Nala Renewables interim CEO Remy Verot said: “We are delighted to have closed this ready-to-build project with Fu-Gen, who have demonstrated their expertise throughout.
“Finland is a strategic market for BESS in Europe with a strong business case and we are delighted to continue expanding our footprint in the Nordics.”
Nala and Fu-Gen have a history of implementing energy storage projects in the Nordic region.
In July 2024, Nala signed an agreement to acquire a 61MW-peak solar photovoltaic project in western Romania from renewable energy group Monsson.
