In 2008, this old mining city started operating a geothermal station using heat from the water used to inundate the mine shafts after the site closed. The station is divided into two sections. 825m deep mineshafts provide access to underground mine water at a temperature of 35°C. The water is used for heating purposes and is then conveyed at 17°C to other mineshafts, where it is stored before being used as a coolant. Over 400 newly-built houses, 55,000 m² of new tertiary buildings and 84,000 m² of existing office space have been equipped with heating and cooling systems using this mine water energy. The CO2 emission savings generated by this concept are estimated at 55%.
