Biomass cogeneration plant – Traunreut (Bavaria)

Project description

The Traunreut biomass cogeneration plant is part of the Traunreut energy network. It all started with an idea from Bosch und Siemens Hausgeräte GmbH (BSH) to place its energy supply operations in the hands of an experienced contractor. They wanted the electricity to be generated efficiently and in an environmentally friendly manner using cogeneration from renewable sources.

The plant will incinerate up to 50,000 tonnes of class AI to AIII waste wood per year. The heat to supply the district heating network in the north of the city now comes from the biomass cogeneration plant. The electricity generated here will be fed into the grid on a feed-in tariff basis under the Renewable Energy Sources Act (Erneuerbare-Energien-Gesetz, EEG), and could supply the entire town of Traunreut with its approximately 22,000 residents.

Since commissioning, heat extraction from the biomass cogeneration plant has covered the residual heat requirements of BSH, the local heating network and other individual commercial customers. In addition, the municipal utilities are also taking heat for a newly developed district heating network in the south of the town.
