Askersund generates both electricity and heat. The primary fuel source is biofuel in the form of locally purchased forest biomass. In order to ensure that combustion is as efficient as possible and that emissions are as low as possible, the fuel is quality controlled through spot checks and visits to suppliers.

In 2013, the plant was fuelled around 97 per cent by forest biomass. In order to exploit the biofuel to the full, there is also a flue gas condenser which converts heat from the flue gases into district heating. In very harsh winters, we may be forced to use more oil than normal to ensure that we can supply the heat our customers require.

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.

Askersund 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.
