As extreme weather events become more frequent and severe, the Pacific Northwest is facing heightened risk of power outages from downed or de-energized lines and damaged equipment. At the same time, recent studies project that the region could face a supply shortfall before 2030, indicating that there may not be enough generation to meet demand under all conditions. Together, extreme weather, growing demand, and a changing resource mix are placing greater stress on the system, which has prompted a robust discussion among policymakers about how best to ensure reliability while maintaining affordability.
