Falling PV prices and advances in small CHP plants make self-consumption increasingly attractive, with rooftop electricity in Germany potentially 40% cheaper than grid power within four years. While current discussions focus on single-family homes or small industries, most Europeans live in apartment buildings, and many offices host multiple companies. Separate PV systems per unit are costly and impractical; combined generation with shared electric or thermal storage at the building level offers efficiency gains. This approach reduces losses, optimises storage capacity, and enables broader participation. The study examines organisational, legal, technical, and financial aspects, and suggests regulatory measures to support building-level captive power supply.
