Around 20 years ago, Murauer Stadtwerke started thinking about investing in renewable energies. At that time, the implementation was still a difficult endeavour, but the ambition and perseverance paid off and was even recognised with several awards, such as the International Foodtec Award 2015 (in gold) for the conversion of thermal energy systems. The construction of the Murau-Stolzalpe local heating plant in 2011 was crucial for this conversion.
A 5 MW hot water boiler from Burkhardt's partner Agro Forst- und Energietechnik was installed in the heating plant, which is supplied via two wood chip silos. The silos can be filled directly with the woodchippings, which are sourced exclusively from the region, thanks to the unique construction method on the slope. The resulting heat is channelled to the respective customers via an 11.2 km long local heating network.
One of the first heat consumers was the Stolzalpe regional hospital, which is approx. 2.2 kilometres away. A short time later, the Murau brewery and its neighbouring buildings were connected to the local heating network. Thanks to a special energy swing and the use of new brewing kettles, the entire brewery was able to switch to local heating, making it the first brewery in Europe to carry out the brewing process at temperatures below 115 °C.
Due to the increase in heat consumers and to ensure a continuous base load, Nahwärme Murau-Stolzalpe decided to retrofit the heating plant with combined heat and power systems from Burkhardt - three V3.90 pellet-wood gasifiers and ECO 165 HG CHP. These highly efficient systems supply a total of 495 kW of green electricity and 780 kW of heat to the electricity and heating networks. One of the existing silos will be used as a pellet store.
