Wärtsilä, the Finnish energy and marine technology company, has signed a five-year contract to operate and maintain a 23-megawatt captive power plant at the Boto gold mine in eastern Senegal.
The agreement strengthens the company’s presence in Africa’s mining and energy markets, where demand for steady electricity is growing alongside new mineral projects.
The deal reflects a wider trend in West Africa, where gold production is climbing and energy security has become essential for industrial expansion. Reliable power is often the difference between smooth operations and costly disruptions in remote mining regions.
Keeping the lights on in remote Senegal
The Boto mine sits in the Kédougou region, close to Senegal’s borders with Mali and Guinea. Electricity in such areas cannot rely on the national grid, making self-contained power systems a necessity.
Wärtsilä’s plant will combine six Wärtsilä 32 engines with four high-speed diesel generators to supply round-the-clock electricity. The setup aims to deliver stability in a region where outages can derail both mining output and local development goals.
The project also aligns with Senegal’s “Plan Sénégal Émergent,” the government’s long-term blueprint for industrial growth and energy independence.
Gold production depends on efficient energy
Under Senegalese energy framework, mining operators must generate their own electricity. That makes fuel efficiency, cost savings, and minimal downtime central to profitability. Wärtsilä’s tailored plan for Boto integrates digital monitoring and artificial intelligence to detect potential faults, optimize fuel use, and reduce downtime.
The Morocco-based Managem Group, is running its first self-owned power plant through this partnership. For the company, reliable power means not only steady gold output but also the ability to plan for renewable integration in the future.
“Supporting Managem Group on their first self-owned power plant reflects our commitment to Africa’s mining sector,” said Marc Thiriet, Wärtsilä’s energy business director for Africa. “Our flexible engine technology can address immediate needs while allowing solar energy to be added when the time is right.”
Beyond mining: jobs and local impact
The power plant is also expected to generate local employment in Kédougou, providing technical roles and maintenance jobs. That fits into Senegal’s national goals of tying mining expansion more closely to economic development.
“This partnership is a major step forward for our operations in Senegal,” said Driss Mounji, chief international operations officer at Managem Group. “Wärtsilä’s tailored approach and digital tools give us the confidence to produce gold more reliably, while preparing the ground for future renewable energy.”
Senegal’s mining and energy crossroads
Senegal is increasingly positioning itself as a regional hub for sustainable industrial growth. Gold mining has brought foreign investment and export revenues, while the government is pushing for greater energy independence through a mix of fossil and renewable projects.
Wärtsilä’s latest contract highlights how mining, energy security, and renewable ambitions are becoming intertwined across Africa’s resource economies. For Senegal, it signals another step toward balancing industrial growth with long-term sustainability.
