Gas Turbine Shortage Caps US Data Center Power as PJM Spot Hits $73
GE Vernova's 20 GW annual global output is shared across utilities, Middle East projects and AI developers, leaving hyperscalers rationing scarce equipment.
PJM Western Hub real-time spot power was trading at $73.72 per megawatt-hour on Monday (2026-08-31), as analysts and developers warned that the turbines needed to serve surging data center load are already committed to competing buyers across the globe.7,6
GE Vernova, the dominant Western supplier of large gas turbines, produces roughly 20 gigawatts of capacity per year for all customers worldwide, according to OilPrice.com reporting from August 22 (2026-08-22). Only about a fifth of that annual output is designated for data centers. The rest flows to utilities retiring coal plants, Middle East power and desalination projects, and industrial grid reliability — customers with long-standing order positions and fewer alternatives.5
AI developers and power companies betting on gas turbines to backstop US data center load are effectively competing in the same constrained queue. Manufacturers of turbines, transformers, switchgear and cooling systems are fielding new orders as power demand projections climb, economies.com reported on August 27 (2026-08-27). But equipment lead times are already measured in years, and the pipeline of buyers is global.7
The cost signal is building. Wood Mackenzie forecasts turbine prices alone will reach $600 per kilowatt by end-2027, a 195% jump from 2019 levels, OilPrice.com reported. That trajectory will compound project economics already strained by interconnection delays.5
PJM's recent clearance of a large tranche of new generation through its interconnection queue, reported by Canary Media on August 24 (2026-08-24), represents a meaningful shift after years of backlogs. But the queue delay had already extracted a toll. Developers interviewed for a 2024 PJM interconnection study had suspended all permitting, siting and equipment procurement work while waiting for queue outcomes, according to researcher Silverman cited by Canary Media. That pause widened the gap between approved capacity and equipment on order.6
The Federal Energy Regulatory Commission ordered PJM to allow virtual power plants to compete in its wholesale market, Canary Media reported on August 13 (2026-08-13), opening demand-response and distributed resources to help meet load. Aggregated distributed assets can reduce peak demand, but they cannot replace dispatchable gas turbines for baseload data center supply.4
NYMEX Henry Hub front-month gas was at $2.91 per MMBtu on Monday (2026-08-31), up 1.39% on the session, suggesting the fuel market has not priced the equipment constraint. Analyst Matt Smith has forecast US natural gas storage exhaustion by 2030 as AI data center demand and LNG export growth simultaneously drain domestic supply, with electricity consumers absorbing the cost through power bills.3
A 4-to-6 gigawatt data center complex consumes roughly 1 billion cubic feet per day of natural gas depending on turbine efficiency, Atlantic Council analysis shows, a draw comparable to a mid-sized LNG export terminal. The fuel demand from any single facility is manageable. The cumulative demand for turbines across dozens of planned projects is not.1
Some AI developers have explored operating data centers as flexible grid assets, curtailing inference operations during peak demand periods, the Atlantic Council noted. That approach would reduce the effective turbine capacity required per unit of compute. It also complicates the business case for hyperscalers whose customers expect continuous inference availability.1
The Southeast Asian experience shows what turbine scarcity does to power buildout timelines. Wood Mackenzie data show only 11 gigawatts of Southeast Asia's planned gas-power pipeline has secured turbines, with WoodMac projecting just 14.9 GW, roughly a third of planned targets, entering service by end of this decade. Indonesia has locked in supply for only 200 megawatts of a planned 8.4 gigawatt pipeline. Vietnam faces the widest shortfall: only 3.7 gigawatts of a 29.4 gigawatt government target is likely to reach operations by 2030.2
US hyperscalers are better capitalized and closer to existing supply chains than Southeast Asian utilities. They are competing for the same finite annual production from the same handful of manufacturers. Wood Mackenzie's turbine price forecast of $600 per kilowatt by end-2027 is the figure to watch: if realized, it will force project re-underwriting across PJM's newly cleared interconnection queue at exactly the moment developers planned to begin construction.5,6
