The wood-fired cogeneration plant supplies the Gropiusstadt population of about 50,000 inhabitants reliably with thermal energy in an eco-friendly manner. The use of wood reduces the annual release of CO2 by approx. 235,000 t compared with the previous situation based on coal. The wood-fired cogeneration plant is thus making a major contribution to climate protection.
