Because the project didn’t turn out to be economically feasible, Coastal Hydropower LLC on June 26 notified the Federal Energy Regulatory Commission that it is giving up a preliminary permit for a 6-MW hydro project in Wisconsin.
FERC issued the permit in July 2012, allowing the company to study the feasibility of the proposed Menasha-Neenah Water Power Project, to be located on the Fox River in Winnebago County, Wisc. The Menasha Locks Dam is a federally owned dam operated and maintained by the U.S. Army Corps of Engineers. The Neenah Dam is owned and operated by the Neenah Paper Co. The Menasha and Neenah dams together regulate the surface elevation of Lake Winnebago under the direction of the Corps.
The project would have consisted of the following proposed facilities at the Menasha Locks Dam: eight Very Low Head (VLH), 500-kW turbine units providing a total installed capacity of 4 MW; and a 300-foot-long, 13-kV transmission line. The project would have consisted of the following facilities at the Neenah Dam: four VLH, 500-kW turbines with a total installed capacity of 2 MW; and a 700-foot-long, 12-kV transmission line. The estimated annual generation of the Menasha-Neenah Project would have been 31.5 gigawatt-hours.
The June 26 notice cited a non-continuation of the Investment Tax Credit for hydropower as a key reason why the project didn’t turn out financially.
