Location/Description
|
Northern States Power Company (a.k.a. Xcel Energy) holds Federal Energy Regulatory Commission license number 2056, granting it the authority to operate the hydropower facility located at Upper St. Anthony Falls.
The hydropower facility includes a transition wall extending from the Corps' lock structure; a horseshoe dam, spillway and roll dam located across the river and several earthen and concrete dams at various locations to control water flows; a main powerhouse, located on Hennepin Island; two underground transmission lines connected to the Main Street substation; and several abandoned hydropower structures that are still listed on the license. The powerhouse includes five turbines with a total capacity of 12.4 megawatts.
|
Background
|
The original hydropower license was granted on Sept. 6, 1951, to the St. Anthony Falls Water Power Company. The license was transferred shortly thereafter to Northern States Power Company. The original license included a 16-megawatt "lower development" hydropower facility at Lower St. Anthony Falls. In 1956, a 12.4-megawatt "upper development" hydropower facility at Upper St. Anthony Falls was added to the license. In 1987, the Lower Development hydropower plant failed and has since been abandoned. The licensee appealed to FERC in 2001 to remove the lower development from the license. The license was reissued on March 8, 2004, for a period of 30 years and only includes the 12.4-megawatt Upper Development.
In December 2003, FERC, the Advisory Council on Historic Preservation and the Minnesota State Historic Preservation Officer signed a programmatic agreement for managing the historic properties affected by the hydropower license.
|
Status
|
The hydropower facility continues to be owned and operated by Northern States Power (a.k.a. Xcel Energy). FERC conducts safety inspections yearly. Safety inspections sometimes require drawdown of the intermediate pool between the upper and lower dams to inspect the tailrace area.
Pertinent correspondence and filings are posted on the FERC eLibrary (http://elibrary.ferc.gov) under docket number P-2056.
|
Authority
|
Licensing of hydropower facilities is governed by Part I of the Federal Power Act (FPA), 16 U.S.C. §§ 791(a) – 825(r). Licensing at Corps facilities is also governed by a 1981 Memorandum of Understanding between FERC and the Department of the Army.
