PA gets weather like Texas is experiencing now every winter from November through March. Why don't the wind turbines fail there?

From what I am aware of there aren't very many wind turbines in Pennsylvania. A quick look on the DEP website tells me there are only 27 wind farms in the entire state, contributing 1300 megawatts of power (only 3% of PA power supply comes from the Other Renewables category which includes wind, solar, geothermal, and biofuel).

For comparison, Pennsylvania has just 5 active nuclear power plants which provide  39% of the total power for the state. The most abundant source is natural gas, which accounts for 47% of the total power output for the state. So if the wind turbines locked up in the winter we would probably not even notice since it is such a miniscule part of our energy infrastructure.

Texas, on the other hand, gets 24% of their energy from wind turbines. So when they fail it is much more noticeable and their other sources can't meet the demand in order to compensate.

What wind turbines, we have coal.

Texas sought to save money by making their own grid so as to avoid federal regulations. Their cheapness caught up to them and they came running to the rest of the country to bail them out. Next time, maybe they'll bury their natural gas pipelines deeper. It wasn't just the wind turbines that failed; they are a small part of Texas' energy supply.

maybe theyre used to it so they made them better

Texas was not prepared for the weather, the power company made zero preps.

And wind turbine failure was a small part of the failure.
