context_page_description: Manapōuri Power Station is an underground hydroelectric power station on the western arm of Lake Manapouri in Fiordland National Park, in the South Island of New Zealand. At 850 MW installed capacity, it is the largest hydroelectric power station in New Zealand, and the second largest power station in New Zealand. The station is noted for the controversy and environmental protests by the Save Manapouri Campaign against the raising the level of Lake Manapouri to increase the station's hydraulic head, which galvanised New Zealanders and were one of the foundations of the New Zealand environmental movement.
  Completed in 1971, Manapōuri was built to supply electricity to the Tiwai Point aluminium smelter near Bluff, some 160 km to the southeast. Later, it was also connected into the South Island transmission network. The station utilises the 230-metre drop between the western arm of Lake Manapouri and the Deep Cove branch of the Doubtful Sound 10 km away to generate electricity.
