Aalborg Energie Technik a/s Biomass Boiler Plant

COFELY GDF SUEZ, Bio Cogelyo Normandie, France

Bio Cogelyo Normandie (BCN) Plant is a biomass-fired CHP plant with an annual fuel input of 165 000 tons of forestry-wood, and clean, uncontaminated residues from wood processing.

Performance Test

The biomass boiler plant was successfully commissioned and handed over at the end of 2011, and the official performance tests carried out by Bureau Veritas (APR 2013) achieved the following performances:

  • Boiler efficiency of an impressive: 93 %
  • In-house power consumption of <1.6 % of fuel heat input
  • Emissions below European standards

All measured performances were better than the guaranteed performances by a good margin.

Additional information

  • An interesting article has been published in Bioenergy insight (DEC 2012): “Pedalling towards CHP goals”, which explains the environmental impact of the project, GDF SUEZ Cofely Services and regulations in France and project performance. Read more.
  • Biomass has become a rapidly increasing energy source for GDF SUEZ Cofely Services, which has seen an increase in the number of projects using biomass. Most of the projects are based on wood but also on the development of energy crops and the use of cereal waste. Read more.
  • With the order from Cofely Services for the BCN project in Normandy and the focus on the French market, AET was awarded the French-Danish Trade Union Export Prize 2010 (18.01.2011) Read more.
