Storing heat
Flexible energy generation
New thermal energy storage in Vaskiluoto
In 2020, a large thermal energy storage (TES) facility with 100 MW of charge and discharge capacity was put into operation in Vaskiluoto, Vaasa. It will diversify the region’s thermal energy generation both now and in the future. The power plant will carry out charging, and heat will be discharged from the TES system to be used in the region’s district heating network.
The caverns used for thermal energy storage will act as an optimisation tool within EPV’s energy generation portfolio. The facility can be used into the future, regardless of the production mode. The storage facility is therefore an excellent example of sector coupling.
