Transmission access charge options

The current transmission access charge is a two-part rate for each megawatt hour of internal load and exports and is used to recover transmission revenue requirements. Revenue requirements for facilities rated 200 kV and above are recovered through a system-wide rate, while requirements for facilities rated below 200 kV are recovered via specific rates for each participating transmission owner. This initiative considers if the same structure would be appropriate should a transmission owner with a load service territory join the ISO as a participating transmission owner.
