Summary/Abstract: This study investigates whether the spatial density of collective self-consumption energy communities in EU urban areas is positively correlated with enhanced grid flexibility and reduced solar PV curtailment. Using a mixed-methods approach, the research combines GIS-based spatial density mapping, statistical correlation and regression analysis, and qualitative policy review across 15 representative European cities. Results show that higher CSEC density is significantly associated with lower curtailment rates and higher flexibility scores. Cities like Ghent and Vienna exhibited the most favorable performance, supported by digital infrastructure and enabling policy frameworks. Multivariate regression confirmed CSEC density as a key predictor, independent of population or rooftop PV levels. The findings emphasize that spatial clustering of energy communities generates systemic grid benefits and should be prioritized in EU energy policy. The study concludes with strategic recommendations for spatial planning, DSO collaboration, data governance, and regulatory reform to accelerate the role of CSECs in Europe’s clean energy transition.
