Capacity in total 1,250 m3/h raw biogas (equivalent 2,650 kWel. ) Biomethane upgrade 700 m3 raw biogas/350 m3 biomethane 

Total power production of the CHP 1,125 kWel.
(625 kWel. 2G Jenbacher Gas engine, 2 x 265 kWel. 2G Agenitor Gas engines) 

Plant operation 

3 shareholders own and operate the biogas plant and the CHP units. The engines are used as follows: 

Two different digestion lines supply the three CHPs, the bigger one right at the farm, and the two satellite CHPs with 250 kWel. each. The lower temperature from the cooling circuit of the Jenbacher CHP is used to heat the digesters. The exhaust temperature of the engine, which is between 400°C and 500°C, is used by the biogas upgrad- ing system. 

The two satellite CHPs, based in a nearby town, supply amongst others a school, a retirement home, the fire brigade and a sanitary company with energy. The connection of 100 additional homes is already planned. 

The Arcanum Energy Systems GmbH & Co. KG is in charge of the upgrading system (an amine gas treatment system) and is also re- sponsible for the biomethane marketing. 

The biogas plant contributes about 30 Mio. kWh per year to a bio- methane pool, where several municipal utilities take part in. The utilities need the biomethane for different combined heat and power projects. By participating in the biomethane pool, the utilities can invest in the upgrading system together and provide the amounts as required without having to build an own plant. The farmers benefit from constant sales of their raw biogas.
