New electric boiler commissioned in Toppila – Oulun Energia’s electric boiler capacity now 100 MW

19.08.2025 / Last updated 00:00

Our new 60-megawatt electric boiler has been completed at the Toppila power plant site. Oulun Energia now operates two electric boilers with a combined capacity of 100 megawatts.

In simple terms, the operation of the electric boiler is based on heating water in the boiler, which produces steam and heat. The steam is directed to local industry needs and the heat to the district heating network to heat properties in Oulu. 

The benefits of the electric boiler can especially be seen during electricity price fluctuations. It is used when electricity is cheap.

In 2024, nearly five percent of Oulun Energia’s district heat was produced using electric boilers. Over the year, the boiler also replaced approximately 1,000 truckloads of solid fuels, such as wood and peat. With the new Toppila boiler, we expect the production volume to double.

Investments in electric boilers are part of Oulun Energia’s strategic goal to reduce combustion-based energy production and maintain the competitiveness of district heating.
