INNSBRUCK / AT

Since mid-2014, Innsbrucker Kommunalbetriebe AG (IKB) has been working on smart city solutions for Innsbruck as part of the EU SINFONIA project. The focus is on developing intelligent solutions for the decentralized generation and distribution of electricity and heat. Our third Reversepowerplant to date was built at the Rossau energy center site in 2017 as a SINFONIA sub-project. This plant generates electricity, heat and green coal from forest residues . The energy generated from renewable sources is used by the plant itself and is also fed into the district heating network. The aim is to supply all customers with as much renewable energy as possible.

As one of SYNCRAFT's first Reversepowerplants , the system was completed in just 4.5 months. It has an electrical output of 261 kW and a thermal output of 395 kW and is equipped with three drivable drying boxes in which the low-temperature heat generated is used to dry the fuel required. Commercially available wood chips with bark and fines are used to operate the backwards power plant.
