FERC okays original license for 5-MW hydro project in Kentucky

The Federal Energy Regulatory Commission on May 5 approved an April 2015 application from FFP Project 92 LLC for an original license to construct and operate the proposed Kentucky River Lock and Dam No. 11 Hydroelectric Project (L&D 11 Project).

The 5-MW project will be located at the Kentucky River Authority’s Lock and Dam No. 11 on the Kentucky River, near the Town of Waco in Madison and Estill counties, Kentucky. The project will not occupy federal land.

The L&D 11 Project dam is located at river mile (RM) 201. In 2015, commission staff issued licenses for projects at two upstream lock and dam structures: Lock 12 Partners’ Ravenna Hydroelectric Project at Lock and Dam No. 12 (RM 220.9); and Lock 14 Hydro Partners LLC’s Heidelberg Hydroelectric Project at Lock and Dam No. 14 (RM 249).

Lock and Dam No. 11 consists of a 208-foot-long, 35-foot-high fixed concrete gravity dam that acts as an uncontrolled spillway at a crest elevation of 583.05 feet, an abandoned 148-foot-long, 52-foot-wide navigation lock structure located on the south river bank, and a 579-acre reservoir (Pool No. 11).

The project will include the following new facilities: a 275-foot-long, 75-foot-wide reinforced concrete intake located in the abandoned lock and partly within an existing esplanade; a 260-foot-long, 47-foot-high intake channel guide wall to be installed along the esplanade to convey flows to be used for generation into a 30-foot-long, 47- foot-high, 64.5-foot-wide intake and headgate structure to be built within the existing lock structure and extending beyond the south lock wall into the riverbank; and trash racks with 3-inch clear bar spacing to be installed on the project intake.

The powerhouse will contain two 2.5-MW horizontal pit Kaplan turbine generator units, for a total installed capacity of 5 MW. Flows exiting the powerhouse will be returned to the Kentucky River through a 190-foot-long, 78-foot-wide reinforced concrete tailrace channel with a 295-foot-long, 35-foot-high retaining wall.

The project’s transmission facilities will include a new 40-foot-long by 40-foot-wide 69-kV substation with a new 212-foot-long, 4.16-kV underground transmission cable from the powerhouse to the substation, and an approximately 4.5- mile-long, 69-kV overhead transmission line extending from the substation to an existing substation located near Waco, Kentucky.

As noted above, the commission issued original licenses for the Heidelberg and Ravenna projects with 40-year terms, expiring Dec. 31, 2055. To coordinate the license term of the L&D 11 Project with the Heidelberg and Ravenna license orders, this license is for a 39-year, 8-month license term, to coincide with the expiration of the Heidelberg and Ravenna projects.
