Karuma Hydroelectric Power Station
The Karuma Hydroelectric Power Station is an operational 600 MW hydroelectric power station in Uganda. It is the largest power-generating installation in the country.
The power station is located on the Victoria Nile, at the former location of the Karuma Falls. This location is approximately 2.5 kilometres (1.6 mi) upstream of where the Masindi-Gulu Highway crosses the Nile. By road, it is approximately 99 kilometres (62 mi) northeast of Masindi and 75 kilometres (47 mi) south of Gulu.
The electrical-mechanical installations of the power station are located approximately 100 metres (328 ft) underground, with 26.5 kilometres (16 mi) of underground access roads, making Karuma the 14th largest underground power station in the world.
As far back as 1995, the government of Uganda planned to construct a hydropower station at the site of the Karuma Falls. Initially, Norpak, a Norwegian energy company, was awarded the contract to perform the feasibility study and the environmental impact assessment (EIA) for the dam. The World Bank promised to make a loan available to pay for the construction. The feasibility study report was made available in October 2006. Bids for construction of the project went out in November 2006. Initially, the plan was to build a 200-250 megawatt power station.
In 2009, the plans were redrawn, calling for a much larger project of 750 megawatts. In 2009, Norpak pulled out of the negotiations with the Ugandan government, due to the Great Recession.
The Ugandan government then contracted with Energy Infratech Private Limited to perform a new feasibility study and a new EIA, given that a larger power station was now being planned. At that time, construction was expected to start in 2012 and last six years.
In July 2011, media reports indicated that the maximum capacity of the project had been scaled back to 600 megawatts from 750 megawatts. Some international development partners wanted to scale back even further, to a maximum capacity of 400 to 450 megawatts.
Karuma Power Station comprises a roller compacted concrete gravity dam, that measures 20 metres (66 ft) high and 312 metres (1,024 ft) long. There are six water intake towers, each measuring 20 metres (66 ft) high and 29 metres (95 ft) wide. The underground chamber housing the six vertical Francis turbines of 100MW each, measures 200 metres (656 ft) long, 21.3 metres (70 ft) wide, and 53 metres (174 ft) high.
