1.3
The BERC in exercise of power vested in it section 62(1) (d) read with section 62(3) and
section 64(3) (a) of the Electricity Act 2003 and the BERC Terms and Conditions for
Determination of Tariff Regulations, 2007 and other enabling provision in this behalf, issued
Tariff order for FY 2012-13 for the supply of electricity by erstwhile BSEB in the state of Bihar.
In this Order, the BERC also issued directions to erstwhile BSEB to prepare separate
Business Plans for Generation, Transmission and Distribution functions and submit Multi Year
Tariff petition for Three years commencing from FY 2013-14.
1.4
Accordingly, the erstwhile BSEB, in compliance with the BERC Terms and Conditions of Tariff
Regulations, 2007 has prepared a separate Business Plan for Transmission function for the
three year control period beginning with FY 2013-14. With unbundling of erstwhile BSEB from
1st November, 2012 the Holding Company (on behalf of Bihar State Power Transmission
Company) has prepared Business plan for the three years control period (from FY 2013-14 to
FY 2015-16) for the Transmission Company (Transco).The objective of the Business Plan is
to project the Capital Investments, Financing costs, various expenses and performance of the
Transmission function of BSEB during the MYT control period.

Approach to Development of Business Plan
1.8
The Business Plan for the Transmission Company is prepared based on the review of
Bihar State Power Holding Company
Page 6
Business Plan for Bihar State Power Transmission Company
erstwhile BSEB’s Transmission profile, challenges faced in intra-state transmission and
operational performance. While preparing the Business Plan, past trends of various
parameters has been considered so as to project the same appropriately for the years
covered under the control period.
1.9
Broadly, the capital investment is determined based on the analysis of projected demand
growth in electricity distribution sector commensurate with the economic growth in the state,
and generation capacity additions/ increased evacuation requirement vis-à-vis the available
transmission capacity. Further, based on these growth projections, requirement of additional
transmission lines and substations or augmentation of existing transmission capacity and
replacement of transmission lines are planned.
1.10
Accordingly, the Transmission Business Plan for the control period would include following:
1.11
•
Capital Investment Plan: Capital investments in the transmission function are required
for both, addition of new lines and substations necessary for allowing flow of increased
power onwards to the distribution utilities as well as system strengthening and
improvement schemes for increased reliability and grid stability. The planning of Capital
Investment is essentially commensurate with the anticipated load growth and quality
improvement measures. The Capital Investment Plan broadly includes the proposed year
wise Capital Investment towards new assets to be added and R&M at different
transmission voltages.
•
Capitalisation schedule and Funding of Capex: The Business Plan also includes the
schedule of capitalisation for the proposed investments, separately for the new schemes
and for R&M works. Considering the year wise amount envisaged under BRGF, the
funding of Capital Investment has been proposed.
•
Major Transmission Assets: The major Transmission Lines and Substations proposed
to be added, R&M and augmentation works along with capacity additions have also been
summarised in this Business Plan.
Each of the above mentioned components of the Business Plan has been detailed out in
subsequent chapters. The Business Plan has been prepared according to the BERC Terms
and Conditions of Tariff Regulations, 2007, the Electricity Act, 2003 and applicable rules/
regulations/ provision of the law, Standard Accounting Practices and generally accepted O&M
norms etc.

Energy Scenario
2.3
The power supply position in the State of Bihar remained very poor and consequently the
peak demand deficit in the State has comparatively remained worse than the national
average for the country. The deficits in terms of energy availability and peak demand for Bihar
in FY 2010-11 were 13% and 22.5%; whereas the same at national level were 8.5% and 9.8%
respectively. As per CEA’s report, the peak deficit was around 14.4% and energy requirement
deficit was 21.3% for FY 2011-12. The details are represented in the charts below:

Bihar has witnessed sharp increase in the economic growth during 11th plan period mainly on
account of the developments in the secondary sector which has led to a sharp rise in the percapita income. However, the same is yet to reflect in the energy/ power sector growth, as
evident from the per capita energy consumption of state, which is very low at 122 kWh in
comparison to the national average of 780 units. The centrally sponsored schemes like
Restructured-Accelerated Power Development and Reforms Programme (R-APDRP) and
Rajiv Gandhi Grameen Vidyutikaran Yojna (RGGVY) are being implemented in the state with
specific focus on distribution sector improvement.

