China Southern Power Grid Company Limited (CSG; : 中国南方电网; : Zhōngguó Nánfāng Diànwǎng) is one of the two Chinese established in 2002 in a power system reform promulgated by the , the other being the (SGCC). It is overseen by the It has 13 wholly-owned subsidiaries – power grid companies in Guangdong, Guangxi, Yunnan, Guizhou and Hainan, power supply bureaus in Guangzhou and Shenzhen, CSG International, Dingxin Technology, .

China Southern Power Grid International Co., Ltd. (CSGI) founded in 2007, and China Southern Power Grid International Hong Kong Co., Ltd.,or CSGI (HK) founded in 2005, both wholly-owned subsidiaries of CSG, are the executor of CSG’s international businesses. CSGI and CSGI(HK)currently share the same staff force.
In accordance with a State Council rule on electric power system reform, China Southern Power Grid Co was officially launched and put into operation on Dec 29, 2002. It is a centrally-administered company, with the State-owned Assets Supervision and Administration Commission of the State Council (SASAC) performing duties as its investor.
It has 13 wholly-owned subsidiaries – power grid companies in Guangdong, Guangxi, Yunnan, Guizhou and Hainan, power supply bureaus in Guangzhou and Shenzhen, CSG International, Dingxin Technology, Dingyuan Asset Management, CSG Materials & Equipment Co, Capital Holding Co, and CSG Energy Academy.
Southern power grids extend approximately 2,000 kilometers from east to west, covering a variety of sources for power generation, including water, coal, nuclear, pumped storage, oil, gas and wind.
CSG headquarters has 20 functional departments, as well as the Electric Power Dispatching and Control Center, and manages 5 branches, 13 wholly-owned subsidiaries and 9 holding subsidiaries, with a total of nearly 276,000 employees.

Photovoltaic research in China began in 1958 with the development of China's first piece of . Research continued with the development of solar cells for space satellites in 1968. The Institute of Semiconductors of the led this research for a year, stopping after batteries failed to operate. Other research institutions continued the developm. China surpassed Germany as the world's largest producer of photovoltaic energy in 2015, [2][3] and became the first country to have over 100 GW of total installed photovoltaic capacity in 2017.

With the world's largest, most complete new-energy industry chain, China is expected to install 230 to 260 gigawatts of solar capacity this year, topping the record of 217 GW set last year, according to the China Photovoltaic Industry Association.
China can now make more solar power than the rest of the world. Data released by China’s National Agency last week revealed that the country’s solar electric power generation capacity grew by a staggering 55.2 percent in 2023. The numbers highlight over 216 gigawatts (GW) of solar power China built during the year.
As of at least 2024, China has one third of the world's installed solar panel capacity. Most of China's solar power is generated within its western provinces and is transferred to other regions of the country.
China is on track to set a new record for solar power installations in 2024, driven by falling production costs and increased global interest in renewable energy, said industry experts and company executives.
"Solar PV installations have maintained a quite high pace this year, and we had seen an average of over 18 GW of monthly installations this year in China till October," said Zhu Yicong, vice-president of renewables and power research at global consultancy Rystad Energy.
As such, critics argue that investments into renewable energy sources such as solar power are means to increase the power of the central state rather than protect the environment. This argument has been complemented by China's expansion of fossil fuel plants in conjunction with solar energy.

China produces 63% of the world's solar photovoltaics (PV). [45] [pdf]
Global solar PV manufacturing capacity has increasingly moved from Europe, Japan and the United States to China over the last decade. China has invested over USD 50 billion in new PV supply capacity – ten times more than Europe − and created more than 300 000 manufacturing jobs across the solar PV value chain since 2011.
China has invested over USD 50 billion in new PV supply capacity – ten times more than Europe − and created more than 300 000 manufacturing jobs across the solar PV value chain since 2011. Today, China’s share in all the manufacturing stages of solar panels (such as polysilicon, ingots, wafers, cells and modules) exceeds 80%.
In 2019, China's newly installed grid-connected photovoltaic capacity reached 30.1GW, a year-on-year decrease of 31.99%, of which the installed capacity of centralized photovoltaic power plants was 17.9GW, a year-on-year decrease of 22.9%; the installed capacity of distributed photovoltaic power plants was 12.2GW, a year-on-year increase of 17.3%.
Most of China's solar power is generated within its western provinces and is transferred to other regions of the country. In 2011, China owned the largest solar power plant in the world at the time, the Huanghe Hydropower Golmud Solar Park, which had a photovoltaic capacity of 200 MW.
As of at least 2024, China has one third of the world's installed solar panel capacity. Most of China's solar power is generated within its western provinces and is transferred to other regions of the country.
Continuous innovation led by China has halved the emissions intensity of solar PV manufacturing since 2011. This is the result of more efficient use of materials and energy – and greater low-carbon electricity production.
