|NERC wind power cumulative capacity by interconnection by the end of 2012|
|Interconnection||Cumulative Capacity (MW)|
This site provides an overview of the current wind turbine fleet operating within North American Electric Reliability Corporation’s (NERC’s) regional reliability entities. In 2012 the US wind industry grew by 28% totaling in roughly 13,089 MW of newly installed wind power. This wind power has been installed across 45 states, with Texas (1,820 MW), California (1,625 MW), and Kansas (1,439 MW) being the states with the highest contribution.
With an average annual growth of 59.2% during the 2007-2012 period the U.S. wind industry finished 2012 with 60 GW of wind power capacity. Overall, the installed wind capacity in U.S. grew by 2427% since 1999.
The eight regional entities under NERC together with Hydro Quebec, Alaska Systems Coordinating Council (ASCC), and Hawaii came to 65 GW of installed wind capacity by the end of 2012. The Western Electricity Coordinating Council (WECC), Texas Reliability Entity (TRE) and Midwest Reliability Organization (MRO) have a combined wind capacity of over 44 GW or roughly 70% of all NERC wind power.
According to a DOE released report, manufacturers contributing to the North American wind market hail from United States, Europe, Japan, India, China, and South Korea. Altogether, twenty seven different WTG manufacturers supplied the market in 2012. The vendors with the largest share of the considered market, by the end of 2012, were GE Energy (38%), Siemens (20%), and Vestas (14%).
