Construction of a district heating gas boiler plant in Neudorf ob Wildon, Austria. Purpose of the plant is to secure the district heat supply in the southern grid area of the city of Graz. The plant with three boilers will have a fuel heat output of 97.5 MWth at full load. The thermal efficiency of the state of the art plant will be within the range of 95% over the entire load range. Thus, the plant will have a thermal useful power of at least 92.6 MWth.
