A detailed presentation about the Captive power Policy.

1. Captive Power Policy
Issues, Regulations and Concerns
Priyank Jain

2. • Captive power today is significant source of power
for the Indian economy, which plays an important
role in the present power scenario being
characterised by inadequate supply of power, poor
and unreliable power quality, and high tariffs
resulted due to heavy cross-subsidization. There is
paradigm shift in usage pattern of captive power
plants from back-up use to baseload use.
• Presently the captive power plants capacity
accounts for nearly one-fifth of the total installed
capacity. With liberalisation of economy and
technological developments many options are
available for captive structuring.

3. • The Electricity Act 2003 has
legislatively facilitated setting up &
operation of captive power plants.
Other policies such as the National
Electricity Policy 2005, the National
Tariff Policy 2006, the Captive Power
Policy (draft) and various state policies
contains the clauses relevant to
encourage the development of captive
power plants in India.

4. • Six states – Gujarat, Orissa, Andhra Pradesh, Madhya
Pradesh, Karnataka and Tamil Nadu – account for
almost two-thirds of the captive capacity. Other
significant contributors include Bihar, Maharashtra and
Uttar Pradesh.
• For the industries that use energy intensively, the energy
is the critical component of the total production cost.
• The engineering, chemical and mineral/metal industries
account for almost two-thirds of the total installed
capacity in the captive segment. Other industries include
cement, textiles and sugar.

5. • The captive generator has a number of fuel
options today. The choice could be between oil,
natural gas, naphtha, bagasse or coal.There are
also options like wind and hydro.
• Availability of open access is the major issue
related to the selling of power to grid by captive
power plants.
• Other issues are related to the strengthening of
intra-state and inter-state transmission network,
reasonable tariff and availability of available
additional fuel required by the captive power
plants.

6. • Installation of captive power plants in
future is likely to grow at a higher rate
compared to the current rate of growth.
The promise for future growth of captive power
plants lies with the renewable sources of energy.
Fossil fuels are limited and have adverse
environmental impact. Captive demand,
therefore, provides an attractive ‘niche’ for
renewable energy to be deployed in industry.

7. Some features:
• Captive Power refers to generation from a unit set up
by industry for its exclusive consumption.
• Captive power plants are essentially non utility power
plants.
• These power plants are owned by specific industries
which consume all the power produced for its
production purposes.
• The size of these power plants varies. These power
plants can be as small as 0.2 MW or can be as big as
300 MW.

8. The major factors responsible for the soaring growth of the
captive power plants are, as follows:
– Non-availability of adequate grid supply
– Poor quality and reliability of grid supply
– High tariff as a result of heavy cross
subsidisation

9. The Advantages
– Captive power plant is close to the load centre and
hence reduction in the fixed cost of electricity generated
due to lesser stranded assets
– Reduced transmission and distribution losses
– Grid is strengthened at multiple points, even at the tail-
ends.
– Higher thermal efficiency, due to waste heat recovery
by method of cogeneration
– Distribution of environmental impact
– Shorter gestation period to set up power plants
– Captive power plants have modular designs and hence
can match the load profile

10. Concern for state electricity boards on account of following
reasons:
Captive plants may have adverse impacts on the finances of
the utility, such as:
– Industrial load is the main source for cross-subsidising
revenue flows
– Billing and collection is much more efficient for HT consumers
– State electricity board’s ability to service escrow accounts for
security packages is also reduced
– Non-optimal growth of the sector
– Problems in grid management especially in case of states
with surplus power
– Adverse environmental impacts arising from types of fuels
used and from higher emissions per unit of production, as
compared to large power plants
– Reliability of power supply from captive and cogeneration
plants as a source of firm power

11. Concern of the owners of captive power plants
stems from:
– Non-remunerative tariff structure for surplus power
produced by them
– No risk sharing in case of non availability of fuel,
change in variable cost due to switching of fuel after
entering into power purchase agreement (PPA), etc
– Inadequacies in wheeling and banking facilities
– High contract demand charges
– High level of duties and taxes on sale of power
– High wheeling losses assumed for power to be sold
to grid by captive power plant
– Need to devote time and energy to an activity, which
is not their core business
– Restrictions on the minimum amount of power to be
wheeled
– If the captive power plant fails, charges for back-up or
standby power from the grid are generally twice the
normal rate for captive plants

12. Captive power plant has been defined
under the Electricity Act-2003 as
• “…a power plant set up by any person to
generate electricity primarily for his own
use and includes a power plant set up by
any co-operative society or association of
persons for generating electricity primarily
for use of members of such cooperative
society or association”.

