During the JNHPP's filling ceremony, which will be attended by Tanzanian President Samia Hassan along with officials and figures of the Tanzanian society, the diversion tunnel's gate will be closed to start the process of  filling the dam reservoir, a statement by the foreign ministry said on Wednesday.

The Egyptian delegation includes Egypt's Housing Minister Assem El-Gazzar in addition to Shoukry.

Construction of the $3 billion JNHPP was concluded in October 2022. Began in 2019, JNHPP was constructed  through a joint venture of two Egyptian companies – the Arab Contractors Company and El-Sewedy Electric – to double Tanzania's current energy production, control floods and improve agriculture.

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 manmade reservoir, which has an area of about 158,000 square kilometres.

It is expected to have installed capacity of 2,115 megawatts and to produce 5,920 GWh of power annually, according to a previous statement by the housing ministry.

The JNHPP is considered one of the most important developmental projects in the African continent, said the Egyptian Foreign Ministry Spokesperson Ahmed Abu Zeid. He added that it reflects the capabilities of Egyptian companies to execute mega infrastructure projects in different countries.

"It [JNHPP] serves as a model for regional cooperation with African brother countries to support developmental efforts and promote their populations’ interests," the statement quoted Abu Zeid as saying. 

Ahmed El-Sewedy, the CEO managing director of El-Sewedy Electric, stated earlier that the dam aims to strengthen the Tanzanian economy by generating power to supply various industries, creating jobs and furthering other development goals.

The dam is expected to solve the country's electricity shortages problem by securing clean power to more than 60 million Tanzanians, he said.

More than 2,500 Egyptian and Tanzanian engineers and workers participated in the construction of the dam, putting in a total of 22 million working hours, El-Gazzar  previously said.
