 2 days i.e. from 23rd to 24th day of the month
and for the remaining period he shall pay the Transmission Charges based on 1200MWh per
day.
4. The margins becoming available as a result of such revision or cancellation shall be available
for scheduling to any other Applicant in accordance with relevant provisions of Regulations on
Open Access.
5. The short-term customers granted short-term open access prior to 15.06.2009 shall also be
eligible for Cancellation/downward revision of Schedule by giving two days notice and by
paying minimum two days transmission charges as per Regulation 15. The refund of
transmission charges shall be in accordance with the rate at which the transmission charges were
paid by the respective customer.
73| P a g e
CURTAILMENT IN CASE OF TRANSMISSION CONSTRAINTS
1. Bilateral Transactions shall be reduced or cancelled by the Regional Load Dispatch Centre, if
the Central Government allocates power from the Central Generating Station or Stations in a
Region to a person in another Region and such allocation, in the opinion of the Regional Load
Dispatch Centre, cannot otherwise be implemented due to Congestion in the inter-Regional
corridor. In the event of reduction or cancellation of already accepted schedules of Bilateral
Transactions, the Applicant shall be suitably intimated by the RLDC.
2. When because of transmission constraint or to maintain grid security as decided by RLDC, it
becomes necessary to curtail power flow on a transmission corridor, the transactions already
scheduled, would be curtailed in the manner, which in the opinion of RLDC, would relieve
transmission constraints/ enhance grid security. Subject to the provisions of the Grid Code, while
cancellation or curtailment of any transaction, among short-term, medium term and long-term
transactions, short-term transactions shall be cancelled or curtailed first, followed by medium
term and thereafter long-term transactions. Short-Term Open Access Bilateral Transactions
would be curtailed first followed by the Collective Transactions.
3. In case of transmission constraint or otherwise when Long Term Customer’s power from one
Region to another needs to be re-routed through the third Region, RLDC shall allow such re-
routing to the extent of the surplus margin available without curtailing the existing Long-Term,
Medium Term and Short- Term Open Access transactions.
4. In case of curtailment of the accepted schedules for any particular day for the reasons of
transmission constraints or due to allocation of power from Central Generating Station from one
Region to the person in other Region, the Transmission Charges for that day shall be payable on
pro-rata basis in accordance with the transactions finally scheduled. Provided that the Operating
Charges shall not be revised in case of curtailment.

Chapter 10: Findings and Observations
A Market Monitoring Cell (MMC) was set up in CERC in August 2008. As advised
by the Steering Committee of MMC, MONTHLY REPORT ON SHORT-TERM
TRANSACTIONS OF ELECTRICITY is prepared. Here, the “short-term transactions of
electricity” includes the electricity transacted through Trading Licensees, Power Exchanges and
Unscheduled Interchange.
10.1. Volume of Short-term Transactions of Electricity
During the Month of March 2009, total electricity generation excluding generation from
renewable sources and captive power plants in India was 64841.89 MUs. Of the total electricity
generation, 4248.55 MUs (6.55%) transacted through short-term i.e. 1941.68 MUs (2.99%)
through Bilateral (through traders and direct between distribution companies), followed by
1878.26 MUs (2.90%) through Unscheduled Interchange (UI) and 428.61 MUs (0.66%) through
Power Exchanges (IEX and PXIL). Of the total short-term transactions, Bilateral constitute
45.70% (39.93% through traders and 5.77% direct between distribution companies) followed by
44.21% through UI and 10.09% through Power Exchanges. The percentage share of electricity
traded by each trading licensee in the total volume of electricity traded by all trading licensees is
provided in. Here the volume includes the volume traded by licensees through power exchanges
also. There are 41 trading licensees as on 31.3.2009, however only 12 licensees are undertaking
trading during March 2009. Top 5 trading licenses are having share of 85.65% in the total
volume traded by licensees. The volume of electricity transacted through IEX and PXIL was
377.17 MUs and 51.44 MUs respectively. The volume of total Buy bids and Sale bids was
719.68 MUs and 640.90 MUs respectively in IEX and 67.29 MUs and 82.04 MUs respectively in
PXIL. The gap between the volume of buy bids and sale bids placed through power exchange
shows that there was more demand (1.12 times) when compared with the supply offered through
IEX and it was less demand (0.82 times) when compared with the supply offered through PXIL.