13. • Provisions of the Electricity Act 2003 and Electricity Rules 2005
• The Electricity Act 2003 has legislatively facilitated setting up & operation of captive power
plants, which mandates the following:
• According to Section 2(8) of the Act
• “Captive Generating Plant” has been defined as a power plant set up by any person to generate
electricity primarily for his use and includes a power plant set up by co-operative society or
association of persons for generating electricity primarily for use of members of such co-operative
society or association.
• Section 9 of the Act Mandates that:
• 9. Captive generation. - (1) Notwithstanding anything contained in this Act, a person may
construct, maintain or operate a captive generating plant and dedicated transmission lines:
• Provided that the supply of electricity from the captive generating plant through the grid shall be
regulated in the same manner as the generating station of a generating company.
• (2) Every person, who has constructed a captive generating plant and maintains and operates
such plant, shall have the right to open access for the purposes of carrying electricity from his
captive generating plant to the destination of his use:
• Provided that such open access shall be subject to availability of adequate transmission facility
and such availability of transmission facility shall be determined by the Central Transmission
Utility or the State Transmission Utility, as the case may be:
• Provided further that any dispute regarding the availability of transmission facility shall be
adjudicated upon by the Appropriate Commission.”

14. Section 40 of the Act mandates that:
• 40. Duties of transmission licensees. -
• ………………………………………………..
• Provided also that such surcharge shall not be
leviable in case open access is provided to a
person who has established a captive
generating plant for carrying the electricity to the
destination of his own use.

15. 42. Duties of distribution licensee and open access. –
• Provided also that such surcharge shall not be leviable in case open
access is provided to a person who has established a captive
generating plant for carrying the electricity to the destination of his
own use.
• A CPP connected with the grid acquires the status of a generating
company under the provisions of Section 9 of the Act and is thus
required to fulfill obligation of the generating company as contained
in the Act and rules/regulations framed thereunder. Section 10(2) of
the Act states that a generating company may supply electricity to
any licensee in accordance with the Act and rules & regulations
made thereunder and also to any consumer under open access
subject to proviso of Section 42(2) of the Act.

16. • Section 62 of the Act outlines that an
appropriate commission shall determine
the tariff of supply affected by a generating
company to the distribution licensee. This
section applies to such sale by CPP also.
Thus, it will also cover the contingency of
procurement and purchase of power on
day to day basis for meeting short term
requirement to meet shortages.

17. The relevant clause of the Electricity Act 2003 is given
as under:
• 62. Determination of tariff. - (1) The Appropriate Commission shall
determine the tariff in accordance with provisions of this Act for –
• (a) Supply of electricity by a generating company to a
distribution licensee:
• Provided that the Appropriate Commission may, in case of
shortage of supply of electricity, fix the minimum and maximum
ceiling of tariff for sale or purchase of electricity in pursuance of an
agreement, entered into between a generating company and a
licensee or between licensees, for a period not exceeding one year
to ensure reasonable prices of electricity;
• (b) Transmission of electricity;
• (c) Wheeling of electricity;
• (d) Retail sale of electricity.

18. Determination of tariff as per
Electricity Act contd.
• Provided that in case of distribution of electricity in the same area by
two or more distribution licensees, the Appropriate Commission
may, for promoting competition among distribution licensees, fix only
maximum ceiling of tariff for retail sale of electricity.”
• The Electricity Act mandates that an appropriate commission in case
of shortage of supply of electricity can also fix minimum and
maximum ceiling of tariff for sale or purchase of electricity.
• It is obligatory on part of a Captive Power Plant to get its tariff
determined for its sale of power to distribution licensee and for a
distribution licensee to enter in an agreement for power purchases
of power at the tariff determined by the Commission.
• It has been clarified under Electricity Rules 2005 issued by the
Government of India on dated 8.6.2005 that the captive
generating plant shall be qualified as such if not less than 26%
of the ownership is held by the captive user(s) and not less
than 51% of the aggregate electricity generated is consumed
for captive use.

19. • Provisions of the National Electricity Policy
• In the National Electricity Policy notified by the Government of India, it has
been stated that the liberal provisions for setting up CPPs have been made
in order to secure a cost effective quality power thereby generating
employment opportunities mandating a speedy and efficient growth of the
industry. The appropriate commissions shall determine the tariff of the
supply when a licensee takes power from a Captive Power Plant. The
relevant para of NEP reads as under:
• 5.2.2 The Government of India has initiated several reform measures to
create a favorable environment for addition of new generating capacity in
the country. The Electricity Act 2003 has put in place a highly liberal
framework for generation. There is no requirement of licensing for
generation. The requirement of techno-economic clearance of CEA for
thermal generation project is no longer there. For hydroelectric generation
also, the limit of capital expenditure, above which concurrence of CEA is
required, would be raised suitably from the present level. Captive
generation has been freed from all controls.

20. • 5.7.1 (c) Captive generating plants should be
permitted to sell electricity to licensees and
consumers when they are allowed open access
by SERCs under section 42 of the Act.
• 5.2.24 The liberal provision in the Electricity Act,
2003 with respect to setting up of captive power
plant has been made with a view to not only
securing reliable, quality and cost effective
power but also to facilitate creation of
employment opportunities through speedy and
efficient growth of industry.

21. Provisions of Group Captives as
per Electricity Act 2003
• 5.2.25 The provision relating to captive power
plants to be set up by group of consumers is
primarily aimed at enabling small and medium
industries or other consumers that may not
individually be in a position to set up plant of
optimal size in a cost effective manner. It needs
to be noted that efficient expansion of small and
medium industries across the country would
lead to creation of enormous employment
opportunities.

