Free Flow Power units seek FERC approvals for Ohio hydro projects

The Federal Energy Regulatory Commission said in a May 8 notice that it has gotten seven applications for “run of river” hydroelectric projects with a total of 25 MW of capacity to be located at existing locks and dams on the Muskingum River in Washington, Morgan, and Muskingum counties, Ohio.

The locks and dams were formally owned and operated by the U.S. Army Corps of Engineers, but are now owned and operated by the Ohio Department of Natural Resources, Division of Parks and Recreation.

“The applicant proposes to operate all seven projects in a run-of-river mode, such that the water surface elevations within each project impoundment would be maintained at the crest of each respective dam spillway,” the commission said.

The affiliated companies pursuing these projects are: Clean River Power MR-1 LLC; Clean River Power MR-2 LLC; Clean River Power MR-3 LLC; Clean River Power MR-5 LLC; Clean River Power MR-6 LLC; Clean River Power MR-7 LLC; and Clean River Power MR-8 LLC. They are subsidiaries of Free Flow Power Corp.

These applications have been accepted for filing, but are not ready for environmental analysis at this time, FERC noted.

  • The proposed Zanesville Lock and Dam Project would be located at the existing Zanesville dam at river mile (RM) 77.4. The project would include two turbine-generator units providing a combined installed capacity of 2 MW; a 40-foot by 40-foot substation; and a 400-foot-long, three-phase, overhead 69-kV transmission line to connect the project substation to the local utility lines. Average annual generation would be about 12,295 MWh.
  • The proposed Philo Lock and Dam Project would be located at the existing Philo dam at RM 68.6. The project would include the following new facilities: two turbine-generator units providing a combined installed capacity of 3 MW; a 40-foot by 40-foot substation; and a 1,600-foot-long, three-phase, overhead 69-kV transmission line to connect the project substation to the local utility distribution lines. The average annual generation would be about 15,957 MWh.
  • The Rokeby Lock and Dam Project would be located at the existing Rokeby dam on the Muskingum River at RM 57.4. The project would include two turbine-generator units providing a combined installed capacity of 4 MW; a 40-foot by 40-foot substation; and a 490-foot-long, three-phase, overhead 69-kV transmission line to connect the project substation to the local utility lines. The average annual generation would be about 17,182 MWh.
  • The Malta/McConnelsville Lock and Dam Project would be located at the existing Malta/McConnelsville dam at RM 49.4. The project would include two turbine-generator units providing a combined installed capacity of 4 MW; a 40-foot by 40-foot substation; and a 1,500-foot-long, three-phase, overhead 69-kV transmission line to connect the project substation to the local utility lines. The average annual generation would be about 21,895 MWh.
  • The Beverly Lock and Dam Project would be located at the existing Beverly Lock and Dam at RM 24.6. The project would include: a 75-foot by 160-foot powerhouse located downstream of the dam on the left bank of the Muskingum River; two turbine-generator units with a combined installed capacity of 3 MW; a 40-foot by 40-foot substation; and  a 970-foot-long, three-phase, overhead 69-kV transmission line. The average annual generation would be about 17,853 MWh.
  • The Lowell Lock and Dam Project would be located at the existing Lowell dam at RM 13.6. The project would include: a 75-foot by 160-foot powerhouse located adjacent to the left bank of the dam; two turbine-generator units with a combined installed capacity of 5 MW; a 40-foot by 40-foot substation; and a 1,200-foot-long, three-phase, overhead 69-kV transmission line. The average annual generation would be about 30,996 MWh.
  • The Devola Lock and Dam Project would be located at the existing Devola Lock and Dam at RM 5.8. The project would include: a 80-foot by 160-foot powerhouse located on the bank of the Muskingum River opposite the existing lock; two turbine-generator units with total installed capacity of 4 MW; a 40- foot by 40-foot substation; and a 3,600-foot-long, three-phase, overhead 69-kV transmission line. The average annual generation would be about 20,760 MWh.
