China Power Construction Shifts Focus to Grid Upgrades as Wind and Solar Expand

China's power construction sector is shifting capital toward grid stability, direct-current corridors, and flexible capacity as renewable energy scales rapidly, according to an industry annual report released by the China Electric Power Construction Association. By the end of 2025, combined wind and solar capacity reached 1.84 billion kilowatts—accounting for 47.3 percent of the country's total power generation capacity and surpassing coal for the first time. The sector is recalibrating investments to balance decarbonization goals with baseline power reliability.

The milestone of wind and solar capacity surpassing thermal generation reflects a structural transition in China's energy mix. However, the surge in intermittent renewables creates significant integration challenges, shifting investment priorities from raw capacity expansion to transmission corridors, intelligent microgrids, and flexible balancing resources.

China's power construction industry is adjusting its medium- and long-term trajectory toward high-quality infrastructure upgrades, with spending concentrating heavily on direct-current transmission corridors, storage, and intelligent distribution, according to the China Electric Power Construction Association's annual report released in August 2026. The sector reached a structural milestone at the end of 2025, when total nationwide installed generation capacity reached 3.9 billion kilowatts, an increase of 16.2 percent year-on-year. Of that total, combined wind and solar installations climbed to 1.84 billion kilowatts, representing 47.3 percent of overall capacity and exceeding coal-fired power capacity for the first time. Wind and solar also accounted for nearly 80 percent of the 550 million kilowatts in new capacity brought online in 2025. In response to the massive expansion of intermittent generation, overall capital allocation in power construction has evolved. Major domestic power companies invested 1.7323 trillion yuan across projects in 2025. While spending on wind, solar, and conventional hydropower tapered, investments in coal and nuclear power maintained positive growth to ensure baseload stability and dispatchable flexibility. Simultaneously, infrastructure investment shifted toward grid networks. Power grid engineering investments reached 639.5 billion yuan in 2025, up 5.1 percent year-on-year, with spending on direct-current grid projects surging by 25.7 percent. According to the association, priorities during the upcoming 15th Five-Year Plan period (2026–2030) include advancing ultra-high-voltage transmission channels, upgrading urban and rural distribution grids, and accelerating pilot projects for smart microgrids and virtual power plants. Technological deployments across the industry have accompanied the investment shift. Recent developments include 20-megawatt offshore wind turbines, carbon fiber blades, ultra-supercritical circulating fluidized bed boilers, ultra-high-voltage circuit breakers, and commercial carbon capture, utilization, and storage projects. Additionally, Chinese engineering contractors expanded their overseas footprint, with power project contracts and equipment exports active across 68 countries and regions.
