The expansion project of Guoxin Jingjiang Power Plant in Jingjiang, East China's Jiangsu province, has marked a significant milestone, as its No 3 unit was successfully connected to the grid for the first time on Nov 28.
This achievement represents the most crucial step before the official commissioning of the project, which involves construction of two 1,000 MW ultra-supercritical double-reheat coal-fired power generation units and associated auxiliary facilities, highlighting a major breakthrough in the development of major projects within the Jingjiang Economic and Technological Development Zone.
With a total investment of 8.39 billion yuan ($1.18 billion), the project is poised to play a vital role in ensuring energy security, power supply stability, and system regulation, serving as a key project helping Jingjiang integrate into the national energy strategy. Since its commencement at the end of 2023, work on the project has progressed smoothly.
The project employs internationally advanced ultra-supercritical double-reheat coal-fired power generation technology. During its construction, it achieved 55 technology patents, with a standard coal consumption rate of less than 250 grams per kilowatt-hour, positioning it at the forefront of similar domestic units. Furthermore, the project includes the construction of desulfurization, denitrification, and high-efficiency dust removal facilities, utilizing the latest environmental protection technologies to achieve "near-zero emissions" of pollutants.
Additionally, the project integrates big data into a comprehensive equipment health management system, enabling 24-hour real-time monitoring and intelligent diagnostics of equipment operating status, aiming to create a smart power plant.
Once fully operational, the project is expected to generate 10 billion kilowatt-hours of power annually, meeting the annual electricity needs of 5 million households. It will provide essential energy support for the integrated development of the Yangtze River Delta.
