How long must a GOP notify the TOP of any capability changes affecting a restoration plan?

The correct timeframe for a Generator Operator (GOP) to notify the Transmission Operator (TOP) of any capability changes that may impact a restoration plan is 24 hours. This requirement ensures that any changes to a generator's operational capabilities are communicated promptly, allowing the TOP to adjust its plans accordingly. The 24-hour window is critical in maintaining system reliability and ensuring that all operators are on the same page regarding the resources available for restoring service after an outage.

Keeping the TOP informed within this timeframe helps to address potential risks and ensures that, in the event of an emergency or planned outage, the response and recovery efforts are based on the most current and accurate information about available generation resources. This requirement supports the overall reliability of the power system by fostering communication and coordination between the different entities involved in power operations.
