I live in Texas. I didn't have power for 3 days. It got down to 35 degrees inside my house.
Why did the grid fail? It sure wasn't because the 'turbines' locked up. First you need to know that the Texas power grid is deregulated. What does that mean? It's a haphazard hodpodge of companies. There are the retail billing companies (who the consumer buys through). Then there are the transmission companies. They handle moving power from the plants to the consumer. And then there are the power production companies. They just make the power, and hand it off to the transmission companies.
It's all 'managed' by ERCOT.
It's important that you remember that.
The "wind turbines freezing up" did not cause the massive blackout in Texas. It happened because
1) Most of the Texas power grid is separated from the national power grid, which means it can't 'buy power' from other out-of-state providers. (This isn't state wide, just most of the state).
2) it's deregulated, so there's no incentive for power supply companies to upgrade their equipment. They pay the least amount to fix a system that is seconds away from breaking down at any moment.
3) This aging and barely held together system sits outside, which means it's mostly built to handle weather common to Texas. You know, heat. (but not heat like we get today. Like hot summers from the 60s which was the mid-90s). When that cold weather rolled in, demand went way up and that aging system started to fail. It couldn't handle the demand and it couldn't handle the cold. So ERCOTturned parts of it off to keep it from frying out.
4) Which means ERCOT cut power to the transmission companies (yes, the companies handling the transmission of power lost power).
5) because the transmission companies shut down, the natural gas power plants also shut down. Because it takes electricity to turn gas into power. (no, they don't run on their own power. I don't make the system, I just have to live in it).
