Electric boiler

Increasingly competitive heat production

We are expanding our emissions-free heat production and building an electric boiler and thermal battery for the Martinlaakso Power Plant. The construction of the 60-MW electric boiler and the 700-MWh thermal battery for the Martinlaakso Power Plant site is a continuation of our investments in increasingly competitive heat production. District heating produced with renewable electricity is an excellent way to take advantage of price fluctuations in the electricity market and produce emissions-free heat for the district heating network. 

Electric boiler as a new production form

The industrial-scale electric water heater is a new production form in Vantaa Energy’s heat generation portfolio. The thermal battery will be able to store hot water. Work on the project got underway in autumn 2023 and the boiler and thermal battery are scheduled for completion in late 2025.

“It is strategically important for us to ensure that energy is circulated as smartly as possible. One way to think of it is turning cheap wind power into heat to warm the homes of Vantaa residents. Once the Seasonal Thermal Energy Storage project is realized, we could also store wind power in our huge storage facility. We’ll be able to produce heat with electricity when it is cheap and with other means when electricity is expensive. This will enable us to be the most competitive form of heating for the people of Vantaa,” explains Business Director Kalle Patomeri.

In addition to electric boilers, heat produced with electricity will be added to the various waste heat sites, allowing the output heat to be raised to the temperature of the district heating network by using heat pumps.
