The primary purpose of the dam is hydroelectric power production and it is part of the Chivor Hydroelectric Project. Water from the Batá is diverted by the dam to a power station that discharges to the Lengupá River. The power station supplies 8% of Colombia's power demand.
The Miel I Dam, officially known as the Patángoras Dam, is a gravity dam on La Miel River just south of Norcasia in Caldas Department, Colombia. The dam was constructed between 1997 and 2002 for the primary purpose of hydroelectric power generation. At the time of its completion, the dam was the tallest roller-compacted concrete (RCC) dam in the world but was surpassed by the Longtan Dam in 2009.
The Porce III Dam is an embankment dam on the Porce River 90 kilometres (56 mi) northeast of Medellín in Antioquia Department, Colombia. The dam was constructed between 2004 and 2011 for the primary purpose of hydroelectric power generation.
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 Kazunogawa Pumped Storage Power Station is a pumped-storage hydroelectric power station near Kōshū in Yamanashi Prefecture, Japan. The station is designed to have an installed capacity of 1,600 megawatts (2,100,000 hp) and three of the four 400 megawatts (540,000 hp) generators are currently operational, for a total operational capacity of 1200 MW. Construction on the power station began in 1993 and the first generator was commissioned on 3 December 1999. The second was commissioned on 8 June 2000. The third on become operational on 9 June 2014, six year early due to post-power demand from the Great East Japan earthquake. The fourth and final generator is slate to be commissioned by 2024. It is owned by TEPCO and was constructed at a cost of $2.2 billion USD.
The Entracque Power Plant, also known as The Upper Gesso Plant, is a pumped-storage hydroelectric power station located in Valle Gesso just south of Entracque, Italy. The power station contains pump-generators for two co-located but hydraulically separated power schemes; the Chiotas-Piastra Plant and Rovina-Piastra Plant. Both plants use separate upper reservoirs but use Lago della Piastra as their common lower reservoir. To produce power, water is released from the upper reservoirs to the power station located at the lower reservoir. The pump-generators re-fill the reservoirs and the process repeats as needed. The Chiotas' upper reservoir, Lago del Chiotas, is located much higher in the valley and larger than Rovina's Lago della Rovina which affords it the ability to produce more electricity. The installed capacity of Chiotas is 1,184 megawatts (1,588,000 hp) with a hydraulic head of 1,048 m (3,438 ft) while Rovina has an installed capacity of 133.67 megawatts (179,250 hp) and a head of 598 metres (1,962 ft). Construction on the plant began in 1962 and operations started in 1982. It is owned and operated by Enel.
The Sogamoso Dam is a concrete-face rock-fill dam on the Sogamoso River in northern Colombia. It is located 30 kilometres (19 mi) west of Bucaramanga in Santander Department and 285 kilometres (177 mi) north of Bogotá. The primary purpose of the dam is hydroelectric power generation and its power plant has an installed capacity of 820 megawatts (1,100,000 hp) which increased Colombia's generating capacity by 10 percent.
