By GlobalDataThe O&M contract covers operation and maintenance of the engines, AI-powered anomaly detection, and remote operational support designed to ensure efficiency, optimised fuel consumption, and reduced downtime.
In compliance with Senegalese regulations, mining companies are required to operate their own power generation facilities in such areas, necessitating reliable energy solutions for industrial growth.
Managem Group chief international operations officer Driss Mounji said: “This partnership is a major step forward for our operations in Senegal. Wärtsilä’s tailored approach and advanced digital solutions provide us with the confidence to produce gold more reliably and efficiently, while also laying the foundation for future renewable integration.”
Wärtsilä Energy Africa energy business director Marc Thiriet said: “Supporting Managem Group on their first self-owned power plant reflects our commitment to delivering resilient, cost-efficient energy to Africa’s mining sector.
“This project demonstrates Wärtsilä’s deep understanding of Senegal’s energy landscape and our ability to operate in alignment with the country’s industrial growth and energy independence goals. Wärtsilä’s flexible engine technology allows for future integration of solar energy, supporting Senegal’s broader push toward renewable energy and sustainable industrialisation.”
The project also aims to generate employment in the Kédougou region by engaging local personnel.
