The Federal Energy Regulatory Commission on March 17 granted a preliminary permit to OHP Energy LLC that allows the company three years of exclusivity to look at the feasibility of a 10-MW hydro project in Oregon.
In November 2014, OHP Energy filed an application for a preliminary permit for the proposed Applegate River Dam Hydroelectric Project, to be located on the Applegate River near the city of Medford in Jackson County, Oregon.
The proposed project would utilize head from the existing Applegate dam, reservoir, and a low level intake pipe owned and operated by the Corps, and consist of these new facilities: a multi-level withdrawal structure to withdraw water from the reservoir at centerline elevations of 1,933, 1,955 and 1,967 feet mean sea level; two 750-foot-long steel penstocks with diameters of 66-inches and 84-inches coupled with turbine shut-off valves at the intersection with the powerhouse and a bypass to the tailrace; a 55- by 55-foot powerhouse containing two vertical 5-MW Francis turbine/generating units with a total rated capacity of 10 MW; two 20-foot-long integral steel draft tubes located within the powerhouse; a 40-foot-long, 40-foot-wide open channel concrete tailrace; a 15-mile-long, 35-kV underground transmission line; and a substation. The estimated annual generation of the Applegate Project would be 28 gigawatt-hours.
Said the March 17 approval: “A preliminary permit is issued for the Applegate River Dam Hydroelectric Project No. 14647 to OHP Energy, LLC, for a period effective the first day of the month in which this permit is issued, and ending either 36 months from the effective date or on the date that a development application submitted by the permittee has been accepted for filing, whichever occurs first.”
