Everything you need to know about Julius Nyerere Power Station in Tanzania
Hello Displorers, welcome to another informative video presented to you by Displore and thanks for watching. In this video, we shall bring to you everything you need to know about the Julius Nyerere Power Station in Tanzania. The Julius Nyerere Hydropower Station also called Rufiji Hydroelectric Power Station, is a 2,115 megawatts hydroelectric dam under construction in Tanzania expected to produce 5,920GWh of power annually upon completion. The government of Tanzania has been considering establishing this power station since the 1960s and when fully developed, it will be the largest power station in East Africa. The 134 metres arched concrete dam is expected to create a 100km reservoir lake in length, measuring 1,200km2 with 34,000,000,000 cubic metres of water.This east African master piece is not only going to change the face of the region but also the socio-economic life of the people but first, let us look at the origin of this nation changing project.

History
In 1901 German Engineer Stiegler led the first expedition to what is now known as Stiegler's Gorge to consider potential infrastructure. Stiegler, when measuring the gorge, was charged by an elephant and fell into the ravine. It was named after him in his memory. Plans for a dam were developed during British rule of Tanganyika. Alexander Telford conducted the first systematic development surveys of the Rufiji in 1928–1929, with engineer C. Gilman carrying out further studies in 1938–1940. These studies primarily envisioned irrigation infrastructure with a small dam at Stiegler's Gorge to reduce flooding and protect downstream irrigation infrastructure.This changed in the 1950s when the Food and Agriculture Organization, FAO started studying Rufiji River infrastructure. This included a far larger dam wall of around 100metres that aimed to transform the valley to an artificial environment, providing water for agriculture.Plans turned towards hydropower after Tanganyika's independence in 1961.
The Japanese External Trade Organization supported feasibility studies in the 1960s that proposed a 620MW plant. At the same time, Nyerere's government engaged US Authorities and in particular the Bureau of Reclamation and Tennessee Valley Authority. This produced studies planning wider transformation of the Rufiji valley, with the dam enabling irrigation, industrialisation, urban water supply and a large fishery in its reservoir. The US studies also initiated the creation of the Rufiji Basin Development Authority, RUBADA, whose founding mission was to build the dam and facilitate the wider development of the valley. By the 1970s, the Norwegian NORAD development agency had taken on the Stiegler's Gorge Planning, producing detailed feasibility and construction designs.However, these plans were never implemented primarily because of the World Bank's decision to reject project finance. There were also growing environmental concerns around the project, prompting the first Environmental Impact Assessment in Tanzania. These concerns were magnified by the designation of the Selous Game Reserve, in which the gorge sits, as a UNESCO World Heritage site in 1982. The World Bank and other international donors consequently turned to the smaller and less-impactful Kidatu and Pangani Falls Dams in the 1990s.
However, Kikwete's government resurrected plans for the dam in 2006 because of severe power crisis in Tanzania from 2004-2006 that saw widespread load shedding. A series of companies expressed interest in developing the project. Under Kikwete's government, and like other energy sector projects, the dam was supposed to be developed by the private sector. This involved unsolicited bids by private companies for agreements with the government to build the project. The companies would then use these deals, such as power purchase agreements, to raise finance and start construction. However, the main engagement came from Brazil. After a number of exchanges between the two countries happened between 2009–2012, they signed a Memorandum of Understanding with Rubada in 2012 to build the dam. Odebrecht got the contract and undertook feasibility and design studies and commissioned an environmental impact report. However, Tanzanian interest in the dam appeared to stall by 2014, delaying any implementation.
This changed when President Magufuli came to power in 2015. In 2017, he announced that the Stiegler's Gorge Dam would be a flagship development project of his government and would be financed by the government rather than developed by the private sector. A first round of bidding for the construction tenders was held
