FERC puts six hydro projects on Ohio’s Muskingum River up for review

The Federal Energy Regulatory Commission on May 24 issued a notice of scoping meetings and environmental site reviews for six license applications from units of Boston-based Free Flow Power for hydro projects in Ohio.

The applicants 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; and Clean River Power MR-7 LLC.

The proposed projects are located at existing locks and dams formerly owned and operated by the U.S. Army Corps of Engineers but now owned and operated by the state of Ohio on the Muskingum River in Washington, Morgan, and Muskingum counties.

The projects are:

  • The proposed Devola Lock and Dam Project would be located at the existing Devola Lock and Dam on the Muskingum River at RM 5.8. The applicant proposes to remove 187 feet of the existing dam to construct a 154-foot-long overflow weir. The project would also consist of new facilities including: a 80-foot by 160-foot powerhouse located on the bank of the river opposite the existing lock; two turbine-generator units providing a combined 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 to connect the project substation to the local utility distribution lines.
  • The Lowell Lock and Dam Project would be located at the existing Lowell dam at RM 13.6. The applicant proposes to remove 204 feet of the existing dam to construct a 143.5-foot-long overflow weir. The project would include: a 75-foot by 160-foot powerhouse located adjacent to the left bank of the dam; two turbine-generator units providing 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 to connect the project substation to the local utility distribution lines.
  • The proposed 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 river; two turbine-generator units providing 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 to connect the project substation to distribution lines.
  • The proposed Malta/McConnelsville Lock and Dam Project would be located at the existing Malta/McConnelsville dam at RM 49.4. The applicant proposes to remove 187.5 feet of the existing dam to construct a 100-foot-long overflow weir. The project would incude: a 80-foot by 160-foot powerhouse located adjacent to the right bank of the dam; two turbine-generator units with 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 distribution lines.
  • The proposed Rokeby Lock and Dam Project would be located at the existing Rokeby dam at RM 57.4. The project would include: a 75-foot by 160-foot powerhouse located on the bank of the river opposite the existing lock; 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 distribution lines.
  • The proposed Philo Lock and Dam Project would be located at the existing Philo dam at RM 68.6. The applicant proposes to remove 128 feet of the existing dam to construct a 40-foot-long flap gate. The project would include: a 75-foot by 160-foot powerhouse located on the bank of the river opposite the existing lock; two turbine-generator units with 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 distribution lines.

The applicants propose to operate all six 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 Beverly, Devola, Malta/McConnelsville, Lowell, Philo, and Rokeby projects would have average annual energy production values of 17,850 megawatt-hours (MWh), 20,760 MWh, 21,900 MWh, 31,000 MWh, 15,960 MWh, 17,180 MWh, respectively.
