Formula Rate Protocols

Posted materials are organized by rate year. For transmission owners with FERC approval to use projected data (with a subsequent true-up), rates are updated annually effective January 1st. Transmission owners using historical data are updated annually effective June 1st. The initial rates for new transmission owners (or those that switch from a historical to forward-looking Attachment O) may be added outside of this cycle, but will be included in the normal annual update cycle thereafter.
