At 15:17 on December 22, 2025, the final blade was precisely connected to the nacelle hub, marking the successful completion of the last wind turbine installation using the Jinli luffing tower crane. Simultaneously, the 220-kilovolt substation achieved successful reverse energization in one attempt. This milestone signifies a critical breakthrough in the project, officially establishing the key "power transmission" pathway and ushering the project into the final phase of system commissioning and grid connection. These achievements lay a solid foundation for realizing full-capacity grid integration.

    The project is located in Xinxing District and Boli County of Qitaihe City, Heilongjiang Province. As a key initiative to promote energy structure optimization and support green, low-carbon transformation, it has a total installed capacity of 312.5 megawatts, comprising 50 hybrid-tower wind turbines each with a capacity of 6.25 MW (hub height at 160 meters). It also includes the construction of a 220-kilovolt booster substation and a collector power line system.

    During construction, the project team confronted multiple challenges including complex terrain, extreme weather conditions, and the transportation of oversized components. Through scientific evaluation of lifting plans, optimized construction scheduling, enhanced meteorological monitoring, and round-the-clock site management, the team efficiently completed the installation of all wind turbines.

    To date, eight turbine units have already completed grid connection testing, while the remaining units are progressing steadily with electrical installation and system commissioning.

    This reverse energization process served as a comprehensive test of the installation quality of equipment and the effectiveness of system commissioning at the booster substation. With close coordination between equipment manufacturers and installation and commissioning teams, all equipment operated stably and monitoring data remained within normal ranges, successfully enabling power from the external grid to be smoothly fed back into the substation. This achievement provides stable voltage support for subsequent wind turbine power generation and grid connection, demonstrating the high level of management expertise and technical capability inherent in modern renewable energy projects.

    Harnessing the wind of innovation and riding the momentum of the times, the project team is taking concrete actions to respond to the nation’s “dual carbon” strategy. Committed to advancing green and low-carbon development, the team will seize the successful completion of the substation reverse energization and turbine installation as a key opportunity. Upholding quality as the fundamental principle, they will fully advance subsequent grid connection commissioning, trial operations, and full-capacity commissioning efforts. The team strives to achieve comprehensive project operation at the earliest possible date, injecting strong "green momentum" into
