On June 9, Guangdong Yunfu O&M Project Team announced exciting news: Unit 3 and Unit 4 achieved successful first-attempt grid connection on June 5 and June 9 respectively, following the completion of their B-level overhaul.

The overhaul commenced on May 1. Facing challenges such as tight schedules and heavy workloads, the project team adhered to the principles of "advance preparation and lean operation", coordinated all participating units for efficient collaboration, strictly controlled maintenance quality, and completed core tasks including equipment inspection and defect resolution, laying a solid foundation for the units' restart.Post-overhaul, the team promptly initiated startup preparations, conducting systematic risk assessments, optimizing system conditions, and enhancing safety measures to ensure "zero defects and zero delays" throughout the process.Ultimately, with the green lights illuminating the control room screens, Unit 3 achieved first-attempt grid connection at 13:05 on June 5, followed by Unit 4 at 11:44 on June 9. This fully demonstrated the team's professional expertise and end-to-end management capabilities, ensuring stable power supply for the plant.

Moving forward, the project team will uphold the working philosophy of "risk mitigation, contract fulfillment, management enhancement, and efficiency improvement", strictly follow commissioning procedures, and maintain high standards for operation and maintenance after grid connection to ensure the plant's long-term safe and stable operation.
