Core Viewpoint - The project, developed by China Energy Construction and Guangdong Thermal Power, has successfully achieved full-capacity power generation, filling the gap in the domestic "F" class improved single-shaft heavy-duty gas turbine market [2][12]. Project Overview - The project is located in the Jiangjin Comprehensive Bonded Zone of Chongqing and is a key project in Chongqing's 14th Five-Year Plan for electricity [4][14]. - It features the first domestic single-shaft M701F5 heavy-duty gas turbine, with a planned construction of two units of 546.8 megawatts each, totaling an installed capacity of 1,093.6 megawatts [4][14]. Technological Innovations - The project boasts a combined cycle efficiency of 61.74%, which is approximately 2 percentage points higher than similar units, reaching world-leading levels [6][16]. - Over 90% of the equipment is domestically produced, including the first domestic F5 gas turbine TCA (Turbine Cooling Air) system and FGH (Fuel Gas Heater) [6][16]. - The plant's auxiliary power consumption rate is as low as 1.43%, outperforming similar units [6][16]. - The integration of digital technologies has led to the establishment of a smart power plant management platform [6][16]. - Environmental measures ensure ultra-low emissions, with a summer cooling water consumption rate of only 0.267 cubic meters per second per gigawatt [6][16]. Construction Achievements - The project achieved all six core key milestones successfully on the first attempt, with 28 performance indicators meeting or exceeding expectations [8][18]. - The construction period for both units was approximately 19 months, one month shorter than the industry standard, setting a new record for safe and efficient construction [9][19]. - The installation period for the second unit was reduced by an additional 15% compared to the first unit, demonstrating continuous improvement in construction efficiency [9][19]. - The project overcame installation challenges for the first domestic M701F5 gas turbine, achieving micron-level precision in shaft installation [9][20]. - A zero-accident record was maintained during 12 high-risk operations throughout the construction cycle, with a welding first-pass rate of 99.8% and emissions far exceeding national standards [9][21]. Environmental Impact - Once fully operational, the project is expected to generate approximately 2.187 billion kilowatt-hours of electricity annually, saving around 200,000 tons of standard coal compared to equivalent coal-fired units [10][22]. - It is projected to reduce carbon dioxide emissions by over 520,000 tons, providing strong support for Chongqing's long-term electricity demand and enhancing grid peak-shaving capabilities [10][22].
