Hydroelectric power development rights on the river were acquired by the British Newfoundland Development Corporation (Brinco) in the 1950s. In partnership with Wabush Mines Limited and the Iron Ore Company of Canada, the two mining corporations operating in Western Labrador, Brinco created the Twin Falls Power Corporation to deliver power west to the two mining operations being developed near the Labrador-Quebec border. Construction of the Twin Falls power station began in 1960 and was located at the base of a high dry river canyon adjacent to the Unknown River. The river was dammed at Twin Falls to form a reservoir (Ossokmanuan Reservoir), raising the water to the height of the old channel's escarpment. When finished in 1963, the station had a total capacity of 225 MW with two long transmission lines at 230,000 volts (or 230 kV), with remote switching at the far end from the station. It was a masterpiece of hydroengineering constructed at a cost of $47.5 million (1963). Twin Falls power was essential to the later power development at Churchill Falls. It helped open up the area and supplied the power required during the construction phase of the project. In the planning stage, however, it became apparent that greater efficiency in the production of electricity could be achieved by diverting the flow of water from the Ossokmanuan Reservoir into the Smallwood Reservoir. 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 closed and the water diverted into the Smallwood Reservoir under an agreement with Churchill Falls Labrador Corporation Limited (CFLCo). == External links == * (Satellite twinfallsphoto ) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Twin Falls (Newfoundland and Labrador)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
