Free Flow Power looks at feasibility of 17 MW Mississippi River hydro project

On Jan. 2, Free Flow Power Iowa 1 LLC filed an application with the Federal Energy Regulatory Commission for a preliminary permit to study the feasibility of the Mississippi Lock and Dam 12 Water Power Project (Mississippi L+D 12 Project).

The project would be located at the existing U. S. Army Corps of Engineers Mississippi River Lock and Dam No. 12 near the City of Bellevue, Jackson County, Iowa. The sole purpose of a preliminary permit, if issued, is to grant the permit holder priority to file a license application during the permit term, FERC said in a notice to be published in the April 3 Federal Register about this application.

The proposed project would consist of the following new facilities:

  • a powerhouse located at the east end of the movable section of the dam and containing six horizontal bulb turbines with a total nameplate capacity of 17.06 MW; and
  • a 69-kV, 4,940-foot-long overhead transmission line connecting the project generation with Alliant Energy transmission facilities.

The majority of the project would be located on lands owned by the federal government and operated by the Corps. The estimated annual generation of the Mississippi L+D 12 Project would be 85.4 gigawatt-hours.

The applicant is a project affiliate of Free Flow Power Corp. out of Boston, Mass.
