State Grid unveils record 4 trillion yuan plan to modernize power network

State Grid Corporation of China announced plans to invest about 4 trillion yuan (roughly $574 billion) between 2026 and 2030 to upgrade and expand the national power grid, a roughly 40 percent increase in five‑year fixed‑asset investment versus the 2021–2025 period. The programme, the largest five‑year capital plan in the company’s history, is aimed at easing transmission bottlenecks, integrating surging renewable generation and bolstering reliability as electricity demand accelerates.

The operator controls roughly 88 percent of China’s territory and oversees electricity for about 1.1 billion people, making the scale of the planned spending consequential for the country’s energy transition and industrial policy. State Grid said the funds will prioritise ultra-high-voltage transmission and long-distance lines that can carry surplus wind and solar output from resource-rich western provinces to dense industrial and urban centres in the east.

Key numerical targets in the plan include a reported goal to add about 200 million kilowatts of renewable energy capacity annually and to lift the share of non‑fossil energy consumption to about 25 percent by 2030. The investment package is intended to support those targets by expanding long-distance transmission capacity and upgrading system flexibility and resilience.

The spending push reflects mounting demand pressures. Rapid expansion of wind and solar generation has repeatedly run into curtailment because lines and regional grids have not kept pace. At the same time, faster adoption of electric vehicles and the growth of data centres and AI computing facilities are driving higher, more variable power needs across major load centres. Complementary national objectives call for a sharp increase in grid-scale battery storage capacity, with targets to more than double storage to around 180 gigawatts by 2027 and to attract roughly 250 billion yuan of related investment.

The plan is also part of a broader rise in transmission and grid investment. Industry estimates show spending on ultra-high-voltage projects has been climbing at double-digit rates since 2022, reinforcing the centrality of long-distance lines in China’s strategy for moving renewable power at scale. State Grid and its peer, China Southern Power Grid, have both been stepping up capital allocations; combined spending by the two operators had been projected to reach about 825 billion yuan in 2025.

Markets reacted positively in equipment and construction sectors tied to grid build-out. Shares of several electricity and grid-equipment makers posted notable gains following the plan’s release, even as the broader CSI 300 index edged down. The surge underscores investor expectations that suppliers and state contractors will capture a substantial share of the procurement pipeline.

Implementation will determine the long-term impact. If carried out as planned, the 4 trillion yuan programme could materially reduce renewable curtailment, enable deeper penetration of wind and solar, and underpin faster electrification of transport and industry. It will also test financing channels and project execution capacity at a scale that will shape China’s near-term emissions trajectory and the competitiveness of domestic grid technology suppliers.
