四川最大燃气电站4号机组投产发电

Core Viewpoint - The Dazhou Gas Power Plant's Phase II project has successfully commenced commercial operations with the completion of the 4th unit, increasing the total installed capacity to 2.18 million kilowatts, making it the largest gas power plant in Sichuan [1][3]. Group 1: Project Overview - The Dazhou Gas Power Plant Phase II project began construction in November 2023 with a total investment of approximately 3.4 billion yuan, and it is a key project in Sichuan's "14th Five-Year" energy development plan [3]. - The project includes the construction of two gas-steam combined cycle generator units, the 3rd and 4th units, each with a capacity of 740,000 kilowatts [3]. Group 2: Technical and Operational Efficiency - The new units in the Phase II project have a gas-steam combined cycle efficiency exceeding 60%, significantly reducing the cost per kilowatt-hour and emissions, while also enhancing rapid startup capabilities and operational flexibility [5]. - The estimated annual gas consumption for the four units is approximately 785 million cubic meters, with an expected annual power generation of 3.924 billion kilowatt-hours [5]. Group 3: Regional Energy Impact - The Dazhou Gas Power Plant will enhance energy security in the Chengdu-Chongqing economic circle and promote the local conversion and efficient use of natural gas [5]. - Dazhou's total installed capacity is projected to increase significantly, with plans for additional coal-fired and renewable energy projects, aiming to reach nearly 7 million kilowatts by 2027 and over 8 million kilowatts by 2030 [5].
