J.A.McDonald, Inc. performed the Glen Hydro, Design / Build, Hydro- Generation project that included the reconstruction of a gravity concrete dam, post tension rock anchors, modern pneumatic operated flashboards, trash racks, gates and 4,000 feet of eight foot diameter penstock which was encased in concrete at one location as it crossed the Mascoma River. Three 140 WTFS turbine-generators, butterfly valves, and switch gear were installed in a new, esthetically designed powerhouse that blended with the surrounding landscape. Electrical and mechanical controls, switching, interconnect, and project function equipment completed this turn-key project.
J.A.McDonald, Inc. welcomes projects that are functionally needed such as power generation systems. Timely performance, within budget, and their ability to supply design and design review services made the Glen Hydro Project another one of J.A.McDonald, Inc.'s successful projects.
