Ever wonder why TX has to do things like rolling blackouts during extreme weather? The answer is because we’re the ONLY state that has isolated our power grid from the rest of the country in order to avoid Federal regulation! https://www.texastribune.org/2011/02/08/texplainer-why-does-texas-have-its-own-power-grid/
“Texas' secessionist inclinations do have one modern outlet: the electric grid. There are three grids in the Lower 48 states: the Eastern Interconnection, the Western Interconnection — and Texas.”
Like most things that seem like “just the way it is,” this is an intentional and politically-motivated choice by our elected officials. When your house hits 50 inside today, be sure to thank an anti-regulation Republican lawmaker.
