Grand Coulee Dam Overhaul Completed

The Bureau of Reclamation and the Bonneville Power Administration are celebrating the completion of a major overhaul at Grand Coulee Dam that was over a decade in the making.

According to the Bureau of Reclamation, three of the dam's 33 hydroelectric units were completely disassembled and restored to like-new condition. The restored units now experience less friction, meaning they will operate with less wear and tear and will be more reliable and efficient.

Planning for the project inside the Nathanial "Nat" Washington Power Plant began all the way back in 2008. The project's final returned to service September 30th.

The Grand Coulee Dam can generate more than 6,800 megawatts and annually supplies more than 20 billion kilowatt hours of electricity to the region. It came on line in 1941.
