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 now 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 90,000 tonnes/year as the plant efficiency will be more than 60%.

 

The biomass-fired cogeneration plant has an annual fuel input of 150,000 tonnes of forestry wood, and uncontaminated residues from wood processing and DerTal. DerTal is a tall-oil and by-product from DRT.

 

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 2015.
