Eagle Creek and Minnesota Power
This tour features two historic facilities on the Mississippi River northwest of Minneapolis.
The 9.5-MW Sartell project was built between 1905 and 1908 to supply mechanical power for grinders at the Watab Paper Mill. The mill was shut down after an explosion and fire in 2012, and Eagle Creek Renewable Energy restored operations at Sartell the day after the acquisition was closed in 2014.
The 4.5-MW Little Falls facility has a long and storied history. Several dams were built at the site, including one in 1888. The fourth dam at the site was completed in 1921, along with a new powerhouse with three turbine-generator units.

Xcel Energy, St. Anthony Falls Lab and Brookfield
This tour explores the power of St. Anthony Falls, on the Mississippi River in the heart of downtown Minneapolis. Attendees will visit the 13.9-MW Upper St. Anthony Falls plant, St. Anthony Falls Laboratory, and the 10-MW Lower St. Anthony Falls Lock and Dam facility.
Upper St. Anthony Falls was built in 1882 at the site of early sawmills to power arc lights. The original dam was replaced in 2000 and 2001 with a new dam about 30 feet upriver.
St. Anthony Falls Laboratory (SAFL) is an interdisciplinary fluid mechanics research and educational facility at the University of Minnesota. SAFL has a long history in hydropower research and has broadened its focus to encompass emerging water power technologies based on marine and hydrokinetic devices.
Commercial operations were achieved at Lower Saint Anthony Falls Lock and Dam in December 2011. The facility features 16 StrafloMatrix turbine-generators, the first U.S. installation of this technology. StrafloMatrix combines the turbine and generator into a single piece of equipment.

Brookfield Renewable Energy
Brookfield Renewable Energy Partners acquired the Twin Cities hydroelectric facility from Ford Motor Company in 2008. The U.S. Army Corps of Engineers finished the dam in 1917, and Henry Ford built the plant in Saint Paul, Minn., on the promise of cheap hydropower. The run-of-river plant was completed in 1924 at a cost of about $1 million. It has a capacity of 18 MW from a powerhouse with four Francis turbine-generating units.
