The Federal Energy Regulatory Commission on Dec. 26 issued a successive preliminary permit to the city of Guttenberg, Iowa, to further study the feasibility of the 20-MW Guttenberg Water Power Project.
This project is to be located at the existing U.S. Army Corps of Engineers’ Lock and Dam 10 on the Mississippi River, near the township of Guttenberg in Clayton County, Iowa.
The proposed project would include: an existing 140-foot-wide by 280-foot-long auxiliary lock; a new 110-foot-wide by 250-foot-long concrete powerhouse containing four new 5-MW pit-type horizontal turbine units for a total capacity of 20 MW; an existing local step-up transformer; and a new 300-foot- long, 69-kV transmission line extending from the local transformer to the interconnection point with the local grid, which is owned and operated by the city of Guttenberg. The estimated annual generation of the project would be 63,400 megawatt-hours.
The applicant previously held a preliminary permit for this site. The commission grants successive permits if it concludes that the applicant has diligently pursued the requirements of its prior permits in good faith.
“City of Guttenberg has provided information to Commission staff demonstrating that it is currently making progress with the analysis of the project’s feasibility, and towards the development of its proposed project,” FERC noted. “During the first preliminary permit, City of Guttenberg: (1) filed with the Commission required six-month progress reports; (2) collected and analyzed three years of river stage and flow data; (3) contacted technology manufacturers and consulted with both state and U.S Army Corps of Engineers personnel; and, (4) reviewed comments filed by the Wisconsin [Department of Natural Resources] and discussed the Project with Iowa DNR officials. It is expected that during this permit term, agency consultation will continue and a development application will be prepared pursuant to sections 4.38 and 4.41 of the Commission’s regulations.”
