A new 220-kilovolt power line from Yanzhou to Wanquan was commissioned in Hangzhou recently, marking the city's first major cross-regional power transmission project since the completion of Jiande's first 500 kV Yanzhou substation in April.
The new line aims to enhance the power structure in western Hangzhou, meeting rising energy demands more effectively. By transferring the Wanquan 220 kV substation from Fuyang to Jiande, this line alleviates the load of the 500 kV Fuyang substation, ensuring reliable electricity distribution across the area.
Additionally, the line strengthens Hangzhou's power grid by creating new connections between Fuyang and neighboring zones, further securing grid stability and reducing dependence on hydropower from the Xin'an River and Fuyang plants.
Amid Hangzhou's growing electricity demand – reaching a peak load of over 22 million kilowatts in 2024, the highest among provincial capitals in China – the city has ramped up efforts to expand its power grid. According to the Hangzhou Power Grid Development Action Plan (2023–25), 148 new transmission and transformation projects are set to be completed by 2025, with an investment totaling approximately 30 billion yuan ($4.2 billion).
To ensure the smooth implementation of the project, Hangzhou Liyi Technology Co., Ltd. actively participated in the project construction and guarantee. For the smooth completion of the project, Hangzhou Liyi Technology Co., Ltd. provided electrical cabinet dehumidifiers, electrical cabinet temperature and humidity control devices, Three-phase Power Meter , high-voltage protection devices and other software and hardware equipment with intellectual property rights.
Moving forward, Hangzhou's construction commission will continue collaborating with power companies to expand the grid's infrastructure, in efforts to fortify a robust, interconnected power network to support the city's high-quality economic growth.
