​Flexible resource adequacy criteria and must offer obligations

This initiative will explore further enhancements to flexible capacity requirements to help address generation oversupply and ramps less than three hours. This effort also seeks new rules to allow intertie resources and storage resources’ not operating under non-generator resource provisions to provide flexible capacity. Through this effort we will also assess the impact of merchant variable energy resources on flexible capacity requirements.


​Initiative status

Phase 2 of this initiative is substantively aligned with the ISO’s Day-Ahead Market Enhancement (DAME) initiative, by ensuring that forward procurement of flexible resource attributes support the ISO’s operational needs. The ISO has moved the planned implementation of 15-minute scheduling granularity from Fall 2019 to Fall 2020 and the day-ahead flexible ramping product to Fall 2021. The ISO will reassess the Phase 2 timeline in 2019.

Outcome
On November 6, 2014 the ISO began allowing load serving entities and suppliers to submit flexible capacity for annual and monthly Resource Adequacy based on FERC’s conditional approval of the ISO’s proposed tariff amendment. FERC subsequently approved further amendments that the ISO implemented on December 22, 2014 to enable procurement of backstop flexible capacity in the event of a cumulative deficiency.
