2. The Power Sector in India has undergone a plethora of reforms in
the last two decades.
Introduction of competition has been one of the main aims of reform
in the electricity sector in India.
One of the most important steps taken towards achieving this was
the introduction of open access in the Electricity Act, 2003, where
large consumers have access to the Transmission and Distribution
(T&D) network to obtain electricity from suppliers other than the
local electricity distribution company (DISCOM).
INTRODUCTION
OBJECTIVE
The objective of open access was to provide opportunity to energy
intensive industry and commercial establishments to source
electricity directly from the market and manage costs to remain
competitive.
Open Access was to also improve the economic health of the
Distribution Licensees by reducing power procurement at higher
marginal cost so that the non-open access retail consumers of the
Distribution Licensees would not get unduly burdened.
3. Electricity Act 2003 (sub-section 2 of section 42) lay down provisions for
a power market and competition wherein electricity consumers now
have the right to procure power from the supplier of their choice other
than their distribution company.
For example, under open-access a consumer in Telangana has right to
select the source of supply form any generator. This generator may be
generating power in Telangana or any other state in India.
Open Access, as per Electricity Act 2003
“Non-discriminatory provision for the use of transmission lines or
distribution system or 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”.
Open Access allows large and heavy users of powers i.e. those with 1
megawatt (MW) and above connected load to buy cheaper power from
the open market.
The idea is that the customers now able to choose from a number of
competing power companies like GENCOs, CPSU, IPPs, Private.
Licensees, Excess Captive from captive power plants instead of being
forced to buy electricity from their existing electric utility monopoly.
OA WITH EA 2003
4. 1. Competitive Pricing
Open Access was introduced in the Electricity Act to bring in
competition into the sector, thereby benefitting the end consumer.
Over the years, it has acted as a catalyst in bringing reforms into the
sector by benefitting the players across the spectrum of value-chain
from generators to suppliers to electricity traders to the end
consumers.
Open Access will ease the power shortage since a number of power
producers like Solar energy companies can now transmit power from
their solar parks to different load centers.
Once the consumers are given the choice to purchase power from
the open market, it will automatically lead to competitive pricing of
electricity making electricity cost go down.
2. Regular electricity supply
It helps the industrial & commercial consumers by ensuring regular
electricity supply at competitive rates.
It helps large consumers particularly the sick textile, cement and
steel industrial units by ensuring regular supply of electricity at
competitive rates and boost business of power bourses.
PROS AND CONS OF OPEN ACCESS
5. 3. Help Consumers to meet RPOs
It also enhances the business of power markets as the open access
helps consumers meet their Renewable Purchase Obligations (RPOs) as
well.
4. Exposure to Grid Risks
In open access, eligible consumer can avail the benefits of cheaper
green solar power by either purchasing through the rooftop solar
installation in its premises or buying from an offsite solar farm.
While open access does away with limitations of rooftop solar such as
scalability and high capital expenditure, it is often exposed to
unpredictable grid risks.
5. Appropriate utilization of existing infrastructure (T&D)
Existing Transmission and Distribution Infrastructure can be used to
avail the open access.
In open access, this will enable number of players utilizing these
infrastructure and transmit power from generation to the load center.
This will mean utilization of existing infrastructure and easing of power
shortage.
Trading, now a licensed activity and regulated will also help in
innovative pricing which will lead to competition resulting in lowering of
tariffs.
PROS AND CONS OF OPEN ACCESS
6. Open Access, rights governed in India by Electricity Act 2003, can
be classified as under on the basis of location of the purchasing and
selling entities:
Types of Open Access Users
1. Intra State (With in the state)
2. Inter State (State to State)
Intra State Users
1. Short Term (STOA) up to 1 year
2. Medium Term (MTOA) - AP & TS Not Contemplated
3. Long Term (LTOA) 2 years and above
Inter State Users
1. Short Term (STOA) – Maximum one month.
2. Medium Term (MTOA) – 3 months to 5 Years (earlier 3 Years)
3. Long Term (LTOA) – 12 Years to 25 Years
Power Markets- Collective Transactions
1. Indian Energy Exchange Limited – IEX
2. Power Exchange India Limited – PXI
Minimum Open access allowed for 1MW
OPEN ACCESS CLASIFICATION
7. When the Purchasing and selling entities belong to same state then
it is called as an Intra-state transaction. In this case, the open
access charges comprising Transmission Losses and Charges
Wheeling losses and Charges (if applicable) and cross-subsidy of
that particular state are applicable.
In Intra-State Open Access State Electricity Regulatory Commission
(SERC) regulations are followed.
Wherein purchase rights can be categorized.
Duration of which depends on the respective state open access
regulations.
Intra State Purchases for DISCOMs
1. Short Term (STPP) up to 1 year
2. Medium Term (MTOA) AP & TS Not Contemplated
3. Long Term (LTTSA) with GENCO 2 years and above
4. Long Term (LTOA) with Other Generators 2 years and above
Intra State OA Users
1. Short Term (STOA) up to 1 year
2. Medium Term (MTOA) - AP & TS Not Contemplated
3. Long Term (LTOA) 2 years and above
INTRA STATE OPEN ACCESS
8. When the Purchasing and selling entities belong to different states
then it is called as an Inter-state transaction.
