Ask a facility manager what an hour of generator runtime costs and you will get a fuel number. The problem is that fuel is barely half the bill.
The four lines your logbook skips
Maintenance, depreciation, the overhaul cliff and downtime — priced together, they push the true cost of diesel power far above the grid, and far above a properly sized hybrid system.
None of this requires believing anything about the climate. It requires believing your own meter data.
Sizing from telemetry, not thumb rules
Motor inrush collapses inverter-led grids; grid-forming inverters with 2C-rated strings absorb it. The design input is measured load, not a catalogue.
A system guaranteed in the contract is worth more than one promised in the brochure.
What it means for your next decision
Read against NERC, the practical takeaway is simple: the operators who win here are the ones who measure a 2.4MW/4.8MWh plant before they commit capital, not after. Greyfusion publishes the assumptions behind these numbers because confident analysis survives scrutiny.
