The design & build of the process package of the Sinnamary biomass plant in French Guyana for VOLTALIA 


BOCCARD & BERKES are proud to be selected by VOLTALIA for the design & build of the process package of the Sinnamary biomass plant in French Guyana.

The new biomass power plant, with a capacity of 10MWe (40MWth), is located near the Petit-Saut dam in Sinnamary, French Guyana:
centrale biomasse de Sinnamary en Guyane 1

points clés

From 2025, it will cover approximately 5% of the territory's electricity needs
It will use woodchips from underwater dipped logs upstream of the dam
It will thus contribute to the decarbonization of Guyana's energy mix
BOCCARD and its boiler partner BERKES are in charge of the process package for this project (studies, manufacturing, supply, assembly and commissioning):

- BERKES BWE technology boiler - water cooled vibrating grate, producing superheated steam at 78.5barg and 525ºC
- Condensing turbine 10.5 MWe
- All the water-steam cycle and utilities (air-condenser, demineralised water, condensate management, effluent management, fire protection, emergency unit, etc.)
- All the instrumentation, electricity (HV-LV) and control systems required to operate the plant

This is the second project carried out by the BOCCARD-BERKES consortium for VOLTALIA in French Guyana, after the 5MWe CACAO power plant successfully commissioned in 2021.

Ignacio Mendez, Energy Division Manager at BERKES declared: 

« After an extremely positive experience together with our partner Boccard on the CACAO biomass plant, which has been successfully running since beginning 2021, we are extremely proud that VOLTALIA has trusted once again in BERKES for the Sinnamary Project in French Guiana. It will be a state-of-the-art installation, which will include our BWE vibrating grate technology (from our subsidiary company Burmeister & Wein Energy in Denmark) as combustion system, allowing us to continue our efforts to contribute to the green economy by producing clean and sustainable energy as well as protecting the environment. It is a great honor for our company and our team to begin this second project with a professional and reliable client as VOLTALIA »

Sébastien Kouyoumdjian, Director of Advanced Energies & Industries Business Unit at BOCCARD declared : 

« After the success of the CACAO biomass power plant, BOCCARD is honored of the renewed trust by VOLTALIA to build the SINNAMARY biomass power plant and to thus contribute to the sustainability, securization, and decarbonation of the Guyanese territory energy mix. It demonstrates the solidity of BOCCARD offer and its integrated industrial model to design and build high-performing and reliable thermal power plants globally.”
