INITIATIVE:
Resource adequacy enhancements

Started: Oct 30, 2018

Leads
Bridget Sparks

The rapid transformation of resources to a cleaner, variable and energy limited fleet is driving the need to re-examine the ISO’s Resource Adequacy program. In this initiative the California ISO, in collaboration with the California Public Utilities Commission and stakeholders, will explore reforms needed to the ISO’s resource adequacy rules, requirements, and processes to ensure the future reliability and operability of the grid.

Phase 2

Phase 2 of this initiative explores methodologies for calculating unforced capacity (UCAP) values for system, local, and flexible resource adequacy (RA) requirements, setting minimum system RA requirements, system RA energy sufficiency testing, resource adequacy import provisions, must offer obligations and bid insertion rules, additional planned outage process enhancements, and modifications to the ISO’s backstop capacity procurement provisions.

Phase 1

Phase 1 of this initiative explores topics including operationalizing storage, backstop capacity procurement authority for local area energy sufficiency, and initial enhancements to the ISO’s current planned outage process.
