Generator sizing from real load data
Size generators based on the actual loads in your model — not a spreadsheet estimate. See the impact of motor starting, load stepping, and steady-state loading on generator capacity.
What you get
Generator kW/kVA sized from the actual loads connected in your model, not manual estimates.
Motor inrush current impact on generator voltage and frequency considered in the sizing.
Continuous loading on the generator calculated from your model's demand.
Generator fault current contribution included in the short circuit analysis.
Bus voltages throughout the emergency system calculated via load flow.
Generator is part of the complete electrical model — not a standalone calculation.
Generator sizing in system context
Standalone generator sizing calculators miss the system. ekx sizes your generator as part of the complete electrical model, so you see real voltage, fault current, and loading impacts.
- kW/kVA requirement calculated from connected emergency loads
- Motor starting impact on voltage visible in the model
- Generator fault contribution included in short circuit analysis
- Bus voltages throughout the emergency system verified via load flow

Motor inrush currents are modeled. You can see the voltage impact at the generator bus and throughout the system when large motors start.
Yes. Generator sizing considers both kW and kVA requirements based on the power factor of connected loads.
Yes. You can model utility sources and generators in the same one-line diagram, with loads connected to each as appropriate.
ekx calculates the required capacity. You select the generator rating from standard sizes available from manufacturers.
