Baker Hughes LM9000 aeroderivative gas turbine: 70.2-71.4 MWe at up to 43.1%, direct drive at 50/60 Hz, 36,000-hour supercore interval, DT70 mobile power.
The LM9000 is Baker Hughes' 70 MW-class aeroderivative gas turbine: 70.2 MWe at 42.8% for 50 Hz and 71.4 MWe at 43.1% for 60 Hz at the generator terminals, and 73.1 MW (98,029 hp) at 44.2% for mechanical drive, all at ISO conditions. Baker Hughes derives it from the GE90-115B aircraft engine and calls it "the most efficient gas turbine in the 65+ MW range".
The power turbine drives the generator directly at 3,000 or 3,600 rpm, so power-generation packages need no gearbox. A single annular combustor with dry low emissions is rated 15-25 ppm NOx without water. Inspections fall at 12,000 hours (borescope), 36,000 hours (supercore) and 72,000 hours (full engine). In mechanical drive the LM9000 can start a pressurized LNG compressor without a helper motor, per Baker Hughes.
In November 2025 Dynamis Power Solutions ordered LM9000s to build the DT70, a 70 MW mobile power unit, ten of them for 700 MW of oil and gas power, as part of a 25-turbine, 1.3 GW aeroderivative order. The LM9000 sits between the LM6000 (about 50-57 MW) and the intercooled LMS100 (about 108-113 MW) in output; it is gas-only today, with dual fuel in development per Baker Hughes' 2025 overview.
Why it matters
At 43.1% (60 Hz) at the generator terminals and with direct drive, the LM9000 matches the intercooled LMS100PB+ (43% per Baker Hughes) in simple-cycle efficiency at about two-thirds of the output, without water for NOx control and with a 36,000-hour supercore interval. Assessment: its constraints for power projects are gas-only fuel today, up to 5% hydrogen, and a young fleet with little published operating history.
Who buys it
LNG developers using it as a refrigeration-compressor driver, mobile and distributed power providers (Dynamis Power Solutions' DT70), and simple-cycle, cogeneration and combined-cycle power developers that want about 70 MW per unit at aeroderivative efficiency. Baker Hughes lists onshore and offshore LNG, pipelines, industrial use and combined-cycle plants as applications.
Role in the data center
Assessment: a 70 MW behind-the-meter block, two to four units per 150-300 MW phase plus a spare, at about 43% simple-cycle efficiency without water, or the gas turbine in a combined-cycle block (Baker Hughes claims 56% in cogeneration). Mobile DT70 units bring the same engine on a relocatable package. Baker Hughes publishes no start-to-load time for the LM9000, so confirm start and black-start capability per package.

Technical summary
Baker Hughes rates the LM9000 at 70.2 MWe and 42.8% (50 Hz) and 71.4 MWe and 43.1% (60 Hz) at the generator terminals, and 73.1 MW (98,029 hp) at 44.2% for mechanical drive, at ISO conditions (natural gas, 15 C, sea level, 60% relative humidity, no inlet or exhaust losses). NOx is 15-25 ppm and exhaust temperature 456 C (455 C in mechanical drive). Power generation runs at 3,000 or 3,600 rpm direct drive. Inspections fall at 12,000, 36,000 and 72,000 hours. The package measures 13.3 x 5 x 18.2 m and the 2025 overview lists 77 tons. Fuel is gas only, 36-55 modified Wobbe index, with up to 5% hydrogen. Heat rate calculated from 43.1% is about 7,917 Btu/kWh LHV.
Major variations
Baker Hughes sells the LM9000 in power-generation packages for 50 Hz (70.2 MWe) and 60 Hz (71.4 MWe), both direct drive, and in a mechanical-drive package (73.1 MW shaft) for compressors such as LNG refrigeration trains. Dual fuel (gas plus liquid) is in development per the 2025 overview. Dynamis Power Solutions' DT70 packages one LM9000 as a 70 MW mobile unit. The LM9000 is a different engine from the LM6000 and the intercooled LMS100.
Configurations and options
Baker Hughes supplies a modular package for faster installation, measuring 13.3 x 5 x 18.2 m. Options that change price or lead time are the frequency (50 or 60 Hz generator), the NOx level within 15-25 ppm, simple-cycle, cogeneration or combined-cycle scope, mobile packaging by a packager, and the service agreement covering supercore and full-engine exchanges.
