Yep. I believe in preparing for the worst and praying for the best.
We had a cold weather event maybe 3 or 4 years ago that affected my company (which is actually a freaking government agency, but I digress). Anyway, we were short on generation and a bunch of gas CT generators and combined cycle plants failed to start. The cold weather had uncovered the weaknesses - our weaknesses.
We didn’t quit get into the rolling blackouts, but we entered the EEA level 2, which is one step before that stage. People were out in droves thawing out things, getting the generators on line.
The lesson was learned - winterize the combined cycle and gas turbine plants.
Incidentally, one of the utilities in our reliability region actually will start and run at minimum output, all or most of their gas turbines when extreme cold weather was imminent. A good, but maybe more expensive, way of dealing with cold-related issues.
