Datang Power intends to invest in the construction of two large new energy bases, and the installed capacity of the two projects is very impressive. The two large-scale wind and solar base projects of Datang Power are equipped with large-scale thermal power plants as peak-shaving power sources. Tuoketuo large-scale wind power photovoltaic base new energy projects, including wind power 1.7 million kilowatts, photovoltaic 300,000 kilowatts; Hebei Province Yuxian large wind power photovoltaic base new energy projects, including wind power 200,000 kilowatts, photovoltaic 800,000 kilowatts.

Datang Tuoketuo Power Plant is the largest in-service thermal power plant in the world, with an installed capacity of 6.72 million kilowatts that has been put into operation. It is reported that Tuoketuo large-scale wind power photovoltaic base new energy project has held a construction mobilization meeting on October 20. Datang Group stated that it will strive to transform the world's largest in-service thermal power plant into the world's largest multi-energy complementary integrated energy base, and become a landmark window for the world to see China's energy green transition.

For the new energy project of the large-scale wind power photovoltaic base in Yuxian County, Hebei Province, the peak shaving measures are also the flexible transformation of thermal power. In October 2018, the 2×600,000-kilowatt unit project of Hebei Datang Yuxian Power Plant was connected to the grid for the first time.

These two projects of Datang Group are among the first batch of large-scale wind power photovoltaic base projects in the country.

In 2021, the country's first batch of large-scale wind power photovoltaic base projects will start one after another, and the second batch of new energy large-scale base projects have also begun to declare. Just like the two projects of Datang Group, the new energy base is huge, and many of them start at millions of kilowatts. It is reported that the second batch of large-scale wind power photovoltaic base projects declared requires that the scale of the single project is not less than 1 million kilowatts.

Because of the intermittent and instability of wind power and photovoltaics, such a large-scale new energy installation naturally also needs a strong peak shaving power supply to escort. Therefore, while comprehensively assessing the strength of the owner, the matching peak shaving power supply has also become one of the factors that need to be considered for the new energy base.

The public announcement of the 3.5GW new energy base project in Weinan, Shaanxi showed that Datang Group developed and constructed 2 million kilowatts of new energy projects by reducing thermal power utilization hours and implementing flexible transformations of thermal power units; the remaining 1.5 million kilowatts of new energy projects passed the competition The sexual configuration determines the project development owner.

Datang Group issued a document stating that the 2 million kilowatt new energy project in Weinan, Shaanxi, is also the largest single-scale new energy project approved since the establishment of China Datang.

With the start of Datang Group's "second venture", I believe there will be more new energy "large orders" signed. Thermal power + new energy bases have become a new trend. Not only Datang, but also the five major power plants and many thermal power plants have layouts.

Also in Shaanxi Province, the National Energy Group Guohua Electric Power Jinjie Power Plant and the supporting new energy base have also started. On November 12, 2021, as the national large-scale wind power photovoltaic base Shaanxi Province project centralized construction ceremony was held, the large-scale wind power photovoltaic project of Guoneng Jinjie Company's 1.4 million kilowatts kicked off. Guoneng Jinjie Company is located in Yulin City, Shaanxi Province. It currently has 3.72 million thermal motor assembly machines and 18 million tons of supporting coal mines per year.

Earlier, Hubei Province announced affordable new energy projects in 2021, including 10 million-kilowatt base projects. Flexible adjustment facilities include thermal power plants. There are many million-kilowatt large-scale thermal power plants. They must undertake the task of peak shaving for large new energy bases. , National Energy Group, Huaneng Group, Huadian Group, and State Power Investment Corporation all have thermal power plants on the list.

Due to the intermittent and instability of wind power and photovoltaics, large-scale new energy sources are connected to the grid, and the demand for peak-shaving power is also greater. Many places have clear policies, and the positioning of coal power will change in the future. The new positioning of coal power includes the ability to provide reliable electricity, peak shaving capabilities, and clean heating capabilities.

The "National Coal Power Unit Transformation and Upgrade Implementation Plan" released in 2021 pointed out that the flexibility of existing coal power units should be modified as much as possible. During the "14th Five-Year Plan" period, 200 million kilowatts should be completed and the system's adjustment capacity should be increased by 30-40 million kilowatts.

Will the new energy transition bring more profits to power generation groups?

After the "dual carbon" target was proposed, power generation groups accelerated their pace of transformation. Due to the high fuel costs, the profitability of thermal power plants has long been lower than before. Accelerating the transformation of new energy may be able to bring more profits to power generation companies. The transformation of Huaneng Group has achieved results. During the "13th Five-Year Plan" period, Huaneng Group has built and put into production a total of 15.5 million kilowatts of new energy installed capacity, and the profit contribution of new energy in the power industry has increased from 10% to 50%.

At the end of 2020, Huaneng Group's wind power photovoltaic installed capacity accounted for only 16.16% of the total power installed capacity. In 2021, affected by high coal prices, many thermal power plants are in a loss-making situation. However, as the former "Big Brother of Thermal Power", Huaneng Group's performance in 2021 has stabilized, and its net profit has not yet achieved a substantial decline. I believe that new energy has made a lot of effort in it. Editor/Sang Xiaomei
