When voltage issues are identified on a critical tie-line, what should the Reliability Coordinators focus on?

Focusing on establishing voltage control procedures is crucial when voltage issues are identified on a critical tie-line, as it directly addresses the need to manage and maintain voltage levels within acceptable limits. Effective voltage control procedures will involve implementing measures such as adjusting reactive power support, optimizing generator outputs, and coordinating with neighboring entities to ensure that voltage levels remain stable and reliable across the transmission network.

In the context of reliability, establishing these procedures helps to mitigate potential cascading failures and interruptions that could arise from voltage instability. It's also essential for maintaining the overall health of the grid and ensuring that electricity is delivered efficiently and safely to consumers.

While increasing generation capacity, training operators, and contracting external consultants can all be components of a broader approach to grid management, they do not specifically target the immediate need to manage voltage levels on a critical tie-line. Instead, the focus should be on operational strategies that can be quickly implemented to ensure voltage stability and compliance with reliability standards.
