Open Access
DEFINITION OF “OPEN ACCESS” IN THE ELECTRICITY ACT, 2003
“The 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”
INTRODUCTION
• Open Access is necessary for utilization of short time surpluses.
• Open Access will also create options for distribution companies to buy power.
• Open Access will provide means to the traders/buyers/sellers.
• Non- discriminatory / Transparent Process• Freedom to buy/sell power• Efficient Market Mechanism to address supply /
demand mismatches• Encourage investment in Transmission
Legal Framework
SECTION 38: (CTU Function)
• CTU to provide open access to Licensee or Generating Company on payment of transmission charge
• Any consumer when open access is provided by State Commission on payment of surcharge in addition to transmission charges.
• Surcharge shall be for meeting cross subsidy, and to be progressively reduced and eliminated.
• Surcharge not payable in case of captive generation and Distribution Companies.
• CTU can not engage in generation and trading
Legal Framework
Sections 39, 40 and 41• Similar provisions for STU and Transmission Licensee.• STU can not engage in trading.• Transmission Licensee can not engage in trading
Section 42• State Commission to provide Open Access to all
consumers who required supply more than 1 MW in 5 years.
Agencies involved in Short-Term Open Access Transaction
• RLDC (s)
• SLDC (s)
• CTU

CERC Open Access Regulations, 2008
3. Subject to any other regulations specified by the Commission, the long-term customer shall have first priority for using the inter-State transmission system for the designated use. These Regulations shall apply for utilization of surplus capacity available thereafter on the inter-State transmission system by virtue of-
(a) Inherent design margins;
(b) Margins available due to variations in power flows;
(c ) Margins available due to in-built spare transmission capacity created to cater to future load
growth or generation addition:
CERC Open Access Regulations, 2008
• Effective 01.04.2008
• Regulations cover only Short-term Open Access
• Transactions categorized as Bilateral and Collective (through PX)
• Earlier Products of Short-Term retained under Bilateral Transactions
• Nodal Agency
– Bilateral : RLDCs
– Collective : NLDC
• Both Buyers and Sellers of Collective transactions to bear transmission charges and absorb transmission losses
• Inter-Regional links -No Separate treatment.
• Emphasis on “Scheduling” rather than “Reservation”
• SLDC consent mandated along with application
• In case of Congestion – e-Bidding without Price Cap
• Exit Option provided with payment of up to 2 days open access charges.
• Moving towards empowerment of SLDCs

Open Access- Way Ahead…
• Presently CERC has allowed only Day ahead Market
• At present CERC has allowed only National level
operated Power exchanges. In due course if need
arises Regional level operated exchanges will come.
• In power exchanges, as per CERC norms the price
discovery is through Double sided closed auction.
• Collective transaction means a set of transactions
discovered in power exchange through anonymous,
simultaneous competitive bidding by buyers and
sellers
• For Power Exchange transactions the Nodal agency
will be National Load Despatch Centre (NLDC).
Open Access- Way Ahead…• The ATC declaration is to be done by NLDC on its web
site every day.
• Depending on the corridor availabilities the solution is to be found out and the allowed trades will be intimated to NLDC.
• If there is no congestion NLDC will accept the trades and issue the schedules to the power exchange and the same will be implemented in RLDC schedules.
• In Power Exchange transactions both buyer and seller have to pay the Transmission and operating charges separately.
• The transmission losses also have to be borne by the buyer and seller separately.
