AI data centers are turning to on-site reciprocating-engine power — fast. We make those engines grid-compliant, revenue-ready and fully observable at the register level (Modbus · IEC 60870-5-104 · IEC 61850) — vendor-neutral, across major engine OEMs. We don't sell engines. We're the software brain on top.
Ask the engine copilot → Why OEMs recommend usGrounded on real field-technician knowledge — knock, lambda, oil, cooling, turbo, starting, controllers, Modbus/SCADA, paralleling, gas quality, maintenance & AI-data-center power. Honest: no hallucinated fault codes, no plant data. For a plant-specific diagnosis we connect your asset at register level.
Engine makers win the project on the iron. Offshore and at speed, the bottleneck is integration — and that is exactly our layer.
Direct to the utility / control room over IEC 60870-5-104 & IEC 61850 — and to any controller (DSE, ComAp, Woodward) over Modbus.
Load-following and transient response that dampens AI power swings — multi-unit, multi-market, physically dispatchable.
Fleet health across mixed OEMs — every cylinder, every unit, on its real register. A vendor-neutral digital twin.
Grid-forming proof and local interconnection — the paperwork that gets a site accepted and energized.
We never replace your engines and we never compete on cells or iron. We make your overseas and at-scale delivery faster and de-risked — so recommending Stromfee sells more of your hardware.
Over a mixed fleet — Caterpillar, INNIO Jenbacher, Cummins, Rolls-Royce mtu, Wärtsilä — a single dispatch & monitoring pane, not five OEM dashboards.
Local grid-code & interconnection handled → projects finish and get paid sooner.
The external EMS layer the OEMs themselves point to — complementary to myPlant & co., open to any asset.
Public deployments / announcements as of mid-2026. Honest framing: most are announced or in backlog, not yet operating; figures are operator/OEM statements, not double-counted.
| Region | Key projects (recip) | Lead engine maker | Status |
|---|---|---|---|
| Texas | Oracle / VoltaGrid 2.3 GW; Wärtsilä 790 MW; Hunt; Vantage | INNIO Jenbacher · Wärtsilä | announced/backlog |
| Ohio | ~1.2 GW (Wärtsilä 282+507+412 MW); Meta New Albany | Wärtsilä | announced/under constr. |
| West Virginia | Nscale "Monarch" 2 GW | Caterpillar G3500 | announced |
| Utah | Joule 1 GW firm / 4 GW campus | Caterpillar G3520K | announced/backlog |
| Tennessee | xAI Colossus (mixed) | recip + turbine | operating (partial) |
Source basis: operator & OEM announcements and trade press (2025–2026). Recip-only; turbine-based sites excluded. Where deals overlap (e.g. Oracle / VoltaGrid / INNIO), they are counted once.
We sit above the iron — neutral across the engine makers and integrators driving AI-data-center power.
Reciprocating power for AI data centers needs a neutral dispatch, connectivity and monitoring layer. That's us — across major OEMs, at the register level. Let's scope it.
