The Federal Energy Regulatory Commission sent an Aug. 16 letter to Cedar Creek Hydro LLC and Symbiotics LLC asking for a tardy six-month progress report on a 660-MW pumped storage hydro project in Texas.
FERC in September 2012 had granted the companies a successive preliminary permit for this project, which requires the filing of six-month project updates with the commission during the 36-month permit term. “This letter constitutes notice under section 5 of the Federal Power Act of the probable cancellation of the preliminary permit no less than 30 days from the date of this letter,” said the Aug. 16 letter.
On April 2, 2012, Cedar Creek Hydro had filed an application for a preliminary permit to study the feasibility of a hydropower project located in Briscoe, Armstrong and Randall counties, Texas.
The proposed Cedar Creek Pumped Storage project would consist of: a 60-foot-high, 12,700-foot-long earth embankment upper dam; an upper reservoir with a surface area of 283 acres and a storage capacity of 7,660 acre-feet; a 28-foot-diameter, 3,720-foot-long steel penstock; a powerhouse/pumping station containing three pump/generating units with a total capacity of 660 MW; a 140-foot-high, 1,600-foot-long earth embankment lower dam; a lower reservoir with a surface area of 151 acres and a storage capacity of 8,550 acre-feet; and a 26-mile-long, 240-kV transmission line.
The project would have an estimated average annual generation of 1,816,000 megawatt-hours.
