China Southern Power Grid Co., Ltd. resolutely implements the decisions and deployments of the Party Central Committee and the State Council, and through a new arrangement of 10 billion yuan in fixed assets investment in power grids, multiple measures are taken to help small and medium-sized enterprises solve their problems, give full play to the strategic supporting role of power grid companies in helping the high-quality development of the real economy, and fully serve " The overall situation of "six stability" and "six guarantees" provides strong support for stabilizing the macroeconomic market. According to reports, in 2022, China Southern Power Grid plans to invest 125 billion yuan in fixed assets, 20% more than in previous years. In the first four months of 2022, 30.3 billion yuan in fixed assets has been invested, a year-on-year increase of 7.4%.

Newly arranged 10 billion yuan investment to help stabilize the economic market

In order to implement the relevant policy requirements for stabilizing the economy, China Southern Power Grid has recently arranged a new 10 billion yuan investment in fixed assets in the power grid, focusing on ensuring safe production, reliable power supply, and new energy supply and consumption, to further improve Guangdong, Guangxi, Yunnan and Guizhou. . The energy supply guarantee capacity of the five provinces and regions in Hainan, promote the construction of new power systems, ensure that more than 51 million kilowatts of newly built units are connected to the grid within the year, and support the annual west-to-east power transmission of no less than 222 billion kilowatt-hours.

1. In Guangdong, the 500 kV Pengcheng Substation in Shenzhen is busy. After on-site investigation and review of drawing design, the station will be equipped with 2 static synchronous compensators (STATCOM devices) to increase the voltage of the power grid in central and western Shenzhen. stable level. At the same time, China Southern Power Grid Guangdong Power Grid Co., Ltd. has fully started the construction of the second phase of the Guangdong Target Grid, which will provide a strong guarantee for the basic construction of an intrinsically safe power grid in the Guangdong-Hong Kong-Macao Greater Bay Area by the end of 2023.

2. In Guizhou, the 500 kV Shexiang to Yaxi power transmission and transformation project has entered the construction stage of the tower assembly. This power transmission project is the channel for sending surplus clean energy such as hydropower, wind power and photovoltaics in Bijie. It is understood that China Southern Power Grid Guizhou Power Grid Company will help absorb more clean energy from northern Guizhou by accelerating the construction of a number of power transmission and transformation projects.

3. In Yunnan, the Southern Power Grid Yunnan Power Grid Company will focus on implementing the rural power grid transformation and upgrading project, complete the comprehensive treatment of low voltage problems, improve the quality of power supply in the distribution network, and improve the living conditions of residents.

In 2022, China Southern Power Grid plans to invest 125 billion yuan in fixed assets, 20% more than in previous years. In addition to a series of key projects in the Guangdong-Hong Kong-Macao Greater Bay Area, the increased investment projects mainly focus on new energy transmission supporting grid projects and pumped storage projects.

On May 25, the DC back-to-back power grid project in the Guangdong-Hong Kong-Macao Greater Bay Area was officially put into operation. It is expected that in 2022, it will support no less than 188.3 billion kWh of power transmission from west to east. On May 28, two million-kilowatt-level pumped-storage power stations in Meizhou and Yangjiang, Guangdong were put into operation at the same time. The total installed capacity of pumped-storage power grids in the Guangdong-Hong Kong-Macao Greater Bay Area is nearly 10 million kilowatts, and the peak power generation capacity during peak hours has been greatly improved. In addition, Yunnan, Guizhou, and Guangxi have a total of 6 supporting grid projects for China's first large-scale wind power photovoltaic bases have started construction, with a total installed capacity of 11.7 million kilowatts of new energy.

According to reports, China Southern Power Grid will focus on the construction of 44 key projects. These projects will effectively drive the development of the upstream and downstream industrial chains. Only the DC back-to-back project in the Greater Bay Area involves nearly 200 upstream and downstream enterprises in the industry, which can directly drive the scale of equipment production.
