The proposed Malagarasi Hydropower Plant Stage III was recommended after Malagarasi Stage II was dropped due to environmental concerns. The power plant has been designed to yield a maximum of 44.8MW using maximum water flow of 171m3/s and deliver 186.8 GWh with a plant factor of 0.48. The plant will have 3 generators rated 15.75MW each utilizing a head of 30.5m and unit water flow of 57m3/s.
The transmission line will utilize a 20m wide corridor from Malagarasi switch yard to Mazungwe and 26m wide corridor from Mazungwe to Kidahwe respectively. Two types of towers are being considered mono tubular towers or self-supported lattice steel towers. Both will have concrete foundations.
