Investments in key energy projects surge in 2025

China's investment in key energy projects surged to a record 3.5 trillion yuan ($505 billion) in 2025, as the world's largest energy consumer immensely expanded its renewable capacity while reinforcing domestic energy security, according to authorities.

The nearly 11 percent year-on-year growth in energy spending significantly outpaced other sectors of the Chinese economy, according to the National Energy Administration.

The growth rate for energy investment was 12.9 percentage points higher than that of national infrastructure and 10.1 percentage points higher than that of the manufacturing sector over the same period, figures released by the administration show.

Xing Yiteng, deputy director of the NEA's development planning department, said the investment surge highlights the energy sector's role as a primary engine of China's industrial upgrading and economic stability.

The 2025 data underscore Beijing's commitment to its dual carbon goals — peaking carbon emissions before 2030 and achieving carbon neutrality before 2060.

"Investment in new energy formats is being released at an accelerated pace," Xing said. He noted that emerging sectors, specifically new-type energy storage and hydrogen energy, saw investment figures double compared to the previous year, as China seeks to solve the intermittency issues associated with its massive renewable fleet.

Cumulative renewable capacity has currently surpassed 1.8 billion kilowatts. Renewable generation reached approximately 4 trillion kilowatt-hours — surpassing the total electricity demand of the 27 EU member states, which stands at roughly 3.8 trillion kWh, he said.

A significant portion of China's renewable energy growth was driven by onshore wind projects, where investment in key developments jumped nearly 50 percent year-on-year.

The energy storage sector also saw explosive growth, with new energy storage capacity surging 84 percent compared to the end of 2024. By the end of 2025, China's operational energy storage capacity had reached 136 million kW, a more than 40-fold increase since 2020, according to the NEA.

In a shift that highlights the increasing role of private actors in China's energy landscape, private sector investment outpaced the national average. Investment by private firms in key energy projects grew by 12.9 percent year-on-year, roughly 2 percentage points higher than the overall industry growth rate. Private capital has remained particularly active in solar power, wind power and coal mining.

The robust participation of private capital is crucial for the "distributed" energy model Beijing is promoting, which places solar panels on rooftops and smaller-scale wind farms closer to demand centers, said Lin Boqiang, head of the China Institute for Studies in Energy Policy at Xiamen University.

Despite the rapid shift toward renewables, the NEA emphasized that traditional energy security remains a top priority. Investment in coal-fired power and conventional hydropower remained steady to ensure a stable baseload for the national grid.

Large-scale hydropower clusters in China's southwest river basins are being fast-tracked. Simultaneously, the country is pouring capital into its ultra-high voltage power grid.

These cross-regional transmission lines are essential for moving clean electricity from the wind and solar hubs in the remote west to the power-hungry industrial hubs in the east.

The NEA report highlighted five regions and provinces — the Inner Mongolia autonomous region, the Xinjiang Uygur autonomous region, as well as Shandong, Guangdong and Jiangsu provinces — as the primary drivers of this spending, with each surpassing 200 billion yuan in annual energy investment.

The briefing comes as China manages its winter peak demand period. The NEA noted that the record investment in 2025 has provided a critical buffer, ensuring that power supplies remain stable despite high seasonal heating demands.

The NEA expects the momentum to continue in 2026, particularly as the integration of artificial intelligence with the energy sector and smart grids begins to attract more capital.

The 3.5 trillion yuan milestone marks a turning point for China, indicating that the nation is no longer transitioning at the margins but is fundamentally retooling its entire economic infrastructure around a low-carbon, high-security energy model, the NEA said.
