China's west-to-east power transmission project has delivered more than 1 trillion kilowatt-hours of clean electricity to east China's Jiangsu Province, providing strong support for energy security and low-carbon transition in the Yangtze River Delta, according to data released by State Grid Jiangsu Electric Power Company.

The cumulative volume has reached 1.08 trillion kWh, enough to meet the annual electricity demand of approximately 360 million households.
The west-to-east power transmission project, a key national strategy designed to channel surplus electricity resources from western regions to energy-intensive eastern areas, is increasingly shifting toward clean energy as China advances its carbon reduction goals.
Clean energy now accounts for more than 50% of the electricity transmitted to Jiangsu, supporting carbon emission reductions of over 460 million tonnes. The system's maximum daily transmission capacity has reached 31.5 million kilowatts, meeting nearly a quarter of the province's electricity demand.
At a policy briefing on March 7, National Development and Reform Commission official Chen Lei said that during the 15th Five-Year Plan (2026-2030) period, the country's west-to-east power transmission capacity is expected to exceed 420 million kilowatts, further strengthening nationwide energy allocation and green development.
