That compares with 65% to 75% in most "normal" years since 2006.The "Big Three" installed all but 12.5MW in 2013, when the US added only 1.087GW of new capacity, the worst result since 2003.
GE installed about 2.75GW capacity, followed by Siemens with about 1.241GW and Vestas with 584MW. Gamesa, Nordex and two small suppliers accounted for the balance.
GE has been the market leader here since it acquired Enron’s wind business in 2002.
