Before installing new relays with advanced technology on major tie lines, who should a Transmission Operator notify?

Notifying neighboring Transmission Operators and Balancing Authorities before installing new relays with advanced technology on major tie lines is crucial for several reasons. These entities are directly involved in the operation and reliability of the interconnected power systems. Communication ensures that all stakeholders are aware of the changes that could affect system operations, coordination, and reliability across interconnected networks.

Advanced relay technology might change operational characteristics, protection schemes, or system response during disturbances. By keeping neighboring Transmission Operators and Balancing Authorities informed, the Transmission Operator helps facilitate coordination measures that may be necessary to adjust operational protocols or respond to any emergencies that could arise from the implementation of new technology.

This proactive communication approach is a hallmark of established industry best practices, which seek to maintain system reliability and mitigate risks associated with operational changes. Engaging these affected parties also fosters collaboration and enhances trust across different entities involved in power system operations, which is essential for effective grid management.

While notifying regulatory bodies and the public may have its own relevance, they are not as directly impacted by specific operational changes as neighboring operators and balancing authorities. Internal staff may be informed as part of the operational protocol, but they should not be the sole focus when considering external dependencies and collaborative operational integrity.
