December 20183 min read

Nairobi, 2 December 2018 — responsAbility Renewable Energy Holding (rAREH), the responsAbility-managed Nairobi-based energy company focusing on Sub-Saharan Africa, is starting a new chapter in its company history: Rwaza I, a 2.7 MW run-of-the-river hydropower plant located on Rwanda’s Mukungwa river, is the first rAREH project to become operational. 

The Republic of Rwanda ranks among the lowest in the region in terms of electricity consumption per capita. Located on Rwanda’s Mukungwa river in the Rwaza-Muko area, the 2.7 MW hydropower plant Rwaza I has now started feeding electricity into the Rwandan grid. The small-scale power plant uses the environmentally-friendly run-of-the-river technology. The project company, Rwaza Hydropower Limited, is financed on an all-equity basis, with rAREH and DI Frontier Market Energy & Carbon Fund each providing 50% of the funding.

Following a 2-year development phase, Rwaza I was officially handed over by the contractor on 30 November 2018. In answer to a request by the Rwandan government to compensate a shortfall in available power generation capacity in the country, the plant first started feeding electricity into the Rwandan grid upon the completion of the transmission line in September 2018. 

rAREH Managing Director Joseph Nganga said: “The start of operation at Rwaza opens a new chapter in our company history by taking rAREH from being a financer and developer of renewable power plants to becoming an energy company active across all stages of development including the owning of operating of power plants. Our 17-strong team is currently working on 15 projects representing a total capacity of 286 MW and we look forward to expanding our portfolio of operational assets in the years to come.”
