The Akosombo Dam, also known as the Volta Dam, is a hydroelectric dam on the Volta River in southeastern Ghana in the Akosombo gorge and part of the Volta River Authority. [1] The construction of the dam flooded part of the Volta River Basin and led to the subsequent creation of Lake Volta. Lake Volta is the largest man-made lake in the world ...
The balance of Ghana's electricity was produced by diesel units owned by the Electricity Corporation of Ghana, by mining companies, and by a 160MW hydroelectric plant at Kpong, about 40 kilometers downstream from Akosombo. A third dam at Bui on the Black Volta River had been studied, and was completed in 2013. [7]
The Akosombo Dam produces 912 MW of electricity for the country, as well as for export to Togo, Benin, and other nearby countries to earn foreign exchange. [1] Lake Volta is also important for transportation, providing a waterway for both ferries and cargo watercraft. Since the huge lake lies in a tropical area, the water remains warm year ...
The VRA was established by the Volta River Development Act, Act 46 of the Republic of Ghana on 26 April 1961. [2]The main purpose of the VRA is to generate and supply electricity for Ghana's needs.
High-capacity electricity generation Akosombo Hydroelectric Project contains three main tributaries: the Black Volta; the White Volta and the Red Volta and the Akosombo Hydroelectric Project flows into the Gulf of Guinea on the Atlantic Ocean. [4] The Akosombo Dam was completed in 1965 as part of the Volta River Project.
In 1961, Kaiser Aluminum & the Ghana Government invested in the Akosombo Hydroelectric Project to provide energy for its aluminum smelters. The company had negotiated favorable terms for power purchase with the government. The agreement was re-negotiated in 1985, by the Rawlings government, to reflect the increased value of electrical energy. [1]
The dam's power plant generates electricity for the Volta River Authority, and the reservoir also provides water transport routes. It is a resource for irrigation and fish farming. The depth of the river is about 45 feet (14 m) below Lake Volta. The Volta River is crossed by the Adome Bridge just below the Akosombo Dam.
To give perspective: in 2011, per the same Energy Commission, the largest Akosombo hydroelectric dam in Ghana alone produced 6,495 GWh of electric power and, counting all Ghana's geothermal energy production in addition, the total energy generated was 11,200 GWh in that year. [52]
