AI data centers are driving the expansion of the US power grid. The AI computing infrastructure boom has shifted from chips to electricity, and the hard bottleneck of grid equipment is an industry consensus, with a $75 billion transmission expansion underway. On the demand side, US electricity consumption is projected to increase from 4,097 TWh in 2024 to 4,283 TWh in 2026, with growth led by the commercial and industrial sectors (primarily data centers). US data center capacity is expected to reach 120 GW by 2030, approximately five times that of 2025. Tech giants have signed electricity ratepayer protection commitments, locking in demand for power infrastructure. On the supply side, 765 kV ultra-high voltage transmission grid construction...
