The Federal Energy Regulatory Commission issued a notice that the Western Minnesota Municipal Power Agency is giving up its preliminary permit on the proposed Mississippi Lock and Dam, Iowa-Hydroelectric Water Power Project.
The permit was originally issued in July 2011, extended by two years in May 2014, and would have expired on June 30, 2016. The project would have been located at the existing U.S. Army Corps of Engineers’ Mississippi River Lock and Dam No. 15 in Rock Island and Scott counties near Davenport, Iowa.
The preliminary permit will remain in effect until the close of business on June 24. But, if the commission is closed on this day, then the permit remains in effect until the close of business on the next day in which the commission is open. New applications for this site may not be submitted until after the permit surrender is effective.
The Western Minnesota Municipal Power Agency had proposed the development of: micro-turbine/generator arrays (11 units each) installed in nine of the existing roller gate bays (for a total of 99 units), witch each unit having a capacity of 500 kW, for a total installed capacity of 49.5 MW; and a new 9,700 foot-long, 69-kV transmission line that would connect into the local transmission system. The project would have an estimated annual maximum average of 188.3 gigawatt-hours.
