The Government of Tanzania has invested Sh514 billion in the construction of a 400kV electricity transmission line from Chalinze to Zuzu in Dodoma, a major infrastructure project aimed at strengthening the national power supply system and supporting economic growth across the country.
The project, implemented by the Tanzania Electric Supply Company Limited (TANESCO), has reached 82.5 percent completion and is expected to be completed by August 18, 2026.
TANESCO Managing Director, Lazaro Twange, said the project is a key national investment designed to improve the transmission of electricity generated from the Julius Nyerere Hydroelectric Power Project to major demand centres, including Dodoma and surrounding regions.
He made the remarks on May 20, 2026, during an inspection visit of the project in Morogoro and Dodoma regions, where he reviewed progress and urged faster implementation of remaining works.
Twange said the transmission line will play an important role in improving the reliability and stability of electricity supply, especially as demand continues to grow due to population increase, industrial expansion, and rising investment activities.
He noted that the project is being implemented alongside the expansion of substations at Chalinze and Zuzu, which are essential in regulating and distributing electricity safely and efficiently once it is transmitted through the national grid.
“The Government has made a huge investment of Sh514 billion to ensure this project is completed successfully. It is a strategic project that will improve electricity supply and support economic activities across the country,” said Twange.
He added that once completed, the project will improve access to reliable electricity for households, industries, and public services, while also supporting new investment opportunities in different sectors.
Twange also directed the contractor to increase speed by deploying more technical staff and equipment to ensure the project is completed within the agreed timeline.
“We want this project completed on time. We have agreed that more experts and equipment must be added so that all remaining works are finished as scheduled,” he said.
Project Manager, Engineer Newtone Lingstone, said the 345-kilometre transmission line from Chalinze to Dodoma is fully funded by the Government of Tanzania and is progressing steadily.
He said construction works are moving well, including installation of transmission towers, stringing of high-voltage cables, and upgrading of substations at Chalinze and Zuzu.
According to him, once completed, the project will significantly improve electricity reliability not only in Dodoma but also in other connected regions across the national grid.
The project is expected to strengthen Tanzania’s electricity infrastructure and support the country’s long-term development goals by ensuring stable and sufficient power supply for both social and economic activities.