22. Surplus Power of Captives
• 5.2.26 A large number of captive and standby generating
stations in India have surplus capacity that could be
supplied to the grid continuously or during certain time
periods. These plants offer a sizeable and potentially
competitive capacity that could be harnessed for meeting
demand for power. Under the Act, captive generators
have access to licensees and would get access to
consumers who are allowed open access. Grid inter-
connections for captive generators shall be facilitated as
per section 30 of the Act. This should be done on priority
basis to enable captive generation to become available
as distributed generation along the grid.

23. Role of Non-Conventional Energy Sources
• Towards this end, non-conventional energy sources
including co-generation could also play a role.
Appropriate commercial arrangements would need to be
instituted between licensees and the captive generators
for harnessing of spare capacity energy from captive
power plants.
• The appropriate Regulatory Commission shall exercise
regulatory oversight on such commercial arrangements
between captive generators and licensees and
determine tariffs when a licensee is the off-taker of
power from captive plant.

24. • Provisions of the National Tariff Policy:
• In pursuance to section 3 of the Act, the Central
Government has notified on 6.01.06 the tariff policy,
which among others has also emphasized the need for
harnessing the Captive generation. The salient features
of which are as under:
• 5.4 While it is recognized that the State Governments
have the right to impose duties, taxes, cess on sale or
consumption of electricity, these could potentially distort
competition and optimal use of resources especially if
such levies are used selectively and on a non- uniform
basis.

25. • In some cases, the duties etc. on consumption of
electricity is linked to sources of generation (like captive
generation) and the level of duties levied is much higher
as compared to that being levied on the same category
of consumers who draw power from grid. Such a
distinction is invidious and inappropriate.
• The sole purpose of freely allowing captive generation is
to enable industries to access reliable, quality and cost
effective power. Particularly, the provisions relating to
captive power plants which can be set up by group of
consumers has been brought in recognition of the fact
that efficient expansion of small and medium industries
across the country will lead to faster economic growth
and creation of larger employment opportunities.

26. • For realizing the goal of making available
electricity to consumers at reasonable and
competitive prices, it is necessary that
such duties are kept at reasonable level.

27. Tariff structuring and associated issues
• (1) A two-part tariff structure should be adopted
for all long term contracts to facilitate Merit Order
dispatch.
• According to National Electricity Policy, the
Availability Based Tariff (ABT) is to be
introduced at State level by April 2006. This
framework would be extended to generating
stations (including grid connected captive plants
of capacities as determined by the SERC). The
Appropriate Commission may also introduce
differential rates of fixed charges for peak and
off peak hours for better management of load.

28. LIMITATIONS
– Transaction of power between CPP and grid depends
on availability of open access. Thus the issues related
to open access are
» The State Regulatory Commissions which have not
issued the regulations for open access may have to
expedite the process.
» The State Regulators may be urged to develop
progressive and encouraging policies for CPP (like
one issued by MERC)
» No electricity duty should be imposed on self
consumption of electricity generated by Captive
Power Plants of a industry. Reasonable duty may
be imposed for sale of power.

29. Limitations
» Reduction in contract demand of a CPP holder with
distribution licensee may be allowed without any penalty.
» CPPs which are parallel with the grid, standby demand
charges should be reasonable. However, if the CPP
exceeds the Contract standby Demand then reasonable
penal rate should be applicable on excess drawl.
» High wheeling charges & losses make open access
unviable.As captive surplus would be sold within a limited
area, wheeling charges / losses should be applied for the
particular area rather than average grid charge / losses.
» Wheeling charges for transfer of surplus power may not
exceed 7% of the generation cost within the state.

30. Limitations
» The cross subsidy surcharge applicable on HT
consumers opting to purchase surplus power from
CPPs must be reasonable. This may be fixed in
accordance with avoided cost method suggested by
FOIR (Forum of Indian Regulators).
» For the purpose of recovery of T&D losses in OA
charges, the losses should be benchmarked to
reflect technical losses, gradually reduced and
equitably distributed. Gradually recovery of
commercial losses needs to be reduced
» Parallel Operation Charges (POC) imposed by state
utility is very high. Aligning of POC with ABT regime
would encourage connectivity to grid for facilitating
transfer of surplus power to the licensee.

31. Limitations
» Banking of energy may be allowed by the distribution
licensee and shall be regulated by the energy banking
agreement.
» For Continuous Process Industry round the clock banking
should be permitted with a rider that energy banked at
night should be drawn during the night hours only.
» For the present, 0. 5 class metering arrangement may be
allowed. 0.2 class accuracy metering arrangement as
required as metering regulations may be installed in
phases.
» Imposition of cess on captive power generation.
– Strengthening of intra-state and inter-state transmission
network.
– Fixation of reasonable tariff by State Regulatory Commission
for the surplus power available from the CPPs.
• To make available additional fuel required by the CPPs.
