District heating in Oslo

From August 2017, we produce the district heating in Oslo through the company Fortum Oslo Varme. We account for about 20 % of the district heating need in Oslo, and in 2018 we produced 1.7 TWh of district heating.

Fortum Oslo Varme’s activities are an important tool for Oslo to reach its ambitious environmental- and climate goals. The company is an important part of the circular economy, while energy recovery of residual and commercial waste for electricity and district heating is reducing the city’s emissions of greenhouse gases and local pollution.

Renewable and neutral heating technology
Fortum Oslo Varme aims not to use fossil energy sources (oil and gas) under normal operating conditions and has thus invested heavily in renewable heating technology during the recent years, both bio-oil and pellet-fired boilers. It is still necessary to use small quantities in emergency situations, or circumstances that make the supply situation demanding. The share of fossil oil and gas was 1,5 per cent in 2018, which is on par with the recent years. In addition, a smaller amount of fossil oil is used as support fuel at the Klemetsrud waste-to-energy plant. In 2018, fossil oil was replaced with biodiesel as a support fuel at the production plant at Haraldrud, and the same is now being planned at Klemetsrud. Fortum Oslo Varme is subject to quota bonds in the EU’s ETS quota system.
