To be available to the electricity grid and supply power when it’s needed, you must first purchase the ancillary service from BalanceX. You can do this if you live in Zealand, Lolland, Falster, Bornholm, or one of the smaller islands such as Bogø and Fejø (DK2).
BalanceX hopes to offer ancillary services to the rest of Denmark in 2026 (DK1).
