The six generating units that comprise the Third Powerplant have been in service since the mid 1970s and are starting to have problems stemming from age-related wear on the principle components which have resulted in increased power outages and reduced reliability. The proposed overhaul will ensure continued operation and allow Reclamation to provide a reliable source of hydroelectric power.

The four proposed alternatives in the Draft EA include: No Action; Third Powerplant Overhaul, and construction of a separate material storage building; Third Powerplant Overhaul with expansion of Third Powerplant for storage, and Third Powerplant Overhaul with expansion of the powerplant and construction of a separate material storage building.

A Draft EA is available for review, with the comment period ending on October 20. The document is available online at http://www.usbr.gov/pn/programs/ea/wash/tpp/index.html and also at the Grand Coulee Dam Visitor Center located just downstream from Grand Coulee Dam.
