Stiegler's Gorge Hydroelectric Power Station (SGHPS), is a planned 2,100 megawatts (2,800,000 hp) hydroelectric dam in Tanzania.[1] The power station is expected to produce 5,920GWh of power annually.[2]


The power station would be located across the Rufiji River, in the Stiegler's Gorge, in the Selous Game Reserve, Morogoro Region, approximately 220 kilometres (137 mi), by road, southwest of Dar es Salaam, the commercial capital and largest city of Tanzania.[3]

This power station is located in Selous Game Reserve, one of the world's largest World Heritage sites, measuring 45,000 square kilometres (17,000 sq mi). The power station and reservoir lake are planned to occupy approximately 1,350 square kilometres (520 sq mi), within the game reserve.[1]


The government of Tanzania has been considering establishing this power station since the 1960s. When fully developed, it will be the largest power station in Tanzania. The 134 metres (440 ft) arched, concrete dam is expected to create a reservoir lake, 100 kilometres (62 mi), in length, measuring 1,200 square kilometres (460 sq mi), with 34,000,000,000 cubic metres (1.2×1012 cu ft) of water.[1]


In August 2017, the Tanzanian government advertised for bids to construct this dam. The selected contractor is expected to complete the dam in no more than 36 months.[4][5] The power generated will be evacuated via a new 400kV high voltage power line to a substantiation where the power will be integrated into the national electricity grid.[2] The government of Ethiopia is advising the Tanzanian government on the implementation of this project.[6]

In December 2018, The Citizen (Tanzania) newspaper reported that the government of Tanzania had awarded the construction contract for this power project to Arab Contractors Limited of Egypt, at a budgeted cost of US$2.9 billion (TSh6.558 trillion).[7]

In February 2019, the government of Tanzania handed over the construction site to the consortium comprising Arab Contractors and El Sewedy, both of Egypt, who had been selected to build the power station. Allowing six months to mobilize equipment, actual construction is expected to tart in the 3rd quarter of calendar year 2019.[8]
