China’s coal-fired power plants – many of them state-owned – may start losing money from next year because of overcapacity, electricity pricing reforms and tighter environmental constraints, according to a Greenpeace study. The South China Morning Post reports the warning comes as the country’s top economic planner said on Monday that the government would curb power output from burning coal over the next three years to reduce excess capacity and fight air pollution. The National Development and Reform Commission also said it would set up a risk-assessment system to measure power production efficiency. However, 210 coal-fired power plants were approved in 2015 alone.
