According to statistics, from January to July this year, the State Grid Corporation of China has completed a power grid investment of 236.4 billion yuan, a year-on-year increase of 19%. Currently, the total investment in projects under construction is 883.2 billion yuan, including 3,299 110 kV and above power grids and pumped storage power stations. By the end of the year, it is estimated that nearly 300 billion yuan of grid investment will be completed, and a large number of major projects will be started. The total project investment is 416.9 billion yuan, including 1173 power grids and pumped storage power stations of 110 kV and above.
