Hydroelectric power in New Zealand has been a part of the country's energy system for over 100 years and continues to provide more than half of the country's electricity needs. 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. By the early 1950s, over 1,000 megawatts (1,300,000 hp) of installed capacity was from hydro energy. By the early 1960s, most North Island hydro sites had been developed while the South Island still had many potential sites. The commissioning of the HVDC Inter-Island link in 1965 made it possible to send large amounts of electricity between the two islands, and from that time hydro capacity in the South Island increased rapidly. Major developments included the 540 MW Benmore Power Station (1966), the 700 MW Manapouri power station (1971), the 848 MW Upper Waitaki River Scheme (1977–85) and the 432 MW Clyde Dam (1992). By the mid-1990s, hydro capacity had reached over 5,000 MW, and remains around this level today.
In New Zealand, hydropower accounts for 55% of electricity production, ranking it as the fifth-largest contributor among International Energy Agency (IEA) member nations.[2][3]
