Shares of Chinese electricity and grid equipment makers surged after State Grid unveiled a 4 trillion yuan (US$574 billion) plan to upgrade the country’s power networks, as surging demand and the global race in artificial intelligence drive investment in energy infrastructure.

Transformer makers Sieyuan Electric and Shanghai Guangdian Electric triggered the trading halt mechanism after surging 10 per cent on Friday morning. At least 11 mainland-listed companies rose 10 per cent or more in the morning before retreating in the afternoon. That bucked a decline in the CSI 300 Index, which slipped 0.41 per cent.

State Grid, the largest utility in China and the world, announced on Thursday that it would ramp up investment in infrastructure over the next five years through 2030, marking a 40 per cent increase from the preceding five-year period and a record investment for the state-backed giant.

The funds would be used to build a “new type of power system”, with targets including adding 200 million kilowatts of renewable energy capacity annually and increasing the share of non-fossil consumption to 25 per cent by 2030, State Grid said. The company oversees electricity usage of 1.1 billion people across 88 per cent of China’s territory.

Main investments would be made in China’s western regions, where there was a surplus of power supply but a shortage of grids that could transmit the energy, according to Huatai Securities.

“The investment in non-ultra high voltage grids is expected to accelerate,” said Liu Jun, an analyst at the brokerage. “It’s clear that the weak power grids in the western region need to be upgraded against the backdrop of building a unified national power market.”
