Following a surge in solar and wind power installations last year, multiple regions across China are experiencing difficulties managing fluctuations in electricity supply linked to weather conditions.
Energy and grid officials emphasized during a panel discussion at the Boao Forum for Asia in Hainan, China, on Tuesday, the imperative to continue investing in new power infrastructure and enhancing policies and market regulations to prevent these strains from impeding the energy transition.
“Everyone advocates low-carbon transformation,” said Qian Chaoyang, president of China Southern Power Grid. “We also need to vigorously promote the interconnection of power grid infrastructure.”

The condition of China’s grid has emerged as a pivotal aspect in the battle against climate change. President Xi Jinping has underscored the nation’s commitment to maintaining its unprecedented pace of renewable installations.
Consequently, grid operators must devise strategies for efficiently transporting electrons across various timeframes and geographical locations.
One potential remedy involves expanding energy storage capabilities. Last year, China saw its battery storage capacity almost quadruple.
Moreover, Qian advocated for increased financial backing for pumped hydro systems, which leverage water and gravity to store surplus energy for future use.

Liu Zhenya, former chairman of State Grid Corp. of China, proposed that the country prioritize the development of a more extensive transmission network between the northwest—abundant in both coal and renewable energy resources—and the southwest, which heavily relies on hydropower and faced electricity shortages during a drought in 2022.
This approach, he argued, would obviate the necessity for constructing energy storage facilities in the northwest and additional power plants in the southwest, resulting in significant investment savings of billions of yuan.
