Western Energy Imbalance Market (WEIM)
The group working to establish a single Western RTO heard summaries of five potential options for a new governing body that could be independent of CAISO.
CAISO's Department of Market Monitoring explained that self-scheduled exports to support stressful conditions led to the declaration of emergency alerts in July.
CAISO’s curtailment of solar and wind power is on the rise, and about three-quarters of curtailments so far this year have been from transmission congestion.
CAISO is looking at scrapping a catalog of about 60 proposed policies, which include many stakeholder suggestions, saying the document has become “unwieldy” and it might be better to start over from scratch.
Electricity sector stakeholders expressed divisions over BPA's plan to pursue an aggressive timeline for deciding whether to join CAISO’s EDAM or SPP’s Markets+.
Idaho Power asked FERC to overturn a $700,000 fine for what it called a minor metering mistake that had no real impact on the Western Energy Imbalance Market.
CAISO asked FERC to approve the rules for its EDAM and revisions to its existing day-ahead market, intended to more accurately forecast load.
While some stakeholders are ‘charmed’ by SPP’s market initiative effort, others urge need for deeper tie to CAISO.
The Western Energy Imbalance Market topped $4 billion in cumulative benefits in the second quarter of 2023, just six months after it topped the $3 billion mark.
Utility regulators from Oregon and California discussed their proposal for a new independent RTO covering the entire West for the first time publicly.
