Powerex intends to terminate a large portion of its rights on PacifiCorp’s transmission system in response to the utility’s plans to update its transmission tariff to align with CAISO’s EDAM.

New findings from a much-anticipated study have “not shifted” BPA's staff recommendation that the agency choose SPP’s Markets+ over CAISO’s — despite results showing greater economic benefits from EDAM.

FERC granted CAISO a waiver allowing PGE to join the ISO’s Extended Day-Ahead Market a few months beyond the timeline set out in the market’s standard participation agreement.

Pathways released its Step 2 draft proposal for dividing up functions between CAISO and the new “regional organization” that initiative backers are seeking to create to oversee the ISO’s Western real-time and day-ahead markets.

PacifiCorp is poised to realize up to $359 million a year in net benefits from participating in CAISO’s EDAM, nearly double a previous estimate, according to a newly updated study by The Brattle Group.

CAISO is recommending it implement a Western Power Trading Forum proposal that could help the EDAM track and account for GHG emissions in a way that considers the variety of carbon pricing programs across the West.

Stakeholder comments filed with the West-Wide Governance Pathways Initiative illustrate the complexity of building the new kind of Western regional organization envisioned by backers of the effort.

The Bonneville Power Administration will delay its Western day-ahead market choice beyond a scheduled Aug. 29 announcement date and likely will extend the decision-making process into 2025, according to multiple sources.
