4. 4 Market Development is the responsibility of the Electricity Regulators (Sec 66, 178 IE Act, 2003). Sec 174: The ACT is overriding Preventing market domination is the responsibility of the Regulators (Sec 60, IE Act, 2003). Mandate for developing a Power Exchange given to CERC in the National Electricity Policy. Statutory Provisions

5. 5 Most of the supplies are tied up in long term PPAs: Mostly, regulated two-part tariff: Ideal for investment promotion as well as price security for Discoms Short term trading constitutes 2 to 3% of the total supply. Trading essentially between surplus & deficit distribution utilities. Trading is essential for resource optimisation and meeting short term peak demand and for disposing off surpluses which are inevitable as a utility has no direct control over consumer load . Current Scenario

6. 6 ALL INDIA POWER SUPPLY SCENARIO(April, 2005 - March, 2006)

7. 7 Open Access Regulations have facilitated power trading in an orderly manner. Energy agreements and transmission clearance have to be arranged separately. Open Access charges are reasonable and simple to apply. Current Scenario

8. 8 Short-term Trading Volume

9. 9 Suppliers call for bids from buyers/traders. Traders compete to win the supply bids. Buyers have no option but to buy from the trader having the supply contract. Due to deficit scenario, suppliers dominate. Prices of trades electricity have been going up. Most of the bilateral trading is inter-regional; - ER, NER are suppliers - NR, WR are buyers Current Scenario

10. 10 Price trend of traded electricity

11. 11 Need to curb sellers’ domination Need to put on end to profiteering Need to organize short term trading on a transparent, equitable and efficient platform Need to increase the supplies Need to bring surplus captive generation into the grid. Need to encourage peaking power plants and merchant generation. For optimum resource management, need to simultaneously clear energy contracts & transmission paths. Current Scenario

12. 12 Adequate Inter-state transmission system, but needs strengthening Established scheduling, dispatch and energy accounting procedures UI accounting system for real time deviations from schedules Established RLDCs, SLDCs Current Scenario

13. 13 Market Structure Prior to Electricity Act, 2003 (Bundled)

14. 14 Market Structure after Electricity Act, 2003

15. 15 Road map for market development Forward Physical Contracts (Long-term)- Established; Moving from Regulated Cost-Plus PPAs to Tariff-bid based PPAs for new generating capacity Forward Physical Contracts (Short-term)- Established; but non-standard contracts Day ahead Spot Market thru’ PX? Real Time Market (Substituted by UI mechanism)

16. 16 International Experience Nord Pool PJM UK experience California PX South Africa/ ESKOM

17. 17 Appropriate PX design for India National power exchange Vs many power exchanges Mandatory Vs Voluntary participation Double side bidding Vs Supply side bidding Uniform pricing Vs Discriminatory pricing Day-ahead exchange Vs Same day exchange Time block for bidding (hourly/half-hourly etc) Congestion management Taking care of operational inflexibilities of generating stations

18. 18

19. 19 Expectations of a Portfolio Manager Freedom to sell and buy at short notice through a single window No cap at seller’s bids Reasonable cost of purchase Assured availability Assured delivery/take off Assured payments

20. 20 Open Access charges for PX schedules would be socialized. Transmission losses to be applied on PX participants as applicable. Part inter- regional capacities would be assigned for PX. RLDC time line and IEGC would be complied. PX schedules would be firm.

22. 22 Does Px need Licence Membership to Grid connected entities only Whether to allow membership to traders Px- to be a profit or non profit organisation Role of CERC Issues- General

23. 23 Issues- General Do we really need a Day-ahead PX, now or in the near future? What would be the right time? How to mandate a national PX by law? How to organize a national PX?

24. 24 Issues- Price Discovery and Bidding Pricing principles Bid caps, to have them or not Can bid caps be effective Sale price in constrained Market Can we curb market power/abuse How can Run of River, Thermal, Nuclear and Windmill Generators submit hourly day-ahead bids?

25. 25 Issues- Preventing Market Abuse Common market abuses Bidding above the marginal cost Withholding Capacity Avoiding a platform with lower price caps What would it feel like if most often the marginal bids for Market Clearing Price were of liquid fuel generators?

26. 26 Issues- Market Regulation Defining the Rules of the Game Enforcing the Rules and Regulations Market Monitoring Ensuring Anonymity of Bids

27. 27 Issues- Congestion Management To collect congestion revenue Or Not by charging the Buyers of congested zone at the cost of PX purchase instead of the price offered by the Buyers?
