Is a Bess project ready to build in Sievi?

One of the largest publicly announced BESS projects in Finland has achieved ready-to-build status in Sievi. Renewable energy projects developed by Korkia and Semecon Oy in the Sievi region, Finland, are progressing, as a legally valid building permit has been granted for a planned Battery Energy Storage System (BESS) in Kukonkylä.

How will a new battery energy storage system help the Finnish grid?

After the start of commercial operations in 2026, the project will contribute an important balancing function to the Finnish grid, supporting the Finnish renewable energy expansion. The groundbreaking ceremony took place in the afternoon on Monday the 26th of May on the site near Nivala where the battery energy storage system will be built.
