Holyoke Gas & Electric – Hadley Falls – December 2014

Ivyland, PA – American Governor Company (AGC) has been awarded a contract by Holyoke Gas & Electric to design, manufacture, and install the digital governor retrofit on Unit #2 at its Hadley Falls Hydro Station. This 15.5MW vertical unit was placed into service in 1984 and is presently controlled by a Woodward Mod II Analog Electric Governor. The unit will begin an outage in July 2015 with a Return To Service scheduled for August 2015.

Holyoke Dam is a 30-foot granite dam that spans the Connecticut River between the towns of Holyoke and South Hadley, Massachusetts. The dam was constructed between 1895 and 1900, and diverts water from the river into the Holyoke Canal System and HG&E’s Hadley Falls Facility. The Hadley Falls site also contains the Robert E. Barrett Fishway to help migrating fish over the dam. This fish lift was the first and most successful fish lift on the Atlantic coast.
