It is owned and operated by Tractebel Energia and produces the equivalent of 60% of the energy consumed in Santa Catarina.
The São Simão Dam is an embankment dam on the Paranaíba River near São Simão in Goiás/Minas Gerais, Brazil. It was constructed for hydroelectric power production and flood control. The dam was completed in 1978 and all generators were operational by 1979. In 1977, the first use of roller compacted concrete in Brazilian dam construction occurred on the São Simão.
The Três Marias Dam, also known as Bernardo Mascarenhas, is an embankment dam on the São Francisco River near Três Marias in Minas Gerais, Brazil. It was constructed for hydroelectric power production and flood control. The dam was completed in 1961 and its first generator was operational in 1962. The dam's power plant is named after Bernard Mascarenhas who in 1889, built South America's first major hydroelectric power plant in Brazil, the Marmelos Zero Power Plant.
The Srinagarind Dam is an embankment dam on the Khwae Yai River in Si Sawat District of Kanchanaburi Province, Thailand. The purposes of the dam are river regulation and hydroelectric power generation. The dam's power station has a 720 megawatts (970,000 hp) capacity of which 360 megawatts (480,000 hp) is pumped storage. The dam was named after Princess Srinagarindra.
The Shin-Takasegawa Pumped Storage Station (新高瀬川発電所) uses the Takase River to operate a pumped storage hydroelectric scheme about 12 kilometres (7.5 mi) west of Ōmachi in Nagano Prefecture, Japan. Part of the system is within Chūbu-Sangaku National Park.
The Bailianhe Pumped Storage Power Station is a pumped-storage hydroelectric power station located 58 kilometres (36 mi) east of Huanggang in Hubei Province, China. It was constructed between 2004 and 2010 and has a 1,200 megawatts (1,600,000 hp) installed capacity. The power station operates by shifting water between an upper and lower reservoir to generate electricity. For this project, only the upper reservoir had to be created as an existing reservoir, the Bailianhe Reservoir, was used as the lower. During periods of low energy demand, such as at night, water is pumped from Bailianhe Reservoir up to the upper reservoir. When energy demand is high, the water is released back down to the lower reservoir but the pump turbines that pumped the water up now reverse mode and serve as generators to produce electricity. The process is repeated as necessary and the plant serves as a peaking power plant.
Irapé Dam, the tallest dam in Brazil, is an embankment dam on the Jequitinhonha River in the state of Minas Gerais. It is on the border of Berilo and Grão Mogol districts, about 26 kilometres (16 mi) west of Virgem da Lapa. The dam was constructed between 2002 and 2006 for the purpose of hydroelectric power generation.
The Kindaruma Hydroelectric Power Station, also Kindaruma Dam is an embankment dam with two gravity dam sections on the Tana River in Kenya. It straddles the border of Embu and Machakos counties in Kenya. The primary purpose of the dam is hydroelectric power generation and it supports a 72 megawatts (97,000 hp) power station. It is Kenya's first post-independence hydroelectric power plant. It was commissioned in 1968 as part of the Seven Forks Scheme. The power station is operated by Kenya Electricity Generating Company.
The Garafiri Dam is an embankment dam on the Konkouré River which forms the boundary between the Kindia and Mamou Regions of Guinea. The dam was constructed by Salini Impregilo between 1995 and 1999 for the purpose of hydroelectric power generation and water supply. The power station had a breakdown in 2002 but was repaired shortly afterwards. The power station has an installed capacity of 75 megawatts (101,000 hp).
The Banieya Dam is an embankment dam on the Samou River in the Kindia Region of Guinea. It is located 16 km (9.9 mi) west of Kindia. The dam was completed by 1969 for the purpose of water supply. A hydroelectric power station of 5.2 megawatts (7,000 hp) was commissioned at the dam's toe in 1988. The Kale Dam, which also supports a hydroelectric power station, is located downstream.
The Bumbuna Dam is a concrete-face rock-fill dam on the Seli River near Bumbuna in Tonkolili District, Sierra Leone, and 350 kilometres (220 mi) from the capital of Freetown, the main consumer. The country's first hydroelectric dam, it supports a 50-megawatt (67,000 hp) power station.
The Colíder Dam is a rock-fill dam with an asphalt-concrete core, built from 2011 to 2019 on the Teles Pires river. It is located about 40 km (25 mi) southeast of Colíder in the state of Mato Grosso, Brazil. The dam's hydroelectric power stations have 3 turbines each 102.3 MW, resulting in a total installed capacity of 306.9 MW. Construction on the run-of-the-river type station was initiated in May 2011, and the last unit started operating in December 2019.
