Transformer fleets kept in service while replacement is years away
Condition assessment, oil treatment, rehabilitation and commissioning, bought as a programme for a transformer fleet. With new units years away, life extension is the work that can start this year. Where the capability is not local, the plant, test sets and spares travel to the site.
Replacement runs about 128 weeks. Rehabilitation runs in weeks.Average lead time for a new power transformer, from US figures.Transformer life extension

A failing transformer usually presents three bad options
Units running past their design life, chronic overloading, cycling from renewable in-feed, heat, dust and coastal salt all accelerate ageing. Then the choices narrow.
- 01
Replace it
US figures put the average lead time for a new power transformer at around 128 weeks, with specialised orders extending to four years. It is one order book, and buyers in every market queue in it on the same terms — then add freight, inland transport and customs.
- 02
Ship it out for workshop repair
Months out of service, and freight costs that on a remote site can approach the value of the asset itself.
- 03
Run it to failure
The real incumbent in many fleets. It is a decision, even when nobody makes it deliberately, and it is usually the most expensive one.
Programmes, not line items
Utilities, industrial operators, IPPs and development-finance programmes buy a defined programme with an outcome. Condition assessment is the natural first step: low commitment, high insight, and it defines everything after it.

A structured survey of your transformer population that produces a ranked, evidence-based picture of asset health and a prioritised intervention plan.

Rehabilitation and life extension
Refurbishing a degraded transformer and returning it to reliable service instead of replacing it — weeks instead of years, at a fraction of replacement cost.
Work executed and reported against
IEC 60214-1IEC 60422IEC 60296 - 03
Oil management programmes
Ongoing custody of transformer oil condition across a site or fleet. A single oil test is data; a trend is a decision.
Work executed and reported against
IEC 60422IEC 60814IEC 62021-1+2 - 04
Installation and commissioning
New assets from delivery to energisation, with the test evidence a lender or an asset owner reviews before accepting the asset.
- 05
Substation and network services
Primary and secondary equipment across the substation, not only the transformer.
- 06
Emergency and failure recovery
Mobilised breakdown response to remote sites, and the forensic work that establishes what actually happened.
Work executed and reported against
IEC 60076-18 - 07
Training and capacity building
Capability that stays behind after demobilisation. Frequently a contractual requirement where a development bank funds the work.
- 08
Maintenance contracts and O&M
Multi-year scheduled maintenance across a site or network, with the records and trending an asset manager can report from.
Standards we work and test to
Published international standards. Citing a method states how the work is done and what it is measured against; it is not a certification claim.

Programme scope builder
Choose what testing or inspection has shown, and see the tests that characterise it, the standards it is read against and the programmes that address it.
Reach is part of the scope
For a remote or cross-border site, the programme also carries shipping, temporary import, customs, permits, abnormal-load transport, site generation, fuel and water planning, satellite communications, and a contingency for the part that does not clear customs. It is planned before the technical work, because it decides whether the technical work happens.
Mobilisation — eight stages, enquiry to demobilisation
Enquiry
Assets, site, symptoms and constraints. Enough to say honestly whether we are the right supplier.
- 02
Site survey
Access, condition and scope confirmed on the ground before a price is fixed.
- 03
Mobilisation plan
Equipment list, shipping route, clearance path, permits, team and dates.
- 04
Shipping and clearance
Consignment moves under temporary import, with clearance tracked to a date.
- 05
Team deployment
Technicians travel once the plant has cleared, not before.
- 06
On-site works
The scope executed against the agreed method statements and safety regime.
- 07
Testing and handover
Post-intervention test evidence, compared against the pre-intervention baseline.
- 08
Demobilisation
Plant re-exported, site left clean, used oil removed under a documented chain of custody.

Sectors
The asset is similar; the consequence of losing it is not.
10 sectorsShow allHide
Transmission and distribution utilities
Ageing fleets and reliability targets, with the work funded through a regulated investment plan or a development-bank rehabilitation programme. Either way, each intervention has to be justified with condition evidence.
Manufacturing and heavy industry
Cement, steel, textiles, food processing and chemicals — continuous processes where an unplanned transformer outage stops the line.
Independent power producers
Contractual availability obligations, and lenders who require documented, auditable asset management. Test evidence is a reporting deliverable, not a nicety.
Oil, gas and petrochemicals
Onshore and offshore, hazardous area discipline, and a consequence of failure measured in more than lost production.
Renewables and storage
Solar plants, wind farms, battery storage and collector substations, frequently remote and frequently commissioned to a fixed grid-connection date.
Mining and metals
Remote sites, heavy and harsh duty, and an extremely high cost of downtime. Often self-generating, which makes the transformer a single point of failure for the whole operation.
EPC contractors
Installation and commissioning packages inside a larger project, where the only thing that matters is mobilising on the date agreed.
Critical infrastructure
Hospitals, airports, water utilities and ports, where the tolerance for an unplanned outage is effectively zero.
Telecoms and data infrastructure
Distributed power assets whose reliability underpins service availability across a whole network.
Rural electrification and mini-grids
Distribution transformer fleets spread across long distances, usually under development-finance programmes with their own procurement rules and reporting.
Start with a condition assessment
Tell us the assets, the site and the situation. If the fleet's condition is unknown, an assessment is the lowest-commitment way to find out what you actually have — and it defines whatever comes next.
Contact
The more you tell us up front, the more useful the first reply will be. If the fleet's condition is unknown, say so — that is the most common starting point and it has its own answer.
