Data centers drive ~101GW of US on-site gas, lifting plant costs 66%
Developers bypass grid queues with behind-the-meter gas: a 7.7GW West Texas permit, NextEra's 10GW, an Oracle–Bloom 2.8GW fuel-cell deal, and GE Vernova's 100GW turbine backlog
Summary
To dodge multi-year grid-interconnection queues, data-center developers have announced roughly 101GW of on-site (behind-the-meter) natural-gas generation in the US. Pacifico Energy's GW Ranch in West Texas won an air permit for up to 7.7GW (Jan 2026); NextEra secured approval for two plants totalling ~10GW in Texas and Pennsylvania (May 2026); and an Oracle–Bloom Energy fuel-cell deal hit 2.8GW, the largest single on-site supply agreement on record. GE Vernova's gas-turbine backlog stands near 100GW. The demand surge has driven gas-plant costs up ~66%. The US now leads the world in new gas-power development, the fossil counterpart to the nuclear order book and the grid-price strain.
By the numbers
- ~101GW, announced US on-site gas generation for data centers.
- 7.7GW, Pacifico GW Ranch (West Texas) air permit.
- ~10GW, NextEra's two approved plants (Texas + Pennsylvania).
- 2.8GW, Oracle–Bloom fuel-cell deal (largest on-site supply agreement).
- ~66% / ~100GW, rise in gas-plant costs / GE Vernova turbine backlog.
Why it matters
The AI buildout is reindustrialising US power around private, gas-fired "campuses" that bypass the public grid, locking in decades of fossil capacity, repricing turbines, and shifting where energy infrastructure gets built and who controls it.
What to watch
- Turbine delivery timelines against GE Vernova's ~100GW backlog.
- Air-permit and emissions challenges to behind-the-meter gas.
- Whether on-site gas eases or worsens public-grid prices (vs PJM).
