Can China decarbonize the southern power grid by 2060?

Decarbonization of the Southern Power Grid in China is feasible by 2060 but requires converting a large cropland area to support solar and wind energy; expansion of hydropower will impact the transboundary rivers according to a power system optimization model set up for 2020–2060.

How many kilowatt-hours does China Southern power grid use?

China Southern Power Grid said the five regions that it covers have consumed 540 billion kilowatt-hours of clean energy during the first nine months, with the renewable energy generation efficiency reaching 99.81 percent, up 0.22 percent year-on-year. Newly added installation of new energy reached 3.31 million kWs.

[Photo/Xinhua] China Southern Power Grid, one of the country's two major power grids, vowed to invest 670 billion yuan ($105 billion) recently in grid network construction during the 14th Five-Year Plan period (2021-25) to ensure power supply stability and boost green power consumption.

How many power grids are there in China?

As a hierarchical multi-area power system with multi-level dispatch centers, CSG governs five provincial power grids: Guangdong Power Grid (GDPG), Guangxi Power Grid (GXPG), Guizhou Power Grid (GZPG), Yunnan Power Grid (YNPG), and Hainan Power Grid (HNPG), which serve more than 252 million people (the basic overview is shown in Fig. 1 ).

How much will China's power grid invest in 2021-25?

State Grid Corp of China, the largest power provider in the country, also pledged to invest 2.23 trillion yuan in the power grid, which means the country's total grid network investment will soar to 3 trillion yuan during the 2021-25 period. Both companies vowed to increase power supplies while implementing power price reforms.

Which components of the power grid are modeled with gridpath?

All components of the power grid are modeled with GridPath. b The map illustrates the river basins whose hydropower dams feed the China Southern Power Grid (CSPG). These basins are the Mekong, Nujiang, and Red (transboundary) and the Yangtze, Pearl, Qionglei and Southeast Guangxi Coastal river basins (QSGCRB).
