FERC seeks enviro plan input on two hydropower projects in Kentucky

The Federal Energy Regulatory Commission issued an environmental assessment on Feb. 24 that covers applications for original licenses for the Heidelberg Hydroelectric Project and Ravenna Hydroelectric Project.

The proposed projects would both be located on the Kentucky River in Kentucky. The Heidelberg Project would be located at the Kentucky River Authority’s Lock and Dam No. 14 near the Town of Heidelberg in Lee County. The Ravenna Project would be located at the Kentucky River Authority’s Lock and Dam No. 12 near the Town of Ravenna in Estill County. Any comments on the EA should be filed within 30 days from the date of this Feb. 24 notice.

In May 2012, Lock 14 Hydro Partners LLC and Lock 12 Hydro Partners LLC filed applications with FERC to construct, operate, and maintain the proposed 2.64-MW Heidelberg project and the 2.64-MW Ravenna project, respectively. The proposed projects would use KRA’s existing lock and dam features and would involve constructing a powerhouse within abandoned navigation locks as well as new transmission lines.

  • The Heidelberg Project would consist: of an existing concrete gravity dam; an abandoned navigation lock; a stone dike that tapers down from a 20-foot maximum height to ground level; an existing 182-acre reservoir with a gross storage capacity of about 1,820 acre-feet; a new trashrack to be installed on the upstream side of the powerhouse; a new concrete powerhouse containing four 660-kW Kaplan turbine/generator units with a total capacity of 2.64 MW; and a new 1,000-foot-long, 12.47-kV overhead transmission line that would connect to Jackson Energy Cooperative’s distribution line.
  • The Ravenna Project would consist of: an existing concrete gravity dam, an abandoned navigation lock; an earthen dike that tapers down from a 13-foot maximum height to ground level; an existing 345-acre reservoir with a gross storage capacity of about 3,450 acre-feet; a new trashrack to be installed on the upstream side of the powerhouse; a new concrete powerhouse containing four 660-kW Kaplan turbine/generator units with a total capacity of 2.64 MW; and a new 1,500-foot-long, 12.47-kV overhead transmission line that would connect to Jackson Energy Cooperative’s distribution line.

Both projects would operate run-of-river, utilizing flows between 150 and 2,100 cubic feet per second (cfs) for power generation.  The Heidelberg and Ravenna Projects would have an average annual generation of 10,484 megawatt-hours (MWh) and 10,673 MWh, respectively.
