Why it matters: ERCOT — the grid operator for most of Texas — now runs on a mix that would have been unrecognizable a decade ago. Wind has led the state's generation mix for years, and solar and battery storage have scaled up fast enough to be setting their own grid records in 2026.

Wind, solar, and demand records aren't spread across separate years — three of these five were set within the same five weeks of summer 2026, as record heat drove record demand and record renewable output at the same time.
