Enhancing Energy Self-Sufficiency and Economic Feasibility through Integrated PV Systems, Battery Storage, and Demand-Side Management: A Comparative Analysis Across Mediterranean Public Buildings

This study examines the potential of load flexibility activities to enhance energy efficiency and self-sufficiency in public buildings. Through comprehensive data sensitivity analysis captured from 6 pilot sites in 4 countries in the MED region, we explore the implementation of load flexibility in tandem with photovoltaic systems and energy storage. Results indicate a significant opportunity for improved energy autonomy, notably through strategically managing energy consumption patterns. Pure self-consumption scenarios, evaluated under different conditions, suggest that even marginal adjustment in load management can yield substantial improvements in energy efficiency and self-sufficiency ratios. This research contributes to the growing body of knowledge in energy management, emphasizing the untapped potential of load flexibility as a key driver for achieving greater energy independence in public infrastructure.
