The last week before Christmas Endre came home from comfortable temperatures in Turkey, Ole Jørgen and Magnus came home from 30 degrees celcius in the Philippines and Peru respectively and they all had to rush and find their warm winter jackets at soon as possible. Per and Sunniva on the other hand was getting quite used to temperatures around – 10 in Oslo, so when they all met for a traineegathering it felt very natural to learn more about district heating in the cold winter land of Norway.

Statkraft is all about providing pure energy, however this does not only cover hydropower and wind energy but also bio energy through district heating. District heating is about heating water. We went to visit Statkrafts innstallation at Haugerud Varmesentral in Oslo. In practical terms, a district heating plant can be compared with a central heating installation that provides one or more buildings with hot water. Haugerud varmesentral serves more than 1200 homes in two large housing cooperatives with heating. Customers use the water for heating through piped underfloor heating or radiators and for heating tap water.

Haugerud Varmesentral use bio pellets to fuel their boiler.
Haugerud Varmesentral use bio briquettes to fuel their boiler.

The station provides bio fuels as base load with a 3,5 MW boiler. In addition the station as oil and el boilers for peak load. The bio share is approx. 85% of more than 16 GWh yearly production.

For those of us that works in an office all day long, this was a very interesting and useful excurtion. We went home well assured that the people at Haugerud would get hot water for Christmas eve.
