The country's first 550 megawatt F-class gas turbine unit was put into operation today, marking a new breakthrough in large capacity clean energy equipment.

On March 21st, the first 550-megawatt F-class gas turbine unit in China, the No. 1 unit of Huaneng Chongqing Tongnan Power Plant, successfully completed a 168-hour full-load trial operation and officially started power generation. This milestone event signifies an important breakthrough for China in the application of large-capacity, high-efficiency, and clean energy equipment. This unit has two core technological advantages: first, it can operate as an island and quickly restore power supply in the event of a grid failure, effectively ensuring power supply security in extreme situations; second, each unit is equipped with two outgoing lines, so even if one line fails, full-load stable power generation can still be maintained, significantly improving the reliability of power transmission and the security of energy supply in the region. F-class gas turbines are one of the mainstream high-efficiency power generation technologies internationally. They are characterized by rapid start-ups, flexible load adjustments, and are an important force for peak regulation and emergency support in power systems. The commissioning of the No. 1 unit of Huaneng Chongqing Tongnan Power Plant will provide strong support for the stability of power supply in the southwest region.
