OSTI ID:5713041

This report determines the feasibility of adding hydropower generation to Lock and Dam Number 1, located on the Mississippi River in St. Paul, Minnesota. The existing project consists of a concrete Ambursen-type spillway section, two navigation locks on the right side of the river and an existing 14.4-mw hydro plant on the left side. The Corps owns and operates the dam and locks, while the Ford Motor Company owns and operates the hydro plant. This study shows that an additional powerplant can be built at the project that will more fully utilize the existing river flows. Four alternative powerplant locations were investigated. The selected powerplant will be 7.2-mw, single tubular unit, constructed at the spillway located near the existing powerplant. The new powerplant will produce 21.5 million kWh of annual generation. The total investment cost will be 11.5 million dollars. The project is economically feasibile with a benefit cost ratio of 1.12. The annual production cost will be 48 mills per kWh.
