China Learning The Economics Of Wind The Hard Way

Ye Qi, Jiaqi Lu, and Mengye ZhuThursday, March 1, 2018 (Brookings Institution)
“…China has successfully fertilized the [world’s] biggest renewable industry in terms of both installation and equipment manufacturing…[Its investment in renewables is 100 times higher than it was in 2005] and accounts for one-third of global investments in renewable energy today. China aims to boost its wind power installation to 250 gigawatts and solar to 150 gigawatts by 2020…[But curtailment of renewable electricity generation is becoming increasingly common.] From 2010 to 2016, 150.4 million megawatt hours, or as much as 16 percent of overall wind generation, was abandoned. Over the last 6 years, the opportunity cost of wind power curtailment in China is estimated to exceed $1.2 billion…[and] about 1.5 percent of China’s total emissions in 2016…Direct causes for curtailment change over time and across different provinces…[F]rom 2010 to 2012, the main causes of curtailment were the rapid growth of installation and inadequate buildup of transmission grid…[After new grid construction in 2013 and 2014, curtailment was caused when demand for electric power was slowed down due mainly to economic deceleration…” click here for more
