Absolutely: ERCOT's battery storage is worldbest.

As a fifth-generation former Texan, I understand "separatist mentality." ERCOT's buy/sell market is perhaps also the most purely capitalistic marketplace in existance (and among least-regulated, in first-world); for these reasons, winter-proofing funding is terrible and outages likely when the system is stressed (e.g. approximately every decade Texas loses power during winter storms) — which is also when generating profits are maximized (orders of magnitude increases).

Certain deregulated-market Texans are still paying off powerbills from years-old storms, a few cold days of billing often exceeding the rest of the year's usage.
