Green Mountain Power Little River Hydroelectric Upgrades
Bringing new capabilities to Vermont’s tallest dam.
PC’s Special Projects Group completed this complex dam improvement project at the Green Mountain Power Little River Hydroelectric facility at the base of the Little River Reservoir. The project included the installation of a 60-inch bypass line and two flow modulating fixed cone valves to allow GMP to operate the plant as a “run of river” facility. The work resulted in improved plant efficiency, increased dam safety measures, and better conditions for fish downstream of the dam.
Work also included the rebuild of the substation, including new foundations, buried conduit and trenches, transformer, backup generator, propane storage tank, and perimeter fencing.
The culmination of nearly eight-month effort was the re-installation of the refurbished runner and bringing the station back on-line in time for spring runoff.
