SelnovixIdle and stranded plants
Gas-fired plants that stopped running when fuel supply or tariffs no longer worked.
Existing turbines. New possibilities for power.
We source and assess gas turbines and generation assets for acquisition, refurbishment and redeployment, with a special focus on older and idle units that can return to service sooner than new equipment. Each unit is evaluated against the requirements of its next project.

A special focus on older gas turbines.
Many capable turbines are sitting unused: in plants that lost their fuel supply, in units held in long-term preservation and at sites being retired or sold. While new units carry long manufacturing lead times, a well-documented older turbine can be the faster route to firm power.
- Earlier availabilityAn existing unit can shorten the path to power when new equipment carries long lead times.
- Measurable conditionRunning hours, starts and inspection records show condition rather than assume it.
- Established designsWidely used turbine models have known maintenance practices, parts and service options.
- RedeployableTurbine and generator packages can be dismantled, refurbished and moved to a new site.
Where older turbines are found.
We look wherever reliable generation equipment sits unused, including India’s idle gas-based plants and international markets.
Mothballed units
Turbines held in long-term preservation, with layup and maintenance records.
Retiring and repowering sites
Units released as owners retire, repower or restructure their fleets.
Insolvency and asset sales
Equipment offered through lender-led, court-supervised or auction processes.
Surplus and spare inventory
Uninstalled units, spare engines and packages from fleets and projects.
Combined-cycle blocks
Gas turbines with heat-recovery steam generators and steam turbines, as blocks or components.
From idle plant to power on site.
One unit’s path through redeployment, stage by stage: typically 12–24 months, against about five years for a new heavy-duty unit.
Locate and screen
2–4 weeksWe find the unit through owners, lenders and asset sales, then screen its model, hours, starts and preservation records before anyone travels.
Inspect on site
1–3 weeksWalkdown, borescope inspection and generator tests by qualified specialists establish the unit’s real condition.
Agree the transaction
1–2 monthsScope of supply, title, removal rights, price and conditions are settled before any dismantling starts.
Preserve and dismantle
1–2 monthsThe package is preserved, match-marked and broken into shippable modules, with every item logged.
Heavy-lift transport
1½–3 monthsRoute surveys, port handling and heavy-lift shipping move each module to the overhaul shop or the new site.
Overhaul
3–6 monthsHot-gas-path or major inspection, parts replacement and controls updates set the unit’s performance and remaining life for its new duty.
Install and commission
4–8 monthsFoundations, electrical and fuel tie-ins, first fire and performance testing, with site works running alongside the overhaul.

Complete generation assets
Whole plants assessed for continued operation, redevelopment or relocation.
What we check on an older unit.
An older turbine is only as good as its records and its condition. Every assessment covers the same ground, so options can be compared on equal terms.
- Identity
- Manufacturer, model, serial number and configuration, simple or combined cycle.
- Operating history
- Fired hours, starts, trips and the duty the unit has run.
- Maintenance
- Hot-gas-path and major inspections, parts replaced and open findings.
- Preservation
- How the unit was laid up, humidity control and preservation records.
- Condition
- Borescope results, casings, rotor, combustion system and generator tests.
- Scope of sale
- Generator, controls, auxiliaries, transformers and spares included.
- Site fit
- 50 or 60 Hz, ambient conditions, fuel and emissions limits at the destination.
- Logistics
- Dismantling access, heavy-lift weights and the route to site.
Check your unit’s readiness.
Six questions for owners, operators and lenders. See how ready the unit is for assessment and which documents to prepare.
Understand the asset before defining the solution.
Our assessment considers equipment identity and configuration, operating and maintenance history, preservation records, inspection findings and the items included in the transaction.
Frequency suitability, emissions requirements, refurbishment, dismantling, transport and integration are assessed for the intended destination.
Equipment information is shared with its source and verification status.
| Information | Source | Verification status |
|---|---|---|
| Equipment identity and configuration | Nameplates and OEM documentation | Confirmed on site |
| Operating and maintenance history | Control-system and maintenance records | Records review |
| Preservation records | Owner or operator layup logs | Records review and walkdown |
| Inspection findings | Borescope and condition surveys | Independent inspection |
| Items included in the transaction | Seller’s scope of supply | Inventory walkdown |
Compare the complete route to operation.
Purchase price is one part of the decision.
We compare existing-equipment options with new-build alternatives using the full scope: condition, refurbishment, logistics, installation, warranty, operating performance and commissioning.
Questions about older turbines.
Have a unit in mind or a requirement to fill? Offer a turbine or send a requirement.
Can an older gas turbine supply a data centre?
It can, when the unit’s condition and the supply design match the load. Continuous duty, redundancy and planned maintenance are built into the configuration, often with more than one unit and with storage or grid support.
What if the turbine is 50 Hz and the site needs 60 Hz?
Frequency is set by the generator and, on some units, the gearbox. Changing it usually means a different generator or gearbox, or a frequency converter, so frequency fit is checked at the start.
Which turbines do you look for?
Heavy-duty frame units, aeroderivative and industrial turbines, and combined-cycle equipment, matched to the output, duty and site of each project.
What should an owner send first?
The turbine model and serial number, what is included in the sale, running hours and starts, the date of the last major inspection, preservation records, photographs and the site location.
Do you consider whole plants?
Yes. We assess complete plants for continued operation, redevelopment or relocation, as well as individual units and packages.
How long does redeployment take?
It depends on condition, refurbishment scope, transport and site readiness. We set out a schedule once the unit has been inspected.
Move forward with a defined scope.
For a relevant opportunity, the next stage establishes technical fit, required diligence, transaction scope and the deployment work to be priced and agreed.
