Last year, U.S. hydropower electricity generation fell to its lowest since 2001. This year, we expect hydropower to increase 6% and account for 250 billion kilowatthours of electricity generation in the power sector, based on forecasts in our Short-Term Energy Outlook (STEO). We expect hydropower to increase in nearly every part of the country, with notable increases in the Southeast and in the Northwest and Rockies. We expect other regions with significant hydropower generation to either increase slightly, such as in New York, or remain about the same, such as California.
