Background Power is a commodity which cannot be stored. It has to be utilised as and when it is produced. Power is generated by the generating stations, transported through the transmission lines, and supplied to the end user by the distribution system. As power cannot be stored, efforts have to be made for the efficient utilisation of the power system and bridge the surplus-deficit gap. Thus, the concept of sale and purchase of power through various modes came into existence.
Terminology Power is measured in Watt. One Unit of power constitutes 1000 Watts supplied for One Hour. This constitutes to 1 kWH (One Kilo Watt Hour). One Mega Watt (MW) = 1000 kW It is also often referred in terms of Million Units (MUs) = 10,00,000 units.
What is Open Access? The Electricity Act 2003 defines open access as follows: " Open access means 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.''
Surplus power of State Generating Companies. Surplus power of State Power Utilities of the State and other Distribution Licensees. Sale of Unallocated / Surrendered Power of Central Sector Generating Companies. Un-requisitioned power of CSGS. Merchandise Power Plants. Captive Power Plants for their own use. Surplus power of CPPs (Captive or Co-gen)/ IPPs. Collective transactions through exchange. Purchase of power by a consumer. Renewable power with limitation on scheduling. Open Access can be granted in case of-
Salient Features of Open Access Commercial mechanism for transmission pricing for long, medium and short term open access including UI and transactions through exchange. Approval of open access for the desired quantum and period of supply. Non-discriminatory open access. Freedom for scheduling of power. Freedom to revise the open access or cancellation thereof. Policies could be different for ‘Advance Scheduling’, ‘Day-ahead Scheduling’ or ‘Booking of Open access’, as the case may be. Freedom to market that could boost the growth. Appropriate settlement mechanism.
Electricity Act - 2003 It was framed in the wake of: Growing Power needs Continuous Surplus-Shortage conditions faced in various parts of the country.
Types of Open Access Long Term Open Access. (LTOA) [3 to 12 years] Medium Term Open Access. (MTOA) [3 months to 3 years] Short Term Open Access. (STOA) [up to 3 months]
Present Market at a Glance Long Term Market Above 3 years Short Term Open Access Bilateral Transaction Collective Transaction Day Ahead Transaction Contingency Transaction 3 month ahead Day Ahead ahead After Clearance of PX On the day of operation Schedules Balancing Market ( UI ) ( Real Time Operation ) Medium Term Market 3months-3Years
Governing Bodies State Load Dispatch Centers (SLDC) Regional Load Dispatch Centers (RLDC) National Load Dispatch Center (NLDC) State Electricity Regulatory Commissions (SERC) Central Electricity Regulatory Commission (CERC) Regional Power Committee (RPC) Regional Energy Authority (REA) Central Energy Authority (CEA) Power Ministry, Govt. of India
Regulatory Commissions The Regulatory Commission remains the most important organization in the electricity sector after the enactment of the Electricity Act,2003.The new law distances Government from regulation and transfers all regulatory responsibilities to independent Regulatory Commissions. The Regulatory Commissions are omnipresent across the wide range of activities envisaged for the sector. They have the powers to fix tariff, grant license, regulate the performance of the licensees, adjudicate upon disputes, regulate the phasing out of Open Access in distribution and determine Open access surcharge etc.
Procedure for Bilateral Transactions There are two types of procedures of bilateral transactions viz. : Procedure for Individual bilateral transactions (Other than Power Exchanges) Procedure for Collective Bilateral transactions (for Power Exchanges)
OPEN ACCESS CHARGES Charges in case of complete or partial approval Transmission Charges (as determined by CERC) Wheeling Charges (as determined by CERC) Imbalance (UI) Charges Reactive Energy Charges Surcharge Interconnection Charges Connectivity Charges Operating Charges (SLDC charges) Charges irrespective of whether approval is granted or not Application Process fees of respective RLDCs and SLDCs (if any)
Commercial Conditions for Bilateral Transaction The Transmission charges for the use of the inter-State network shall be in Rs./MWh depending upon the type of transaction and shall be payable by the short-term customer for the energy approved at the point or points of injection. The rate for transmission charges shall be as follows: Type of TransactionTransmission Charges (Total) Rs/MWh (a) Bilateral, intra-regional 80 (b) Bilateral, between adjacent region 160 (c) Bilateral, wheeling through one or more region 240 (d) Collective transaction charges 100
Commercial Conditions for Bilateral Transaction The following commercial conditions shall apply for the Bilateral Transaction: TERMS OF PAYMENT All payments associated with Bilateral Transaction shall be made by the applicant to the Nodal RLDC. The applicant shall make following payment to the Nodal RLDC within three working days from the date of acceptance of Bilateral Transactions.

Financial Settlements (Transmission Charges) Payments of Transmission charges and Operating Charges shall be made by the Power Exchanges to the NLDC, by next working day falling after the day on which the Application was processed at NLDC. The Transmission charges for the use of intra- State transmission system and Operating Charges for the SLDCs shall be directly settled by the Power Exchange (s) with the respective SLDC.
Submission of Open Access Application 1. An open access customer or the power exchange (on behalf of buyers and sellers) intending to avail of open access for use of the transmission lines or associated facilities for such lines on the inter-State transmission system, shall make an application to the nodal agency in accordance with these regulations. 2. The application for a bilateral transaction shall contain the details, such as names and location of supplier and buyer, contracted power (MW) to be scheduled and interface at which it is referred to, point of injection, point of drawl, starting time block and date, ending time block and date, and such other information that may be required in the detailed procedure. 3.
