Twin Falls is the site of a hydroelectric power station developed by the British Newfoundland Development Corporation (Brinco) to deliver power[1] to mining operations in Labrador City and Wabush.

When finished in 1963, the station has a total capacity of 225 MW with two 115-mile (185 km) long transmission lines at 230,000 volts (or 230 kV).

It helped open up the area and supplied the power required during the construction phase of the project.

In July 1974 the Twin Falls plant was put into extended shutdown and the water diverted into the Smallwood Reservoir under an agreement with Churchill Falls Labrador Corporation Limited (CFLCo).
