Wärtsilä Energy in Africa

Taking Africa to its Energy Future

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.

On this page, you may find our best materials and proceedings in energising and decarbonising the continent of Africa.

Wärtsilä’s Industry Firsts in Africa

With more than 650 employees and service hubs located in Kenya, South Africa, 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. 

Our references from across the continent

  • Paras Energy, Nigeria

    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.

  • Geita Gold Mine, Tanzania

    Reliable power generation in a remote off-grid location in Tanzania.

  • B2Gold Fekola Mine, Mali

    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.

  • Pointe Monnier, Mauritius

    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.

  • Essakane Solar SAS, Burkina Faso

    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.

  • Kaloum 5, Republic of Guinea

    Power plant overhaul boosts availability and grid stability.

  • Malicounda, Senegal

    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.

  • Grande Côte, Senegal

    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.

  • Sasolburg, South Africa

    "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%."

  • Lake Kivu, Rwanda

    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.

Wärtsilä demonstrates commitment to South Africa's B-BBEE integration programme with Level 4 certification

Feb 5, 2021, 09:00 AM by Wärtsilä Corporation

Wärtsilä has achieved Level 4 score as a contributor to South Africa’s Broad-Based Black Economic Empowerment (B-BBEE) integration programme. This recognition was given as a result of Wärtsilä’s company restructuring in 2020, whereby its South African operations were separated from its activities in other southern African countries. The ownership structure was certified by a SANAS B-BBEE verification agency in December 2020.Among the major measures taken, Wärtsilä has established an Engineering Studies Ownership Trust as a black South African shareholder in Wärtsilä South Africa, and actively supports education in South Africa in line with the company’s Corporate Social Responsibility values.

B-BBEE is a programme actively promoted by the South African government. It provides a legislative framework for advancing the economic transformation of South Africa’s economy and enhancing the participation of black citizens in it.  Government tenders in South Africa, such as the Risk Mitigation Independent Power Procurement Program (RMIPPP), require level 4 certification and a minimum black South African shareholding of 25 percent. As part of the B-BBEE Act and its Codes of Good Practice, plus to fulfil the requirements for RMIPPP compliance, Wärtsilä has also increased its use of South African suppliers and sub-contractors, and has increased its locally-hired workforce.  

“The level 4 certification enables us to remain an active and committed contributor to the future development of the South African economy. Our partnerships and cooperation with the likes of Nelson Mandela University that date back to 2014, show that as a company, we are deeply invested in the development of our people and communities,” says Mr Tord Johnsson, General Manager Strategy and Growth Projects, Africa & Europe at Wärtsilä Energy.

”We see the establishment of the Engineering Studies Ownership Trust as an opportunity to further stimulate and encourage engineering studies for the benefit of all involved, including our industry and Wärtsilä South Africa as a company. We have recruited additional personal and competences and will continue to do so as our business grows,” commented Feroza Cassim, Managing Director of Wärtsilä South Africa.  

Wärtsilä has been operating in South Africa since 1994 and has an extensive and successful track record throughout Africa, having supplied power plants to almost every country of the continent representing a total capacity of over 7000 MWe. One of the biggest power plants in Africa with Wärtsilä’s technology is the 175 MWe power plant in Sasolburg, delivered in 2012 to South Africa.  More than 25 percent of the national electricity supply in more than 25 of the continent’s countries is produced by Wärtsilä technologies. Wärtsilä has an office in Johannesburg, and a service office and workshop in Cape Town in South Africa. Wärtsilä currently employs 40 people in South Africa.
