Glasgow-based Aggreko has won a contract worth about £31m to supply power to the Côte d'Ivoire.
Aggreko will supply temporary power fuelled by natural gas to support the country's national grid for the next two years.
The company said it had more than a decade of experience in Africa, supplying in excess of 1,000 MW of power across 17 countries.
It also rents out generators for major events such as the Winter Olympics.
The company employs more than 3,500 people worldwide including about 200 at its Glasgow headquarters.
In the latest stock market reshuffle, Aggreko joined the FTSE 100.
