The contract has an option to extend by a further two years.
Located in the Vridi area of Abidjan, the power plant provides critical power to Ivory Coast and surrounding countries interconnected to the Ivory Coast grid.
CI-Energies director general Amidou Traore said: "We are pleased to be extending the Aggreko project which forms an important part of our program of strengthening the energy infrastructure across the country.
"The 200 MW supplied from the Aggreko plant is an important component of our energy generation mix and helps us maintain supply to our customers while we develop our long-term infrastructure programmes."
Aggreko North and West Africa managing director Christophe Jacquin said: "Our project in Ivory Coast is a great example of the value Aggreko brings to its utility customers in Africa.
"Our solutions address shortages in power generation capacity, giving our customers the ability to maintain supply while they work to improve their systems."
