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.

FERC has rescinded the West-wide wholesale electricity price cap mechanism it implemented in response to widespread price manipulation during the Western energy crisis of 2000/01, saying development of new markets and expanded authority has led to improved monitoring capabilities.

The Regional Organization of Western Energy selected Western Freedom Executive Director Kathleen Staks as its interim president, while regulatory attorney Lisa Tormoen Hickey will assume the role of interim secretary.

Elliot Mainzer said working at BPA taught him two critical lessons that he's applied at CAISO: the importance of "robust stakeholder engagement" and "collaborative working relationships."

Some parties are urging Nevada regulators to wait until initial results are in for CAISO's Extended Day-Ahead Market before deciding whether to allow NV Energy to join.
