In 2010, China became the largest wind energy provider worldwide, with the installed wind power capacity reaching 41.8 GW at the end of 2010, but about a quarter of this was not connected to the grid [REF].
In 2011, China put forth a plan to have 100 GW of grid-connected wind power capacity by the end of 2015 and to generate 190 terawatt-hours of wind power annually,[REF] and in 2014 it met its capacity target early [REF].
