Africa is ready to provide enough energy to achieve the most ambitious of goals, and it can do it while maintaining all environmental targets.
We believe careful planning of power systems towards more sustainable and diversified energy supply portfolios can save billions and rapidly reduce CO2 emissions. We create value through our extensive power system knowledge and experience from integrating different generating assets.

With more than 650 employees and service hubs located in Kenya, South Africa, Nigeria and Senegal, Wärtsilä is proud to have contributed to many industry firsts. These include Africa’s largest gas engine power plant on the Kribi coast of Cameroon with 216MW capacity, as well as Africa’s highest installation, the 175 MW power plant in Sasolburg, South Africa, sitting at 1,700 meters above sea level.
Another first, the KivuWatt power plant in Rwanda, is the first ever power plant to use the naturally occurring methane from lake Kivu to generate electricity and reduce the environmental risks associated with such high concentrations of gas. Today’s power output is 25 MW but future planned expansions to this project will increase capacity by an additional 75 MW.
Since deciding in 2009 that its three new power plants would operate with Wärtsilä gas engines rather than gas turbines, the conventional choice at that time in Nigeria, Paras Energy has continued to benefit from that decision.Read more

Our GEMS Digital Energy Platform together with energy storage solutions were the key players in helping the Fekola gold mine in Mali to reduce their dependency on expensive fuel, lower their carbon emissions and optimise their mining operations.Read more
The Central Electricity Board (CEB) of Mauritius improved the performance as well as reduced the operating costs of their power plant by having a turbocharger retrofit.Read more
The Essakane gold mine in Burkina Faso receives its needed power from Africa’s largest engine-solar PV hybrid power plant delivered by Wärtsilä. Benefits for the mine include reduced fuel costs and a smaller carbon footprint. The capability to control and optimise the usage of the solar PV power and engines enables the gold mine to reduce its fuel consumption by an estimated 6 million litres per year and its annual CO2 emissions by 18,500 tons.Read more
With 450 MW of installed capacity in Senegal, Wärtsilä is the country’s leading provider of power generation equipment. The Matelec company placed an order for the delivery of an energy efficient 130 MW Flexicycle™ power plant. This investment will enable Senegal to achieve its goal of reducing consumer electricity pricing.Read more
The Grande Côte Mineral Sands Project aims to extract valuable zircon and titanium dioxide from sandy deposits along the Senegalese coast from 2014 for at least the next 20 years.Read more
"Our old generating equipment was replaced with more efficient units. New power plant technology is used to meet increased demand for electricity. Gas-engine technology allows us to reduce our carbon footprint by more than 40%."Read more
This power plant utilises naturally occurring methane gas from Lake Kivu to generate electricity via Wärtsilä 34SG engines. Total output will be 25 MW. By reducing gas levels in the lake while, at the same time, providing additional power generating capacity, both environmental and economic targets can be met. This is the first time that Lake Kivu’s methane gas will be used to fuel a power plant of this size.Read more
Technology group Wärtsilä has signed a ten-year Guaranteed Asset Performance (GAP) agreement with US utility Omaha Public Power District (OPPD). The agreement covers the 150 MW Standing Bear Lake Station located in Omaha, Nebraska and is set to commence commercial service in 2024. Upon activation, the plant will provide dispatchable balancing power as part of the utility's Power with Purpose project, an initiative designed to add 400 to 600 MW of utility-scale solar generation and 600 MW of balancing natural gas generation. The order was booked by Wärtsilä in Q3, 2023.
The aim of the utility is to reach net-zero carbon emissions by 2050. By ensuring operational reliability for the plant, the agreement supports these efforts with fast-starting balancing power to rapidly compensate for fluctuations in the supply of renewables. The supply to the grid is therefore assured regardless of the conditions.
The plant operates with nine Wärtsilä 18V50DF dual-fuel engines which can use natural gas and light fuel oil as needed. The engines can be converted to carbon neutral fuels as they become available to further enhance decarbonisation.
“Wärtsilä shares the same energy-sector decarbonisation goals as OPPD, and we look forward to continuing our close cooperation with them. The performance guarantees included in our GAP agreements deliver the reliability of supply needed for the system integration of renewable energy. Furthermore, they represent a central pillar in our Lifecycle Support approach to optimising operational performance,” commented Jon Rodriguez, Energy Business Director, Engine Power Plants at Wärtsilä.
During the agreement, Wärtsilä will provide site services and also support through connection to the Wärtsilä Expertise Centre in Houston, Texas, enabling remote support, maintenance planning, and predictive maintenance intelligence.
