FERC okays original license for 3-MW hydro project in Ohio

The Federal Energy Regulatory Commission on Dec. 30 approved a 2012 application from Clean River Power MR-3 LLC for an original license to construct, operate, and maintain the 3-MW Beverly Lock and Dam Water Power Project, to be located at the Ohio Department of Natural Resources’ Beverly Dam on the Muskingum River in Washington and Morgan counties, Ohio.

The Beverly Lock and Dam, also known as the Muskingum River Lock and Dam No. 4, is a 535-foot-long, 17-foot-high timber crib and concrete structure with a full-length, uncontrolled spillway at a crest elevation of 616.36 feet North American Vertical Datum of 1988 (NAVD 88). A 160-foot-long, 35-foot-wide navigation lock with hand-operated miter gates at both ends is located on the east river bank.

The project will include these new facilities:

  • A 135-foot-long by 160-foot-wide by 20-foot-deep intake channel to be excavated upstream of Beverly Dam to convey flows to be used for generation into a 37-foot-long by 88-foot-wide by 52-foot-high intake structure. Trashracks with 2-inch clear bar spacing will be installed on the project’s intake.
  • Flows for generation will pass through the intake to a new 160-foot-long by 75-foot-wide by 66-foot-high concrete powerhouse that will be integral with the dam and located on the west river bank. The powerhouse will contain two 1.5-MW horizontal  Kaplan turbine/generator units. Flows exiting the powerhouse will be returned to the Muskingum River through a 90-foot-long by 150-foot-wide by 19-foot-deep tailrace  channel.
  • The project’s transmission facilities will include a new substation located adjacent to the powerhouse, a 206-foot-long, 4.16-kV cable to connect the powerhouse to the substation, and a 970-foot-long, 69-kV overhead transmission line to connect the  substation to a local utility distribution line.

The project will operate in a run-of-river mode, such that outflow from the project approximates inflow. The project will generate an average of 17,853 megawatt-hours (MWh) annually.

FERC’s Office of Energy Projects in August had issued a draft environmental assessment covering six license applications for small hydroelectric projects in Ohio, including this one. The proposed projects, being pursued by project affiliates of Boston-based Free Flow Power, would be located on the Muskingum River.
