Despite making a negligible contribution to global warming, Sub-Saharan Africa is suffering its effects more than anywhere else in the world. Changing rain patterns, increasing temperatures, more frequent storms and natural disasters are challenging already-vulnerable communities across the continent.

The urgent need to mitigate climate change, and falling technology costs, are driving many African countries to harness their rich renewable energy resources –  including solar, hydro, wind and geothermal – but significant infrastructure investment is needed to accelerate the growth of these sectors. This is a huge opportunity for the private sector.

At Maris we are developing scalable business models that generate compelling returns while absorbing the high-upfront costs of renewable energy. With investments in the commercial and industrial solar sector, hydro power, and electric transportation, our goal is to support environmentally sustainable development and accelerate Africa’s  transition to a low-carbon economy.


Equator Energy

70% ownership

Equator Energy is the largest industrial and commercial solar power provider in East Africa, servicing clients in five countries. We provide fully integrated renewable energy systems which pay for themselves, requiring no investment by the client. Our solution range from simple grid-tied systems, to solar-diesel hybrid systems, to fully autonomous off-grid systems. Our plants’ peak-power output and total energy production are carefully matched to the clients’ needs.


Meta Electric

100% ownership

Meta Electric is a business-to-business sales and leasing company focused on electric commercial vehicles. Meta Electric is an industry pioneer and one of the first Kenyan companies to go to market with an electric vehicle (EV). This represents an exciting opportunity to seed the Kenyan market with EVs at an early stage and build the required capacity to support the e-mobility revolution in Africa.  The lease program allows business owners to operate fleets of EVs without incurring the high buy-in costs.


Suma Hydro

30% ownership

The Suma  3,8 MW Hydro & Rural Electrification Project, currently under construction, is a joint venture between Rift Valley Energy, TATEPA and AgDevCo. It will be a run-of-river hydro power plant enabling the neighbouring tea industry to reduce reliance on costly and polluting back-up diesel generators. The main off-taker will be Tanzania’s National Utility with an opportunity to directly connect clusters of local rural housing and small businesses to the national grid main line.
