RegionWestMay 2026 data

Washington has among the cheapest electricity in the nation because roughly two-thirds of its generation is hydroelectric, which has essentially no fuel cost. Retail service is regulated. The climate west of the Cascades is genuinely mild, so cooling load is small by national standards, while cheap rates and electric heating make winter the dominant season.
