On August 28, it was announced that Guangdong Taishan Power Plant’s 600 MW subcritical water cooling unit parameter upgrading project has been selected as a typical case in the 2024 coal-fired power units for promoting green and low-carbon-oriented transformation and development under the joint operation of three types of technical reforms initiative by the China Electricity Council (CEC).
This recognition comes as part of a nationwide effort by CEC to promote exemplary cases and practices with mature technical advancements and outstanding comprehensive benefits in supporting the coal-fired power transformation and upgrade process. After a thorough review process, including formal and technical evaluations, 48 typical cases were selected. In this project, the main reheat steam parameters of Unit 2 at Taishan Power Plant were elevated from 16.7 MPa/537°C/537°C to 17 MPa/600°C/600°C, increasing the unit’s capacity from 600 MW to 630 MW. The turbine, boiler, generator, and auxiliary equipment underwent complementary upgrades as well. The project also pioneered ten core technologies with independent intellectual property rights, including steam-water process reengineering and turbine technology integration, achieving a generational leap in both boiler and turbine performance.
After the transformation, the unit’s coal consumption for power generation decreased from 314.52 g/kWh to 288.58 g/kWh, a reduction of 25.94 g/kWh. The selection of this project as a demonstration case highlights Taishan Power Plant’s achievement in setting a national benchmark for the joint operation of three types of technical reforms of subcritical units and contributes to CHN Energy’s solution for building a new type power system in China.
