Siemens Energy's Gas Turbine Backlog Hits 69 GW as Lead Times Stretch Past 3 Years

Siemens Energy’s gas turbine backlog reached 69 GW after the company booked 15 GW in new orders last quarter, Utility Dive reports, citing the company’s fiscal third-quarter earnings call.

Market Impact

Siemens Energy shipped 6 GW of turbines during the three months ending June 30, 2026, while sales from its gas services division jumped 62% year over year to €10 billion ($11.6 billion), CFO Maria Ferraro told analysts. Lead times across the company now run three years or more, according to Ferraro. CEO Christian Bruch said the company could deliver 15 to 16 GW of gas turbines this year after bringing roughly 30 additional units of medium-sized turbine manufacturing capacity online since 2025.

Siemens Energy currently operates about 35 units of large gas turbine manufacturing capacity and plans to add 15 more in 2027. On the medium-sized side, the company plans to expand from 80 units to about 100 units by 2028. It’s also planning a roughly 50% expansion of transformer and gas-insulated switchgear manufacturing capacity by 2030, a move tied to its Grid Technologies division’s €51 billion ($59 billion) order backlog. Bruch projected the addressable market for gas turbines could hit 120 GW a year, with about half of that demand coming from the United States, driven largely by data center buildout that has pushed other turbine applications further out on the calendar.

What It Means for Subcontractors

• Gas plant construction subs, including civil, E&I, and mechanical contractors, should secure schedule slots with EPCs and developers now. With turbine lead times running three-plus years, projects reaching FID today are already competing for equipment deliveries in 2029 and beyond.
• Firms bidding on switchgear and substation work should track Siemens Energy’s 50% transformer and gas-insulated switchgear capacity expansion through 2030, since grid-side subcontract packages tied to that buildout will likely open well before turbines ship.
• Expect continued U.S. demand concentration tied to data center power needs, per Bruch’s comments, which means field service companies in Texas and other data center corridors should prioritize relationships with developers locking in turbine allocations early rather than waiting for construction contracts to hit the street.
• Companies competing for large gas turbine installation work should note Siemens Energy’s plan to add 15 large-turbine manufacturing units in 2027, a signal that turbine availability, and the construction schedules tied to it, should loosen somewhat that year after the current capacity crunch.
• Wind-sector subcontractors should watch the Siemens Energy and Siemens Gamesa consolidation under the new Omterra brand, set to begin later this year, for potential shifts in procurement contacts and contract structures on offshore and onshore wind projects.
