The Herning Plant is situated in the southern part of Herning and has undergone several changes since its construction in 1982. Originally a coal-fired plant, it was in 2000 converted to a natural gas-fired plant. The plant was rebuilt again in 2002, this time to be mainly fuelled with chips. Finally, in 2009, it was rebuilt to a 100 % CO2-neutral production based on biomass fuels.

The plant produces 95 MW of power and 174 MJ/s of district heating, and is able to burn wood chips and wood pellets, with natural gas and oil as reserve fuel.

Power and heat production at the Herning plant is based on the use of chips as the main fuel and wood pellets as the supplementing fuel, while natural gas and fuel oil are reserve fuels. In 2010, the proportion of chips as fuel was approx. 70 %, while wood pellets represented approx. 30 %. The Herning plant is therefore Denmark’s largest chips-based plant and annually burns approx. 280-290,000 tonnes of wood chips and approx. 70-80,000 tonnes of wood pellets.
