Hydropower Generation in the West Set to Recover Despite Snow Drought
The U.S. Energy Information Administration (EIA) forecasts a 5% increase in U.S. hydropower generation for 2026, despite ongoing snow drought conditions in several western states. This projection, detailed in the April Short-Term Energy Outlook (STEO), anticipates a total generation of 259 billion kilowatt-hours (BkWh), which is 1.8% below the 10-year average. The Northwest and Rockies regions are expected to see a 17% increase in hydropower output compared to 2025, reaching 125 BkWh. This recovery follows a period of unusually high generation in late 2025 and early 2026, driven by atmospheric rivers that caused significant flooding. In California, hydropower generation is projected to be 28.5 BkWh, 6% less than the previous year but 15% above the 10-year average. Reservoir levels in California are above historical averages, although snowpack levels remain below normal due to warmer winter temperatures.