In this case, apart from the open access charges applicable in intra-
state transactions, Point-of-Connection (POC) charges and losses of
the regional grids where the buyer and seller are located are also
applicable.
In Inter State Open Access Central Electricity Regulatory
Commission (CERC) regulations are to be followed
Inter State Open Access
1. Short Term Open Access (STBC): Open Access allowed for the
period of less than one month.
Bilateral: Power Purchase Agreement (PPA) is a contract between
the seller and the consumer. POSOCO is the Coordinator.
Collective: Traded through Power Exchanges by Exchange
Members/Traders.
2. Medium Term Open Access (MTOA): Open Access allowed for a
period of 3 months to 5 years. (earlier 3 Years)
3. Long Term Open Access (LTOA): Open Access allowed for a
period of 12 years to 25 years.
INTER STATE OPEN ACCESS
9. Renewable Energy based transactions under intra-state open-
access is more convenient than inter-state open-access.
in order to promote Renewable Energy, many state provide
various concessional provisions like concessional Wheeling
and Transmission charges, Banking facility benefits,
Electricity Tax / Duty Exemptions, Waiver or Discount in
Cross-Subsidy-Charges etc.
These concessional provisions reduce the cost of transaction
significantly and allow RE generators to offer better
commercial terms to consumers.
INTRA VS INTER OPEN ACCESS
10. OPEN ACCESS CHARGES
Electricity consumers can make use of the existing Transmission and
Distribution infrastructure after paying appropriate charges determined by
their respective State Electricity Regulatory Commissions (SERCs).
A supportive regulatory regime from the state electricity authorities
combined with better grid stability can make long-term open access projects
viable.
These changes will facilitate more projects from the renewable energy
companies who are taking huge upfront risks at present and will definitely
upgrade the state of power trading in the country.
These charges against the usage of Transmission and Distribution
infrastructure can vary from state to state and are lesser in states with
stable grid and favorable regulatory regime.
In case of solar power, the state-wise open access charges can vary from as
low as Rs. 0.2/KWh to Rs.1.5/KWh.
There are several charges to be paid by Open Access Consumers to
Distribution Licensee, Transmission Licensees and other related entities,
other than the power purchase cost paid to the generator or supplying
entity.
Apart from below charges the open access consumers has also to fulfill the
renewable purchase obligation (RPO), in which they have to purchase a part
of their total consumption through electricity generated from renewable
energy.
11. OPEN ACCESS CHARGES
Connectivity Charges (at the time of Application)
Point of Connection (PoC) Charges (CTU)
Transmission Charges (STU)
Transmission Losses
Wheeling Charges (DISCOM)
Wheeling Losses
Cross Subsidy Surcharge (DISCOM)
RLDC Charges (POSOCO)
SLDC Charges.
In case of AP & TS SLDC Charges Bifurcated as
SLDC Operating Charges
SLDC Annual Fee.
12. OPEN ACCESS
The Buyer and Seller of Electricity can opt for
either Collective or Bilateral Transactions.
Besides minor changes in the meter installed, Open
Access transactions are essentially managed through
energy accounting at the state level.
EBC established under Control of SLDC for Energy
Accounting.
Thus, a Consumer buying Power from Open Access
will see the transaction accounted for in its monthly
bill.
13. COLLECTIVE TRANSACTIONS
In case of Collective Transactions the Electricity is
traded through Power Exchanges by Exchange
Members/Traders for a very small margin fixed by
commission.
Power Exchange transactions are transactions carried
out over an electronic platform.
Currently India has two operating Power Exchanges
(PXs)
1. Indian Energy Exchange (IEX) and
2. Power Exchange India (PXI).
At Power Exchanges Consumers can buy/sell electricity
on day-ahead/week-ahead basis or for particular time
period in a day.
Buyer/Seller will be bidding for electricity cost for
particular time period and for each time period price at
which electricity is determined by market.
14. BILATERAL TRANSACTIONS
Power Purchase Agreement (PPA) is a contract
between the Seller and the Consumer for buying
power at mutually agreed tariff for a predetermined
number of years.
The PPA defines all of the commercial terms for the
sale of electricity between the two parties, including
when the project will begin commercial operation,
schedule for delivery of electricity, penalties for under
delivery, payment terms, and termination clauses.
A significant quantum of power is still traded through
bilateral transactions.
Many of the leading solar players under the OPEX
model in India are resorting to bilateral agreements for
tariff determination with commercial and industrial
clients.
15. BILATERAL VS COLLECTIVE
Adopting a combination of Bilateral transaction and
Collective transaction may result in cost savings of
sourced energy and long term energy security because
bilateral mode of transaction brings volumetric and
price certainty for a relatively longer duration while
sourcing power from Power Exchanges provides
advantages such as better price discovery, risk
mitigation from counter-party default.
