The US Federal Energy Regulatory Commission (FERC) has issued its first full license for an in-stream hydro-kinetic power project. The project will be located on the Mississippi River, in the output channel of a hydro-power dam operated by the City of Hastings, Minnesota (as pictured).

Hydro Green Energy will provide two, 100kW turbines, giving a 70-kilowatt boost in to a pre-existing 4.4-megawatt Mississippi River hydro-power facility. Hence, the permit is really an amendment to the existing license. Details are presented below.Below is a shot of one of the two turbines, as assembled (in the USA), during the fall of 2008.

The two turbines will be suspended from a barge, which is cable held in the tail water of an existing dam. The turbines will drive their respective generators, which are mounted atop the barge. A license requirement, should adverse environmental impacts occur, is for the city to modify operations or remove the turbines or generator barge.
FERC outlines the hydro-kinetic facility permitting process here.
Because this will the the first such operating facility, it will be scrutinized for impacts, on spawning fish particularly. The important native species include the shovelnose sturgeon, paddlefish, walleye, and sauger. (They can chop up all the asian carp they want to and people will cheer.)
