Four Arizona entities have joined seven Pacific Northwest entities to support the next phase of SPP’s Markets+ development.

Seven Western entities have now expressed support for participating in the next phase of SPP's market development in the Western Interconnection.

The Bonneville Power Administration has said it will become the first western utility to formally commit to funding development of SPP’s Markets+ in the West.

The Northwest stands out as an exception to the increasingly dire water situation gripping the wider West, boding well for its summer hydropower potential.

The Bonneville Power Administration experienced two major “price excursion” events in the Western EIM within two weeks of joining the market.

Climate change will have a mixed impact on hydropower in the Pacific Northwest, with wetter winters and springs and drier summers, BPA says.

SPP’s plan to develop a market to compete with CAISO's Western EIM got a boost from utilities and energy customers in the Pacific Northwest.

The Western EIM took on BPA and Tucson Electric Power as new participants, marking the market’s largest single expansion since its founding.

CAISO's Western Energy Imbalance Market surpassed $2 billion in total member benefits only 20 months after hitting the $1 billion mark in 2020.

The Bonneville Power Administration is on target to enter the Western EIM in early May after executives made a final determination on its market readiness.
