A coal mine in Poland fuels a 2 MW AB cogeneration plant.
Polska Grupa Górnicza has decided to turn risk into opportunity. The methane naturally produced during mining activities is a threat to miners, so in 2013 the company decided to install a 2 MW cogeneration plant. The methane is extracted from the mine and conveyed to the plant, and the electricity produced is used to power the machinery. The heat produced, meanwhile, supplies the office heating system and a nearby residential area.
