Promoting Energy-sharing Communities: why and how? Lessons from a Belgian Pilot Project

This paper explores why energy-sharing communities need policy support via network tariff adjustments and how to optimally design that support. Findings from a case study indicate that, even with high self-consumption, the energy-sharing model may not ensure participants reach break-even. Counterfactual analyses, using machine-learning techniques, indicate that capacity-term adjustments alone had minimal im-pact on peak consumption. Policy recommendations suggest limiting capacity-term adjustments to communities capable of actively managing peak loads through real-time data and flexible assets.
