Assessment of the viable scenarios for deploying BESS within Renewable Energy Communities in Cres Island

This study presents an assessment of the potential role of a BESS (battery storage system) in selected households with installed PV systems operating under the self-consumption schemes, as well as within a new REC, considering the current transition from the net metering to the billing scheme. 

In this sense, an assessment of the effectiveness of the current (and potential future) installed PV and BESS capacity to maximise self-consumption and energy community revenues has been performed, using a modelling approach proposed by the Secretariat technical team and targeting a suitable techno-economic viability to: 

• Validate whether, under the new Croatian self-consumption remuneration approach (based on net-billing), the maximisation of RES self-consumption through BESS integration is viable.
• Evaluate the potential increase of the installed PV as well as the possibility of BESS installation to make self-consumption more effective and potentially offer, through REC storage, flexibility opportunities for the whole island electric system.
