Biogas plant Seckach supplies flexible electricity & heat

In 2006, the Green City biogas plant in Seckach, Baden-Württemberg, was realized together with farmers from the region. As part of a so-called flexibilization, the plant was converted in 2019 with the aim of supplying electricity and heat according to demand. With a total electrical output of 2,047 kW and a thermal output of 2,036 kW, as well as a wood chip drying system and a connection to the local heating network, the plant was optimized for a targeted supply of electricity and heat.

1.5 million euros were invested in flexibilization. Thanks to a second combined heat and power plant, as well as a gas storage tank, more than 2000 kilowatts of electricity and heat can be produced and flexibly controlled. The heat is supplied to the local heating network of Bürger-Energie Großeicholzheim, which can supply 122 households.

The production of biogas electricity and heat is almost CO2 neutral. Since its commissioning, the Seckach biogas plant has saved more than 52,000 t of CO2. The plant itself emits only 3% of CO2, which is used for harvesting and operation.

In August 2021, the technical managing director Reiner Wetterauer and the commercial managing director Eduard Schindler conducted an inspection and presentation at the plant. Seckach mayor Thomas Ludwig, members of the board of Bürger-Energie Großeicholzheim and local press representatives were invited. Articles were published in German in the Rhein-Neckar-Zeitung and the Fränkische Nachrichten.
