Symphony Hydro LLC applied March 20 at the Federal Energy Regulatory Commission for a preliminary permit on a hydroelectric project to be located in Minneapolis, Minn., on the Mississippi River.
This permit would allow three years of feasibility work without any competing applications being filed. The project site is at the U.S. Army Corps of Engineers’ existing Upper St. Anthony Lock and Dam. A concrete overflow spillway at the dam is owned by Xcel Energy, the application noted. There is also a licensed but unconstructed Crown Hydro LLC project at this location.
Symphony noted that FERC recently rejected a prior application for its project, but it said it has met since then with the Corps to ease any concerns that its project will interfere with the Corps’ flood control work at this dam.
The company plans two turbine-generators at the site with a combined capacity of 3.4 MW, to interconnect into the Xcel transmission system.
