Hydroelectric power — water power — at one time supplied
a majority of New England's energy needs. Although hydropower in Northeast
Utilities' (NU's) service area cannot meet all the power demands of today's
customers, NU relies on hydropower for a small percent of its customers'
electrical energy requirements.
NU operates 27 run-of-river or "conventional hydro" stations, normally
during periods of high electricity demand. These stations are mainly on the Merrimack, Pemigewasset and Androscoggin Rivers
in New Hampshire.
The NU conventional hydro system also plays an important role in the
effort to restore anadromous fish, such as the Atlantic salmon and the
American shad, to New England's waterways. Fish passageway facilities
have been installed at seven hydro stations, including five in New Hampshire.
