China is stepping up investment in its electricity networks as part of a long-term strategy to strengthen energy security and reduce reliance on imported fuels. Recent tensions in the Middle East have added momentum to the country’s grid expansion plans, pushing state-owned operators to raise record levels of financing.

China has become one of the world’s largest investors in power grid infrastructure, spending heavily to integrate growing volumes of renewable energy and move electricity from remote western regions to industrial centres in the east. The expansion has turned state grid companies into the country’s largest bond issuers.

So far this year, the two main operators – State Grid Corp. of China and China Southern Power Grid Co. – have issued $13.5 B (92.5 billion yuan) in domestic bonds. This follows a record $131.4 B (901 billion yuan) raised in 2025, with average yields around 1.7 %, the lowest on record.

State Grid operates transmission lines covering more than 80 % of China and supplies electricity to over 1 billion people, while China Southern Power Grid serves the remaining regions, including the major economic hub of Guangdong.

The country plans to invest about $729.9 B (5 trillion yuan) in electricity networks over the next five years. Much of the funding will support construction of a large interconnected grid capable of transporting renewable power more efficiently.

State Grid alone issued a record $110.1 B (754.5 billion yuan) in bonds last year, nearly three times more than the previous year. Analysts expect annual bond issuance to reach between $175.2 B (1.2 trillion) and $204.4 B (1.4 trillion yuan) in the coming years as construction accelerates.

Experts say the strategy reflects China’s growing focus on energy independence, particularly as global supply disruptions highlight the risks of relying heavily on imported oil and gas.
