The California Independent System Operator serves about 80% of California's electricity demand, including the service areas of the state's three investor-owned utilities. It also operates the Western Energy Imbalance Market, an interstate real-time market covering territory that accounts for 80% of the load in the Western Interconnection.
Western state utility commissioners should encourage “standardization and harmonization” to effectively integrate inverter-based resources throughout the region, according to a guide developed by WIRAB and Elevate Energy Consulting.
A new CAISO paper lays out a series of challenges around how to improve participation of demand response and distributed energy resources in the ISO's day-ahead and real-time markets.
The West-Wide Governance Pathways Initiative could lead the charge on developing an alternative to the Western Resource Adequacy Program that would integrate with CAISO’s Extended Day-Ahead Market, according to co-Chair Pam Sporborg.
A new report examines CAISO, MISO, PJM and SPP efforts to accelerate interconnection and concludes that while some may succeed in speeding generation additions, some sacrifice fairness, transparency and open-access principles.
FERC granted CAISO's request to remove the sunset date on the Western Energy Imbalance Market Assistance Energy Transfer feature, which has been used by more than 10 of the market’s balancing area authorities in recent years.
A new FERC report adds to the growing body of work showing the complexity of confronting the seams issues likely to arise between the West’s two day-ahead markets when compared with challenges at the borders between RTOs and ISOs in the Eastern U.S.
FERC largely approved compliance filings by three California investor-owned utilities related to interconnection queue requirements.
The CEC approved a request to increase the output of a Burbank gas-fired power plant to address grid reliability issues, prompting some organizations and locals to protest out of concerns about the facility's emissions and costs.
The buildout of new resources in the Western Interconnection over the next 20 years is “remarkably similar” across a variety of scenarios tested by NWPCC’s market availability study.
PacifiCorp is hiring additional employees to prepare for CAISO’s Extended Day-Ahead Market next year, with staff expecting the launch will bring a few “scratches and bruises.”
