The push to develop a resource adequacy program serving non-CAISO members of the ISO’s Extended Day-Ahead Market appears to be gathering momentum, with backers saying they aim to produce a draft design for the program in April.

The West-Wide Governance Pathways Initiative will run its stakeholder processes separately from CAISO’s until the effort's regional organization is formally launched in 2028, even in areas of overlapping interest.

The dispute over how CAISO’s Extended Day-Ahead Market will allocate congestion revenues to market participants continues, even as the ISO moves to address stakeholder concerns.

Establishing a fast-start pricing mechanism in CAISO and the WEIM is complex and brings few benefits compared to other potential market enhancements, the ISO's Department of Market Monitoring said.
