Duke Energy
The Duke Energy Kennel Substation project was undertaken to significantly enhance reliability and introduce new circuits to support another station. Commonwealth played a crucial role in assisting Duke Energy with the intricate protection and control design. This design was tailored for a greenfield station and featured a new six-breaker 69kV ring bus with four-line positions, a spare bus, and a distribution transformer equipped with two feeder circuits. Additionally, the design incorporated a 24’ x 55’ control building, which housed the station battery system, relays and controls, and SCADA equipment. This control building was meticulously sized to accommodate a future ultimate station configuration, which would expand the ring bus to include ten 69kV breakers and three distribution transformers.
The control building was strategically designed for future scalability, ensuring it could support an expanded ring bus with ten 69kV breakers and three distribution transformers. Updates were also implemented to modify the remote end station’s line numbers and replace the line relaying, ensuring seamless coordination with the line relays at the new Kennel Substation. The comprehensive design was successfully completed in 2023 and the substation became operational in the first quarter of 2024.
This project not only underscores Duke Energy's commitment to enhancing infrastructure reliability but also highlights the collaborative efforts with Commonwealth in achieving a robust and future-proof substation design.
