Lowering China's coal-fired power overcapacity can save water for 27 mn

Urging China to cut down on its "severe" coal power overcapacity, a report on Wednesday said this could save enough water to meet annual needs of 27 million people in water-stressed areas.

The report by Greenpeace East Asia said that despite reduction in coal powered plants since 2014, the Chinese coal-fired capacity in areas of high water stress continues to increase.

However, China's per capita water resources amount to only one-third of the global average. According to the report, by 2020, more than 60 per cent of the coal power industry's water consumption is projected to take place in areas of high water stress.

China is the world's largest coal consumer, Greenpeace said.

The report also recommends that both the coal power overcapacity and water stress problems be resolved by optimising water saving in the 162 provinces.

"The proposed plan could reduce water consumption in the coal power sector by up to 500 million cubic metres in 2020 in high water-stressed areas," the report stated.

Greenpeace stated that if the expansion goes unabated, the coal power capacity in water stressed areas is projected to jump from 437 GW in 2016 to 527 GW in 2020.

It thus urged that China reduce its coal-fired capacity by retiring plants in areas of high water stress and halting the planning and construction of new coal-fired power plants.

"Targeted capacity cuts in regions with high water stress would free up water for human consumption and economically productive uses," said senior global coal campaigner Lauri Myllyvirta.
