Ilala substation, targeted site of the Project for Reinforcement of Power Distribution in Dar es Salaam

The increasing power demand in Dar es Salaam goes beyond of the supply capacity of existing transmission and distribution system because of the decrepitude transmission and distribution equipment and shortage of equipment maintenance. The equipment is operated in a situation whereby its condition far exceeds the supply capacity. The huge amount of power loss has been a matter of great concern to the management of Tanzania Electric Supply Company (TANESCO).

The project consists of the following components:

1. The construction of three new substations (Muhimbili, Mwananyamala and Jangwani Beach) and the construction of approximately 17.2 km 33kV distribution line between the existing substations and the three new substations
2. The reinforcement of Ilala and Msasani substations and the reinforcement of the existing 7.5km 132kV transmission line between Ubungo substation and Ilala substation.

By implementing these components, the project will greatly contribute to improving stability of the power supply in Dar es Salaam city, which will lead to further development of economic activities and improvement of social services such as schools and hospitals. Within three years after the completion of the project, it is expected that 47 thousand households will be electrified, the power loss rate improved from 15.65% to 11.95% in Dar es Salaam region. According to the grant agreement the detailed design survey mainly targeting the above sites will be implemented.
