This Nodal Protocol Revision Request (NPRR) moves the definition of Transmission Operator (TO) from the Nodal Operating Guide to Section 2.1, Definitions, of the ERCOT Protocols, revises this definition, and adds new Section 16.19, Designation of Transmission Operators, that clarifies the designation process and basic qualifications for TOs. This NPRR also replaces references to “designated agent” in Section 6.5.7.8, Dispatch Procedures, with the term “TO.”
