Lock 13 Hydro seeks permit for 2.8-MW project in Kentucky

Lock 13 Hydro Partners applied Sept. 1 at the Federal Energy Regulatory for a Preliminary Permit, good for three years of project feasibility work, for the Evelyn Hydroelectric Station, to be located on the Kentucky River in Lee County, Kentucky.

Lock 13 Hydro Partners proposes to evaluate the possibility of adding hydro generation to the existing lock and dam owned by the Commonwealth of Kentucky and operated by the Kentucky River Authority. Lock 13 Hydro Partners is submitting the application in order to secure priority in the licensing process while it studies the project’s feasibility and develops a license application.

The proposed project would place five 1500 mm Flygt submersible turbine-generators into the existing abandoned lock chamber at Lock 13 on the Kentucky River. The existing dam and lock chamber were built between 1909 and 1915 and are made of concrete. The lock and dam were put into operation in 1914. While built for navigation, the dam is presently used for recreation and water supply. The dam is 248 feet in length, with a 52 foot wide lock chamber. The dam has a structural height of 35 feet.

The lock chamber is abandoned and a concrete bulkhead has been placed in the lock chamber just below the upper miter gates to prevent failure and loss of pool. The dam is located at mile 239.9 on the Kentucky River. There are no existing penstocks, powerhouses, or tailraces at the site.

The proposed project would not change the dam height or have any affect on river levels, as it would be operated in a run-of-river mode. A distribution line owned by Jackson Energy Cooperative runs within 1,000 feet of the project site. This line will need to be upgraded. The project would interconnect directly into this distribution line; thus no new or additional transmission facilities will be required.

The company would install five new 1500 Flygt turbines with integrated submersible 560 KW induction generators. The combined capacity of the five turbine/generators would be 2,800 kW (2.8 MW). The estimated annual output would be on average 11,600 Megawatt-hours annually.

The project would contain no penstocks or traditional powerhouse. The submersible turbine/generators would be located in the existing lock structure. Project controls and switchgear would be located in a new building to be located on the shore, above the 500-year flood level.
