Consultancy Service for Computerized Maintenance Management System
Under Enhancement & Strengthening of Power Network in Eastern Region project
Terms of Reference
1- Background and Context
Bangladesh’s economy has performed well over the past decade and the country embarks in an
ambitious infrastructure development program to sustain the economic growth. This include the power
sector which has to meet an electricity demand projected to grow by more than 10 percent per annum
in the medium term due also to efforts to reach universal access.The installed generation capacity
doubled over 5 years to reach 11.8 GW in 2016 and the Government’s plan is to double it by 2021
and reach 50 GW by 2041.
Wheeling such capacity to the final users require not only to expand the transmission system but also
to improve significantly the O&M of the system in order to ensure the quality and reliability of the
electricity supply nationwide. Addressing the challenge is the responsibility of The Power Grid
Company of Bangladesh (PGCB) which own, operate and expand the country’s power transmission
assets1.
Currently PGCB is managing 5,377 km of HV lines (mainly double circuit 400, 230 and 132 KV) and
141 substations. It is planned to add 3,098 km lines and 106 S/S by 2020 and additional 3,005km and
90 s/s by 2025. The details of the infrastructure projections are given in the table below and in Annex
2.

If PGCB keep current O&M practices, doubling the size of the infrastructure in less than 10 years implies major challenges to ensure sustainability of the transmission assets which is key to the reliability of the grid network. Indeed, the current practices are mainly based on time-based and breakdown maintenance with high impact on the system availability and the cost of service.
The current organization/structure of the system maintenance is given in Annex-1. More than 2,000 staff are involved (including 1,141 engineers and 709 technical staff). The total expenditure
2for
maintenance almost double between FY 2011/12 and 2015/16 from 4.2 to 7.2 billion BDT (i.e. USD54 to 90.3 million). This does not include the losses due to unserved energy related to planned outages for maintenance which may increase due absence of live line maintenance capacity.
Currently, data collection is done in PGCB from different Grid Maintenance Divisions (GMD) as per the requirement following QMS (Quality management System) guidelines. The Research & Technical
1Institutional structure of the PGCB highlighting maintenance portion is shown in Annex 1
2including Repair & Maintenance, Salaries & Benefits of O&M Staff, Depreciation etc.

Support Department (RTS) is responsible for collection of critical maintenance data centrally. They have developed a online data collection and analysis system which is not fully operational yet.
It exists General guidelines for different PGCB departments regarding maintenance as detailed in table2. However, no certification/qualification program for staffs is in practice yet. Table 2: Existing maintenance guidelines for PGCB Departments

In total, PGCB needs to change O&M strategy to cope with the rapid expansions of the transmission
system. Handling the expanded system with current maintenance practices and tools will lead to low
level of reliability and unbearable level of staffing. Activities are undertaken to improve the operating
rules under the implementation of FGMO and upgrading of SCADA/Dispatch system. Efforts are also
ongoing to come up with standardization of design and technical specifications of major equipment.
This activity will complement by focusing on a comprehensive maintenance and asset management
policy to deliver reliable power at an optimal cost.
2- Objective of the assignment
PGCB intend to hire a consultancy firm to review current policies, procedures and practice which includes but not limited to the followings:
a) Maintenance activities of various departments of PGCB that maintain critical elements of Bangladesh National Grid System[Critical elements means, failure of such element can cause power outage or increase the risk of power outage]
b) Procurement activities that can affect the quality of critical elements ofBangladesh National Grid System
c) Human resource recruitment and development activities of PGCB that can affect the maintenance of critical elements of Bangladesh National Grid System
In accordance with the above the consultant will also assess organization of the maintenance
departments, establish baseline for cost and performance. It will then propose a new strategy in line
with international standards, based on an inclusive process involving all relevant department of PGCB
and combining reactive, predictive and pro-active approaches. This will include (i) the progressive
introduction of Reliability-Centered-Maintenance (RCM) analysis based on available data, (ii) the
definition of a new policy framework, (iii) institutional re-organization of the maintenance, (iv) standard
guidelines and procedures during all the equipment/systems lifetime and (v)arrange adequate training
workshops to implement RCM in PGCB
3- Detailed Scope of work
The assignment will be undertaken in three (3) different phases as described hereunder:
3.1. Phase 1 will focus on:
