Twin Falls is the site of a hydroelectric power station developed by the British Newfoundland Development Corporation (Brinco) to deliver power to mining operations in Labrador City and Wabush. Commissioned in 1963, its operation ended in 1974. Utilizing this water at the Churchill Falls plant enabled approximately three times as much electricity to be produced from the same volume of water. 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).
Twin Falls Aerodrome is an abandoned airport located southeast of the Twin Falls Hydroelectric Power Station, in Labrador, Canada.
