Woronoco Hydroelectric Project is located at river mile 18.5 on the Westfield River in, Russell, Massachusetts. The Westfield River originates in North-Western Massachusetts and flows 78.1 miles to its confluence with the Connecticut River in West Springfield. The Project’s operating license from the Federal Energy Regulatory Commission (“FERC”) was issued on April 30, 2002.
|LIHI Certificate No.||68|
|LIHI Certificate Term||January 28, 2015 – January 28, 2020

|Owner||Woronoco Hydro, LLC, a subsidiary of Eagle Creek Renewable Energy, LLC|
|Location||Located at river mile 18.5 on the Westfield River in Russell, Massachusetts.|
|Installed Capacity||2.68 MW|
|Average Annual Generation||11,359 MWh|
|FERC No.||P-2631 issued 2002, expires 2042|
The project’s principal features consist of:
- two non-contiguous dam sections and an earthen dike;
- a penstock intake area leading to a powerhouse, which contains three turbine/ generator units with an installed capacity of 2.68 MW;
- a downstream fish passage facility and three upstream eel ladders;
- a 43-acre impoundment at the normal pool elevation; and,
- a bypassed reach with three channels, varying in length from 200 to 1,000 feet.
According to the FERC license for this project, there are three generating units installed. When the license was issued in 2002, the project operated with only one unit (Unit 3, which has a rated installed capacity of 1.9 MW with 30″ flashboards). As part of its relicense application, the applicant proposed to rehabilitate the two non-operating low flow units (Units 1 and 2), which have a rated installed capacity of 0.4 MW each. With the rehabilitated units and flashboards, the project would generate at its full capacity of 2.7 MW and, with the Applicant’s proposed minimum flow, would generate an estimated average of about 11,359 megawatt-hours (MWh) of electricity annually.
The FERC license says the project will continue to be, operated in a run-of-river mode, such that outflows from the project are approximately equal to the sum of the inflows to the project impoundment on an instantaneous basis. Woronoco Hydro would operate the project to minimize fluctuations to the impoundment water surface elevation.
February 24, 2020: The Low Impact Hydropower Institute has received a complete application for Low Impact Recertification of the Woronoco Hydroelectric Project.
