Steam and heat

STEAM AND HEAT

Asnæs Power Station produces heat for the city of Kalundborg and process steam for the Statoil Refinery, Novo Nordisk A/S and for Novozymes A/S. The combination of heat and power production results in a 30% improvement of fuel utilisation compared to a separate production of heat and power.

Approximately 4,500 households in Kalundborg receive district heat from Asnæs Power Station. District heat has replaced approx. 3,500 small oil-fired units.

Statoil Refinery receives process steam and water from Asnæs Power Station. The steam covers about 15% of the refinery's total consumption of steam. The refinery uses the steam for heating oil tanks, pipelines etc. Novozymes A/S and Novo Nordisk A/S use steam from Asnæs Power Station for the heating and sterilisation of the processing plants.

Some of the cooling water from Asnæs Power Station is used by a fish farm producing 200 tonnes of trout and salmon on a yearly basis. The fish have better growth conditions in the heated water.
