What is the dispatch priority during solar energy generation? E.g. is it to fully charge the BESS first and export to grid once BESS is fully charged or vice versa? Or is the battery mainly to help firm up/smooth out the half-hourly firm output?

The main function of BESS is to firm up GEP output to 50% of its capacity by storing solar energy in excess of 50%. Meaning that all solar energy will be exported to the grid. Depending on weather conditions and solar irradiance on a particular day, and if there is solar output more than 50% of GEP capacity, only the energy in excess of this 50% of GEP capacity will be stored in BESS and discharged later to the grid on the same day.

Are there any detailed guidelines on requirements to include community-scale battery storage? What are the components in SAC? Can lower System Access Charge (SAC) for Longer-Hour Batteries be considered? What is the System Access Charge (SAC) for Non-Solar Technologies (e.g., Biomass/Biogas)? What is excess energy?
