Dr. Born - Dr. Ermel services

The actual basic price at electricity market as well as the additional allowance acc. to the CHP legal regulation forced considerations on side of the Mainova AG about optimized use of the existing energy potential. Aim oft he above mentioned services was to compile a technically and economically optimized plant concept both for the heating plant as well as for the adjacent energy-from-waste plant to make use of synergy effects. As a result of the extended optimization the recovery of fresh steam produced by the energy-from-waste facility AVA in an extraction condensing turbine with air condenser on-site of the heating plant was realized.

The two CHP-units utilize the biogas from the biogas plant of Hillersee PW III of the Brunswick Wastewater Board, which is 20 km away. Approx. 1,000 m³ of biogas per hour are transported via the 20-km-long biogas network of the BS Energy to the location in Oelper.
A gas supply agreement between the Wastewater Board and the BS Energy regulates all financial and legal affairs. The waste heat from the CHP-unit is fed into the existing district heating network of the BS Energy and provides heat to the Physical and Technical Federal Agency (Physikalisch-Technische Bundesanstalt), the Federal Agricultural Research Centre (Bundesforschungsanstalt für Landwirtschaft) as well as various households in Brunswick. The generated electricity is fed into the public grid of the local utility company and funded according to the EEG (German Renewable Energy Act) including renewable resources and the Technology Bonus.
