Assumption that the max hourly interchange value reached between Jan 2019 - Dec 2023 is representative for available transmission capacity between BA's. — The TVA source indicates that all new transmission projects to Georgia, Alabama, and Mississippi are within the TVA's jurisdiction and do not connect to Southern Company Services. No planned interconnections oulined in the Ready-To-Go Transmission Projects 2023 report.
