Who must be notified by the Reliability Coordinator or Transmission Operator regarding deviations?

The Reliability Coordinator or Transmission Operator is responsible for ensuring the reliability of the electric grid, which includes monitoring and responding to deviations in system conditions. When there are deviations from the expected performance or operating conditions, it’s critical that the correct entities are informed to mitigate any potential reliability issues.

In this context, purchasing-selling entities are engaged in transactions that can affect grid stability, including the buying and selling of electricity. If there are deviations, notifying these entities allows them to adjust their operations accordingly, ensuring that market dynamics support the physical reliability of the system. By providing timely information about deviations, reliability coordinators enable these entities to take necessary action to avoid exacerbating the situation or causing further issues on the grid.

While other options involve entities related to the electricity market, purchasing-selling entities are most directly impacted by operational deviations and are essential for coordinated action in response to reliability concerns.
