The 150MW biomass power plant, upon completion, will be the largest biomass facility in the country, the company said.
Under the contract, Areva will provide engineering, procurement and construction services for the Campo Grande plant.
The power plant will feature three 50MW modules and will be fuelled with woody biomass.
Areva Renewables CEO Louis-François Durret said: "Awarded as part of the first biomass plant project undertaken in Brazil in recent years, this success illustrates BOLT Energias’ recognition of AREVA’s knowledge in construction and technological expertise.
"This contract will mark the first step of a successful collaboration with our Brazilian partner."
The plant will be connected to the national electric grid in mid 2017.
Earlier in 2014, Areva had launched the Bio Golden Raand biomass power plant, built jointly by the group with Dutch civil works company Ballast Nedam Industriebouw, and Finnish boiler supplier Metso Power Oy.
Till date, Areva has built 95 biomass power plants across the globe representing an installed capacity of more than 2,500MW.
Bolt Energias is focused on energy generation and trading and develops energy efficiency projects and solutions for the power generation market segment.
