Project General Description

The North West Grid (NWG) 400 kV Nyakanazi - Kigoma Transmission Line Project aims to provide affordable and reliable main grid access to already electrified but isolated grids and, therefore, replace the expensive dieselbased power generating plants in Kigoma and Kasulu towns. It will evacuate power from the proposed renewable generation plants in Kigoma Region including the multinational Rusumo hydropower plant (HPP). The Project comprises: (i) Construction of a 280 km power line running from Nyakanazi to Kigoma in the northwestern part of Tanzania; (ii) Extension of Nyakanazi substation & construction of a new substation at Kidahwe near Kigoma town; (iii) Integration of existing Kigoma &Kasulu 33 kV distribution networks to the main grid including supply of last-mile connection materials to serve at-least 10,000 potential consumers in Kigoma Region; (iv) Consultancy Services; (v) Audit Services and (vi) Compensation and/or resettlement of project affected persons. The Project will form part of the proposed 1,080 km NWG stretching from Nyakanazi (via Kigoma, Mpanda, Sumbawanga and Tunduma) to Mbeya. Its overall cost is estimated at USD 186.12 million.

Project Objectives

The ultimate development objectives of the Project comprise: (i) improve power supply through provision of main grid reliable and affordable electricity (ii) lower energy production costs by decommissioning the expensive diesel power plants in Kigoma & Kasulu (iii) enhance job creation (iv) reduce GHG emissions and (v) provide power evacuation facilities for the Rusumo HPP and other renewables.


The Project will provide reliable main-grid electricity to existing connections in Kigoma region including households, social amenities, SMEs and large electricity consumers in addition to targeting a connectivity rate of at-least 20% (in 2023) with associated increase for female-headed homes. In order to achieve 20% connectivity, at-least 18,368 new connections (taking into consideration population increase) are required of which the Project will provide 10,000.
