From around the world: Solar energy for Denmark's largest energy community
16. 8. 2025
Construction has begun in Denmark on a neighbourhood-scale community energy project that will be powered by rooftop photovoltaic systems and building-attached photovoltaic systems.
The Faelledby energy community in the Faelledby district of Copenhagen will have more than 30,000 m² of solar roofs with an estimated capacity of 4 MW.
The project will include several dozen solar roofs, each using crystalline silicon solar modules.
A single local energy community operator will manage the production, sharing and metering of all solar systems.
Mikkel Karlsson, CEO of Solartag, said that the energy community will have the largest installation combining rooftop installations with installations attached to buildings in Scandinavia.
It is also one of the first installations to combine local energy production, architecture and citizen ownership in a scalable way. A Solartag spokesperson said the community will be home to up to 6,000 residents, including private homeowners and tenants in publicly subsidised flats.
The first residents are expected to move in by the end of 2025.
The energy community will also include a shared 4.5 MWh battery bank, which will be installed in phases and centrally managed.
The batteries will enable the community to store surplus energy from day to night, balance local peaks and sell flexibility back to the national grid through market system services.
The system is designed to maximise on-site consumption, with approximately 60% to 70% of production expected to be used locally within the neighbourhood in households, schools and public infrastructure.
Surplus energy will be stored in the battery system where possible and fed into the public grid through a collective energy supply agreement.
Traditional consumption metering is not used. Instead, the community participates in market-based compensation programmes for surplus electricity and network services.