2.5
South and North Discoms mainly relies for its energy requirement on Central Sector
Generating Stations viz. NTPC, NHPC, PTC and others as the State generating capacity is
not adequate to meet the supply needs. Presently, the overall Transmission & Distribution
losses being incurred by two Discoms are around 41%. The transmission system needs to be
strengthened suitably for smooth interface with the inter-state network in the country and for
meeting requirement of wheeling the power.
2.6
In order to strengthen the transmission network, the erstwhile BSEB has undertaken various
transmission network capacity addition, augmentation and improvement projects for achieving
its objective of making available reliable power across the State. The Central Government
promoted initiative – Rastriya Sam Vikas Yojana (RSVY) is one such scheme focussed on
strengthening the Transmission and Distribution network and reduction of T&D losses.
2.7
The Transco is also implementing various capacity addition schemes funded by the Asian
Development Bank (ADB) proposed under Central Government sponsored Backward Region
Grant Fund (BRGF) programme. Further, the Company had been taking assistance from
Bihar Government out of the allocated Five Year Plan fund for energy sector.
Economic Growth in Bihar
2.8
The State of Bihar has experienced tremendous economic growth since the last few years.
The developmental activities in the various sectors in the state have resulted in impressive
th
growth rate of the state. During the 11 plan period against the all India growth rate of 7.94%,
Bihar achieved a growth rate of 12.08% at constant prices. The per capita income of Bihar
grew at 10.47% during the 11th plan, which is 4% higher than the same for the country. The
primary sector of the state is experiencing a decline in the share of state’s domestic product –
from 37.49% in 2000-01 to 18.12% in 2011-12 (Adv.). This is due to the increased pace of
developments in the secondary sector.
Twelfth plan objectives for growth trends
2.9
The State Government of Bihar has set following objectives to meet 12-13% growth rate
during the twelfth plan period:
•
•
•
•
•
•
•
2.10
To attempt for a high growth rate (7%) in Agriculture and allied sectors by adopting the
strategy of the Rainbow Revolution;
To develop infrastructure at a much higher pace;
To focus on industrialization;
To emphasize the development of the social sector further, particularly education and
health;
To make a sustained effort for reduction in poverty;
To make a substantial increase in the income level of the lowest strata of society; and
To make an attempt at equitable regional development.
Due to rapid growth in Bihar, the current level of demand is anticipated to increase drastically
from current level of 2000 MW to 6000 MW in near future. To facilitate the growth of the State
and in order to meet the increasing demand for power, the state Government of Bihar has
planned various power generation capacity addition programmes and allocation of fresh/
increased power from upcoming Central and Private sector projects. With the materialisation
of these capacities, the Transmission system needs to be adequately enhanced and
strengthened so as the power from various new/ additional generating sources is evacuated
efficiently for further transmission and supply to the consumers at distribution end in the State.

Transmission Business – Issues and challenges
3.1
Transmission network serves as an important link between the Generation and Distribution
segments of electricity supply business. The issues and challenges pertaining to the
Transmission business are mostly in terms of keeping up with the growth needs of the other
two segments. While the growth in the demand along with increasing electrification end drive
the need to meet the peak demand and energy requirement by arranging supply from internal
and external generation sources, the transmission system has to be strengthened adequately
and timely for maintaining grid stability and supply quality.
Demand-Supply Projections
3.2
Post separation from Jharkhand, Bihar is left with only BTPS, MTPS and Koshi Hydro Power
Stations which is very limited power generating capacity in view of the requirements of the
State. The State Government has taken several initiatives in order to fulfil the supply needs of
the State in terms of setting up Independent Private Projects (IPPs) and State Sector projects
and arranging share from central sector projects. The total power available including the
private and central allocations to the state of Bihar is going to touch around 5300 MW in FY
2015-16 from current level of around 2300 MW.

by Bihar.
•
•
•
A per-capita electricity consumption of level 770 kWh;
Electrification of additional 17,000 villages; and
Capacity addition programme of 6600 MW up to FY 2015-16 and 14000 MW by FY

Requirement and the Availability of power, the demand-supply gap is envisaged to be
reduced and the state would be able to meet its peak demand by FY 2015-16.
3.5
Therefore, the Transmission network requirements for the period FY 2013-14 to FY 2015-16
have to be strategically planned so as to meet the demand growth envisaged. The challenge
for BSEB is be able to put up adequate evacuation facilities for upcoming generation capacity
and augmentation/ replacement of transmission elements to accommodate the bulk power
from internal and external sources without congestion.
Transmission & Distribution (T&D) Losses
3.6
The transmission losses in the system is projected as in the following table

