Described as “an example of cooperation” between African countries in development projects, especially in the water sector, the JNHPP will be the largest dam in Tanzania when complete.

The project will more than double Tanzania's current energy production, control floods and improve agriculture.

Ahram Online sheds light on the project's main aspects:

  • The JNHPP is located in the Morogoro area on the Rufiji River in Tanzania.
  • The dam will control the Rufiji River’s deadly floods and introduce efficient commercial agricultural schemes.
  • It will also save up to 400 hectares of trees annually and secure a permanent water supply serving nearly 60 million Tanzanians.
  • The project dates back to 2017 when Tanzania announced bids for the project; an Egyptian consortium was selected in 2018.
  • Construction of the $2.9 billion JNHPP began in 2019 through a joint venture of two Egyptian companies: the Arab Contractors Company and Elsewedy Electric.
  • The JNHPP’s total length is 1,025 metres at crest level and 130 metres at dam level, with a storage capacity of about 34 billion cubic metres in its reservoir.
  • The project comprises a main dam and four other saddle dams forming its reservoir.
  • It is expected to have installed capacity of 2,115 megawatts and to produce 5,920 GWh of power annually.
  • Out of total nine turbines, the first one was installed in August 2021
  • 12,000 labourers – the majority of which are Tanzanians – are taking part in the project, with 1,700 pieces of construction equipment.
  • President El-Sisi said the project is a symbol of friendship between Egypt and Tanzania and also a leading model for constructive cooperation.
  • It is also an example of Egypt’s support Nile Basin countries’ rights to make the best use of their water resources, El-Sisi said.
  • The JNHPP is scheduled to be completed by the end of 2022.
