Real-time district heating production
See how much district heating is being produced in Vaasa right now. Our heat is primarily produced from bio- and waste energy. Additionally, we make use of a new heat storage system, from which thermal energy is transferred to the district heating network as needed. The data updates in the graphs every minute.

Real-time district heating production
Our heat is primarily local, produced using bioenergy and waste energy.
Heat storage status
We utilize a modern heat storage system that transfers thermal energy to the district heating network as needed.
How we produce
district heating
For years, we have been investing in increasingly sustainable energy solutions for district heating production. The latest addition is the massive heat storage built in Vaasa, which plays a key role in the transition towards fully coal-free production.
At the Westenergy waste-to-energy plant and the Vaskiluoto power plant, both electricity and heat are produced simultaneously. This allows us to achieve high efficiency while using fewer raw materials. These plants produce about 99 percent of Vaasa’s annual district heating needs.
The heat storage located in Vaskiluoto, Vaasa, enables the storage of heat from different production sources and waste heat. Heat is transferred from the storage to the district heating network as needed. With this storage, we can efficiently optimize electricity and heat production.
At Westenergy’s waste-to-energy plant, non-recyclable waste is utilized in the production of district heating and electricity, making waste an integral part of the energy system.
Vaskiluoto power plant is a pioneer in utilizing biomass. There, over 60 percent of the heat is produced from local biofuels, with the rest coming from peat and coal. The new heat storage reduces coal use by up to a third.
At the Påtti’s heat pump facility, the heat energy contained in treated wastewater is captured and used in district heating production. With the plant built at the wastewater treatment facility, we can produce around 60 gigawatt-hours of district heating per year, which is equivalent to the annual energy consumption of about 2,000 single-family homes. The heat stored in the wastewater is considered renewable energy. Using treated wastewater’s heat energy for district heating production is an excellent example of energy efficiency and the circular economy.
At Vaasan Sähkö’s own heat centers, district heating energy is produced during potential disturbances at the power plants. These centers are also used during the coldest periods of winter. The heat centers use light fuel oil as fuel and produce about one percent of Vaasa’s annual district heating demand.
