①
Power has become the binding constraint on AI capex growth
Oracle has invoked force majeure on multiple AI data center projects due to power supply delays; the Federal Energy Regulatory Commission (FERC) is taking an interventionist stance to accelerate interconnection queues; and the U.S. Department of Energy is investing $1.9 billion in advanced transmission projects to add 23 gigawatts of capacity. A new analysis warns that buildout delays and interconnection backlogs are threatening the pace of AI infrastructure expansion.
