In 2021, my country's newly installed photovoltaic capacity is 53GW, calculated at a cost of 4,000 yuan/kW, which is more than 200 billion points, which also includes civil construction and other costs. From this point of view, compared with the domestic market size of 28.4 billion US dollars, it is completely a half-to-half relationship. Domestic photovoltaic companies have achieved perfect domestic and foreign markets. In this way, even in 2017, photovoltaics are hot and the installed capacity has broken through. With a capacity of 53 million kilowatts, in the face of the sudden brake in 2018, domestic photovoltaic enterprises are still living well, and the development momentum is unabated. It should be said that a stable overseas market has contributed to the stable development of the domestic photovoltaic industry.

According to foreign media reports, affected by the eruption of the submarine volcano, the submarine cable of Tonga in the South Pacific island country has been confirmed to be cut off, and the national telephone and network lines have been interrupted, and about 105,000 residents on the island have been unable to communicate with the outside world.

The total investment during the "14th Five-Year Plan" period is expected to reach 380 billion yuan According to the power grid construction plans of State Grid, China Southern Power Grid, and Inner Mongolia Power Grid, it is estimated that the cumulative investment during the "14th Five-Year Plan" period will be close to 3 trillion yuan, higher than the 2.8 trillion yuan during the "13th Five-Year Plan" period. According to China Energy News, during the "14th Five-Year Plan" period, the State Grid's UHV investment may reach 380 billion yuan, or it is expected to become an important structural increase in power grid investment.
