The independence of the Texas electric grid — the interconnection now operated by ERCOT, which stays almost entirely within state lines and is largely untied from the Eastern and Western Interconnections — is commonly reported as a legal choice rather than a technical necessity. Per KUT/NPR's account, "electric providers in Texas had long maintained an informal agreement not to send power across state lines," and "the decision was made as a way to avoid federal regulation." The trigger cited is the 1935 Public Utility Holding Company Act (PUHCA), part of the New Deal regulatory expansion: utilities engaged in *interstate* transmission fell under federal jurisdiction, so keeping power inside Texas kept Texas utilities outside that reach.

This reframes a fact usually filed as cultural or engineering trivia ("Texas has its own grid") into an instance of durable regulatory arbitrage — a structural choice made for jurisdictional advantage and then defended over decades. The same isolation later had to be actively enforced, most sharply in the [[claim-1976-midnight-connection-texas-oklahoma-forced-jurisdiction|1976 "Midnight Connection"]], when a utility deliberately breached the intrastate boundary to try to force federal jurisdiction and regulators severed the link.

The point matters now because the isolated, distinctively-regulated Texas market is where AI data-center demand is concentrating fastest, driving [[claim-ercot-large-load-queue-quadrupled-2025-phantom-load|ERCOT's large-load interconnection queue to quadruple in a year]]. The AI buildout is not creating a new fault line so much as stress-testing one drawn in 1935. The national counterpart bottleneck — transmission interconnection running at [[claim-us-interconnection-queue-exceeds-installed-capacity|roughly twice installed capacity]] — is a generation-side queue; the Texas story adds the demand side and the regulatory geography underneath it.

> [!note] Seek's commentary:
> This is the cleanest "old idea hiding in new stakes" bridge in the capture: a 90-year-old jurisdictional dodge is now the substrate for the AI-power story. But it rests on one Austin public-radio piece, and the "avoid federal regulation" motive is exactly the kind of tidy origin story that gets flattened in retelling — hence the flag and the routed primary check. — Seek
