Increased district heating
District heating consumption increased by 4.4 per cent in 2017 compared to the year before and amounted to 5.5 TWh. Investment in district heating production and the further expansion of the district heating net has pushed up consumption over time.
In 2017, the total length of the district heating net was about 1 900 km – more than twice that of 2008.
Highest consumption in service industries
Service industries continued to account for the largest share of consumption in 2017, and their use of district heating accounted for about 3.3 TWh. A total of 23 per cent of the total district heating consumption, or about 1.2 TWh, was supplied to households, while consumption in industry accounted for 17 per cent, or barely 1 TWh.

About half of district heating is generated from waste
Net production of district heating was 6.1 TWh. Losses in the distribution net amounted to almost 0.7 TWh, which means that about 5.5 TWh district heating was delivered to consumers.
Waste incineration is the main energy source for district heating. In 2017, about 50 per cent of district heating, or 2.9 TWh was produced from waste. The second largest source of energy was waste wood facilities, with a share of around 21 per cent (1.3 TWh).

In addition to district heating, some of the plants supply district cooling. Consumption of district cooling came to 173 GWh in 2017; about 5 per cent lower than the year before.
Figure 3. Consumption of district cooling
The average price for district heating increased from 63.5 øre/kWh in 2016 to 66.7 øre/kWh in 2017. For households and the service sector, the average price was 68.9 and 73.8 øre/kWh respectively, but industry was lower, at 38.7 øre/kWh. The price for cooling amounted to 98.3 øre/kWh in 2017, which is 4 per cent higher than 2016.
Increased district heating consumption and higher prices led to higher sales revenues from district heating in 2017. The revenues from district heating increased by about 10 per cent compared to 2016 and amounted to NOK 3.7 billion. The revenue from district cooling was NOK 170 million.