pilfered through unauthorised means. Though, it’s a challenge for Distribution Function to
reduce the losses, the Transmission system has to accommodate the loss component as well
along with legitimate retail sales so far as the transmission infrastructure requirement is
concerned.
Financial health of Power Sector in Bihar
3.9
The erstwhile BSEB has not added much generation capacity since 2002-03. Major portion of
bulk power purchased by two Discoms is from Central Sector Generating Stations and other
sources. Further, T&D loss component is in the range of 40%. Erstwhile BSEB on one hand
buys costly power from spot market in order to try and bridge the demand supply gap, the
higher T&D losses on the other hand lead to insufficient recovery. This restricts erstwhile
BSEBs ability to meet its payment obligations including power purchase bills.
3.10
It has become a challenge to balance the increasing tariff in consumer interest against the
revenue requirement essential for sustainability of the business, which has been bridged
through government support to a certain extent in the past. The approved tariff increase
during past have however remained insufficient to cover the cost that erstwhile BSEB has
incurred and has thus rendered it financially strained.
3.11
From the trend of power purchase costs, it is observed that the costs have risen by almost
double in FY 2011-12 from the FY 2005-06 levels. During the same period, the Average
Billing Rate for the retail categories of consumers has increased only by 87%.

3.12
The increasing loss levels are a major cause of concern as the losses further raise the debt
burden on erstwhile BSEB for meeting its working capital requirements which in turn
increases the interest and finance costs. The recovery of the high losses is not practically
feasible as it will result in huge tariff shock for consumers. Overall the financial health of
BSEB is poor which is a big challenge for all the functions including Transmission.
3.13
With the increasing quantum of power to be transmitted through its existing network, available
margins/ space in the receiving substations and capacity for augmentation are constraints for
further expansion.
Other Key Challenges
3.14
The growth of Transmission Lines and Substations additions over the past few years is
represented in following chart.

Observing the past trend shows that the length of 400 kV Transmission line remained at 75
CKM level, whereas it has grown at minimal 0.4% CAGR for 220 kV and 4.4% CAGR for 132
kV level during five years.
Bihar State Power Holding Company
Page 14
Business Plan for Bihar State Power Transmission Company
3.16
Similarly, the number of 220 kV substations grew at 3% and 132 kV substations increased at
5.65% CAGR during this period. The 220 kV Transformer capacity increased at 8.8% CAGR
and that for 132 kV increased at 13% CAGR.
3.17
Taking into account the tremendous growth that is expected to take place during the ensuing
MYT control period in terms of power availability and retail sales, the Transmission segment
has to cope up by suitably enhancing the growth rate of infrastructure additions and
undertaking appropriate R&M schemes. Thus, keeping pace with the ever increasing power
requirements would be a major business challenge for the Transmission Company during the
ensuing MYT control period.
3.18
The Open Access regulations were issued by BERC in 2006 according to which the eligible
person (Licensee, Generating Company, Consumer etc.) is allowed for non-discriminatory
open access to the intra-state transmission system subject to availability of adequate
transmission capacity. With the growth of the power market, the open access consumers may
put a challenge before the Transco in terms of providing access to transmission facilities.
Transmission Company has to take care of additional capacity that might be required to
accommodate such needs as such open access consumers may not necessarily be existing
customers.
3.19
At execution level, the key challenge for Transmission Company shall be to manage the
multiple clearances related to projects and land – right of way issues efficiently to ensure that
all the schemes are approved and implemented without any time and cost overrun.
3.20
Replacement of ageing assets is necessary to maintain reliability of supply. Further, to
maintain safety and reliability in operation of transmission system, it’s important to improve
the condition monitoring and augment or refurbish the network and control/ switchgear
equipment.
Bihar State Power Holding Company

