As part of the Market Enhancements for Summer 2021 Readiness initiative conducted earlier in the year, the ISO committed to undertaking an initiative to develop a long-term, holistic, framework for establishing scheduling priorities in the ISO market.  This initiative will evaluate the development of this holistic, long-term, framework while also evaluating near-term enhancements to the current scheduling priority framework that can be implemented by next summer.
