New safety rules for on-site metering to bolster grid security

Shaoxing in East China's Zhejiang province has introduced updated safety measures for installing smart meters and electric vehicle charging stations, strengthening operational safety protocols for field personnel.

The newly released Safety Measures for On-Site Metering Operations provide frontline workers with detailed guidance and standardized procedures to better identify and mitigate risks during metering and charging infrastructure operations.

The update is part of ongoing efforts by State Grid Shaoxing Power Supply Company to enhance safety management systems and reduce hazards associated with the growing integration of renewable energy and EV technologies into the grid.

This revision applies to all on-site metering operations across Shaoxing and focuses on improving safety measures and controlling backfeed risks in scenarios such as charging and swapping facilities, photovoltaic equipment access, concentrator modifications, high-voltage live secondary warehouse operations, and low-voltage meter testing and commissioning.

A whitelist mechanism has also been introduced for low-risk metering operations, enabling differentiated management for high-frequency, controllable-risk operations, such as on-site calibration of low-voltage energy meters and data collection and maintenance.

This approach ensures safety while optimizing personnel arrangements and workflow, improving both safety management and operational efficiency.

State Grid Shaoxing Power Supply Company said it will maintain high standards and strict requirements, strengthen safety training and on-site supervision, and fully implement the new regulations to improve the safety of on-site operations.
