Who has the authority to authorize changes in voltage schedules?

The authority to authorize changes in voltage schedules lies with the Transmission Owner. This is because Transmission Owners are responsible for managing the physical infrastructure of the transmission system, including voltage levels, and ensuring that the transmission grid operates reliably and efficiently. They have the necessary expertise and oversight capabilities to make decisions about voltage adjustments based on real-time conditions, system stability, and operational needs.

While other roles, such as the System Operator, Generation Manager, and Market Operator, play important functions within the electricity market and the operation of generation assets, the specific responsibility for approving changes to voltage schedules is distinctly aligned with the Transmission Owner’s duties. This role is primarily centered on maintaining the integrity and performance of the transmission system, thus placing them in the best position to make these critical decisions about voltage.
