Aalborg Energie Technik a/s Biomass Cogeneration Plant


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 the use of fossil fuels. This reduces CO2 emissions by 20,000 tons/year as the plant efficiency will be more than 60%.


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


The plant has been completed and commissioned in May 2015.
