TANESCO has constructed a temporary overhead power transmission line to ease electricity supply disruptions affecting parts of Mbagala, Kigamboni, Mkuranga and Kibiti, following a fault in a major underground transmission cable at Gongolamboto.
The intervention is intended to improve electricity supply to households, businesses and other customers in the affected areas while engineers work to repair the damaged 132-kilovolt (132kV) underground transmission line.
The temporary line crosses the Standard Gauge Railway (SGR) infrastructure, providing an alternative route for transmitting electricity and bypassing the damaged section of the underground system.
Tanzania Electric Supply Company (Tanesco) Managing Director Lazaro Twange said on Saturday, November 7, 2026, that the alternative connection was developed as an emergency measure to reduce the impact of the disruption on customers.
During an inspection of the repair works, he commended the utility's technical teams for responding quickly and developing an alternative transmission arrangement.
"We are here to inspect progress and see the measures being taken by our technical teams. We are encouraged that they have managed to construct an alternative overhead transmission line crossing the SGR area to ensure electricity continues reaching our customers while repairs to the underground line are under way," he said.
Mr Twange assured customers that Tanesco was continuing with technical interventions to restore normal electricity services, adding that reliable supply and customer satisfaction remained priorities.
The development comes after a fault emerged on November 3, 2026, along the underground 132kV transmission line connecting Gongolamboto substation to Mbagala and Dege substations in Kigamboni.
The disruption affected parts of Mbagala, Kigamboni, Mkuranga and Kibiti because the existing alternative transmission route had limited capacity and could not accommodate the combined electricity demand in the affected areas.
This meant that the available backup infrastructure could not fully compensate for the damaged transmission line, prolonging supply challenges for some customers.
Tanesco's technical teams are now working to connect and complete the temporary overhead system, with the process requiring strict adherence to safety procedures before it is ready for effective operation.
The utility said repair work on the damaged underground infrastructure was continuing, with the temporary arrangement expected to ease pressure on electricity supply as efforts to restore the normal transmission system proceed.
For residents and businesses in the affected areas, the restoration of reliable electricity is important for maintaining daily activities, commercial operations and access to essential services.
Tanesco said it would continue implementing technical measures to restore normal supply and strengthen the reliability of electricity services in the affected areas.
