AI Data Center Power Constraints Are the Real 2026 Bottleneck
In 2024, the scarce resource in AI infrastructure was H100 supply. In 2026, it is the grid connection to power those GPUs. Gartner projects 40% of AI data centers will be power-constrained by 2027, and approval timelines for new grid capacity in major US and European markets now run 24-36 months.

Opening excerpt (first ~120 words) tap to expand
In 2024, the scarce resource in AI infrastructure was H100 supply. In 2026, it is the grid connection to power those GPUs. Gartner projects 40% of AI data centers will be power-constrained by 2027, and approval timelines for new grid capacity in major US and European markets now run 24-36 months. The hardware problem has started to ease. The power problem has not.The Shift from GPU Shortage to Power ShortageFor most of 2023 and 2024, the conversation was about CoWoS packaging capacity at TSMC and HBM supply from SK Hynix. Long procurement queues, chip shortages, and limited H100 availability meant teams were constrained by hardware access, not by where to plug it in.
