SPP says its Markets+ day-ahead offering in the Western Interconnection is on track to be completed by the end of the year.

CAISO, SPP and the Western Power Pool are all maneuvering to organize the Western electricity sector, and conditions finally seem ripe for change.

SPP’s MMU is “strongly” recommending that TCRs' funding shortfall be considered a high-priority item, according to its latest quarterly market reports.

Public Service Company of Colorado, Platte River Power Authority and Black Hills Colorado Electric said they plan to join SPP’s WEIS market in April 2023.

SPP’s Board of Directors approved the RTO’s third competitive transmission project, awarding a 345-kV line’s construction to NextEra Energy Transmission.

The Western Energy Imbalance Market is poised to make its largest expansion ever next spring with the inclusion of the Bonneville Power Administration.

The WEIM approved participation by utilities within an entity's balancing authority area — a move intended to convince Xcel Energy Colorado to join the market.
