  1. Open Access

  2. 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”

  3. 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

  4. 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

  5. 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.

  6. Agencies involved in Short-Term Open Access Transaction • RLDC (s) • SLDC (s) • CTU • STU (s) • Buyer • Seller • Trader

  7. Open Access – CERC Regulations, 2008

  8. 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:

  9. 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

  10. 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 in ISTS: CERC OA Regulations 2008

  27. Time Line for Advance Scheduling M1 M0 M2 M3 10 5 5 Processing time for RLDCs Last Day for submission of Applications for transactions in M1, M2, M3

  28. e-Bidding Procedure • Invitation of Bids • period of congestion • RTS/IR corridor – overstressed • Only Registered Users • User ID & Password • Electronic submission – website of CTU • Bid Closing time as specified • Single Price Bid • No Modification/withdrawal once submitted • Bid Price - in addition to Open Access Transmission Charges • Multiples of Rs. 10/ MWh . ( Min. Rs. 10/MWh) • Mandatory - Non-participation – Rejection of Application • Acceptance - Decreasing order of Price Quoted • Equal Price Bids – Pro-rata • Part Acceptance – Price as quoted by the bidder • Full Acceptance – Price quoted by last bidder getting full acceptance

  32. INCORPORATION IN DAILY SCHEDULES • RLDCs to incorporate in Daily Schedules of the Regional Entities • Average energy losses -estimated on weekly basis • RLDCs – ISTS • SLDC – intra-State TS • resolution of 0.01 MW at each State/inter-Regional boundaries. • ramp-up • at the time of commencement of the transaction • ramp-down • at the time of termination of the transaction

  34. Example: • Approved transaction : 1st to 30th of a month • schedule :100 MW : 0000-2400 (2400 MWh/ day) • Revision Request submitted on 12th • Requested schedule : 15th to 30th 50MW (1200 MWh/day) • Revised from : 15th to 30th • Charges : 2400 MWh/ day for 15th &16th 1200 MWh/day from 17th to 30th

  35. CURTAILMENT IN CASE OF TRANSMISSION CONSTRAINTS • Allocation/Reallocation of ISGS power • Transmission constraint or to maintain grid security • curtailed in the manner, which in the opinion of RLDC, would relieve transmission constraints/ enhance grid security • Open Access Bilateral Transactions would generally be curtailed first followed by the Collective Transactions • Rerouting allowed without curtailment • Pro-rata refund of Transmission Charges

  36. COMMERCIAL CONDITIONS • All Payment related to Open Access Charges • by Applicant to the Nodal RLDC • within three working days from the date of acceptance • Application Fees (as per Para 7 of Regulation) • non-refundable fee of Rupees five thousand (Rs.5000/-) only • Transmission charges (Para 16 of Regulation) • Intra-region (Rs.80/MWh) • Adjacent Region (Rs. 160/MWh) • More than two regions (Rs.240/MWh) • STS charges – as specified by respective SERCs or Rs. 80/MWh • Operating charges (as per Para 17 of Regulation) • Rs. 2000/- per day each RLDCs/SLDCs involved

  37. DEFAULT IN PAYMENT OF OPEN ACCESS CHARGES • Nodal RLDC, at its discretion • may not schedule the transaction or • may cancel the scheduling of already scheduled transaction or • may not entertain any Application of such Applicant in future until such time the default is cured. • simple interest at the rate of 0.04 % for each day of default from the Due Date of Payment • Cheque has been dishonored • No cheque payment - next three (3) months

  45. UI vs STOA market (All regions) 100% power market 92% long term market 5% UI market 3% STOA market

  46. Open Access Applications Processed (Since Beginning) > 20,000 No. Volume (Approved Energy) (Since Beginning) > 90BUs Applications Approved > 95 % Refusal/Non-consent by SLDCs > 3 - 4% Refusal due to system constraints < 0.5 %

  47. Open Access Transactions between extreme corners of the country RGCCPP ( Kayamkulam) to PSEB Arunachal Pradesh(NER) to PSEB TNEB to J&K Large number of Captive Generating plants used STOA and helped in enhancing the power availability in grid. Ugar Sugars (KAR) - JAIPUR (RAJASTHAN) Godavari Sugars (KAR) - MSEDCL NCS Sugar(ANDHARA) – GUVNL Indorama ( MAH) – APPCC ( ANDHRA)

  48. Open Access Even costly power was harnessed to meet the high demand RGCCPP ( Kayamkulam) (NAPTHA) to PSEB BSES(KERALA) (DIESEL) to NDMC (DELHI) Diversity being gainfully utilised by Market players under STOA Delhi/TNEB Export in night ; Import during evening peak ANDHRA Export during evening peak ; Import in night Generators PLF has also increased. Kayamkulam GPS - (From 57 % in 2006-07 to 82 % in 2007-08- 82%)

  49. 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).
