In 2010, the company NGT Contracting GmbH has signed a 15 year energy contract with UGOS in Bad Driburg. This contract includes the delivery heat, power and steam to the Gräflicher Park Hotel & Spa and two hospitals.
A large part of the heat and power supply is generated by SOKRATHERM compact CHP units of which two GG 237 units have been installed in 2011. The (German) article published in summer 2011 in the BWK magazine can be read here.
Two years later in 2013, the CHP scheme has been enlarged by an additional GG 140 unit. The total power of the CHP scheme is 620 electrical and 960 kW thermal power. In the same year NGT has joined the large Berlin utilities company GASAG and changed its name to GASAG Contracting GmbH.
