Heat from bioenergy for the inhabitants of Perg

The long-distance heating network fed by a biomass plant has been expanded, providing more customers with affordable and sustainable energy.

An additional 3.5 km of pipes installed between 2009 and 2011 has brought the length of the entire network to 16 km, providing heating for more than 250 customers. Not only private customers, but also public buildings, schools, and companies are supplied with energy produced from wood waste from the large Upper Austrian forests.

Environmentally friendly energy produced from local resources

The biomass plant, which is run by Bioenergie Perg GmbH, uses mechanically shredded wood as its main resource. The wood comes from local forests, and consists of pieces which cannot be used by the timber industry and would otherwise go to waste, such as treetops, broken pieces, and small rests. The biomass plant’s two kettles, with a power output of 2 000 and 5 000 kW respectively, burn between 25 000 and 30 000 m3 of wood chips per year.

Producing energy from local biomass has a double benefit. The use of the renewable resource wood means that the carbon dioxide (CO2) which is released into the atmosphere during the process was previously stored by the trees through photosynthesis, and no additional greenhouse gases are freed – a significant advantage over fossil fuels. In addition, wood is a local resource, and transport is kept to a minimum.

Energy security for the future

The second major benefit of the biomass plant concerns the stability and security of the resource. Upper Austria’s large forests can be expected to provide sufficient raw material to produce heat for the inhabitants of Perg in the long term. The price volubility of wood is also significantly lower than that of fowwil fuels.

Wood waste as biomass is a promising source of renewable energy. Bioenergy Perg has therefore received continuous support from the region of Upper Austria and from the European Regional Development Fund (ERDF), which not only supported the network expansion, but also the original construction of the Perg biomass plant in 2006. The project has also seen follow-up support, with the ERDF co-financing another expansion of the distance heating network which connected 40 additional customers. The second expansion was finalised in 2013.


Total investment and EU funding

Total investment for the project “Bioenergy Perg – network expansion” is EUR 759 640 with the EU’s European Regional Development Fund (ERDF) contributing EUR 163 552 through the “Upper Austria” Operational Programme for the 2007-2013 programming period under priority axis 1, “Knowledge base and innovation”.
