China's first 220-kV smart energy station—Zhuzhou Chengjia (Baiguan) 220-kV Smart Energy Station—has begun operations.

China's first 220-kV smart energy station—the Zhuzhou Chengjia (Baiguan) 220-kV Smart Energy Station—officially began operations on August 31, 2022. Built upon the foundation of a conventional substation, it integrates a data center, AC/DC microgrid, charging station, photovoltaic power station, and 5G communication base station, creating an integrated operational platform that seamlessly combines "energy flow, data flow, and business flow."

The Zhuzhou Chengjia Smart Energy Station is a comprehensive energy hub integrating the five key areas of "construction, equipment, control, information, and operations." The substation can gradually provide up to 960,000 kVA of transformer capacity, ensuring a robust power supply for the surrounding industrial parks.

The Zhuzhou Chengjia (Baiguan) 220-kV Smart Energy Station is a major science and technology demonstration project undertaken by State Grid Corporation of China to implement the nation’s “Dual Carbon” strategy, fulfill the responsibilities of a central enterprise, accelerate the development of a new-type power system, and drive the clean, low-carbon transformation of energy. It also represents State Grid Corporation of China’s innovative exploration and practical efforts in resource conservation, environmental friendliness, and the integrated construction of "multi-station convergence."

Shanghai OUMIAO provides comprehensive online monitoring services for the 220 kV smart energy station GIS, transformers, and switchgear at Zhuzhou Chengjia (Baiguan). Products include: an online GIS partial discharge monitoring system, an arrester online monitoring system, an SF6 gas density digital remote transmission monitoring system, a wireless temperature monitoring system for switchgear, and an online transformer oil chromatography monitoring system, among others.

Once the project is completed and put into operation, it will effectively ensure the comprehensive energy supply and secure power operation in the Zhuzhou area, while significantly easing the summer peak-load pressure on the grid in Zhuzhou’s Hedong urban district and enhancing the reliability of Zhuzhou’s power supply network.
