China Southern Power Grid solves 2.25 million people's electricity problem

China Southern Power Grid solves 2.25 million people's electricity problem In the past ten years, China Southern Power Grid has invested a total of 524.1 billion yuan to build the power grid. It has more than tripled the total investment since the founding of New China in 2002. Accumulative power sales amounted to 474.1 billion kWh, resulting in 13 crosses and 13 straight lines covering thousands of kilometers. The grand channel rationalized the agricultural power management system in five provinces and solved the power problem of 2.25 million people without electricity.

On December 29, China Southern Power Grid Corporation (“South China Power Grid”) held its tenth anniversary conference.

In the past ten years, China Southern Power Grid has invested a total of RMB 524.1 billion to build the power grid, which is more than three times the total investment since the founding of the People’s Republic of China in 2002, said Zhao Jianguo, chairman of China Southern Power Grid. In the ten years, the unified grid of five provinces and regions in China Southern Power Grid built a safe, stable large-scale, long-distance, ultra-high-pressure transmission and closely connected unified power grid, creating a GDP that can support the five southern provinces. High-speed growth of more than 12% of physical platforms. In the past ten years, China Southern Power Grid accumulated 47,410 billion kilowatt-hours of electricity sales, formed 13 large-scale channels of “eight exchanges and five directs” and thousands of kilometers, rationalized the agricultural power management system in five provinces and regions, and solved the power consumption of 2.25 million people without electricity. problem.

Ten years ago, as a pilot field for the reform of the central power system, China Southern Power Grid took over the five southern provinces and regions, one of the most severely power-hungry areas in China, without precedent. At the beginning of its establishment, China Southern Power Grid faced a series of difficulties and tests. At that time, GDP accounted for nearly 70% of Guangdong's five provinces and regions. The problem of power shortage has become a bottleneck restricting its economic development. At the same time, the cross-regional linkages between Yunnan, Guizhou, Guangxi, and Guangdong provinces are still weak. The three southwestern provinces and Guangdong have only four “three-way intersections” and the transmission capacity is only 3.7 million kilowatts. Hainan’s power grid still stands in front of the “island grid”. hat.

In 2009, Hainan Power Grid ended its history of running a lone network for a century and merged into the main grid of China Southern Power Grid. Asia’s first and the world’s second 500 kV AC submarine cable—the 500 kV Hainan interconnection project was put into operation. The main grid of China Southern Power Grid crossed the Qiongzhou Strait and Hainan Power Grid “in hand” on the sea floor.

This platform is still constantly expanding. At present, the amount of electricity delivered to Hong Kong through the transmission network of China Southern Power Grid Corporation accounts for about half of its electricity consumption. The electricity delivered to Macao accounts for about 90% of its electricity consumption, and the reliability of electricity supply is 100%. This makes Hong Kong and Macau the two pearls. More dazzling.

As the Chinese executive unit of the Greater Mekong Subregion Power Cooperation Project, China Southern Power Grid has promoted regional power cooperation and has achieved interconnection with Burma, Vietnam, and Laos power grids. Zhao Jianguo said, “Going out is not easy, but the responsibility lies and the economy needs, and it will continue to advance in the future.”

In the next decade's blueprint for development, the strategic objectives of China Southern Power Grid have been established: by 2020, an international advanced power grid enterprise will be established to provide green support for “Beautiful China”, which is also a “wind vane” for the operations of 318,000 South China Nets.
