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.

PNM exhausted every alternative before postponing the retirement of the coal-fired San Juan plant until the end of this summer, a utility executive said.
