en.Wedoany.com Reported - Unit 1 of the China Coal Lu'an Power Plant's 2×660 MW ultra-supercritical double-reheat coal-fired generating units, constructed by Anhui Electric Power Construction No. 2 Company of China Energy Engineering Group, recently passed its 168-hour full-load trial run and officially entered commercial operation. Located in Lu'an, Anhui Province, the unit adopts ultra-supercritical double-reheat technology, achieving a thermal efficiency exceeding 48%, a net coal consumption rate as low as 254.4 g/kWh, and an annual power generation capacity of approximately 6.3 billion kWh.
During the construction of Unit 1 of the China Coal Lu'an Power Plant, the project team collaborated deeply with the owner, supervisor, and design institute, breaking conventional construction sequences to simultaneously commence foundation and main structure work, and advancing civil engineering and installation in parallel. Eleven out of thirteen milestone nodes were completed ahead of schedule. Precision control in turbine installation was a key aspect: the 66-ton generator rotor was precisely positioned in a single 40-minute operation using an electric traction system, and the 300-ton stator was smoothly hoisted using a dual-overhead crane combined lifting method. During boiler construction, none of the 57,118 pressure-bearing weld joints leaked under the 40.57 MPa ultra-high-pressure hydrostatic test. Welding team leader Xin Yanlin showed his arm scarred by welding sparks, while Project General Manager Tao Yukui emphasized that millimeter-level precision comes from concentration.
The project department implemented a model of factory-based construction, digital management and control, and permanent-temporary integration. Circulating water pipes and steel structures were prefabricated in factories and then assembled on-site. The steel structure of the coal transport bridge in the coal bunker bay was hoisted piece by piece, saving over 200,000 yuan in external machinery rental costs. Electrical equipment achieved 100% factory pre-assembly and modular lifting. Meanwhile, a digital infrastructure MIS system was established, utilizing QR code grid management for progress, safety, quality, and cost, and introducing virtual commissioning technology to pre-verify interlock protection logic, shortening the commissioning period—66 switchgear cabinets were commissioned in 15 days, and the electrical back-feed was successful on the first attempt. Technical lead Liu Xiaoyu stated that virtual commissioning enabled "making corrections before execution." Formal roads, pipelines, and floor slabs were constructed simultaneously, and the electrostatic precipitator foundation was combined with the tower crane foundation, reducing temporary facility investment and advancing project handover for safety by 2.5 months. Party Branch Secretary Shi Xiuwen pointed out that the power plant's construction concerns the future of the old revolutionary base area.
The commissioning of Unit 1 of the China Coal Lu'an Power Plant provides power support for the western Anhui region, while also serving as a practical case for the transition of traditional coal-fired power towards clean and high-efficiency models, reflecting the synergy between energy security and low-carbon development under the coal-power joint operation model. The project construction team is from Anhui Electric Power Construction No. 2 Company of China Energy Engineering Group, and the project is located in Lu'an City, an old revolutionary base area in the Dabie Mountains.
