The Federal Energy Regulatory Commission on Dec. 28 granted a Sept. 2 application from Energy Resources USA Inc. for a three-year preliminary permit to study the feasibility of the proposed Lock and Dam No. 22 Hydroelectric Project.
It would be located at the existing Mississippi River Lock and Dam No. 22 on the Mississippi River, near the City of Hannibal in Ralls County, Missouri, and Pike County, Illinois. The Mississippi River Lock and Dam No. 22 is owned by the United States government and operated by the U.S. Army Corps of Engineers.
The project would consist of: a new 770-foot-long by 300-foot-wide earthen intake area; a new 220-foot by 90-foot reinforced concrete powerhouse containing four 2-MW Kaplan hydropower turbine-generators having a total combined generating capacity of 8 MW; one new 1,000-foot-long by 220-foot-wide tailrace; a new 85-foot-long by 43-foot-high by 3-foot-thick intake retaining wall and a new 40-foot-long by 43-foot-high by 3-foot-thick tailrace retaining wall; a new 60-foot-long by 50-foot-wide substation; and a new 6.54-mile-long, 115-kV transmission line. It would have an estimated annual generation of 66.4 gigawatt-hours.
During the course of the permit, the commission expects that the permittee will carry out prefiling consultation and study development leading to the possible development of a license application. The prefiling process begins with preparation of a Notice of Intent and Pre-Application Document. The permittee must use the Integrated Licensing Process unless the commission grants a request to use an alternative process.
