Europe’s largest forest biomass-fired CHP plant

– being built in Vienna, Austria



Siemens Power Generation (PG) is building what is said will be Europe’s largest forest biomassfired CHP plant, in Vienna, Austria. The plant is being built for WIEN ENERGIE Bundesforste Biomasse Kraftwerk GmbH & Co. at a cost of over €50 million and is due to be commissioned in the summer of 2006.

The plant will thermally recycle up to 200,000 tonnes of timber per annum, have an electrical capacity of 24.5 MW and also feed a maximum of 37 MW of district heat into the city’s supply network. The new plant will be capable of supplying almost 50,000 households with electricity and approximately 12,000 with district heat, says Siemens.

With nearly 4 million hectares of forest, some 47% of the country’s surface area, Austria is among those European countries with the highest density of forests.

Siemens PG is the general contractor for the overall project, supplying the steam generator, fuelhandling system, steam turbine generator and flue gas cleaning system with catalytic reactor. Delivery and installation of the entire electrical and instrumentation and controls equipment, and integration of the plant into the existing power plant infrastructure are also part of the order.
