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 854 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 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.
The Waitaki River is a large braided river that drains the Mackenzie Basin and runs some 209 kilometres (130 mi) south-east to enter the Pacific Ocean between Timaru and Oamaru on the east coast of the South Island of New Zealand. It starts at the confluence of the Ōhau and Tekapo rivers, now at the head of the artificial Lake Benmore, these rivers being fed by three large glacial lakes, Pukaki, Tekapo, and Ōhau at the base of the Southern Alps. The Waitaki flows through Lake Benmore, Lake Aviemore and Lake Waitaki, these lakes being contained by hydroelectric dams, Benmore Dam, Aviemore Dam and Waitaki Dam. The Waitaki has several tributaries, notably the Ahuriri River and the Hakataramea River. It passes Kurow and Glenavy before entering the Pacific Ocean. The River lends its name the Waitaki District on the south side of the river bank.
An underground power station is a type of hydroelectric power station constructed by excavating the major components from rock, rather than the more common surface-based construction methods.
The Rangitaiki River is the longest river in the Bay of Plenty region in New Zealand's North Island. It is 155 kilometres (96 mi) long, and rises inland from northern Hawkes Bay to the east of the Kaingaroa Forest. The Rangitaiki catchment covers an area of 3005 km2. It flows in a generally northeastward direction, passing through the town of Murupara and skirting close to the western edge of Te Urewera National Park before turning northwards, flowing past Edgecumbe and into the Bay of Plenty close to Thornton.

Lake Qaraoun is an artificial lake or reservoir located in the southern region of the Beqaa Valley, Lebanon. It was created near Qaraoun village in 1959 by building a 61 m-high (200 ft) concrete-faced rockfill dam in the middle reaches of the Litani River. The reservoir has been used for hydropower generation, domestic water supply, and for irrigation of 27,500 ha.
The electricity sector in New Zealand uses mainly renewable energy, such as hydropower, geothermal power and increasingly wind energy. As of 2019, 82% of electricity is generated from renewable sources, making New Zealand one of the countries with the lowest carbon dioxide emissions from electricity generation. Electricity demand grew by an average of 2.1% per year from 1974 to 2010 but decreased by 1.2% from 2010 to 2013.
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.
The Ingula Pumped Storage Scheme is a pumped-storage power station in the escarpment of the Little Drakensberg range straddling the border of the KwaZulu-Natal and Free State provinces, South Africa. It is about 22 km (14 mi) North-East of Van Reenen.
The Kaimai hydro power scheme is a hydroelectric power scheme on the Wairoa River in the Bay of Plenty in New Zealand. The scheme is operated by TrustPower. It has four operational power stations, and formerly the McLaren Falls Station which was decommissioned in 1989 following the commissioning of the Ruahihi Station.
The Karapiro Power Station is a hydroelectric power station at Karapiro on the Waikato River, in the North Island of New Zealand. The power station lies on Lake Karapiro, a major rowing regatta venue. Karapiro is 30 kilometres (19 mi) south-east and upstream from the city of Hamilton and several kilometres from Cambridge. It is the last of the eight hydroelectric power stations on the Waikato River.
The Tongariro Power Scheme is a 360 MW hydroelectricity scheme in the central North Island of New Zealand. The scheme is currently operated by electricity generation company Genesis Energy.
The Waitangitāhuna River are two rivers in the West Coast region of New Zealand's South Island. It was a single river until an avulsion in March 1967, when it became two rivers. Since then, the southern portion of the river has flowed into Lake Wahapo, while the northern section discharges into the Tasman Sea north of Ōkārito Lagoon.
The Aniwhenua power station is a hydroelectric power facility in Bay of Plenty in New Zealand located on the Rangitaiki River upstream of the Matahina Power Station. Water is drawn from behind a dam above the Aniwhenua Falls and diverted through a canal and a headpond to the power station before being discharged back into the river. The power station is named after the falls which are adjacent to the power station.
The Matahina power station is a hydroelectric power facility in Bay of Plenty in New Zealand located in the Bay of Plenty on the Rangitaiki River downstream of the Aniwhenua Power Station. The river was dammed to form Lake Matahina from which water is drawn and diverted through the power station before being discharged back into the river. The Matahina dam is the largest earth embankment dam in the North Island of New Zealand.
Lake Wahapo is a small glacial lake in South Westland, New Zealand, within the Westland Tai Poutini National Park and near the township of Whataroa. It was a traditional mahinga kai for local Māori. State Highway 6 skirts the lake's southern shore. The lake discharges to the Ōkārito River via a small hydroelectric power station commissioned in 1960. The ecology of the lake has altered considerably since 1967, when the Waitangitāhuna River changed course to flow into the lake.
