At our site in Dollbergen/Lower Saxony, we are building a biomass power plant with Koehler Renewable Energy GmbH.
The biomass combined heat and power plant planned on the basis of the Renewable Energy Sources Act (EEG 2017) is scheduled to come online in May 2020 and produce approximately 67,860 megawatt-hours of electricity.
In Dollbergen, natural wood is burned, which simultaneously generates electricity and process steam using combined heat and power technology. The plan is to use landscape conservation wood, roadside wood, forest residue from mechanical processing, wood chips, and industrial residual wood, as well as screen overflow from composting. Approximately 130,000 tonnes are required per year.
The advantage of the location directly next to the customer AVISTA OIL, the supply of steam to the customer, and the high level of expertise of the partners in the development, planning, and operation of biomass plants make this project extremely attractive.
The total investment amounts to €42 million.
