Statutory Provisions • 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. 4
Current Scenario • 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 is essential for resource optimisation and meeting short term peak demand for disposing off surpluses which are inevitable as a utility has no direct control over consumer load. Trading essentially between surplus & deficit distribution utilities. 5
ALL INDIA POWER SUPPLY SCENARIO (April, 2005 - March, 2006) 6
Current Scenario • 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. 7
Short-term Trading Volume Traded Volume in MU 16000 11029 11847 14188 FY 04 FY 05 FY 06 12000 8000 4178 1617 0 FY 02 FY 03 8 *For FY-07: 15 BU Estimated
Current Scenario • 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 9
Price trend of traded electricity 10
Current Scenario • • • Need to curb sellers’ domination • • • Need to increase the supplies • For optimum resource management, need to simultaneously clear energy contracts & transmission paths. Need to put on end to profiteering Need to organize short term trading on a transparent, equitable and efficient platform Need to bring surplus captive generation into the grid. Need to encourage peaking power plants and merchant generation. 11
Current Scenario §Adequate Inter-state transmission system, but needs strengthening §Established scheduling, dispatch energy accounting procedures § and UI accounting system for real time deviations from schedules §Established RLDCs, SLDCs 12

Expectations of a Portfolio Manager n Freedom to sell and buy at short notice through a single window n No cap at seller’s bids n Reasonable cost of purchase n Assured availability n Assured delivery/take off n Assured payments 19
Transmission and System Operation • 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. 20
