Tanzania has taken a monumental step in its energy sector by launching the 400kV Chalinze-Dodoma power transmission line and expanding substations in Chalinze (Pwani Region) and Zuzu (Dodoma Region).
The project, inaugurated by Deputy Prime Minister and Minister of Energy, Hon. Dr. Doto Biteko, marks a transformative moment in the country’s quest for reliable energy distribution and regional power trade.
“This project demonstrates the government's commitment to providing sustainable and reliable electricity for every Tanzanian. It reflects the leadership of President Samia Suluhu Hassan, who has prioritized energy projects to drive economic growth and social transformation,” said Dr. Biteko during the launch ceremony.
The initiative is a key enabler for transmitting electricity generated by the Julius Nyerere Hydropower Project (JNHPP) to various regions across Tanzania, including the Northern, Lake, Southern Highlands, Central, and Western Zones.
It will also support industrial and mining operations while enhancing electricity trade with neighboring countries in Eastern and Southern Africa.
Dr. Biteko emphasized the significance of the development, noting that Tanzania now leads Africa in electricity distribution, as recognized by the World Bank.
“Our installed electricity capacity has reached 3,169.26 MW, far exceeding the peak demand of 1,888.72 MW. This milestone underscores our country’s rapid economic growth and increasing energy needs,” he added.
The JNHPP, a flagship project with a generation capacity of 2,115 MW, is now 99.6% complete.
“So far, 1,175 MW from this project has been integrated into the national grid, solidifying Tanzania’s position as a regional leader in power generation,” said Dr. Biteko.
He called for stringent action against individuals sabotaging energy infrastructure, describing such acts as a threat to national development.
Fully financed by the Tanzanian government at a cost of TZS 513 billion, the transmission project includes constructing a 345-kilometer line and expanding substations to support the national grid.
The contractor, TBEA from China, has already received TZS 107.93 billion as part of the project’s funding. Completion is expected by September 2026.
“This project will enable us to transmit the 2,115 MW from JNHPP to all regions of Tanzania, ensuring improved electricity access while strengthening regional power trade through interconnections with Eastern and Southern Africa,” said TANESCO Managing Director, Engineer Gissima Nyamo-Hanga.
Beyond energy transmission, Dr. Biteko underscored the government's efforts to promote clean cooking energy solutions.
“The government has subsidized 400,000 gas cylinders, offering them at half the market price to encourage Tanzanians to shift from charcoal and firewood to cleaner alternatives like gas and electricity. We urge all stakeholders to make efficient electric stoves affordable and accessible, especially to rural households,” he said.
Other dignitaries applauded the initiative. Minister for Home Affairs, Hon. Innocent Bashungwa, praised the project as a testament to President Samia’s vision of providing sustainable energy.
“The government is investing heavily in energy infrastructure, and my ministry will ensure this infrastructure is protected from vandalism,” he said.
Deputy Minister for Energy, Hon. Judith Kapinga, hailed the launch as a landmark moment for Tanzania's energy ambitions.
“This project is critical not only for our domestic needs but also for positioning Tanzania as a major player in regional power integration,” she said.
Wendy Hughes, the World Bank’s Regional Director for Eastern and Southern Africa, commended Tanzania’s progress.
“Reliable electricity is essential for economic and social development. Tanzania’s efforts to strengthen its power grid set an example for Africa,” she noted, pledging continued support to help the country meet its goals, including providing electricity to 300 million people across the continent by 2030.
The Chalinze-Dodoma power transmission project is a testament to Tanzania’s vision of a modernized energy sector. It promises to meet the growing domestic energy demands and solidify the country’s role as a regional energy leader, driving industrial growth and fostering cross-border electricity trade.
