Energy Resources rescinds permit apps for hydro projects on the Mississippi River

Energy Resources USA Inc., which lately has filed several applications with the Federal Energy Regulatory Commission for hydroelectric projects, on Sept. 9 filed new such applications.

Then on Sept. 10, the company filed notices with the commission withdrawing all three applications, citing “unforeseeable circumstances.”

Preliminary permits allow three years of project feasibility study without the threat of a competing project at the same site. A license application would then be needed to take the project to the next level. The Sept. 9 permit applications covered:

Lock and Dam No. 5 Hydroelectric Project 

The proposed Lock and Dam No. 5 Hydroelectric Project will be located on the Mississippi River at navigation mile 738.1, about 5 miles northeast of Fountain City, Wisconsin. The project will utilize the existing dam. The lock and dam was completed in 1935 and is owned and operated by the U.S. Army Corps of Engineers for the purposes of navigation.

A new reinforced concreted powerhouse will be constructed downstream of the existing overflow bank adjacent to the right riverbank. The powerhouse will contain the turbine-generators, switchgear, controls, and ancillary systems, as well as shop and storage space. Four vertical Kaplan turbine-generators rated at 1.5 MW each will be installed in the new powerhouse for a total capacity of 6 MW. An 8 MVA 4.16/115 kV three-phase step-up transformer will be located adjacent to the powerhouse in a new substation.

The applicant has identified existing transmission infrastructure in the proposed project area. These existing transmission elements will be evaluated during the permit period through field investigations and discussions with the local utility. It is anticipated that the project will utilize a single overhead three phase, 115kV line which is approximately six miles in length, from the substation to the potential interconnection point. The potential interconnection point is an existing T-line 115 kV.

Lock and Dam No. 7 Hydroelectric Project 

The proposed Lock and Dam No. 7 Hydroelectric Project will be located on the Mississippi River at navigation mile 705.5, about 5 miles northwest of La Crosse, in La Crosse County, Wisconsin. The project will utilize the existing dam. The lock and dam was completed in 1937 and is owned and operated by the Corps of Engineers for the purposes of navigation.

A new reinforced concreted powerhouse will be constructed downstream of the existing overflow bank adjacent to the right riverbank. The powerhouse will contain the turbine-generators, switchgear, controls, and ancillary systems, as well as shop and storage space. Four vertical Kaplan turbine-generators rated at 1 MW each will be installed in the new powerhouse for a total capacity of 4 MW.

A 5 MVA 4.16/115 kV three-phase step-up transformer will be located adjacent to the powerhouse in a new substation. The applicant has identified existing transmission infrastructure in the proposed project area. These existing transmission elements will be evaluated during the permit period through field investigations and discussions with the local utility. It is anticipated that the project will utilize a single overhead three phase, 115kV line which is approximately 2 miles in length, from the substation to the potential interconnection point. The potential interconnection point is an existing T-line 115 kV.

Lock and Dam No. 8 Hydroelectric Project

The proposed Lock and Dam No. 8 Hydroelectric Project will be located on the Mississippi River at navigation mile 679.2, about one mile southwest of Genoa, in Houston County, Minnesota. The project will utilize the existing dam. The lock and dam was completed in 1937 and is owned and operated by the Corps for the purposes of navigation.

A new reinforced concreted powerhouse will be constructed downstream of the existing overflow bank adjacent to the right riverbank. The powerhouse will contain the turbine-generators, switchgear, controls, and ancillary systems, as well as shop and storage space. Four vertical Kaplan turbine-generators rated at 0.875 MW each will be installed in the new powerhouse for a total capacity of 3.5 MW.

A 4 MVA 4.16/115 kV three-phase step-up transformer will be located adjacent to the powerhouse in a new substation. The applicant has identified existing transmission infrastructure in the proposed project area. These existing transmission elements will be evaluated during the permit period through field investigations and discussions with the local utility. It is anticipated that the project will utilize a single overhead three phase, 115kV line which is approximately 0.01 miles in length, from the substation to the potential interconnection point. The potential interconnection point is an existing T-line 115 kV.
