Akuo Energy - CBN, Novillars, France

The biomass-fired cogeneration plant was constructed at the Gemdoubs Paper Mill in Novillars, Eastern France.

The biomass-fired cogeneration plant was developed by Akuo Energy and is located at the Gemdoubs paper mill under the project name Cogénération Biomasse de Novillars (CBN). The plant is fuelled with wood and sawmill residues sourced within a radius of 100 km from the plant.

 

Gemdoubs' interests were to reduce and stabilise cost of energy by substituting gas with biomass and to continue the strengthening of its green profile. The drivers for Akuo Energy were to accomplish the project, initially started in 2007, to continue the build-up of their biomass business unit, to pursue the CRE 4 tender for projects with high efficiency (60%) and to create local jobs.

 

On a yearly basis, the CBN plant generates 153 GWh of green electricity equivalent to the annual consumption of 105,000 people and 215,000 tonnes of steam, which was previously produced on fossil fuels. In total, the CO2 emission is reduced by 77,000 t/year.

 

Technology, EPC and O&M by AET

AET was chosen as technology supplier and EPC contractor due to our many successful reference plants with the AET Combustion System and AET Biomass Boiler installed. These systems operate with low flue gas emissions and high efficiencies. This meant, that the selection of AET was a safe decision for Akuo.

 

As AET also has solid references on EPC and O&M, the advantage of placing these contracts with the technology supplier was utilised.

 

In this way, the risk for the investors (Akuo Energy, Caisse des Dépôts, CAM Energie, Gemdoubs, Crédit Agricole) was considerably reduced, as the number of interfaces and handovers were reduced.

 

As turnkey supplier, AET designed, supplied, constructed and commissioned the following scope:

  • Fuel feeding and AET Fuel Dosing System
  • AET Combustion System with AET Spreader Stoker and AET BioGrate
  • AET Combustion Air System
  • Natural gas burner
  • AET Biomass Boiler with superheaters and economisers
  • AET SNCR DeNOx System
  • AET Steam Air Preheaters
  • Bag filter
  • Flue gas system and stack
  • Ash handling system
  • Steam turbine generator set
  • Air cooled condenser
  • Water cooled condenser
  • Water/steam system
  • Water treatment plant
  • Air compressor system
  • Platforms and stairs
  • Boiler house and turbine hall
  • Instrumentation
  • PLC control system and SCADA system
  • 16½ year’s operation and maintenance contract.
