The Buksefjord hydroelectric power plant is the first and largest hydroelectric power plant in Greenland. It was built by Nuuk-Kraft and it is operated by Nukissiorfiit, Greenland's national energy company. [1]
In 1984–85, Greenland's energy authority prepared a Greenland's hydroelectricity development program. At that time all electricity in Greenland was produced by oil based fuels, but there had been a sharp rise in oil prices in the preceding years. Construction of a plant in Buksefjord was proposed by a private consortium in 1988. In 1989, four companies were invited to a public tender. However, later it was decided that construction of the plant will be financed by the Home Rule of Greenland and the plant will be rented to Nuuk-Kraft consortium. Construction of the plant was approved by the Parliament of Greenland in 1990. [1] It was commissioned in 1993. [2]
Unconventionally, the power station is situated 600 metres (2,000 ft) inside a mountain and it consists of 14 kilometres (8.7 mi) of tunnels. [2] The upper reservoir, Kang Lake, is situated 249 metres (817 ft) above sea level at Buksefjord. Due to damming and deep inlet, it has a total effective volume of 1.9 cubic kilometres (0.46 cu mi), which is six times more than the annual water consumption by the plant. From the lake, a 10.5-kilometre (6.5 mi) long inlet pressure tunnel runs down to the plant. [1]
Originally, the plant had two turbines with capacity of 15 MW each. In 2008, a third turbine with the same capacity was installed. [2] [3]
The generated power is transferred to Nuuk over the 57-kilometre (35 mi) long Buksefjord–Nuuk power line, which includes the Ameralik Span, the world's longest span. [1] [3]
Nuuk is the capital of and most populous city in Greenland, an autonomous territory in the Kingdom of Denmark. Nuuk is the seat of government and the territory's largest cultural and economic center. The major cities from other countries closest to the capital are Iqaluit and St. John's in Canada and Reykjavík in Iceland. Nuuk contains a third of Greenland's population and its tallest building. Nuuk is also the seat of government for the Sermersooq municipality. In January 2024, it had a population of 19,872. Nuuk is considered a modernized city after the policy began in 1950.
Lake Vidraru is an artificial lake in Romania. It was created in 1965 by the construction of the Vidraru Dam on the Argeș River.
The Ameralik Span is the longest span of an electrical overhead power line in the world. It is situated near Nuuk on Greenland and crosses Ameralik fjord with a span width of 5,376 m (17,638 ft) at 64°6′18″N51°14′16″W. It was built in 1993 by the Norwegian company NTE Entreprise and is part of a single-circuit 132 kV powerline running from Buksefjord hydroelectric power plant to Nuuk.
Guthega Power Station is located in the Snowy Mountains region of New South Wales, Australia. The power station's purpose is for the generation of electricity. It is the first to be completed and smallest of the initial seven hydroelectric power stations that comprise the Snowy Mountains Scheme, a vast hydroelectricity and irrigation complex constructed in south-east Australia between 1949 and 1974 and now run by Snowy Hydro.
The Catagunya Power Station is a run-of-the-river hydroelectric power station located in the Central Highlands region of Tasmania, Australia. The power station is situated on the Lower River Derwent catchment and is owned and operated by Hydro Tasmania.

The Narva Power Plants are a power generation complex in and near Narva in Estonia, near the border with Leningrad Oblast, Russia. The complex consists of the world's two largest oil shale-fired thermal power plants, Eesti Power Plant and Balti Power Plant. In 2007, Narva Power Plants generated about 95% of total power production in Estonia. The complex is owned and operated by AS Narva Elektrijaamad, a subsidiary of Eesti Energia.
The Caruachi Dam is a concrete gravity dam on the Caroní River in Bolivar state, Venezuela. It supports a hydroelectric power facility with a 2,160 megawatts (2,900,000 hp) capacity. It is about 59 kilometres (37 mi) downstream from the Guri Dam belonging to the Central Hidroeléctrica Simón Bolívar, and about 35 kilometres (22 mi) from where the Caroni and Orinoco rivers meet at Ciudad Guayana.
Sisimiut Hydro Power Plant is a hydroelectric power plant near Sisimiut, Greenland. Construction started in March 2007 and the plant was commissioned on 7 April 2010. The initial capacity of the power plant is 15 MW. The construction included 3,000 cubic metres (110,000 cu ft) of concrete constructions, a blasted tunnel with length of 4,700 metres (15,400 ft) and a pressure pipe with length of 400 metres (1,300 ft). The altitude difference is 78.6 metres (258 ft). Produced electricity is transferred to Sisimiut by new 27.4 kilometres (17.0 mi) long 60 kV high voltage lines.
The Coleridge Power Station is a hydroelectric facility at Lake Coleridge on the Rakaia River in Canterbury, New Zealand. The power station is owned and operated by Manawa Energy.
The Cahora Bassa Dam is located in Mozambique. It is one of two major dams on the Zambezi river, the other being the Kariba. The project began to come online in 1979 after much political debate. This dam uses the Zambezi River water to generate electricity by turning turbines. That energy is then sent to South Africa. The Cahora Bassa Dam forms Cahora Bassa Lake. The dam is jointly owned by Mozambique and Portugal. From independence until 2007, eighteen percent share of the dam and lake was owned by Mozambique and eighty-two percent by Portugal. Portugal sold down its share to 15 percent in 2007. The Cahora Bassa Dam is the largest hydroelectric power plant in southern Africa and the most efficient power generating station in Mozambique.

The plant has an installed capacity of 460 MW, making it the second largest power plant in the country. It is also expected to help provide water for the irrigation of 140,000 ha. It was inaugurated in May 2010 and the last generator became operational in February 2012. Its construction was negatively perceived by downstream Egypt.
