1.Project Honors:

Africa's largest hydropower project in terms of installed capacity

 

2.Project Overview:

The Julius Nyerere Hydropower Station is located on the Rufiji River in southeastern Tanzania, approximately350kilometers from Dar es Salaam, Tanzania's largest city and capital. The main tasks of this project are power generation and irrigation. The power station has a total of9generating units, with a total installed capacity of2115MWand an annual power generation of6307GW·h. The maximum dam height of this project is approximately131mand the total water storage capacity exceeds300cubic meters. After completion, the power station's installed capacity will account for60%of Tanzania's total installed capacity, making it the country's main power generation base.

 

The main construction content of the project includes a main dam and its ancillary structures. The main project involves approximately500cubic meters of earth and stone open-pit excavation, and59.24cubic meters of stone excavation from tunnels and wells. The project also includes237.2cubic meters of concrete, and5.7tons of steel bars, and29.5cubic meters of curtain grouting. This project is the largest hydropower project in Africa to date, surpassing Egypt's Aswan High Dam(2100MW)、Mozambique's Cahora Bassa Dam(2075MW)and Angola's Lauca Dam(2069MW)to become the dam with the largest installed capacity in Africa.

 

3.Technical Challenges:

Complex terrain and geological conditions; the project is located in a Tanzanian national park, with high environmental requirements near the dam area; relatively low local building material production capacity and limited transportation conditions; weak industrial base and relatively scarce materials; very high temperatures during the dry season and large temperature variations throughout the year.

 

4.Key Ancillary Projects:

131meter-high roller compacted concrete dam,9water diversion tunnels, surge shafts, and surge inclined shafts

 

5.Value and Significance:

The Julius Nyerere Hydropower Station is a benchmark project for Tanzania's realization of its new industrialization dream. During the construction of this project,1.2jobs were created, comprehensively driving the development of the local building materials, commerce, transportation, and mining industries, and promoting economic development and improvement of people's livelihood in Tanzania.

 

After the completion of the project, the country's installed power generation capacity will increase by1.4times, and the power supply situation will be greatly improved, which will help the local socio-economic development. While alleviating the power shortage, it will also help Zambia better cope with climate change, and water resources can also be scientifically managed.
