Heating and decarbonisation
Decarbonisation
The green transition took a concrete leap on 1 April 2023, when the Hanasaari B power plant that had served the residents of Helsinki for nearly 50 years was decommissioned. As the power plant used coal as its main fuel, its decommissioning cut carbon dioxide emissions significantly and enabled a major leap towards the goal of carbon neutral energy production by 2030. The impacts of the decommissioning are not negligible at the national level either, as in its final years, the power plant produced about two per cent of Finland’s emissions.
In the future, Helsinki will be heated with decentralised energy production, and the heat will be recovered from several sources: land, air and water. Helen Oy aims to make its energy system carbon neutral by 2030 and to phase out incineration by 2040.
Helsinki will switch from a system based on fossil fuels to electrified heat production, with waste and environmental heat, electric boilers and sustainably produced bioenergy at its core. The homes and properties in Helsinki are heated by, for example, the Katri Vala heat pump plant, which produces renewable district heating and cooling from purified wastewater. In addition, the peak demand for district heat is balanced out by promoting smart heat management in properties.
