This paper proposes a novel framework to price energy storage in economic dispatch with a social welfare maximization objective. This framework can be utilized by power system operators to generate default bids for storage or to benchmark market power in bids submitted. Large Storage: Capacity Withholding (Extreme High Bid: $500-1000/MWh!) Default Bid? J.

Simulation results show that the proposed market design reduces electricity paymen CAISO) has exceeded 8. 6 GW in April 2024 and is. This contains code and data used for the paper: Qi N, Xu B.
