Data center power delivery has become the hard constraint on AI expansion, not semiconductor manufacturing. Abilene's $20 billion Lantana power project typifies how utilities and grid infrastructure now limit GPU cluster placement. The bottleneck has shifted from Silicon Valley's chip design cycle to Texas utility politics and transmission line permitting, where 18-month Environmental Impact Statements matter more than TSMC's fab capacity. Cloud giants are scrambling to secure nuclear power contracts. Grid operators, not OpenAI, effectively control the pace of model training.
