Guizhou, Hunan, and Chongqing have established a new cross-regional power-sharing mechanism, marking a milestone in flexible grid coordination. According to China Southern Power Grid, the Qiandong and Erlang power plants in Guizhou have successfully begun supplying electricity not only to the local grid but also to neighboring provinces. Qiandong can now deliver power to both Guizhou and Hunan, while Erlang serves Guizhou and Chongqing. The move strengthens grid flexibility and improves emergency response during peak demand periods, laying a stronger foundation for regional energy security.
With abundant hydropower and coal reserves, Guizhou has also emerged as a major hub for renewable energy growth. It is one of the key suppliers in China’s West-to-East power transmission initiative, exporting more than 45 billion kWh of electricity annually—a win-win setup for eastern and western regions alike.
Power demand across Guizhou, Hunan, and Chongqing varies significantly by season. “For Guizhou, winter brings peak electricity demand, but also challenges such as dry-season water shortages and extreme weather conditions like ice and snow,” said He Hongyan, General Manager of Strategic Planning at Guizhou Power Grid Co.
“The newly built interconnection lines between Guizhou and its neighbors allow for more dynamic power balancing,” she added. “This helps bridge seasonal supply-demand gaps and improves the region’s ability to respond quickly to energy needs.” During this year’s winter peak, the combined maximum output from Qiandong and Erlang is expected to reach 2.52 GW.
