Chinese sources reported on the inclusion in the national distribution network of China of the first stage of solar power plants from the so-called “desert” cluster. In the Gobi desert and other arid regions of the country, it is planned to deploy up to 450 GW of solar and wind capacities. The capacity of the first solar station connected to the grid was 1 GW. Electricity from it will be transmitted to the central Chinese province of Hunan through high-voltage lines, and this may have consequences.

The desert power plant project involves the creation of very, very long high-voltage transmission lines for electricity. To reduce losses at such distances, it was decided to increase the transmitted voltage from 800 kV to 1100 kV. By comparison, high-voltage transmission lines in the United States use 500 kV. An increase in voltage is accompanied by an increase in the strength of the electromagnetic field along the route and leads to geomagnetic anomalies.
This can result in more frequent thunderstorms, a change in the Earth’s magnetic field pattern, malfunctions in positioning systems, and satellite data corruption. There is no particular clarity on this issue. China will be the first to experience all this in practice.
The operator of the newly commissioned first stage of power plants is China Energy Investment Corp. A solar farm with a capacity of 1 GW will have to generate up to 1,800 GWh per year, which is equivalent to the electricity needs of 1.5 million households, the company says. The project provides for a total installed capacity of 13 GW and is estimated at 85 billion yuan ($12.28 billion).
China’s renewable energy installed capacity continued to grow in the first quarter, reaching 47.4 GW, up 86.5% year-over-year and accounting for 80.3% of total newly added installed capacity, according to NEA. . New installed capacity in wind power rose to 10.4 GW and solar power to 33.66 GW, the report said.
In the first quarter, China’s total installed renewable energy capacity reached 1,260 GW, including 376 GW of wind power and 425 GW of photovoltaic power.
Renewable electricity generation is also steadily increasing, with national renewable electricity generation reaching 594,700 GWh, up 11.4% year-on-year, including 342,200 GWh from wind and solar, up 27.8% more than a year earlier.
