PacifiCorp is preparing to bring online enough long-term clean energy resources to help the utility meet Washington's strict greenhouse gas targets by 2030.

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.

The push to develop a resource adequacy program serving non-CAISO members of the ISO’s Extended Day-Ahead Market appears to be gathering momentum, with backers saying they aim to produce a draft design for the program in April.

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.

Portland General Electric has agreed to buy most of PacifiCorp’s Washington utility operations for $1.9 billion.

CAISO’s Western Energy Imbalance Market surpassed $8 billion in cumulative economic benefits since its 2014 launch after providing participants with $415.65 million in gross benefits in the fourth quarter of 2025, according to an ISO report.

CAISO leaders staged a virtual “town hall” to stress the importance of a smooth rollout to the ISO’s Extended Day-Ahead Market in May and promise to address market seams issues.

The Bonneville Power Administration provided updates on the agency’s $5 billion in transmission projects as some stakeholders asked about sunsetting of tax credits and coordination efforts with other developers in the West.

The Extended Day-Ahead Market took center stage at CAISO in 2025 as the ISO tabled other long-term initiatives to ensure the market’s timely launch in May 2026, with PacifiCorp as its first participant.
