Caterpillar and Cummins race to add gas turbine capacity as US orders hit 20 GW in Q1
US power equipment makers are scrambling to expand output as AI data center demand outpaces regulated utility supply additions.
US companies placed orders for roughly 20 GW of gas turbine generation capacity in the first quarter of this year, according to the International Energy Agency, forcing manufacturers including Caterpillar and Cummins to accelerate factory expansion plans. One company chief executive said production capacity was being boosted by 30 percent, but conceded that "that's not enough to meet growing demand."5
The equipment squeeze is now the binding constraint on US power supply. Bank of America analysts forecast the United States will need more than 230 GW of new generating capacity over the next five years, yet regulated utilities are expected to add only about 93 GW of accredited supply, leaving a gap of more than 100 GW.7
The IEA data show the scale of the pivot. As much as 40 percent of new gas turbine orders came from the United States, with another 35 percent from Europe. US companies are set to spend some $50 billion on power generation from coal and natural gas this year, the IEA said, the first time in decades that American spending on those two fuels would exceed China's, with the difference at $3 billion.5
Manufacturers are responding. Caterpillar, INNIO, Rolls-Royce and Wärtsilä have all expanded production to meet rising demand, BofA analysts said, with the oilfield service sector also pushing in. SLB and Liberty Energy announced a strategic alliance on July 16 (2026-07-16) to deliver modular infrastructure and integrated power generation solutions for new data center projects globally.6,7
The demand driver is the AI buildout colliding with a power system that cannot keep pace. BloombergNEF has found that the data center expansion required to support artificial intelligence will keep fossil fuels in use for longer, making AI-driven electricity demand a key new source of load growth into the coming decade.2
The gap between what utilities can deliver and what data centers need is pushing developers toward behind-the-meter generation, BofA said. The analysts expect more data center developers to turn to that route as utilities struggle to bring capacity online quickly enough.7
There is a wrinkle in the supply math. Planned generation additions may overstate available supply because intermittent resources such as wind and solar contribute less accredited capacity during peak demand than their nameplate ratings suggest, BofA noted. That tilts the economics toward dispatchable gas-fired units that can guarantee power around the clock.7
Battery storage companies are trying to capture some of the same demand, but face lengthy grid connection queues and a supply chain heavily dependent on China, Reuters reported on May 18 (2026-05-18). That leaves gas turbines as the near-term winner for hyperscalers needing firm power on short timelines.3
The market is rewarding the exposure. Fluence Energy, a battery storage provider, closed at $24.16 on May 8 (2026-05-08), up 98.2 percent in a single week after disclosing master supply agreements with two hyperscalers and a record $5.6 billion backlog. But shares remain down roughly 39 percent year to date, a reminder that the AI power trade has been volatile.1
Not all the action is in gas. Quick Read Capital said capital is rotating into energy companies that can supply power for AI data center buildouts, with nuclear and renewable baseload generation offering the cleanest solutions to address constraints.1
The IEA numbers suggest the equipment makers are the cleanest read-through for the trend. A 20 GW order book in a single quarter implies a multi-year production backlog, and the CEO comments about capacity plans undershooting demand point to pricing power for turbine suppliers.5
The unresolved risk is interconnection and permitting. Grid queues and approval processes could slow even the gas buildout, and regulators are being pushed to encourage architectures that reduce stress on local infrastructure by cutting demand spikes before adding new load. If those frictions bind, the 100 GW gap BofA identified could widen further.4,7
Watch the next quarterly order figures. If Q2 gas turbine orders approach the Q1 pace of 20 GW, the production capacity constraints will tighten further and the scramble among Caterpillar, Cummins and their rivals will intensify.5
