So Texans had a very interesting week last month. It got colder in Texas than it has been since nearly 1989. We got a few inches of snow and temperatures in the teens in Houston. Austin reached single digits! These unprecedented conditions created a very unique situation.
I had gone snow skiing 3 weeks prior and my gear was still handy so I put it on and went for a stroll early in the morning.
The entire Texas power grid nearly collapsed as the storm rolled through. In the graph below you can see where demand outstripped supply.
This graph was captured off of the ERCOT website at roughly February 15th at roughly 5 pm. Apparently many of Texas's power plants were unprepared for this storm. Generation capacity went down and demand went up so many homes had their power cut off for several days.
(this is a sub-panel and I turned off the main breaker's connection to the grid. The breaker was cannibalized from the dishwasher and sink disposal)
