Fighting through the fourth quarter to win the whole year! Recently, the Tibet Amdo and Qinghai Golmud solar thermal power projects undertaken by SEPCO1 (Shandong Electric Power Construction No.1 Company) in high-altitude regions have seized the golden construction period before the arrival of winter, reporting a stream of good news and successively achieving milestone nodes, driving high-quality project delivery and supporting the construction of a new-type power system.

The absorber tower foundations of the world's largest single-unit "three towers, one turbine" solar thermal power station have all "broken ground level"

On November 20, the foundation concrete pouring for the three absorber towers of the Qinghai Yichu Golmud 350 MW solar thermal project undertaken by SEPCO1 was fully completed, smoothly achieving the "breaking ground level" milestone for the foundations and fully entering the superstructure construction phase.

As the tower-type solar thermal power project with the world's largest single-unit scale, largest heliostat field reflective area, largest energy storage scale, and highest designed annual power generation, it adopts China's independently developed core tower-type molten salt energy storage solar thermal power generation technology and has achieved multiple major technological innovation breakthroughs. It is the first to apply the "three towers, one turbine" scheme (i.e., three absorber towers collaboratively collecting heat and sharing a single steam turbine for power generation). Since the project started, in the face of the difficulties and challenges brought by the high altitude of the Qinghai-Tibet Plateau, the SEPCO1 project team has organized scientifically and dispatched precisely. Under the premise of ensuring construction safety and quality, it has fully advanced the construction schedule, completing the first concrete pouring of Absorber Tower No. 1 on October 27, and efficiently completing the key engineering milestone of "breaking ground level" for the three absorber towers in a short period, demonstrating the power-construction iron army's capability in solar thermal project construction and engineering management under complex environments.

The project has a heliostat field area of approximately 3.3 million square meters and is equipped with a 14-hour molten salt energy storage system. After completion, it is expected to generate approximately 960 million kWh of clean electricity annually, equivalent to saving 263,400 tons of standard coal and reducing carbon dioxide emissions by 720,000 tons. It will effectively alleviate the shortage of flexible peak-shaving power sources in Qinghai Province, provide solid support for the safe and stable operation of the regional power grid, strongly promote the consumption of new energy such as wind power and photovoltaics, and be of great significance in helping Qinghai build a national clean energy industry highland.

The absorber tower of the world's highest-altitude and Tibet's first tower-type solar thermal power station has been topped out

On November 15, the absorber tower of the Tibet Kaotou Amdo Tushuo 100 MW solar thermal project undertaken by SEPCO1 was smoothly topped out. The project took only 233 days from groundbreaking to completion of the main structure, achieving topping out in the same year as commencement and setting the fastest topping-out record for projects of the same type at ultra-high altitudes, providing a replicable "Chinese solution" for clean energy development in high-altitude regions worldwide, and attracting attention and coverage from multiple media outlets including People's Daily and Xinhua News Agency.

As the project's "energy hub," the absorber tower has a barrel height of 185 meters, a bottom radius of 12.5 meters, and a top diameter of 8.5 meters. The tower top must carry heavy equipment such as the screen-protected absorber, with a total load exceeding 1,800 tons. Since the project started, in the face of the complex environment of cold and high-altitude regions, the SEPCO1 project team, in the spirit of "short of oxygen but not short of spirit, higher altitude means higher morale," has coordinated scientifically and organized meticulously, overcoming external adverse factors such as the plateau environment and severe weather. It has built a safety protection and quality assurance system covering the entire construction process, integrated the "smart construction site" into construction process management, and coordinated the deployment of construction production work, effectively ensuring the safe and smooth topping out of the absorber tower's main structure.

It is reported that after completion, the project is expected to generate approximately 260 million kWh annually, with annual utilization hours of about 2,551 hours, capable of meeting the electricity demand of approximately 200,000 households, equivalent to saving 60,000 tons of standard coal and reducing carbon dioxide emissions by approximately 165,000 tons per year. It can provide stable clean electricity to Amdo County and surrounding areas, inject strong green momentum into the Tibet power grid, and also provide valuable experience and solutions for large-scale clean energy development in cold and high-altitude regions.

SEPCO1 has long been deeply engaged in the solar thermal business field, having successively built the PowerChina Qinghai Gonghe 50 MW tower-type solar thermal power generation national demonstration project and the Lanzhou Dacheng Dunhuang 50 MW molten salt linear Fresnel solar thermal power generation demonstration project, among others, supporting the large-scale commercial application of solar thermal power generation technology. Next, SEPCO1 will firmly grasp the safety, quality, and schedule management of solar thermal projects under construction, leverage its professional advantages and core competitiveness, build high-quality brand projects, and contribute the strength of the power-construction iron army to building a new-type power system.
