The city of Hastings, Minnesota, holds Federal Energy Regulatory Commission (FERC) license 4306, which granted it the authority to design, construct and operate a hydropower facility on the Mississippi River at Lock and Dam 2 in Hastings. The licensed facility consists of a powerhouse, which is adjacent to the dam and contains two 2,200-kilowatt turbine/generators and a power distribution system. The total 4.4-megawatt estimated capacity is enough to provide power to 3,500 households.

FERC issued license 4306 to the city of Hastings on June 10, 1985. Construction began in 1986 and was substantially completed in 1987.
In 2006, Hydro Green Energy, LLC, a private company, approached the city of Hastings with a proposal to expand the capacity of the existing hydropower plant by installing two barge-mounted hydrokinetic generating units downstream of the plant to serve as a pilot project for their hydrokinetic technology.

FERC granted an amendment to the existing license on December 13, 2008. One barge-mounted hydrokinetic unit was installed in early 2009, and Hydro Green was able to demonstrate their operability. The hydropower license has been re-amended, removing the hydrokinetic unit from the project. The hydrokinetic unit has been removed from the site.

The hydropower plant is fully operational. Pertinent correspondence and filings are posted on the FERC eLibrary ( under docket number P-4306.

Licensing of hydropower facilities by the FERC is governed by Part I of the Federal Power Act (FPA), 16 USC 791(a) – 825(r). Coordination between the FERC and the Corps regarding FERC licensing of hydropower at Corps facilities is also governed by a March 30, 2011, memorandum of agreement between the agencies.

A fixed amount, generally $7,000 per year, is funded under the “Investigations” account for FERC-related administrative activities and permit review. Activities such as pre-licensing, coordination during construction and re-licensing are funded under the “Operation and Maintenance” program, and these costs are reimbursed by the licensee to the U.S. Treasury through annual charges by FERC.
