What is China Southern power grid?

China Southern Power Grid (“Southern Grid”) is one of China’s two major state-owned power distributors that serve five southern provinces: Guangdong, Guangxi, Yunnan, Guizhou and Hainan. The region has witnessed a rapid build-up of power generation capacity, from 275 GW in 2015 to 350 GW in 2020.

Which river basins feed the China Southern power grid (CSPG)?

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). All riparian countries in which the transboundary basins ow are shown on the map.

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 to simulate the long-term development of the CSPG's electricity system?

To simulate the long-term development of the CSPG’s electricity system, we used an open-source power system modeling platform (GridPath) 26, 53.

Which CSPG basins are covered by a hydropower simulation?

The simulation covers six basins across the CSPG, i.e., Mekong, Nujiang, Yangtze, Yuan and Red, Pearl, and QSGCRB, which encompass more than 120 GW of existing hydropower capacity and 32 GW of projected hydropower capacity 58 (Table S14).

Which generation capacities are available in China?

Existing generation capacities—mostly consisting of hydropower and coal, with a small share of gas, nuclear, biomass, PSH, wind, and solar—were retrieved from the China Electricity Council 57 and PEC of each province in the CSPG. We consider candidate capacities for coal, gas, biomass, nuclear, and PSH that have existing installed capacities.
