Wedoany.com Report-Jun 2, Construction has begun on the Faelledby Energy Community in Copenhagen’s Faelledby district, Denmark, featuring a neighborhood-scale energy collective powered by building-integrated photovoltaics (BIPV) and building-applied photovoltaics (BAPV). The project includes over 30,000 square meters of solar rooftops with an estimated capacity of 4 megawatts, utilizing crystalline silicon solar modules. Solartag, a Danish company, is installing BIPV on pitched roofs and BAPV on flat rooftops, with a single local energy community operator managing production, sharing, and metering.

Mikkel Karlsson, CEO of Solartag, stated: “It’s also one of the first to combine local power generation, architecture and citizen ownership in a way that’s scalable. That’s what the energy transition needs – solutions that work technically, socially, and visually.” He noted that the project represents Scandinavia’s largest BIPV-BAPV installation. A Solartag spokesperson added that the community will house up to 6,000 residents, including private homeowners and tenants in subsidized housing, with the first residents expected to move in by late 2025.

The energy collective will incorporate a 4.5-megawatt-hour shared battery bank, installed in phases and centrally managed. The spokesperson explained: “The batteries allow the community to store daytime surplus for evening use, provide local peak shaving and sell flexibility back to the national grid via market-based system services.” The system prioritizes local consumption, with 60% to 70% of generated energy expected to power homes, schools, and public infrastructure within the district.

Excess energy will be stored in the battery system when feasible or fed into the public grid through a collective feed-in agreement. The spokesperson clarified: “No traditional net metering is used. Instead, the community participates in market-based compensation schemes for surplus electricity and grid services.” This approach supports efficient energy use and grid stability without impacting trade dynamics, focusing on local energy consumption.

The Faelledby Energy Community exemplifies a scalable model for sustainable urban development, integrating renewable energy, community ownership, and modern architecture. By leveraging solar power and storage, the project enhances energy security and reduces reliance on non-renewable sources, contributing to Copenhagen’s environmental and social goals.
