DISTRICT HEATING
Ambition: Strengthen our position as one of the two largest district heating
players in Norway and develop existing assets in Sweden.
Our starting point:
Total generation of 920
GWh of heating and
cooling, of which 560 GWh
is generated in Norway.
Strategic rationale:
Market attractiveness due
to expected growth within
waste- and bio-fuelled
district heating in Norway.
Value creation due to
competence in district
heating.
Growth target
1,340 GWh within 2017

PRINCIPLES OF DISTRICT HEATING
Return water to
heating plant.
Temperature range
45 – 75 C
Heating plant
Heating of circulating water by
combution of waste, biomass,
biogas , fossil oil or gas or by
electricity.
Circulation pump
Customers
Supply of energy according to
demand
Forward water to
customer.
Temperature range
80 – 120 C
BUSINESS PRINCIPLES (1)
- The economic basis:
The economic basis for building and operating a district heating
system is that the total cost for district heating must compete
with the customer alternative energy cost which normally is the
price for electric power and/or oil. District heating delivers
energy services to a free marked in competition with other
energy sources.
