Project General Description

The Malagarasi Hydropower project involves a Construction of a 44.8MW hydropower plant in Western Tanzania that will provide reliable renewable energy to households, schools, clinics and small and medium-sized enterprises in the Kigoma Region. The hydropower plant utilizing Igamba falls stage III with associated facilities, a switch yard at Malagarasi. The project is one of the flagship physical infrastructure investments in the Government of the Tanzania’s Development Vision 2025 and Tanzania’s current Five-Year Development Plan, and that it will increase the share of renewable energy in Tanzania’s energy mix. It has several components: a run-of-the-river hydropower plant facility; a 54- km, 132 kV transmission line that will connect to Tanzania’s national grid; a distribution network expansion operation that includes rural electrification and last-mile connections; project management and contract administration support; and compensation and resettlement of affected persons. The project’s overall project cost is estimated at $144.14 million.

Project Objectives

The ultimate development objective (DO) of Malagarasi HPP is to improve power supply in western Tanzania in addition to increasing the power generation capacity in order to foster socioeconomic transformation.


The project is expected to create about 700 jobs during construction, cut the region’s electricity generation costs to approximately $0.04/kWh from the current $0.33/kWh, and also reduce reliance on greenhouse gas-emitting fossil fuels. The hydropower plant’s expected average annual output of 181 GWh will meet the electricity needs of as many as 133,649 Kigoma households, bringing the region’s electrification rate more closely in line with the rest of the country.
