Denmark’s largest energy community is currently under construction in Copenhagen’s new district, Fælledby. The project includes more than 30,000 m² of solar rooftops with a total capacity of approximately 4 MW. It combines Solartag’s integrated solar roofs (BIPV) on sloped roofs with rooftop-mounted solar panels (BAPV) on flat roofs.
Fælledby Energy Community will be a groundbreaking example of how local green energy production, modern architecture, and citizen participation can go hand in hand. The project paves the way for the sustainable neighborhoods of the future, where energy is produced locally and shared among residents.
Scandinavia’s Largest Building-Integrated Solar Installation
“This will be Scandinavia’s largest combined BIPV-BAPV installation and one of the first projects to unite local energy production, architecture, and citizen involvement at scale,” says Mikkel Karlsson, CEO of Solartag. “These are exactly the kinds of solutions the green transition needs – technically robust, socially rooted, and aesthetically refined.”
Project Facts
Location: Fælledby, Copenhagen
Solar area: >30,000 m²
Capacity: approx. 4 MW (BIPV + BAPV)
Residents: Up to 6,000 (private and social housing)
Shared battery storage: 4.5 MWh (installed in phases)
Local usage: 60–70% of the production is expected to be used locally for housing, schools, and public infrastructure
Grid integration: Surplus energy is sold via market-based agreements (no traditional net metering)
A New Model for Energy Communities
The energy community is managed by a local operator who handles energy production, sharing, and billing for all participants. A shared 4.5 MWh battery stores excess solar energy for evening use, reduces peak loads, and sells flexibility back to the grid.
Approximately 60–70% of the produced energy is expected to be used directly within the district. Surplus electricity is stored in the battery or sold to the grid through collective agreements, creating an efficient and future-proof local energy system.
The first residents are expected to move into Fælledby by the end of 2025. The project will stand as a powerful example of how citizen-driven energy communities can scale and contribute to Denmark’s green future.
