State Grid Xuzhou Power Supply Company: Digital tools revitalise aging communities

State Grid Xuzhou Power Supply Company has successfully deployed digital governance technology in a neighborhood renewal project, resolving long-standing wiring issues in older residential areas. The initiative marks the first time that low-voltage data-quality tools have been applied to old-community upgrades in the city.

The project focused on the 10 kV Peitou line's No. 1 box transformer at Xinxinda Garden, which supplies power to two 1980s-era residential compounds—former staff housing for a printing factory and the local ICBC branch. Over decades, piecemeal line extensions had left feeder-to-customer and phase-to-customer records riddled with errors, complicating renovation work.

To overcome these challenges, the utility adopted a hybrid model combining digital analysis with on-site inspections. Using an AI-driven service command platform, advanced cable-detection tools, and a similarity-matrix algorithm, engineers reduced anomaly detection time from 30 minutes to just 5—a nearly 80% improvement in efficiency.

The cleanup achieved 100% accuracy in mapping feeder-to-home and phase-to-home connections. This accurate digital ledger will underpin future cable replacements, enable precise outage notifications, speed up generator integration, and support seamless switching of power facilities—enhancing both the quality of infrastructure upgrades and the everyday electricity experience of residents.
