The Project includes laying an approximately 40 km long, 100MW capacity submarine electric transmission cable (including telecom fiber optic shield wire) from the mainland to Unguja Island, along the path of the existing submarine cable that is reaching its limits in both capacity and lifespan. To support the additional transmission capacity, the activity also includes the reinforcement of substations at either end of the cable, as well as the corresponding installation of roughly 20 km of supplementary transmission capacity along existing lines. This activity is expected to provide a reliable and non-polluting power supply to Unguja Island, the largest island in the Zanzibar archipelago with a population of approximately 700,000, which is entirely dependent on power supply from the mainland. This will allow the island to continue to develop its potential as a high-value tourist destination. The increased supply of electricity will also improve the productivity and quality of life for the islandâ€™s population.
Malagarasi Hydropower & Kigoma Distribution.
The Project includes the construction of a small, 8 MW run-of-river hydropower plant on the Malagarasi River at Igamba Falls, and the extension of a mini-grid system in the Kigoma region, which suffers from an inadequate and unreliable power supply. This lack of access to reliable power has been one of the major constraints to investment in commercial and industrial operations in the region. This activity seeks to displace costly, inefficient, and polluting diesel power generation with affordable, reliable, and clean renewable small-scale hydropower. The expanded distribution system will also facilitate the electrification of rural villages and towns. In addition, this activity will include the assessment and design of a public-private partnership for the independent operation of the completed mini-grid system. Such partnership will provide an opportunity to increase the participation of the private sector in the national electricity system.
Distribution Systems Rehabilitation & Extension.
The Project includes the rehabilitation of existing distribution infrastructure and a number of small distribution line extensions to un-served areas in six regions (Mwanza, Tanga, Morogoro, Iringa, Dodoma, and Mbeya) that were identified by the GoT as priority areas for investment. By complementing similar projects to be funded by the World Bank in the regions of Dar es Salaam, Kilimanjaro, and Arusha, this activity will address the growing demand and the corresponding strain on the network to deliver reliable and quality power to industrial and commercial users, as well as to households, in these regions.
