GE Vernova 7F.05 / 7HA

201-430 MW heavy-duty 60 Hz frames anchoring combined-cycle plants and data center campus generation

GE Vernova 7F.05 / 7HA is one of 21 gas turbines tracked in the SecondWatt catalogue, each with specifications, lead times and indicative secondary-market pricing.

GE Vernova 7F and 7HA frame gas turbines: 201-430 MW ratings, verified specs, plant-level market valuations, rotor life limits, and inspection guidance.

The GE 7F and 7HA are 60 Hz heavy-duty frame gas turbines. The 7F family, in service since 1990, spans 201 MW (7F.04) to 239 MW (7F.05) simple cycle with more than 950 installed units producing about 175 GW across 11 countries. The 7HA H-class successor spans 290 MW (7HA.01) to 430 MW (7HA.03) with combined-cycle efficiency to 64%, and GE reports more than 200 H-class units ordered with 4 million fleet operating hours. These frames anchor utility combined-cycle plants and, increasingly, dedicated data center generation: Homer City in Pennsylvania is deploying seven 7HA.02 units for a 4.5 GW data center campus. The 7F fleet is the aftermarket workhorse, with Advanced Gas Path upgrades adding up to 23 MW and extending hot-gas-path intervals to 32,000 factored fired hours. Complete units rarely list publicly. Two never-installed 2002-2003 7FA units are brokered price-on-request, an 81 MW 7EA sold through Phoenix Equipment, and most F-class capacity changes hands inside whole-plant acquisitions that Enverus values at roughly 1.0 million USD per MW on average in 2025, double the pre-2025 level. H-class units and delivery slots have no observed public resale.

Why it matters

GE reservations are effectively sold out through 2030 with a 116 GW backlog, so operating F-class capacity has repriced: gas plant M&A doubled to about 1.0 million USD per MW in 2025 and top PJM assets approach 1.9 million USD per MW. Meanwhile many 7FA rotors from the 1998-2001 build bubble are hitting their 144,000 factored-hour end of life, feeding rotor and parts demand.

Who buys it

Utilities and IPPs buy F-class plants for baseload and capacity markets; data center developers and hyperscalers now acquire the same plants for campus power, as at Homer City. Buyers of loose 7F units are repowering developers and operators hunting rotors, cores, and AGP-upgradable machines. The trigger is the 2030-2031 new-unit queue and rising slot pricing.

Role in the data center

Dedicated campus generation at 300 MW to multi-GW scale: one to seven units in combined cycle behind the meter, as configured at the Homer City 4.5 GW campus.

Configurations and options

F-class units on the market appear as complete combined-cycle blocks with HRSG, steam turbine, and SCR, or as loose gas turbine generators from cancelled projects. Key optioning: AGP status, DLN 2.6 generation, Mark V/VI/VIe controls, hydrogen-cooled 7FH2 generators, and dual-fuel capability.

Compatibility and dependencies

Single-shaft 60 Hz machines requiring heavy foundations, high-pressure fuel gas, and plant-integrated controls. Combined-cycle duty pairs with an HRSG and steam turbine sized per block; SCR with ammonia systems is standard on new permits. Rotor life accounting per GE TIL-1576 and GER-3620 governs remaining-life valuation.

Pricing and availability

Trend: up Effective pricing shows through plant M&A: gas plant acquisition multiples ran about 0.5 million USD per MW before 2025, doubled to about 1.0 million USD per MW in 2025 per Enverus, and Talen paid about 1,205 USD per kW for two 7HA.02 plants in July 2025. New-order slot pricing rose another 10-20 USD/kW-class points in H1 2026 per GE earnings coverage. Lead time, new: 48-72 months. Lead time, used or refurbished: 6-18 months. Warranty, used: As-is; certified pre-owned rotors carry vendor terms.

Lifecycle and maintenance

7F hot-gas-path intervals run 10,000-32,000 factored fired hours depending on AGP package and duty; rotor end of life is 144,000 FFH or 5,000 factored starts under GE TIL-1576 methodology. AGP installs complete in 11-18 days and over half the 7F fleet has them. 7HA.03 combustion and HGP inspections run under 22 days and majors under 29 days per GE. Aftermarket rotors, cores, and certified pre-owned hardware trade through EthosEnergy, MD&A, and PSM.

Common failure points

• R0 compressor blades — High-cycle fatigue cracking and liberation after leading-edge erosion
• Rotor (life-limited) — End-of-life at 144,000 FFH or 5,000 FFS; 1998-2001 bubble units aging out
• DLN 2.6+ effusion plates — Cracking near 3,000 operating hours; nozzle tip cracks
• S5 stator roots — Corrosion-pitting cracks with tip rubs and FOD contribution
• H-class stage 1 blades (7HA) — Oxidation issue forced 2018 shutdowns at Colorado Bend
• T-fairings and VSV2 — Wear driven by turning-gear hours and cycling

Inspection checklist

Rotor life — audit factored fired hours and starts against the 144,000 FFH / 5,000 FFS end-of-life limits; a rotor within 20,000 FFH of limit prices as a rotor-replacement candidate R0 compressor blades — inspect leading edges for erosion from fogging and water washing; blend or reject beyond 0.010 inch material loss S5 stator roots — borescope for corrosion-pitting cracks and tip-rub evidence documented across the 7F fleet S17 stator row — check for wear and vane migration per fleet TIL history VSV2 airfoils — verify tip condition per TIL-2167; record any tip loss T-fairings — inspect wear per TIL-2122 and log turning-gear hours, a key wear contributor AGP S3B buckets — check tip shrouds for creep deflection per TIL-2045 on AGP-equipped units DLN 2.6+ hardware — inspect effusion plates for cracking reported near 3,000 operating hours and center fuel nozzle tips Hot gas path position — reconcile hours and starts against the applicable interval (up to 32,000 FFH with AGP Tech hardware) Combustion dynamics — review tuning records across ambient range; require dynamics data from the last 12 months of operation Generator (7FH2) — hydrogen seal integrity, capability curve test records, and stator insulation resistance at or above 100 megohms Controls — identify Mark V/VI/VIe generation and confirm cybersecurity and spares support status Emissions train — verify SCR catalyst age and ammonia slip below the permit line (5.0 ppmvd at the Homer City precedent) Records — require complete TIL compliance log, borescope history, and outage reports for the last two inspection cycles Performance test — ISO-corrected output within 5% of rating and heat rate within 3% of the applicable fact-sheet value at base load

Procurement channels

Whole-plant M&A is the dominant channel, brokered by banks and advisors rather than listings. Loose units and rotors trade through specialist brokers (SirGen, RMA Global, Phoenix Equipment) and aftermarket houses (EthosEnergy, MD&A, PSM). H-class slots move only through OEM reservation agreements with non-refundable deposits.

Regional notes

60 Hz only; the fleet concentrates in North America with additional units in Asia and the Middle East. US capacity is the epicenter of data center-driven plant M&A, and no 7HA units have appeared on any public resale channel to date.
