CAISO’s Department of Market Monitoring urged the ISO to replace its interim congestion revenue allocation rules under its forthcoming Extended Day-Ahead Market “as soon as practicable.”

The size and configuration of day-ahead markets in the West will greatly impact electricity bills and grid reliability, says the Environmental Defense Fund.

CAISO is moving toward approval of an $8.5 million financing plan for the Regional Organization for Western Energy’s start-up costs.

One of the first items the yet-to-be-seated board of the Regional Organization for Western Energy could decide on is whether to administer a resource adequacy program, as backers seek to have a proposal in place later in 2026.

Participants in CAISO’s Extended Day-Ahead Market likely would remain subject to the market’s daily resource sufficiency evaluation even if they joined a new resource adequacy program that’s being crafted.

As Nevada regulators consider NV Energy's request to join CAISO's Extended Day-Ahead Market, the debate over the independence of EDAM's governance is intensifying.

For the first time in years, California’s grip on Western market design is genuinely at risk, writes Nick Myers of the Arizona Corporation Commission.

It’s an “all-hands-on-deck” moment for CAISO to open its extended day-ahead market in less than two months, CAISO’s CEO Elliot Mainzer said at a Western Energy Market Board of Governors meeting.

Conversations remained cordial despite the ongoing competition between CAISO and SPP in the west as the RTOs’ top executives took the stage at Yes Energy’s annual EMPOWER conference.

Arizona Public Service would save $110 million/year by joining CAISO's Extended Day-Ahead Market rather than SPP's Markets+, a new analysis found.
