The Lockwood project, located on the Kennebec River, is a seven unit hydroelectric project with 20 feet of gross head and is the first dam on a river undergoing anadromous fish restoration. The project was required to provide upstream passage facilities, including interim trap and transport facilities, for the passage of American shad, Atlantic salmon and river herring. Florida Power & Light Energy Maine (FPLE) had developed the conceptual design for the fish lift facility but sought an assessment of lower cost alternatives.
Kleinschmidt conducted a feasibility study and review of FPLE’s conceptual designs (and other proposed designs) and developed a cost effective alternative solution. Subsequently, Kleinschmidt provided final design services, prepared permit applications, and assisted in construction monitoring and contract negotiations. Kleinschmidt also provided all programming and graphic controls for the automated facility. The main elevator system consists of a combined hopper and crowder system which reduces required mechanical devices and electrical controls. The unique main hopper is equipped with a pivotable center floor to allow fish to be discharged from multiple locations within the hopper. This hopper feature permitted the trap and transport equipment to be relocated for easier truck access.
Kleinschmidt developed a facility design that resulted in a 20% savings in initial construction costs and reduced annual operational costs compared to FPLE’s initial design.
