Aalborg Energie Technik a/s Biomass Cogeneration Plant

ENGIE Cofely, BES VSG, France

DRT, a world leader in the development of resin and turpentine extracted from pine resin, receives steam from the Biomass Energy Solutions VSG (BES VSG) plant.

The cogeneration plant is owned by a special project vehicle (SPV), which was created by DRT, ENGIE Cofely and Caisse des Dépôts. These partners have financed, built and operates the cogeneration plant for a minimum of 20 years, utilising local biomass.

The plant produces 97 GWh of electricity/year and 214 GWh of steam/year without using fossil fuels. This reduces CO2 emissions by 20,000 tonnes/year as the plant efficiency will be more than 60%.

 

The biomass-fired CHP plant has an annual fuel input of 150,000 tonnes of forestry wood, and clean, uncontaminated residues from wood processing.

 

Performance Test

The performance of the boiler was successfully tested by Bureau Veritas in 2015:

  • Boiler efficiency: 93.3%
  • In-house power consumption: only 1.6% of fuel heat input
  • Emissions well within stringent, French standards.

The plant was completed and commissioned in May 2015.
