As winter heating demand peaks, CECEP’s renewable energy subsidiaries are resolutely fulfilling their responsibility to ensure energy security. Leveraging intelligent operation and maintenance technologies alongside advanced management systems, they are advancing on multiple fronts in close coordination to safeguard the safe and stable supply of electricity. Through this commitment to keeping homes warm, CECEP demonstrates the mission and responsibility of a central state-owned enterprise. During the current heating season, the Group is expected to deliver more than 6 billion kilowatt-hours of green electricity.
Amid severe winter challenges such as cold waves, rain and snow, CECEP Solar and CECWPC have established dedicated drone inspection teams. Large-scale deployment of drones equipped with infrared thermal imaging and AI algorithms enables routine inspections that act like aerial vanguards, rapidly and accurately identifying hidden risks in key components and transmission lines at power stations and wind farms. This has helped build a new inspection system that is safer, more efficient and more precise, shifting operations from reactive repairs to proactive prevention. As a result, fault identification accuracy has risen to over 90 percent, and inspection efficiency has increased by about 180 percent compared with manual methods.
To ensure stable operations, power stations and wind farms strictly enforce duty rosters for critical positions, strengthen technical contingency plans and equipment management, and remain steadfast on the front lines despite harsh winter conditions. CECEP Solar operations in the northwest and central-west regions have intensified anti-freezing inspections and parameter monitoring for key equipment during extreme cold, while facilities in eastern China use water-surface cleaning robots to improve module cleaning efficiency. Wind farms have enhanced equipment reliability and grid support capacity under extreme weather through icing monitoring and early warnings, optimized operating strategies and emergency material reserves, ensuring turbines run steadily, generate reliably and respond effectively when needed.
During the year-end critical period, CECEP is also maximizing the role of its commissioned energy storage facilities as system “regulators” to smooth power output fluctuations. Several key projects have achieved breakthroughs, including CECEP’s largest independent energy storage project to date—the 200 MW/800 MWh Luzimiao facility in Inner Mongolia—which has successfully completed reverse power transmission and entered the commissioning phase. The 100 MW/400 MWh independent energy storage project in Dabancheng, Xinjiang, is also undergoing intensive installation and commissioning and will soon be connected to the grid. Once operational, these projects will significantly enhance local grid peak-shaving capacity and renewable energy integration, providing vital flexibility for winter power supply.
While ensuring electricity supply, CECEP’s frontline employees braving severe cold and working day and night have themselves become a warm sight in winter. During a return trip after completing maintenance work, operations staff at Tuoli Wind Farm in Xinjiang successfully rescued two private vehicles trapped in deep snow, battling force-11 winds and extremely low visibility for more than two hours to bring the drivers to safety, exemplifying CECEP employees’ strong sense of responsibility. In Inner Mongolia, staff at Yongxing and Dengjialiang wind farms and Taihe New City heating station remain focused on meeting the heating needs of 3,500 households. Using an intelligent heating platform for precise load forecasting and dynamic regulation, they ensure end users receive stable and comfortable heating services. From the snowy Tianshan Mountains to the Gobi Desert, and from the North China Plain to the southern hills, sunlight and cold winds alike are being transformed through refined management and technological innovation into green energy that keeps millions of homes lit and warm. With a strong sense of duty and unwavering dedication, CECEP employees continue to stand on the front lines of energy supply, caring for household warmth and public safety, and contributing solidly to steady economic and social operations and the green transformation of energy.