Business Plan for Bihar State Power Transmission Company
Business Plan for Bihar State Power Transmission Compnay
4.1
The Business Plan for the Transmission Company has been prepared according to the
direction given by the Hon`ble Commission (BERC) in the latest Tariff order for FY 2012-13.
The relevant Para containing the direction is reproduced below for reference:
“The Commission directs the Board or its successor restructured companies to submit the
business plan for generation, transmission and distribution functions separately for a period of
three years, i.e. FY 2013-14 to FY 2015-16 by September, 2012.”
Key Objectives
4.2
Broadly, the following key objectives were kept in mind while preparing the Business Plan.
•
Strategic Planning: The primary objective of the Business Plan is to analyse and
anticipate the future requirements in advance and strategically plan for the capital
investments, related means of financing and various associated costs and document
them which would serve as an effective tool for monitoring and execution of future works.
With the level of economic growth the state of Bihar is experiencing, it becomes utmost
important to project the growth in transmission network infrastructure commensurate with
the energy demand required for fuelling the economic growth targets of the State.
•
Regulatory Compliance: As highlighted in aforesaid Para 4.1, the direction issued by the
Hon`ble commission entails submission of function wise separate Business Plan. Thus it
is an essential part of the regulatory compliance for the Company.
•
Better Operational Efficiency: The Business Plan is prepared so as to be useful for the
Managing Board, associated stakeholders, the Hon’ble Commission and various
government bodies. The future projections in the Plan would help the Transco in decision
making and taking proactive actions, and thus improving the overall operational efficiency
of the transmission network infrastructure.
4.3
In order to meet the growing demand for power by the two distribution companies, its diversity
in terms of geography and evacuating the power expected to be available from upcoming
intra/ inter-state generating stations, Bihar State Power Holding Company (BSPHC) has
prepared a comprehensive business plan to expand the transmission network in the State of
Bihar through various network/ system improvement measures, capacity augmentation and
adding new substations and transmission lines.
4.4
The erstwhile BSEB had signed MoU with some of the upcoming Independent Power Projects
(IPP). Out of these projects, 2x660 MW generation project of Jas infrastructure Capital Pvt.
Limited at Banka is progressing towards commissioning. The necessary evacuation of power
at Banka has been planned in FY 2012-13.
4.5
The Government of Bihar has set up a Special Purpose Vehicle (SPV) to establish three IPPs
under tariff based competitive bidding (Case-2) route, which are also expected to be
th
commissioned is during the 12 plan period.

4.6
Although the implementation of transmission system for evacuation of power from Lakhisarai,
Pirpainti & Buxar generation projects is planned from FY 2016-17, there are associated
schemes for system strengthening at 220 kV and 132 kV voltage levels proposed during the
MYT control period so as to accommodate the projected peak demand on commissioning of
the projects
4.7
In order to draw additional power from the northern part of the Bihar, Transmission system for
evacuation of power from Darbhanga & Motihari 400 kV sub-stations is proposed to be
implemented from FY 2014-15 onwards.
4.8
At number of places of 132/33 kV substations, transformer capacity augmentation is proposed
including Karmanasa, Sonenagar, Pandaul, Chandauti, Hathidah, Lakhisarai, Muzaffarpur,
Ara, Kataiya and Sabour.
4.9
The Transmission lines at Lakhisarai, Jamui, Purnea, Dehri, Sonenagar, and Gaya are either
heavily loaded or old and dilapidated and therefore are required to be strengthened.
Accordingly, planning has been done to re-conductor these lines.
4.10
The Transmission network in the Capital of Bihar is adequate to take care of present level of
demand. However, the future growth in demand necessitates strengthening of transmission
system at 220 kV and 132 kV voltage levels for supplying power to Bihar and surrounding
load centres.
4.11
The proposed Transmission system for Patna city includes 400 kV substations at Bihta,
Gaighat and Fatuha and 220 kV substations Jakkanpur, Mithapur, and Gaighat along with
associated 400-220 kV interconnecting lines.
4.12
Apart from the future planning of the transmission works mentioned above, BSEB has also
planned for immediate removal of existing transmission constraints, to be implemented during
2012-13 at Fatuah, Begusarai, Bodh Gaya, Darbhanga, Gopalganj, Khagaul, Bihta, Sitamarhi,
Ara, Nawadah, Sabour, Naugachia etc.
4.13
The Transco has further provisioned for procurement of critical network equipment viz. Circuit
Breakers, Current Transformers etc. for meeting the medium term needs and procurement of
Emergency Restoration System.
4.14
From the Central Government’s BRGF programme funded by ADB, the BSEB would be
implementing 132/33 kV Grid Substations at Dhanha, Gangwara, and a 220/132 kV Grid
Substation at Pusauli. Under this programme, new 132 kV transmission lines are also
planned.
Proposed Capital Expenditure
4.15
For improvement in the transmission network availability and to strengthen the transmission
network, Transco has planned Capital Expenditure for installation of new transmission lines
Bihar State Power Holding Company
Page 17
Business Plan for Bihar State Power Transmission Company
and substations as well as augmentation and R&M works. The Transco has planned for
Capital Investment of Rs. 6845 Cr. by FY 2016-17, out of which Rs. 3957 Crore is to be
invested during FY 2012-13 up to FY 2015-16. This includes ADB funded new project
schemes worth Rs. 197 Crore and immediate removal of existing Transmission constraints
during FY 2012-13 and FY 2013-14 worth Rs. 310 Crore.
