How is wheeling availability is determined?

Answer: There are a few stages to determine the wheeling availability. At the planning stage, the PSS process will determine and advise if the chosen connection node is able to connect and safely evacuate RED (capacity in MW). This shall be the default wheeling availability.

However, operationally, GSO may advise on unavailability to wheel the energy due to grid system constraints- e.g., planned or forced outages or other emergency e.g., planned or unplanned transmission outages or any other system constraints that impact the wheeling availability.

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?
