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.

The consequences of the Bonneville Power Administration’s decision to join SPP’s Markets+ could hit the Northwest sooner rather than later even though the agency has yet to formally join the market, a group of nonprofits suing it over the choice told the 9th U.S. Circuit Court of Appeals.

CAISO released a set of guiding principles for upcoming discussions about seams between the ISO, SPP and other entities as the Extended Day-Ahead Market nears its opening in May.
