The Hennepin Island Hydroelectric Plant is at St. Anthony Falls in Minneapolis, Minnesota.

The facility stands on Hennepin Island near the Pillsbury "A" Mill at Saint Anthony Falls, the river's only major waterfall, which powered the city's early sawmills, grist mills and other industry.

[1][2] NSP/Xcel renewed its license which was authorized by the Federal Energy Regulatory Commission in March 2004.

One condition of the license is the creation of a recreation area to show the evolution of St. Anthony Falls.

In 2008, NSP/Xcel collaborated with the University of Minnesota's St. Anthony Falls Laboratory on 'StreamLab', an 'experimental stream channel and floodplain system'[3] which improves two existing flood bypass channels to study the site's ecology and hydrology.
