Northwest Energy Security Act

The Northwest Energy Security Act (S 966) requires federal agencies managing the Columbia River dams (FCRPS) to operate them strictly according to the 2020 Supplemental Opinion, which guides river operations. It prohibits any changes restricting hydroelectric power generation or Snake River navigation at FCRPS dams without explicit new federal law passed after this bill’s enactment. The bill allows limited operational adjustments only for public safety or grid reliability, with amendments requiring unanimous agreement among the three Secretaries (Interior, Energy, and Army). This directly affects how federal agencies manage dam operations in Washington, Oregon, and Idaho, preventing unilateral changes to power generation or river access. The law clarifies that routine maintenance and capital improvements for authorized dam purposes remain permitted.
