Recently, the No. 2 unit of the State Power Investment Corporation (SPIC) Qinghai Provincial Investment 3×660 MW "replace small units with large ones" thermal power project, constructed by PowerChina Nuclear Engineering Company, successfully completed its 168-hour full-load trial operation and was officially put into commercial operation. The power plant is the first to apply "domestically produced ultra-supercritical unit intermediate-pressure rotor equipment," becoming the industry's first "first-of-its-kind" demonstration case and laying an important foundation for the promotion of domestic production of core equipment for ultra-supercritical units in China.

The project is the thermal power unit project with the largest capacity, best performance, and highest degree of intelligence in Qinghai Power Grid's 750 kV system. Adopting the "replace small units with large ones" model, it was built on the original site after demolishing five old units. It is not only the thermal power unit with the largest capacity and the best design performance indicators in Qinghai Province, but also the province's first high-altitude smart thermal power plant. Its commissioning has effectively filled the gap in large-capacity flexible regulation power sources on the plateau, enhanced the level of clean energy consumption through deep peak-shaving capability, and laid a solid foundation for Qinghai to build a national clean energy industry highland.

The unit pioneers an industry-leading safe and environmentally friendly operating mode featuring no hydrogen, no fuel oil, and no liquid ammonia, integrating multiple cutting-edge technologies. Its standard coal consumption for power generation has been reduced to 284.4 g/kWh, achieving higher output with lower energy consumption and providing a replicable "Chinese solution" for high-altitude thermal power projects worldwide. After full completion, annual power generation is expected to reach 8 billion kWh, with an estimated annual reduction of 2 million tons of carbon dioxide, significantly enhancing the province's power supply guarantee capacity and injecting strong momentum into local industrial upgrading, livelihood improvement, and high-quality economic and social development, achieving a win-win outcome for both economic and ecological benefits.
