One fifth of China's wind-generated power being wasted by state grid operators

State grid operators are wasting enough electricity to run Beijing for 40 days by intentionally delaying the hook-up of China’s wind farms and cutting back on purchases of wind power, Reuters reported, citing official data. In the first quarter of 2015 this strategy, known as curtailment, doubled from a year earlier to 10.7 billion kilowatt-hours, or roughly a fifth of total wind power generated in China. State grid operators are reluctant to connect wind farms in remote areas so long as their profit margins on renewable energy lag behind those of coal-generated power.
