In Storvreta, north of Uppsala, we supply largely carbon-neutral district heating. The heating plant has two 2 MW furnaces fuelled with biofuel. There is also an oil furnace in Ärentuna school for back-up and peak load.

The fuel used is 97% wood pellets, with light oil for back-up and peak load. A large water-filled underground rock cavity is used for heat storage and can deliver 8 MW.

District heating is an efficient choice

In densely populated areas, district heating constitutes an efficient use of resources and helps to minimise emissions during production. District heating can be produced from several fuel types – fuels that might otherwise not be utilised. District heating contributes to lowering emissions and using resources (that may be difficult to use in other ways besides as fuel) more efficiently.

District heating is used in 270 of Sweden’s 290 municipalities and accounts for half of all heating in households and commercial properties. District heating is the most significant reason why Sweden has been able to reduce its carbon dioxide emissions.

Storvreta is Reko-certified

The Swedish trade organisation Svensk Fjärrvärme has developed a quality assurance system called Reko for suppliers of district heating. Vattenfall’s district heating has met the requirements of this quality system since 2006. The purpose of the Reko certification is to strengthen the position of customers and to improve the relationship between customers and suppliers. The focus is on openness, comparability and trust.
