When a project needs power, the most useful date is the date usable electricity reaches the load. A factory delivery slot is one part of that schedule. Gas supply, site preparation, electrical equipment, air approvals, protection, testing and commercial arrangements can be equally important.
For buyers facing extended new-generation lead times, EnergyEquipment.com is developing a second route: source existing suitable equipment and define an OEM rehabilitation and support scope around it. The purpose is to bring a credible operating plant forward while preserving a clear path to warranty, performance testing and long-term service.
What the OEM is saying about new orders
In its 21 July 2026 investor Q&A, Wärtsilä said delivery times for new Energy orders had increased over the preceding 18 months and were mainly extending to 2029 and beyond. That is a dated statement about its Energy business, not a universal lead time for every engine, supplier or reserved production slot. Obtain a current project-specific offer before using a delivery date in a financial model. Read the OEM’s report.
The commercial implication is straightforward: waiting for an entirely new engine may not be the only schedule to evaluate. Existing surplus equipment, legacy cores suitable for rehabilitation and manufactured-to-order modular systems each offer a different combination of condition, scope, support and timing.
Compare three complete execution paths
| Path | Potential attraction | Main diligence question |
|---|---|---|
| New OEM equipment | New equipment specification and an established factory supply scope. | Which production slot is contractually allocated, and what is excluded from the delivery date? |
| Existing cores with OEM rehabilitation | Reuse major manufactured components and run project activities in parallel. | Which components are reusable, what must be replaced, and what warranty and performance scope will the OEM contract? |
| Modular new production | Build capacity in repeatable blocks matched to project phases. | Are allocation, acceptance performance, warranty issuer, delivery and local support confirmed? |
A faster route with defined support
The Wärtsilä legacy 34SG pathway begins with inspection and project definition. Following a satisfactory assessment and agreement on scope, the OEM can support rehabilitation with warranty for replaced parts and performed work, project-specific performance guarantees and an LTSA.
Retained blocks and crankshafts do not become new components with a new-component warranty. This is an engineered rehabilitation project, not a factory-new engine at a used-equipment price. The final contracts must resolve coverage, performance conditions and responsibility for equipment outside the OEM’s scope.
The schedule opportunity comes from cores that already exist and work that can proceed concurrently. It should be validated against the actual critical path: alternators, controls, emissions systems, utility interfaces, construction access and acceptance testing. EnergyEquipment.com’s previous 12–18 month planning range is a discussion assumption for selected rehabilitation concepts, not a date promised by the September OEM letters.
Put a value on earlier usable power
A useful comparison asks what an earlier operating date contributes after fuel, variable maintenance, staffing and other incremental costs. For an illustrative project, an extra $250,000 of monthly contribution over six months equals $1.5 million before financing, taxes and execution risk. This is an arithmetic example, not projected income from the offered equipment.
Compare that benefit with the entire incremental project cost. Include acquisition, inspection, dismantling, freight, refurbishment, new electrical equipment, installation, contingency and the cost of maintaining an alternative supply. A cheaper engine that delays permitting or requires extensive unsupported work can be the more expensive project.
Ask for a milestone schedule
Separate contract execution, inspection, engineering freeze, long-lead orders, factory acceptance, equipment release, transport, site completion, commissioning and commercial operation. Identify the owner of each activity and the assumptions that allow it to start. Ask what happens if inspection changes the scope or an allocated slot is missed.
For the Cummins-powered 2 MW pod concept, the supplier’s initial 90-day delivery target is a different proposition from a Wärtsilä rehabilitation schedule. It starts from contract and initial payment and remains subject to reconfirmed production, final scope and logistics. Neither proposal should be treated as unrestricted stock ready to energize.
Start with a requirement that suppliers can answer
Send required net MW, load profile, voltage, frequency, redundancy, fuel composition and pressure, location, emissions constraints and the target date. Distinguish the preferred date from the latest acceptable date. With those inputs, equipment alternatives can be evaluated against the same project boundary.
