Jiangsu Province in China has completed a series of major power grid upgrades to meet the increasing electricity demand during the 2024 winter peak.

Chen Songtao, head of the Planning Division at State Grid Jiangsu Electric Power Co Ltd, highlighted that these upgrades have significantly enhanced the province’s grid structure. The improvements are designed to accommodate the growing demand for large-scale grid connections for new energy sources in northern Jiangsu while strengthening the power supply in the southern part of the province.

The Shangdang substation project, initiated in May, increased the capacity of its main transformer from 750 to 1,000 megavolt-amperes. This expansion is expected to meet the electricity needs of 3.3 million households, ensuring a stable power supply for Zhenjiang during the winter months.

Jiangsu’s electricity consumption has seen substantial growth. From January to November, the province’s social electricity consumption reached 773.949 billion kilowatt-hours (kWh), an 8.99% increase compared to the previous year. Zhenjiang alone saw a 7.58% increase, consuming 29.838 billion kWh.

Another significant project completed this year was the 500-kV Haiyang Transmission and Transformation project in Taizhou. This substation, part of Jiangsu Power Grid’s “4th Five-year Plan”, will provide reliable electricity for approximately 4.38 million households annually.

These upgrades are crucial for maintaining a safe and reliable electricity supply for both enterprises and residents in Jiangsu during the winter peak demand period. The State Grid Jiangsu Electric Power Co Ltd has implemented intensive control over project timelines and refined its management to ensure these critical infrastructure improvements were operational before the peak of winter electricity demand.

These developments demonstrate Jiangsu’s proactive approach to meeting growing energy needs and integrating new energy sources into its power grid, ensuring a stable and efficient electricity supply for the region’s continued economic growth and residential comfort.
