en.Wedoany.com Reported - At 15:50 on May 31, Unit 1 of the Liupanshui Dawan 2×660 MW Low-Calorific Value (CFB) Coal Power Project, led by China Energy Engineering Group Hunan Electric Power Design Institute Co., Ltd. under China Energy Engineering Corporation, successfully achieved grid connection and power generation. This milestone marks the successful completion of key equipment installation and system commissioning tasks, confirming the unit's capability to stably transmit power to the grid, laying the foundation for subsequent 168-hour full-load trial operation and commercial operation.

This project is a key energy construction project in Guizhou Province and a vital support for building the province into a new comprehensive energy strategic base. With a total investment of approximately RMB 5.18 billion, it plans to construct two 660 MW ultra-supercritical circulating fluidized bed power generating units. Leveraging regional resource endowments, the project primarily utilizes low-calorific value fuels such as coal gangue and coal slime for comprehensive power generation, aiming to enhance the resource utilization rate of waste coal resources and practice green and low-carbon development concepts.

The project adopts advanced ultra-supercritical circulating fluidized bed power generation technology, featuring strong fuel adaptability and the ability to efficiently consume low-calorific value, low-grade coal resources, resulting in high power generation efficiency and outstanding economic and environmental benefits. The project is equipped with a full set of high-standard environmental protection facilities, including efficient dust removal, desulfurization, and denitrification systems, strictly implementing ultra-low emission standards and water resource recycling measures, committed to building an eco-friendly green power plant. Concurrently, the project promotes multi-energy integrated development, supporting the layout of new energy projects to foster coordinated development between traditional thermal power and clean energy. It also accelerates the construction of a smart power plant, establishing an integrated intelligent operation and maintenance control platform to enhance the plant's intelligent management level and safe production operation efficiency.

Upon completion and commissioning, the project will effectively revitalize local low-calorific value coal resources, drive the coordinated development of upstream and downstream related industries such as local transportation, building materials, and labor services, and stably boost local employment and income. Furthermore, the project will add high-quality main power sources to the Guizhou power grid, enhancing the regional grid's power supply guarantee capacity and flexible peak-shaving capability, expanding the absorption capacity for regional wind power, photovoltaic, and other new energy sources, continuously optimizing the province's energy and power structure, and providing power security for high-quality local economic and social development.

Since the full commencement of project construction, all participating personnel have closely followed the construction milestones, successively completing a series of major construction tasks, including the topping out of main buildings, chemical water production, boiler hydrostatic test, boiler ignition and pipe blowing, auxiliary power receiving, and turbine speed-up and stabilization, gradually turning the planning blueprint into a physical project.

Following the grid connection command, the entire grid connection process proceeded orderly. The operation status of the unit's auxiliary systems, thermal systems, and electrical systems remained stable, with all operating parameters meeting excellent standards. Unit 1 of the Dawan Coal Power Project achieved successful grid connection on its first attempt. In the next steps, the project department will scientifically coordinate the commissioning plan, refine operational assurance measures, and advance all work for the 168-hour full-load trial operation, striving for the early formal commercial operation of Unit 1 to release the project's comprehensive energy benefits.
