  On the banks of the Qin River, in the neighbourhood of Emperor Kangxi’s former residence Huangcheng Xiangfu, and in the Shanxi Yangcheng Power Plant, a pioneering enterprise in China’s “West-to-East Power Transmission”, there are continuous grasslands.

In recent years, Yangcheng Power Plant has focused on the "dual-carbon" goal and built a world-class energy supplier with "green and low-carbon, multi-energy complementary, efficient coordination, and digital wisdom", actively exploring and practicing low-carbon, clean, safe and efficient environmental protection innovations. model.

  The Yangcheng Power Plant has a total installed capacity of 3.3 million kilowatts, and it transmits power to Jiangsu by means of dedicated plants, dedicated lines, and dedicated supply, with a transmission distance of 760 kilometers.

Yangcheng Power Plant is the first in the country to "transmit power from west to east". It is the country's first demonstration project of transforming coal transmission into power transmission, the country's first trans-regional long-distance ultra-high voltage AC power generation and transmission project, and the country's first national power transmission project. A power plant directly dispatched by the power dispatching communication center.

  According to reports, the Yangcheng Power Plant sends about 17 billion kWh of electricity to Jiangsu each year, which is equivalent to transporting more than 7 million tons of raw coal. This is to alleviate the power shortage situation in Jiangsu Province with rapid economic development, promote the economic development of Shanxi, and ease the pressure on coal transportation from Shanxi. It has played a positive role and has established a demonstration of complementary advantages and common development of energy base provinces and economically developed provinces, and has good economic, environmental and social benefits.

  In recent years, Yangcheng Power Plant has produced ultra-low emissions.

"Under the background of'dual carbon', environmental protection requirements are becoming more and more stringent. Especially for Yangcheng Power Plant, which is close to the scenic spot, environmental protection issues are particularly urgent and the top priority." Liu Linhu, deputy chief engineer of Yangcheng Power Plant, introduced , Yangcheng Power Plant focuses on the "dual-carbon" goal, exploring and practicing a new model of low-carbon, clean, safe and efficient environmental protection.

  In accordance with the ultra-low emission retrofit requirements of the Shanxi Provincial Government, in 2016, Yangcheng Power Plant invested about 280 million yuan to complete the ultra-low emission retrofit for units 1-4, and in 2017, it invested about 440 million yuan to complete the ultra-low emission retrofit for units 5-8 .

  After the ultra-low emission transformation of the unit is completed, the concentration of smoke and dust is not more than 5 mg/m3, the concentration of sulfur dioxide is not more than 35 mg/m3, and the concentration of nitrogen oxides is not more than 50 mg/m3.

During the normal operation of the unit, the three pollutant emission indicators are controlled below 80% of the standard limit to ensure that the emission is stable and meets the standard.

  "Invest in comprehensive management of flue gas pollutant emissions, combine point and surface, and strictly control unorganized emission pollution. Real-time environmental protection data is transparent, and automatic online monitoring of flue gas and wastewater has been realized. At the same time, it actively obeys the state's carbon The strategic goal of “peak and carbon neutral” is to make every effort to build a solar thermal storage base, and to promote the construction of a first-class integrated energy base at full speed." Liu Linhu said that while actively building a "green power plant", Yangcheng Power Plant actively assumes social responsibility and actively serves local construction , To promote the construction of "Warm Yangcheng", use the waste heat of the power plant to heat and heat Yangcheng County and surrounding towns and towns, and the heating area has reached 5.8 million square meters.

  “At present, the heating renovation project to Jincheng City is actively advancing. The project adopts long-distance, large temperature difference heating technology, and the planned heating area is about 30 million square meters, covering Xicheng District, Zezhou County, and surrounding villages and towns in Jincheng City. , The beneficiary population is about 600,000 people."

  It is reported that after the project is fully completed, it will form a complementary pattern with the two major heat sources of the East and the West with the SDIC Power Plant, helping to achieve clean heating in all urban areas, which has obvious environmental and social benefits.

According to Lang Shihua, director of the Jincheng City Ecological Environment Bureau, the industrial steam supply transformation project of Yangcheng Power Plant to the surrounding industrial parks is also being actively promoted.

  Li Lizhen, vice chairman of the Shanxi Environmental Protection Industry Association, said that Yangcheng Power Plant will be the first to test and complete the ultra-low renovation in 2017.

Under the new situation of carbon peak and carbon neutrality, new modes of operation can be explored: reducing coal consumption for power supply, carbon capture at the end, reducing carbon emissions, and ultimately achieving sustainable development of safety, stability, environmental protection, and energy saving.
