Which entity must provide information about generator step-up transformers to the Transmission Operator?

The Generator Owner is responsible for providing information about generator step-up transformers to the Transmission Operator. This is essential because the generator step-up transformer plays a crucial role in connecting the generator to the transmission system by stepping up the voltage produced by the generator to match the higher voltage levels of the transmission grid. Accurate and timely information regarding these transformers is vital for the Transmission Operator to effectively manage and coordinate the operation of the transmission system, ensure system reliability, and perform necessary planning and operational functions.

The Generator Owner must also provide technical details, such as transformer ratings, impedances, and operational limits, which help the Transmission Operator in their efforts to assess the system's performance and stability. Thus, the Generator Owner's role in this context is pivotal to maintaining seamless communication between generation and transmission systems for operational efficiency and reliability.
