• 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

Page 5: CERC

• 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 .

• 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.

• 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

• 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

Page 12: CERC

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

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)

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

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

• 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.

Issues- General

Page 23: CERC

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?

Page 24: CERC

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?

Page 25: CERC

25

Issues- Preventing Market Abuse

Common market abuses1. Bidding above the marginal cost2. Withholding Capacity3. 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?

Page 26: CERC

26

Issues- Market Regulation

Defining the Rules of the Game Enforcing the Rules and Regulations Market Monitoring Ensuring Anonymity of Bids

Page 27: CERC

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?
