Bear Swamp facility is situated on the Deerfield River in Massachusetts
and includes the Bear Swamp Pumped Storage Plant and Fife Brook
Station. With a generating capacity of 573 megawatts and the ability
to start up quickly in response to power demand, the pumped storage
plant provides an important supply of electricity during times of
peak energy use.
The pumped storage facility is located in Rowe, Massachusetts.
Fife Brook Dam forms the lower reservoir for Bear Swamp. Located
in Florida, Massachusetts, it is a conventional hydroelectric station
and provides 10 megawatts of capacity.
The facility's grounds include an area managed as a state tree
farm, as well as popular recreational spots, such as the Dunbar
Picnic Area and places for fishing and whitewater boating below
Fife Brook Station.
TECHNOLOGY AND ENVIRONMENTAL PERFORMANCE
The Bear Swamp facility uses two reservoirs to store and harness
power for peak electricity needs. Water released from the man-made
upper reservoir falls almost 770 feet through tunnels inside of
the mountain to the lower reservoir, driving two reversible turbines
in the powerhouse.
At night, when electricity demand is lower, the turbines are reversed
and water is pumped back to the top reservoir — ready for
the next day.
OWNERSHIP AND MANAGEMENT
The Bear Swamp facility is managed and operated by an affiliate
of National Energy & Gas Transmission, Inc.
