FERC grants permit for 2.3-MW Hydrodynamics project in Montana

The Federal Energy Regulatory Commission on Sept. 16 approved a preliminary permit that allows Hydrodynamics Inc. to spend up to three exclusive years looking at the feasibility of a 2.3-MW hydro project in Montana.

On Feb. 1, Hydrodynamics had filed an application for a preliminary permit on the Ruby River Reservoir Water Power Project, to be located on the Ruby River, near Alder in Madison County, Mont. The proposed project would use the existing Ruby River Dam and new outlet conduit, owned by the state of Montana.

The proposed project would consist of the following new facilities: an 84-inch-diameter, 180-foot-long concrete outlet tunnel lined with steel; an 84-inch-diameter, 20-foot-long penstock extending from the tunnel to the powerhouse; a powerhouse containing two generating units with a combined installed capacity of 2.3 MW; a tailrace discharging flows into the Ruby River at the base of the dam; a substation; and a 2-mile-long, 15-kV transmission line.

The proposed project would have an average annual generation of 10 gigawatt-hours.
