UPM Energy, Finland's second-largest electricity producer, is investing in an ultracapacitor system at the Kuusankoski hydropower plant, marking the second phase of its innovative project.
Set to be operational by summer 2025, this installation follows a successful pilot at the Katerma hydropower site in 2022.
The ultracapacitor system will enhance UPM Energy's ability to provide rapid response reserves through short-term energy storage, addressing grid balancing needs in milliseconds. This capability is crucial as grid operators face challenges from the increasing volatility of weather-dependent renewable energy sources like wind and solar power.
Antti Raukola, project manager at UPM Energy, emphasized the technology's importance for future grid balancing, noting its proven effectiveness at Katerma. Ultracapacitors offer high power discharge capabilities and quick response times without capacity loss, making them a sustainable alternative to traditional batteries.
With 99% of its electricity generated from CO2-free sources, UPM Energy is committed to supporting Finland’s energy transformation. This ultracapacitor project is a significant step toward a sustainable, zero-carbon future.
