Energy usage is superlinear below a certain point. As I recall, about 25% of homes in Texas use heat pumps. but below 30-ish degrees, heat pumps don't work and they have to switch to resistance-based heating So, demand will start rising a whole lot faster.

There are newer heat pumps that work below 30 degrees, but they're more expensive and not typically used in Texas for obvious reasons.
