Tanzania Electric Supply Company Limited (TANESCO) has completed the first phase of conductor stringing works on the 400kV Chalinze–Dodoma Transmission Line Project, bringing the strategic power infrastructure investment closer to completion and strengthening prospects for a more reliable national electricity supply.
The utility said the works, carried out in Mkambarani, Morogoro Region, were completed on schedule, allowing electricity services to be restored in all areas affected by the temporary outages required for the operation.
Speaking to journalists on August 5, TANESCO Acting Director of Communications and Customer Service, Ms Irene Gowelle, said the successful completion of the exercise marked an important step in the final stages of implementing the transmission project, which is expected to play a critical role in reinforcing Tanzania’s National Grid.
“The work was completed successfully and within the planned timeframe. We appreciate the patience and cooperation shown by our customers and stakeholders throughout the exercise,” she said.
She noted that once completed, the 400kV transmission line will improve the capacity and stability of the National Grid, enabling more efficient transmission of electricity from generation centres to demand areas across the country.
The project is expected to support growing electricity demand from households, businesses and industries while enhancing grid reliability as Tanzania expands its power generation capacity.
Ms Gowelle also announced that the second phase of conductor stringing works will be undertaken in the Kikombo and Mkonze areas of Dodoma between August 11 and 14. She said TANESCO would issue advance notices on planned power interruptions to enable customers to prepare accordingly.
“We will continue providing timely information to customers as the project progresses to ensure minimal disruption to economic and social activities,” she said.
Chalinze–Dodoma Project Manager, Eng Newton Mwakifwamba, said the first phase involved stringing conductors across major infrastructure, including the Standard Gauge Railway (SGR), the Morogoro I and Morogoro II 220kV transmission lines, as well as an existing 132kV transmission line.
He said all activities were completed safely and efficiently, despite the technical complexity of working around critical transport and energy infrastructure.
“The importance of this project lies in its ability to increase the capacity of the existing transmission network. The 400kV Chalinze–Dodoma line will significantly strengthen the National Grid and improve the reliability of electricity supply nationwide,” he said.
According to TANESCO, the project has reached 94 percent completion and is scheduled for commissioning on August 21, 2026.
The transmission line forms part of broader efforts to modernise Tanzania’s electricity infrastructure and accommodate rising demand driven by industrialisation, urbanisation and ongoing investments in power generation.
