China’s long-running effort to build out its energy sources is getting fresh momentum from the war in the Middle East, reinforcing a strategy that’s sent grid operators on a bond-selling binge and funneled hundreds of billions of dollars into the market.
“China’s infrastructure build out is far more efficient than that of most countries, and the power grid is no exception,” said Penny Chen, a senior director with Fitch Ratings. As surging power prices become a binding constraint on AI and manufacturing ambitions elsewhere, that advantage is set to widen.
State Grid operates power lines covering more than 80% of the country, delivering electricity to more than 1 billion people. Southern Grid handles most of the rest of the nation, including the economic powerhouse Guangdong.
State Grid did not immediately respond to a request seeking comment.
The rush to fund power infrastructure has allowed State Grid, the world’s largest utility firm, to regain the title as the country’s largest bond issuer since 2024, overtaking major commercial banks and the state railway builder. The firm issued a record 754.5 billion yuan of bonds domestically last year alone, almost tripling the previous year’s total, after its capital spending increased by 20% a year earlier.
State Grid’s average annual bond issuance could be around 1.2 to 1.4 trillion yuan over the next five years, according to Li Gen, founder of Beijing G Capital Private Fund Management Center. During peak construction this year and next, annual issuance could even exceed 1.5 trillion yuan, which “firmly cements its position as China’s largest corporate bond issuer” and even surpassing total issuance of many provinces.
But cheap and plentiful electricity requires more than just heavy spending. China’s transmission and battery-storage assets are underutilized, and the path to market reforms that would unlock them remains unclear. Questions are also mounting over how state grids will pay back record debt loads, especially if efficiency fails to improve.
Still, the recent disruptions in the Strait of Hormuz underscore the logic behind China’s strategy. “These incidents highlight the importance of localizing energy sources to ensure security and stability,” said Lin Boqiang, director of the China Institute for Studies in Energy Policy at Xiamen University. China’s shift toward green energy is the right strategic move, he added.
