Is a RED permitted to sign FCAS (Frequency Control Ancillary Services) agreements with the grid operator for a qualifying BESS system developed within a solar farm, as well as for standalone projects?

There is no requirement to sign ancillary services for the development of BESS. However, there are sets of technical, control, and monitoring requirements that BESS has to comply with for hybrid and standalone BESS.

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?
