Shanghai takes more steps to ensure summer power supply

Shanghai has wrapped up a series of grid enhancements and secured green electricity from north China to brace for peak summer demand.  

On June 30, the 110kV Chongming Changjiang Substation Renovation Project began operations in Shanghai, marking the completion of all 55 major grid enhancement projects for this year's summer season. 

These infrastructure upgrades include 114 kilometers of new 220kV+ transmission lines and 1.68 million kVA of additional transformer capacity, significantly strengthening the city's power distribution network.

In a strategic energy move this spring, State Grid Shanghai secured 202 million kilowatt-hours of renewable electricity through green power transactions with Jilin, Heilongjiang and Inner Mongolia, covering the critical May-December period including the summer demand peak.

This innovative market approach simultaneously supports renewable energy utilization in northern regions while meeting Shanghai's clean power needs.

To bolster stability, State Grid Shanghai secured annual power purchase agreements and coordinated with the Southern Power Grid for added evening capacity. It has also optimized green power transactions to supplement supply, while implementing detailed load forecasting to balance reliability, affordability, and sustainability.

These integrated measures aim to strengthen the city's power resilience and meet growing demand during the peak summer period.
