What is the first action a Reliability Coordinator should take when declaring a TLR to prevent a potential problem?

When a Reliability Coordinator identifies a potential problem that may require a Transmission Loading Relief (TLR), the first action they should take is to contact the other Reliability Coordinator to confirm the situation. This step is crucial because it ensures that both parties have a shared understanding of the issue at hand and helps to effectively coordinate responses to mitigate the risk of system overload or instability. Communication between Reliability Coordinators is essential for maintaining system reliability and ensuring that all operators are aligned in their responses.

While initiating system-wide communication or issuing a public alert can be important actions, they typically follow first confirming the problem with the other Reliability Coordinator. Likewise, consulting with regulatory authorities might be necessary later in the process, but it is not the immediate initial action. The priority should always be on collaboration and verification of the current system conditions with another Reliability Coordinator before taking broader actions.
