Within how long of a request must the TOP provide the criteria used to develop the voltage schedule or reactive power schedule to an inquiring GOP?

The requirement for a Transmission Operator (TOP) to provide the criteria used to develop the voltage schedule or reactive power schedule to an inquiring Generator Operator (GOP) is indeed set at 30 calendar days. This time frame ensures that the GOP receives timely and relevant information, which is crucial for planning and operations, particularly regarding how their generation resources can interact with the transmission system.

Providing this information within 30 days helps to maintain effective communication and coordination between entities, which is essential for reliability and efficient operation of the electrical grid. By having a clear timeline, both parties can ensure that the necessary data is shared promptly, supporting the overall reliability goals mandated by NERC standards.

The other options do not align with this regulatory requirement, as a period shorter than 30 days might not suffice for the TOP to adequately compile and convey the necessary criteria. Conversely, longer time frames would delay critical operational planning and coordination efforts between the TOP and GOP. Therefore, 30 calendar days is established as the appropriate balance between responsiveness and thoroughness in fulfilling this request.
