A legacy engine can support a serious power project when the rebuild, acceptance test and long-term service obligations have a clear owner.

A direct OEM path changes the project discussion
A low purchase price is useful only if the equipment can become a dependable operating asset. We are working with Wärtsilä on a rehabilitation path for legacy 34SG engines and plants, with OEM assessment, a defined rebuild scope and the potential to contract for warranty, performance commitments and long-term service.
The useful distinction is accountability. Instead of assembling unsupported promises from several repair vendors, the buyer can take a defined application and asset package into an OEM technical and commercial process. That can make lender, insurer and operating-team diligence more concrete.
What the OEM information supports
The Wärtsilä correspondence and supporting Q&A supplied for this program, dated 23 September 2026, describe a conditional path. Warranty attaches to agreed work and replaced components. Retained legacy components do not automatically receive the same coverage as new parts. Output guarantees and an LTSA must be negotiated around the actual fuel, duty, installation and service scope.
The OEM information package is available to parties with a serious project interest on request. The initial discussion should establish application, target date, electrical requirements and required contractual protections. Asset-specific inspection and engineering follow.
Spain: three engines, one set of assets
The current Spain offer comprises three 18V34SG engines with reported historical nameplates totaling 17.94 MW and approximately 10,000 hours since their last OEM overhaul, per the owner. The proposed 380 kW-per-cylinder planning basis produces 20.52 MW across 54 cylinders; this is a rehabilitation concept, not an existing nameplate rating or a signed performance guarantee.
The three engines can be discussed individually or as one Spain package. These offers overlap; there are three physical engines. The two UK units are no longer available and the previous combined UK + Spain offer has been retired.
50 Hz today; engineer the requested destination
The legacy equipment is 50 Hz. A proposed 60 Hz configuration requires an engineered engine-generator package and the appropriate new generator-end scope. Specify voltage, frequency, fuel quality, site ambient, duty and required net output before choosing the refurbishment route.
Indicative program planning is 6–18 months; new OEM generator ends and key components may take around 12 months. Civil works, utility interfaces and portions of site preparation can proceed in parallel once interfaces are released. Purchasing the engines early does not eliminate the engineering and long-lead equipment on the critical path.
Turn the concept into an executable offer
Request three aligned documents: the asset schedule, the OEM rehabilitation scope and the delivery/acceptance schedule. The commercial offer should identify who carries integration risk, how performance is tested and what happens if a milestone is missed. That is how legacy equipment becomes a credible project alternative.
