Engineering services for a Biomass CHP Plant in Heidenrod

Zentrum für Ressourcen und Energie (ZRE)


Naturenergie Heidenrod GmbH has been operating a biomass cogeneration plant (BMKW) since November 2013 in Heidenrod.

The biomass power plant uses exclusively natural, so-called renewable raw materials (NawaRo), such as freshly harvested timber, tree, and green wastes and cutting good from landscape care.

The plant is designed for an annual capacity of approx. 32,000 tonnes of biomass from the immediate surroundings. Steam is produced in the power plant with a turbine/generator set which produces electricity.

The electrical output of the plant is 2.75 megawatts, which generates approx. 22 million kilowatt-hours of electricity per year in full operation. The electricity is fed into the public grid. Approx. 5,500 households (2 to 3-person household) can be supplied with this electricity.


  • Feasibility studies with different output values
  • Circuit calculations for different boiler concepts and turbine suppliers
  • Determination of the layout concepts according to economical and technical criteria
  • Evaluation of an existing feasibility study for a district heating concept
  • Assistance in the allocation of plant construction in lots
  • Coordination of different plant engineers and technical coordination meetings
  • Preparation of the approval documents in accordance with BImSchV (German Federal Emission Control Ordinance)
