Churchill Falls Generating Station

45: 653:, opened in 1963, 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 780:, but has resulted in significant damage to their traditional territory. The plant caused flooding of over 5,000 km (1,900 sq mi), which damaged the habitats of many animals, disrupted caribou migratory routes, and drowned wildlife such as beavers. Furthermore, Innu burial sites and hunting grounds were destroyed, causing irreparable damage to the traditions and livelihoods of the Innu people. A 2016 study commissioned by the 815:. The amount represents approximately 5% of Hydro-Quebec's estimated $ 80 billion (CAD) profits over the 50-years that the hydro-electric plant has been in operation. Furthermore, the Innu Nation have united with First Nations in Canada and the United States to oppose Hydro-Québec's planned transmission line to Massachusetts. A large portion of the energy for this project would be generated in the Churchill Falls hydroelectric plant. 666: 32: 685:'s natural drainage area covers over 60,000 km (23,000 sq mi). Dyking Orma and Sail lakes brought the total to 72,000 km (28,000 sq mi). Studies showed this drainage area collected 410 mm (16 in) of rainfall plus 391 cm (154 in) of snowfall annually equalling 12.5 cu mi (52 km) of water per year; more than enough to meet the project's needs. 615:. But the only practical solution was to negotiate an agreement with Quebec. By 1969, after 16 years of attempts to finance the project, BRINCO was in dire financial straits whereas Quebec was flush with money, further strengthening Quebec's negotiating position. In the end BRINCO would sell 90 percent of the power to Hydro Quebec, at a fixed price, over 40 years renewable for a further 25. 631: 52: 497: 754:
contract was signed and the court could not force the parties to re-open the contract. Gascon additionally said that unforeseeability would justify overturning the contract only if it made the contract less beneficial to one party and not in this case, where it merely made the contract more beneficial to one party (Hydro-Québec).

516:. The advantage of the site was the river's drop of more than 300 metres in less than 32 km, and steady supply of water. These findings were confirmed in a 1947 survey, but development did not proceed due to the remoteness of the site and the distance from markets for the power. 555:, and inland waterways are under the jurisdiction of provincial, rather than the national government.
