Which of the following entities is NOT subject to Standard EOP-008?

Standard EOP-008, which pertains to "Critical Infrastructure Protection - Physical Security," defines the requirements for entities involved in ensuring the reliability of the bulk electric system. The primary focus of this standard is to establish protocols for various operational roles that deal with the reliability and security of the electric grid.

The Transmission Owner is not directly responsible for operational functions related to real-time system operations, such as those managed by Reliability Coordinators, Transmission Operators, and Balancing Authorities. Instead, the Transmission Owner's responsibilities are generally focused on the physical infrastructure of the transmission system, maintenance, and management, rather than the immediate operational oversight needed to comply with Standard EOP-008.

As such, the Transmission Owner does not have the same obligations under this particular standard as the other entities mentioned, which are deeply embedded in the day-to-day operations and situational awareness of the electric system. The other entities (Reliability Coordinator, Transmission Operator, and Balancing Authority) are all actively involved in real-time operations and coordination, which directly aligns with the focus of EOP-008.
