CERC's staff paper on capacity markets proposed three potential uses cases for capacity markets:
Use Case 1: Meeting Resource Adequacy (RA) Obligations
Use Case 2: Meeting Reserve Requirements
Use Case 3: Procuring Short-Term Power from Existing Capacity
Prayas’s detailed submission in this matter focusses on the following:
- Supports Use Case 2 (Meeting Reserve Requirements) but recommends that clear specification of NLDC net cone determination methodology for cap fixation, frameworks for capping and screening of energy/ compensation charge and methodology for determination of commitment charge. These aspects can be detailed by CERC in consultation with NLDC after approved after public consultation.
- Recommends replacement of fragmented contracts such as LDC, ADSS and DEEP with standardised block-bid contracts on power exchanges across six pre-specified time slots. This can help increase liquidity in short-term markets more than proposed capacity design in Use Case 3.
- Advises a cautious approach while exploring capacity markets for long-term resource adequacy (Use Case 1). This is due to risks of inflated capacity bids/ net CONE, distorted market price signals, constraints on future market evolution, transmission cost uncertainties, and DISCOM cash flow challenges. As an immediate alternative, strengthening of enforcement of Rule 9 of the LPS Rules is recommended, with targeted amendments proposed to make compliance workable.
