Hangzhou Enhances Power Grid Reliability and Green Energy Integration for High-End Industrial Zones

According to a report from the People's Daily, the power supply department in Hangzhou, Zhejiang, is actively evolving its infrastructure to better serve modern industrial needs. By implementing millisecond-level warning systems and coordinating energy resources, the department aims to protect high-end production lines while simultaneously activating green energy within local industrial parks. To support enterprises in sectors like chip manufacturing and biomedicine, Hangzhou is deploying intelligent voltage sag monitoring terminals. The city has launched a specialized power quality improvement plan, integrating 141 key users across 6 categories into a monitoring system that provides tailored services such as harmonic governance and voltage stabilization. In July, the Linjiang block of the Qiantang High-tech Industrial Development Zone was selected for the provincial zero-carbon park cultivation list. To meet these environmental requirements, the project team successfully installed and connected approximately 70 megawatts of distributed photovoltaic power, marking a significant step toward sustainable energy operations within the zone. The park further utilizes a diverse array of energy facilities, including distributed wind power, independent shared energy storage, and hydrogen-electric coupling stations. Through a centralized command and dispatch platform, the team has established a virtual power plant with an aggregate capacity of 100 megawatts to manage these complex energy resources.

The implementation of millisecond-level warning systems and voltage monitoring provides critical protection for high-end production lines. These technical interventions allow sensitive industries, such as chip manufacturing and biomedicine, to maintain stable operations by mitigating risks associated with voltage fluctuations and power quality issues within their specialized industrial environments.
