Equipment classes.

High simple-cycle efficiency, ten-minute start to full load, and load-following capability. The default choice where the interconnection has slipped and the campus needs firm capacity ahead of backfeed. Variant matters — a PC and a PF are different machines to a permitting team.

Fast-start, high availability, modular, and among the most genuinely redeployable machines in the installed base. Deep industrial and marine fleet, and the aftermarket to support it.

Industrial RB211 and Trent 60 packages. Core aeroderivative inventory alongside the LM fleet, with a live parts and repair market.

GE TM2500 and comparable trailer-mounted units. Minimal civil works, weeks rather than quarters to first fire, and relocatable when the utility service date finally arrives. The workhorse of real bridge power.

The dominant fleet in the 5–22 MW behind-the-meter industrial band, and the right granularity for a phased campus buildout. Large secondary market, well-supported aftermarket.

Wärtsilä 34SG-class gas engines, Caterpillar 3516 / C175 and mtu Series 4000 diesel gensets, and comparable platforms. Modular, excellent part-load heat rate, strong block-load acceptance, and N+1 granularity without stranding capacity.

Among the most-traded used gas turbines in the world. Simple, forgiving, widely understood, and economic to relocate into industrial captive service.

Load-geared, and offered in both 50 and 60 Hz — the load gear and generator set the frequency, so changing it means new ones. One of the most tradeable frame machines in the market, with a live aftermarket and a long record in cogeneration and industrial captive power.

The E-class machine that actually moves. Deep parts and third-party repair support, well-understood rotor life limits, and a long redeployment record.

Relocates far less freely than the E-class: units are often married to a matched HRSG and steam turbine, the DLN 2.6 combustion system is tightly held, and the generational splits are not parts-interchangeable. We transact in them, but we are candid about which ones are economic to move.

The D5 and D5A have a long and genuine second-life record. The F-class is a different commercial proposition and relocates far less often. Treat them as separate machines, because they are.

Large machines with an installed base concentrated in Europe, the Middle East, and Asia. The V84 is the 60 Hz sibling — a different machine, not a conversion.

Large frame with sequential reheat combustion. New-unit technology and OEM parts IP passed to Ansaldo Energia in the GE/Alstom divestiture; GE retained service on most of the legacy installed base. The GT24 is the 60 Hz version.

Frequently the hardest long-lead item on a campus — harder than the turbine. A tested GSU of the right rating and impedance, with matching switchgear and protection, can be the difference between energizing on schedule and waiting on a transformer queue.

Steam turbines out of retiring combined-cycle stations, plus generators, exciters and load gears, fuel gas compression, SCR and CO catalyst, transformers, switchgear, and control systems — including migration off obsolete platforms (Mark V, Teleperm, WDPF). Controls are frequently the real constraint on a redeployment schedule.
