Efficient use of waste wood
The biomass facility will be capable of using waste wood as fuel and will be generating 40 MWe of renewable energy. With an annual combustion of 325,000 tonnes of wood waste, the plant will be able to supply 78,000 households with electricity. The contract was signed in the early autumn of 2015, and the plant is expected to be completed in the first quarter of 2018.
