The Federal Energy Regulatory Commission on June 2 issued a notice about a March application from Symphony Hydro LLC for a preliminary permit proposing to study the feasibility of the Symphony Hydro Project, to be located at the existing Upper St. Anthony Lock and Dam on the Mississippi River, near the city of Minneapolis in Hennepin County, Minnesota.
The Upper St. Anthony Lock and Dam is owned and operated by U.S. Army Corps of Engineers. The sole purpose of a preliminary permit, if issued, is to grant the permit holder priority to file a license application during the permit term.
The proposed project would consist of: the existing 400-foot-long by 56-foot-wide by 77-foot-high lock; two new 56-foot-wide by 70-foot high vertical lift steel gates; two new submersible 1,700-kW axial flow Kaplan turbine-generator units having a combined capacity of 3.4 MW; two new 6-foot-long by 6-foot-wide by 4-foot-high pad mounted metal boxes containing plant controls, communications and inverter equipment, and a step-up distribution transformer; and a new 400- to 500-foot-long, 13.8 kV underground transmission line that would connect to Xcel Energy’s distribution system. The project would have an estimated annual generation of 18,500 megawatt-hours.
The applicant contact is: Robert H. Schulte, 2236 Coley Forest Place, Raleigh, NC 27607, (952) 949-2676.
