On the island of Arholma, in the Stockholm archipelago, we’ve installed a microgrid to test new technology for a more reliable and sustainable energy supply. This smart local energy system uses solar panels and battery storage, balancing local production, storage, and consumption. The microgrid can operate independently during outages, ensuring continuous power. #fossilfree #fossilfreedom #breakfree #sustainability #environment #solar #innovation #Arholma #sweden | Vattenfall
