INITIATIVE:
Energy storage enhancements

Joint Authority
Started: Feb 01, 2021

Leads
Daniel Johnson

This initiative aims to enhance the optimization, dispatch, and settlement of energy storage and other similarly-situated resources, through developing bid enhancements to help resources accurately represent their marginal costs in the real-time market; ensure the ISO has sufficient state-of-charge to cover critical hours; and explore modifications to the ISO’s exceptional dispatch and bid cost recovery mechanisms.
