Abstract:
Water scarcity and uneven water demand in regional electricity generation pose substantial challenges to the sustainable development of water resources and electricity production in China. Based on the latest official policy of China’s electricity development, i.e., the 13th Five-Year Plan of electricity development, this study quantified annual water withdrawal and consumption for future electricity generation in China from 2015 to 2030. This study simulated a three-prong approach to impacting water use for electricity development, i.e., updating the cooling technology mix, increasing non-thermal power generation and relocating thermal power plants to the west. The results showed that solutions to relieve water stress caused by electricity production entail major trade-offs. Annual water withdrawal and consumption were projected to exceed 63.75 and 8.30 billion m 3 by 2030, up approximately 14% and 21% of those in 2015, respectively, if China does not implement any new water and energy policies. Replacing once-through cooling systems with closed-loop cooling systems would decrease national water withdrawal remarkably but increase water consumption. The west-centered spatial distribution of thermoelectric power generation would reduce water use at the national level; however, it will largely increase water stress in northern and northwestern China. Thus, relieving the stress of growing electricity demand on water resources in China requires comprehensive measures and quantitative estimates.
