New Colgate Powerhouse - 340 Megawatts

New Colgate Powerhouse is located on the main stem of the Yuba River downstream of the convergence of the North Yuba River, Middle Yuba River, and Oregon Creek.

Water is carried nearly five miles from New Bullards Bar Reservoir through a 26-foot-diameter tunnel, and then makes its way down a 15-foot-diameter penstock to drive two of the largest single-cast turbines ever built. These turbines produce 340 megawatts, which is enough electricity for 350,000 people.
