According to a New York Times report from February 15, winter storms are causing significant disruption to electrical service across the state of Texas, partially due to frozen wind turbines across West Texas. "Roughly half of the state's wind generating capacity was knocked offline, shutting off as much as 10,500 megawatts (MW) of wind power," the article says.
Authorities implemented rolling blackouts to help conserve power, an action that hasn't happened in wintertime since February 2011, the article reports.
