CAISO kicked off a new Storage Design and Modeling Initiative intended to tackle an array of challenges related to the growing market participation of storage resources.

CAISO's Department of Market Monitoring reported that the ISO saw “one of the highest demand peaks” in recent years in 2024.

FERC approved fines on Sonoran West Solar Holdings for submitting misleading initial state of charge values that led to undue bid cost recovery payments.

First-quarter electricity prices in CAISO markets were down sharply from the same period in 2023, despite sharp spikes during the January cold snap in the Pacific Northwest, the ISO’s Department of Market Monitoring said.

CAISO is reconsidering its proposal to address unwarranted bid cost recovery payments for storage resources following internal analysis that suggested the proposed solution wouldn’t sufficiently address the problem.

Protecting the public interest while implementing the Extended Day-Ahead Market and expanding the Western footprint was central to the discussion in a West-Wide Governance Pathways Initiative workshop.

FERC accepted CAISO’s proposal to allow for storage resources to bid above the ISO’s $1,000/MWh soft offer cap in the real-time market to account for their intraday opportunity costs.
