Black Canyon Dam Third Hydroelectric Generating Unit Project

Black Canyon DamThe Bureau of Reclamation is proceeding with a design for a new third hydroelectric generating unit at Black Canyon Diversion Dam located on the Payette River about 5 miles northeast of Emmett, Idaho. 

The proposed 12.5 MW hydroelectric unit will expand the capacity of the two existing 5 MW units with a one that  can generate 105 million kilowatt-hours (kWh). The power produced will serve 10 irrigation districts in southern Idaho and eastern Oregon, as well as the Shoshone-Bannock Tribes.

The additional generating unit will take advantage of water that typically would go over the dam and will turn it into pollution-free hydroelectric power. It will also provide operational flexibility when one of the existing units is shut down for maintenance.

The project is projected to cost about $53 million and to be funded by the Bonneville Power Administration (BPA). BPA markets the hydroelectric power generated at Reclamation facilities located in the Pacific Northwest.
