Here in Iowa and the midwest, we received even colder temps, down in the -20 to -30's and we have wind turbines also but they didn't have issues with freezing so wondering why the turbines in TX did? I pray for those in TX right now as I know what it feels like to be cold all the time. My neighbors spend winters in TX. Just texted them to see if they are okay but haven't heard from them yet. I know my nephews down in Waco have had problems.