10.2. Price of Short-term Transactions of Electricity
(1) Price of electricity transacted through Traders: Weighted average sale price has been
computed for the electricity transacted through traders and it was Rs.7.43. The weighted average
sale price also computed for the transactions during Round the clock (RTC), Peak and Off-Peak
periods separately and the sale price was Rs.7.35, Rs.8.08 and Rs.7.53 respectively. Minimum
and Maximum sale price was Rs.2.44 and Rs.11.69 respectively.
(2) Price of electricity transacted Through Power Exchange: The Minimum,
Maximum and Weighted Average Price has been computed for the volume transacted through
IEX and PXIL separately. The Minimum, Maximum and Weighted Average Price was Rs.0.60,
Rs.13.10 and Rs.8.33 respectively in IEX and Rs.0.00, Rs.13.10 and Rs.8.54 respectively in
PXIL.

(3) Price of electricity transacted Through UI: All-India UI price has been computed for NEW
Grid and SR Grid separately. The average UI price was Rs.4.85 in the NEW Grid and Rs.8.20 in
the SR Grid. The power deficit is more in the Southern Region when compared with other
regions; therefore, the UI price was higher in the SR Grid when compared with the UI price in
the NEW Grid. Minimum and Maximum price of UI was Rs.0.24 and Rs.10.00 respectively in
the New Grid and Rs.0.00 and Rs.10.00 respectively in the SR Grid.

Power Ltd, Chhattisgarh, Delhi, Punjab and Haryana and top 5 states purchasing 71.07% of
the volumes are Rajasthan, Madhya Pradesh, Tamil Nadu, Andhra Pradesh and Karnataka.
Of the total Power Exchange transactions, top 5 states selling 86.68% of the volumes are Gujarat,
Chhattisgarh, Delhi, Rajasthan and West Bengal and top 5 states purchasing 99.50% of the
volume are Andhra Pradesh, Tamil Nadu, Maharashtra, Rajasthan and Karnataka. Of the total UI
transactions, top 5 states exporting 53.58% of the volume are Chhattisgarh, Delhi, Madhya
Pradesh, Gujarat and West Bengal and top 5 states importing 48.92% of the volumes are
Haryana, Maharashtra, Uttar Pradesh, Andhra Pradesh and Tamil Nadu. State-wise total net
short-term transactions of electricity i.e. volume of net transactions through bilateral, power
exchange and UI was shown in Table-13. Top 5 states those selling electricity are Chhattisgarh,
Delhi, Jindal Power, Gujarat and West Bengal and top 5 states those purchasing electricity are
Andhra Pradesh, Tamil Nadu, Rajasthan, Madhya Pradesh and Karnataka.

Chapter 11: Conclusion
Power trading in India reached new heights with the evolution of the power exchanges in 2008.
The trading of power has become more convenient with the help of these exchanges. The
implementation of the Electricity Act, 2003 has also played a major role in making this possible
as it makes the trading of power across regions a licensed activity. The trading of power was also
prevalent before the existence of the exchanges but the level of risk was more in those
agreements. The exchanges mitigate these risks and assure the traders of their returns. As far as
the bilateral agreements are concerned they are helpful for buying or selling power at a future
date regardless of what the price is at that particular time. This way the traders can mitigate the
risks as well.
Although there are a lot of benefits from short term power trading, there is still a long way to go.
There is no technical barrier as such in making the electricity market more flexible. Shortening of
the time between the clearing of the market and the delivery can also be looked into for quick
and efficient supply. Moreover, the procedure of bidding in IEX is a bit complex as compared to
PXI. The concept can be made simpler so that it is more user-friendly. The exchanges are also
coming up with term-ahead markets which can be a week ahead or month ahead. This is an
important step in the development of exchanges towards month ahead and week-ahead markets.
The exchanges can also take important lessons from international markets like those in Europe or
the NORD Pool etc. This is because the international markets had to face a lot of hindrances in
the initial stages and they successfully dealt with all these problems. All this will not only make
the power system of the country effective but will also improve the growth of the power sector in
the country.
