If a third-party reviewing TO/TOP security plan recommends changes, how long does the TO/TOP have to modify the plan or provide reasons for no modifications?

The timeframe for a Transmission Owner (TO) or Transmission Operator (TOP) to modify their security plan or provide reasons for not modifying it, after receiving recommendations from a third-party review, is 60 days. This requirement is aligned with the protocols established under NERC regulations, which aim to ensure that TOs and TOPs maintain effective security measures. The 60-day period allows these entities sufficient time to evaluate the recommendations presented, assess the feasibility of implementing the changes, and address any operational or regulatory considerations that may impact their security plan. This structured timeline helps maintain accountability and encourages timely updates to security practices, contributing to the overall reliability of the electric grid.
