The plant, co-owned by Fortum and the city, will run on forest residues and wood waste to produce an expected 750 GWhe and 1700 GWth per year. It will provide district heating and power for 190,000 households and is expected to reduce the region’s emissions by 126,000 tonnes per year.
The plant uses 12,000 m3 of wood chips per day and features an underground storage facility with a capacity of 50,000 m3.
Construction began in 2013.
Anders Egelrud, managing director of Fortum Värme in Stockholm, said: ‘This is an important step in the development of sustainable energy solutions for Stockholm, but it is also an important showcase: many countries and cities are facing urbanisation-related challenges. Now we can provide sustainable solutions that also connect waste management, biogas production, district cooling and other aspects of a circular economy.
‘With increasing volumes of intermittent renewable energy, the demand for effect will increase during the cold and windless days. As CHP is flexible, we can adjust the production of both heat and electricity to meet the demand; this means that we will also provide a key component in the growing renewable energy system,’ he added.
