If the Northwest has a long cold snap, it may not have enough electricity, a consultant hired by utilities said. Up to now, the region has had enough power to meet extraordinary demand. But the surplus is expected to turn into a deficit in 2026, E3 senior partner Arne Olson told the Washington Senate Environment, Energy and Technology Committee on Dec. 5. Power plants that provide “firm” electricity, such as coal plants, are being shut down. Almost all new power plants are intermittent wind and solar installations. Windmills and solar panels make only a small contribution to grid reliability in cold snaps, according to Olson. Batteries typically supply power for only four hours, he said.“If you have an event that lasts three or four days, the four hours is really not that helpful,” Olson said.
