State Grid Jiaxing enhances services for high-tech businesses

Reliable power supply is essential to industrial development, while high-quality electricity services help improve the business environment and boost corporate efficiency. Jiaxing in Zhejiang province, located in the Yangtze River Delta region, is seeing a growing concentration of businesses engaged in new quality productive forces.

Since the beginning of this year, State Grid Jiaxing Power Supply Co (State Grid Jiaxing) has stepped up tailored services for businesses with sensitive electrical loads, adopting a customized approach to addressing power quality issues and supporting innovation-driven development.

On Sept 11, staff members from the company visited Hana Microelectronics (Jiaxing) Co to conduct a targeted inspection of the company's sensitive electrical loads. They helped identify critical equipment and develop measures to improve power quality, providing tailored support for the high-tech enterprise.

Hana Microelectronics is a high-tech company specializing in semiconductor packaging, microelectronics assembly, and the production and sales of related optoelectronic and electromechanical products. Equipment used in key processes such as packaging and testing is highly sensitive to voltage sags, which are short-term drops in voltage that can disrupt production.

"In the past, our customized services focused more on ensuring the reliability of power supply. Now, we are working to strengthen users' ability to protect sensitive equipment against the effects of voltage fluctuations," said Wei Bo, an employee of State Grid Jiaxing.

During the visit, employees followed requirements set out in a notice issued by the Zhejiang Office of the National Energy Administration on improving power quality services to support the development of new quality productive forces. They reviewed each company's key production processes, critical equipment and load characteristics, identified equipment sensitive to voltage sags, and established dedicated service records for each enterprise.

The team also conducted a comprehensive inspection of the company's power supply protection system, focusing on the operating status and backup duration of uninterruptible power supply systems serving critical production equipment. The inspection confirmed that the existing power supply systems were operating normally and had sufficient capacity to support current critical loads.

In addition, staff members explained the causes of voltage sags and measures to prevent and mitigate their effects. They also introduced methods for identifying sensitive loads and outlined routine maintenance precautions to help the company improve its power quality management.

Tong Jun, the company's electrical manager, said the professional guidance provided a clearer understanding of voltage sag prevention and offered useful reference for strengthening protection across production lines.

Since the beginning of this year, State Grid Jiaxing Power Supply Company has implemented a special initiative to improve the power supply quality in line with requirements from its headquarters. Taking into account Jiaxing's role as a key node in the Yangtze River Delta computing power network and the town’s status as a hub for emerging industries, the company has continued to expand its customized services, shifting from a reactive response model toward more proactive support.

The company said it will continue to identify sensitive users and critical electrical loads across its service area, regularly update its dedicated service records, and establish a closed-loop mechanism covering inspection, assessment, recommendations and follow-up.
