America’s AI ambitions are colliding with a creaking electricity grid. The 102-mile Cardinal-Hickory Creek transmission line, built to carry wind power from Iowa to Wisconsin, took 13 years to complete due to regulatory fights, wildlife refuge disputes, and conflicting state and federal rules. Completed only in 2024, the project exemplifies how infrastructure delays are undermining national strategy.
As hyperscalers like Amazon, Google, Meta, Microsoft, and Oracle prepare to spend an estimated $900bn on AI data centres this year, the grid’s inability to deliver power efficiently becomes a critical bottleneck. Demand is projected to surge by 166 gigawatts by 2030 — equivalent to 15 New York Cities. While generation capacity is expanding, transmission remains the weak link.
Much of the US network dates to the 1960s and 1970s, and new high-voltage line construction has plummeted from 4,000 miles in 2013 to under 900 in 2024. Projects now take a decade or more to develop, twice as long as in previous decades. Without urgent reform, the infrastructure gap may strangle the AI revolution before it fully begins.
