What is the AC/DC ratio acceptable for the scheme?

RED to determine the appropriate AC/DC ratio based on expected technical compliance stipulated in Grid Code and other GSO technical documents - as long as the required firming of 50% of GEP capacity for 4 hrs is fulfilled.

For the avoidance of doubt, the verification of this requirement is done at the commissioning stage, before commercial operation commences.

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?
