n Order 888, the Federal Energy Regulatory Commission suggested 11 principles for forming an independent system operator, or ISO. In its third principle, the FERC offered this guidance on transmission pricing:
An ISO should provide open access to the transmission system and all services under its control at non-pancaked rates pursuant to a single, unbundled, grid-wide tariff that applies to all eligible users in a non-discriminatory manner.
