A Visual Capitalist graphic published on September 24, 2026 compares the projected annual electricity use of three large proposed US data center campuses with the consumption of major American cities. The figures draw on 2026 corporate filings, SEC documents and city press offices.

Meta Hyperion in Richland Parish, Louisiana leads the comparison at an annual energy equivalent of 43.8 TWh. That is close to the 46.9 TWh forecast for New York City and nearly eight times the 5.6 TWh New Orleans used in 2025. The $50 billion project is expected to begin partial operation in 2030 and reach full build-out in 2032.

The AWS Susquehanna Data Campus in Pennsylvania is estimated at 16.8 TWh at full capacity, about 30 percent above Philadelphia's 13.1 TWh in 2022. The campus is expected to reach full ramp by 2032 as part of a $20 billion Amazon investment in Pennsylvania digital infrastructure, and roughly 40 percent of its power is planned to come from the Susquehanna nuclear plant.

Vantage Port Washington in Wisconsin is estimated at 11.4 TWh a year, about four times Madison's 2.8 TWh and comparable to Sacramento's 10.5 TWh. The $15 billion project is expected to finish in 2028 and forms part of the $500 billion Stargate initiative.

City benchmarks in the graphic run from 46.88 TWh for New York City to 17.50 TWh for Phoenix, 13.10 for Philadelphia, 10.51 for Sacramento, 5.60 for New Orleans and 2.80 for Madison.
