Vattenfall Eldistribution placed the Arholma Island electricity system into full operation in its microgrid-enhanced configuration when the Arholma microgrid was inaugurated in August 2023. The system, connected at the 11 kV point of common coupling to the mainland submarine cable, incorporates two 160 kW / 336 kWh lithium‑ion battery energy storage units, a small 2.73 kWp solar PV installation, and a central energy management system, enabling the island to operate autonomously for short periods during mainland outages and thus marking commercial operation of the upgraded Arholma Island Cable link and microgrid.
