FERC gives Lock+ an extra two years for Mississippi River hydro project

The Federal Energy Regulatory Commission on Sept. 8 issued a successive preliminary permit, allowing Lock+ Hydro Friends Fund XLVIII an additional two years to study the feasibility of the proposed Mississippi River Lock and Dam 14 Hydropower Project, to be located at the U.S. Army Corps of Engineers’ Mississippi River Lock and Dam No. 14 near the City of Hampton in Rock Island County, Illinois.

The proposed project would be located completely within lands owned by the United States and consist of: three 105-foot-wide, 40-foot-high Large Frame Modules (LFM) each containing seven 860-kW turbines for a total installed capacity of 18,060 kW; a debris screen and fish screen placed upstream of the LFM; a 50-foot-long tailrace; a switchyard adjacent to the LFM installation and containing a new transformer and control room; and a 3.5-mile-long, 69 kV transmission line conveying the generated power to the local grid using an existing substation.

The LFM would be installed upstream of the dam in a single row across the Mississippi River on the side of the river farthest away from the navigational lock. The LFM would be anchored to new pilings or a concrete gravity structure in the river bed. The project is estimated to generate 102,000 megawatt hours annually.

The applicant has previously held a preliminary permit for this project. “The Commission will grant successive permits if it concludes that the applicant has diligently pursued the requirements of its prior permits in good faith,” FERC said in the Sept. 8 order. “Lock Hydro Friends filed a notice of intent to file a license application and a pre-application document under the Traditional Licensing Process, demonstrating that it is currently making progress with the analysis of the project’s feasibility, and towards the development of its proposed project. It is expected that during this permit term, agency consultation will be conducted and a development application will be prepared pursuant to sections 4.38 and 4.51 of the Commission’s regulations.”
