What should a System Operator do when studies indicate that transmission limits will be exceeded?

When studies indicate that transmission limits will be exceeded, it is crucial for a System Operator to create Operating Plans that mitigate the predicted issues. This proactive approach allows for effective management of system reliability and prevents potential overloads that could lead to outages or damage to equipment.

By developing Operating Plans, the System Operator can implement strategies such as adjusting generation levels, redistributing loads, or coordinating with other system operators to ensure that the transmission limits are not exceeded. This planning is essential for maintaining the stability and reliability of the power grid, which is a fundamental responsibility of a System Operator.

The other options present actions that do not align with best practices for managing transmission limits. Ignoring the results can lead to severe consequences, such as equipment failure and system blackouts. Increasing the load on the system would exacerbate the problem, and requesting additional power without a clear plan may not address the underlying transmission constraints effectively. Therefore, the recommended action of creating Operating Plans is the most responsible and effective way to handle potential transmission limit exceedances.
