A 50 kW micro-biogas plant on a dairy farm in Sulmów near Łódź, Poland, has been recognised as a benchmark project in the country after demonstrating the ability to operate autonomously during power grid failures — a capability its designer says most agricultural biogas plants lack.
The plant, designed and built by Integrotech sp. z o.o. on a farm with around 300 cows, was awarded gold at Ferma 2026, a major Polish agricultural fair focused on livestock farming.
Piotr Łuczak, CEO of Integrotech, said the project was intended to demonstrate that biogas installations should function not only as distributed energy sources but as "stable and autonomous energy systems" — a priority he said was of particular importance in Poland given current geopolitical pressures.
The plant achieves around 95% availability and uses between 20 and 35% of the electrical energy it generates for on-site process and farm consumption, including heating farm buildings in temperatures as low as -18°C. The remaining 65 to 80% is fed into the public grid. Digestate produced by the plant is used as agricultural fertiliser.
Agitation technology was supplied by Suma, with the 630 m³ fermenter equipped with a Giantmix FR4 SP long-axis agitator configured using computational fluid dynamics simulation. A tractor-driven Giantmix Z3 HY stationary agitator was also installed as a backup, operable via a PTO shaft.
Łuczak said Integrotech's background in the gas energy sector had shaped its approach to component selection, with Suma agitators chosen on the basis of operational flexibility, ease of maintenance and whole-life costs.