Compatibility and dependencies
Fuel is natural gas only, within a 36-55 modified Wobbe index and up to 5% hydrogen; sites needing liquid backup fuel have no LM9000 option until the dual-fuel system is released. Direct drive at 3,000 or 3,600 rpm fixes the generator frequency to the package. Confirm the fuel-gas supply pressure requirement and any compression against the package datasheet.
Planning price band
Modelled planning estimate: $1.05M–$2.20M/MW · $1,050–$2,200/kW · $74.97M–$157.08M per unit (LM9000, 60 Hz, 71.4 MW; New OEM; very low confidence; gt-planning-v3, as of 2026-11-03). Not a quote or an observed sale price. New OEM gas turbine generator package, equipment scope. Inclusions and delivery terms vary by offer and are subject to confirmation. Not a project budget: EPC, BOP, installation and financing sit outside this band.
Newest large aero; no used fleet.
What drives the price
Power-generation frequency or mechanical-drive package; simple-cycle, cogeneration or combined-cycle scope; mobile packaging; the NOx level; service agreement terms including spare supercore access; the delivery slot; and, for used units, hours, starts and supercore inspection status.
Lifecycle and maintenance
Baker Hughes rates borescope inspection at 12,000 hours, supercore inspection at 36,000 hours and full-engine inspection at 72,000 hours. The supercore can be exchanged rather than overhauled in place, which shortens outages where a spare core is available. Baker Hughes does not publish an MTBF figure or an LM9000 fleet count as of October 2026.
Thermal and emissions profile
The single annular dry-low-emissions combustor is rated 15-25 ppm NOx without water injection, which Baker Hughes notes eliminates water use for emissions abatement. Fuel is gas only with up to 5% hydrogen by volume per the 2025 overview.
Common failure points
- Hot section (supercore) — Coating loss, oxidation or cracking found at borescope or supercore inspection
- DLE combustor — Combustion dynamics or emissions drift
- Power turbine and bearings — Blade distress, bearing wear or rising vibration
- Generator — Insulation ageing or cooling faults
LM9000 ratings at 50 and 60 Hz
- Baker Hughes rates the LM9000 at 70.2 MWe (42.8%) for 50 Hz and 71.4 MWe (43.1%) for 60 Hz at the generator terminals, ISO conditions with no inlet or exhaust losses. Request site-corrected output with the inlet, exhaust and auxiliary losses of the offered package.
- The power turbine drives the generator directly at 3,000 or 3,600 rpm, so the frequency is fixed by the package rather than a gearbox.
Fuel and emissions
- The LM9000 is gas-only today, with dual fuel in development per Baker Hughes' 2025 overview, and up to 5% hydrogen. Sites that need liquid backup fuel should plan for another model or confirm the dual-fuel release date.
- The dry-low-emissions combustor is rated 15-25 ppm NOx without water. A new US installation falls in the medium band of NSPS Subpart KKKKa (15 ppm at high utilization, 25 ppm at low utilization).
Maintenance and availability
- Baker Hughes rates borescope inspection at 12,000 hours, supercore inspection at 36,000 hours and full-engine inspection at 72,000 hours. Confirm whether the service agreement includes access to a spare supercore.

What is the Dynamis DT70?
A 70 MW mobile power unit that Dynamis Power Solutions builds on one LM9000. In November 2025 Dynamis ordered ten LM9000s for 700 MW of DT70 units as part of a 25-turbine, 1.3 GW order from Baker Hughes.
What are the LM9000 maintenance intervals?
Baker Hughes rates borescope inspection at 12,000 hours, supercore inspection at 36,000 hours and full-engine inspection at 72,000 hours.
Inspection checklist
Confirm the engine and power-turbine serial numbers and the package type from the nameplates. Obtain operating hours, starts and trip history. Review borescope reports against the 12,000-hour interval and the status of the 36,000-hour supercore inspection. Confirm the NOx rating and DLE tuning records. Check generator test results and vibration trends, controls software licences and the service agreement, including access to a spare supercore. Agree acceptance criteria before payment.
Procurement channels
Assessment: used LM9000 units are rare because the fleet is young.
Regional notes
Separate 50 Hz (70.2 MWe) and 60 Hz (71.4 MWe) ratings apply, both direct drive. In the United States a new LM9000 falls in the medium band of NSPS Subpart KKKKa (about 565 MMBtu/h LHV and 626 MMBtu/h HHV at ISO, calculated). Baker Hughes lists onshore and offshore LNG, export terminals and pipelines among its applications.
