ManapÅuri 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 854 MW installed capacity (although limited to 800 MW due to resource consent limits [ 3 ] ), it is the largest hydroelectric power station in New Zealand, and the second ...
Hydroelectricity is the primary source of renewable energy in New Zealand. Power is generated the most in the South Island and is used most in the North Island. [1] Early schemes such as the Waipori scheme commissioned in 1903 and the Lake Coleridge power station commissioned in 1914 established New Zealand's use of renewable hydro energy.
The Save Manapouri Campaign was launched at a public meeting at Invercargill in October 1969. [2] It later came to manifest the international awareness of the environment that came with the prosperity of the 1960s. "At its simplest, the issue was about whether Lake Manapouri should be raised by as much as 30 metres.
Manapouri Power Station is a single underground power station in Fiordland, and the largest hydroelectric station in the country. It has a maximum generating capacity of 730 MW and produces 4800 GW⋅h annually, mainly for the Tiwai Point aluminium smelter near Invercargill. Both Waitaki and Manapouri are operated by Meridian Energy.
The smelter's power demand from the national grid is about 570 MW. Most of the energy for the smelter is supplied from the Manapouri hydroelectric power station, via two double circuit 220 kV transmission lines. The facility is the largest electricity consumer in New Zealand.
Wave power involves converting the energy in ocean surface waves into electricity using devices either fixed to the shore, the seabed or floating out at sea. Wave energy varies with time, depending on when and where the winds and storms that drive the waves occur. Tidal energy is more regular and predictable.
The Manapouri Hydroelectric Power Station is located on the West Arm of Lake Manapouri, with most of the electricity generated serving the Tiwai Point Aluminium Smelter (which is announced to close at the end of 2024). [4] Workers at the power plant are ferried by boat from Manapouri, as there is no road access to the power station.
A number of commentators [who?] consider that the earliest major environmental issue in New Zealand was the national campaign to prevent the raising of the levels of Lakes Manapouri and Te Anau as part of stage two of the development of the Manapouri Power Project. A "Save Manapouri Campaign" ran from 1959 through to 1962, involving ...
