Which of the following activities is not part of standard transmission reliability procedures?

Ancillary Service Pricing is not considered a standard transmission reliability procedure primarily because it focuses on the economic aspects of power supply rather than the operational techniques necessary to maintain the reliability of the transmission system itself.

Infrastructure upgrades, capacity assessments, and real-time monitoring are crucial activities that directly contribute to the reliability of the electric grid. Infrastructure upgrades ensure that the transmission facilities can handle current and future demands, capacity assessments help determine the available and reliable capabilities of the network, and real-time monitoring enables operators to observe the system's performance and address issues as they arise. These activities are essential in maintaining a stable and reliable transmission system, while ancillary service pricing is more about the financial management of services that support the reliability but doesn’t directly impact the technical operational standards.
