8月25日，国家电投集团青海省投3×660MW“上大压小”火电项目3号机组顺利通过168小时满负荷试运行，世界海拔最高的高比例掺烧高碱煤660兆瓦超超临界火电机组全容量投运。项目全容量投产后，总装机容量达1980MW，年均可稳定发电80亿千瓦时以上，能够充分覆盖青海省全域用电需求，有效保障全省用电高峰期电力供应，极大提升区域电力供应可靠性与稳定性。

On August 25th, the 3rd unit of the 3×660MW "upgrading large-scale and reducing small-scale" thermal power project of Qinghai Investment of China Power Investment Corporation successfully completed a 168-hour full-load trial operation. The world's highest-altitude, high proportion of blended high-sodium coal-fired power unit with a capacity of 660 megawatts has been fully put into operation. After the full-scale commissioning of the project, the total installed capacity reaches 1980MW, with an annual average stable power generation of over 8 billion kilowatt-hours. It can fully meet the electricity demand of the entire Qinghai Province, effectively ensure the power supply during peak periods in the province, and greatly enhance the reliability and stability of regional power supply.

国家电投集团青海省投3×660兆瓦火电项目，是落实国家能源结构调整政策、推进火电迭代升级、保障区域能源安全的关键性、支撑性标杆电源工程。项目立足青海高海拔、新能源占比高、电网调峰压力大的能源发展现状，严格落实“上大压小、提质增效、绿色升级”能源政策，通过关停替代区域低效老旧小火电机组，新建大容量、高参数、高效率、超低排放的现代化火电机组，从根本上优化了青海省电源结构、补齐电力供应短板，是青海省内核心支撑性电源。

The 3×660-megawatt thermal power project of Qinghai Province invested by China Electric Power Investment Group is a crucial and supportive benchmark power project that implements the national energy structure adjustment policy, promotes the iterative upgrading of thermal power, and ensures the energy security of the region. The project is based on the current energy development situation in Qinghai, which features high altitudes, a high proportion of new energy, and significant pressure on grid peak regulation. It strictly implements the energy policies of "upgrading large-scale power plants and reducing small ones, improving quality and efficiency, and green upgrading", by shutting down and replacing inefficient and outdated small thermal power plants in the region, and building large-capacity, high-parameter, high-efficiency, and ultra-low-emission modern thermal power plants. This fundamentally optimizes the power supply structure in Qinghai Province and fills the gap in power supply, making it a core supporting power source within the province.

该项目作为青海省电网核心支撑电源与主力调峰电源，能够有效平抑新能源出力波动、保障电网安全稳定运行，全方位支撑青海省民生用电、工业负荷、重大项目用电需求，是青海省构建新型电力系统、保障能源可靠供应、推动经济社会高质量发展的重要压舱石。

This project serves as the core supporting power source and main peak-load regulating power source of the Qinghai Province power grid. It can effectively stabilize the fluctuations in the output of new energy, ensure the safe and stable operation of the power grid, and fully support the power demands of people's livelihood, industrial loads, and major projects in Qinghai Province. It is an important stabilizer for Qinghai Province in building a new power system, ensuring reliable energy supply, and promoting high-quality economic and social development.

项目开工建设以来，始终坚持高标准建设、高技术赋能、高环保管控。环保治理层面，项目配套建设先进成熟的石灰石—石膏湿法脱硫、高效除尘、脱硝一体化环保设施，严控大气污染物排放，烟尘、二氧化硫、氮氧化物等排放指标均远优于国家超低排放标准。水资源利用层面，项目创新应用改良型诱晶软化先进水处理技术，每年可消纳城市中水400万吨，全厂生产废水、生活废水实现全闭环循环、100%回用，彻底杜绝废水外排。

Since the project started construction, it has always adhered to high-standard construction, high-tech empowerment, and strict environmental protection control. In terms of environmental protection, the project has comprehensively built advanced and mature limestone-gypsum wet flue gas desulfurization, efficient dust removal, and denitrification integrated environmental protection facilities. It strictly controls the emission of air pollutants, and the emission indicators of smoke dust, sulfur dioxide, and nitrogen oxides are far superior to the national ultra-low emission standards. In terms of water resource utilization, the project innovatively applied improved crystallization softening advanced water treatment technology. Every year, it can consume 4 million tons of urban reclaimed water. The production wastewater and domestic wastewater of the entire plant achieve full closed-loop circulation and 100% reuse, completely eliminating the discharge of wastewater.

设备建设层面，项目坚持自主可控、国产替代建设原则，主机设备、控制系统、关键辅机设备等核心装备全部实现国产化选型应用，成功攻克高海拔低压缺氧、温差大、工况复杂等设备运行适配难题，大幅提升高原火电设备运行稳定性，有效降低运维成本，为国内高海拔大型火电项目设备国产化、建设标准化积累了可复制、可推广的宝贵经验。

At the equipment construction level, the project adheres to the principle of self-control and domestic substitution for construction. All core equipment such as main equipment, control systems, and key auxiliary equipment have achieved domestic selection and application. It successfully overcame challenges such as high-altitude low pressure hypoxia, large temperature differences, and complex working conditions for equipment operation, significantly improving the operational stability of high-altitude thermal power equipment, effectively reducing operation and maintenance costs, and accumulating valuable experience that can be replicated and promoted for domestic high-altitude large-scale thermal power project equipment domestication and construction standardization.
