Modernization of Left and Right Powerhouses at Grand Coulee Dam

Reclamation has completed a final Environmental Assessment (EA)/Finding of No Significant Impact (FONSI) for the Grand Coulee Dam G1 – G18 Generating Units Modernization and Overhaul project.

Modernizing all 18 generating units in the Left and Right Powerhouses is anticipated to take approximately 10 years to complete. Restoring the generators, which have been in use for over 70 years, will ensure reliable future operations. The project addresses the need for restoration by working on two generating units simultaneously.
