100 kVA generator sets
A 100 kVA generator set is a high-power diesel generator set designed for industrial, construction, agricultural, and event applications, as well as critical backup power: it provides continuous, stable power to run machinery and entire facilities.
In this power range, Genergy's GDS diesel series ranges from 47 to 127 kVA, three-phase at 400/230 V, with a 1,500 RPM engine, a copper alternator, a Deep Sea controller, and automatic transfer switch (ATS) capability. Here are the options around 100 kVA.

What is a 100 kVA generator set?
A 100 kVA generator is a high-power generator set consisting of a diesel engine and an alternator, capable of delivering approximately 80–100 kW of useful power. kVA indicates apparent power; the actual power in kW is slightly lower, depending on the power factor. This equipment is designed for intensive professional use: to continuously and reliably power industrial machinery, large facilities, HVAC systems, or technical infrastructure.
It is used both as the primary power source in areas not served by the grid and as a backup system that starts up automatically in the event of a power outage. In sectors where a power outage causes production losses or safety risks (manufacturing, hospitals, logistics centers, data centers), a generator of this capacity is considered critical infrastructure. At Genergy, this capacity is provided by the GDS three-phase diesel generator series.

Frequently Asked Questions About 100 kVA Generators
What can a 100 kVA generator power?
Industrial machinery, HVAC systems, lighting, compressors, pumps, cold storage rooms, offices, or logistics centers—all at once. It’s a power solution designed for industry, construction sites, agriculture, large events, and backup power for critical facilities.
How many kW are in 100 kVA?
kVA represents apparent power, and kW represents useful active power; the ratio between them is the power factor. With the typical power factor (0.8), 100 kVA is equivalent to about 80 kW of useful power. Therefore, when sizing a system, what matters is the actual power consumption (kW) of the installation.
What is the exact power I need?
It depends on the connected equipment, their startup peaks, and hours of use. Add up the power consumption and include a 20–30% margin. In this range, you’ll find models from 47 to 127 kVA; if you tell us about your specific situation, we’ll help you choose the right model.
Why diesel at 1,500 RPM?
Diesel generators running at 1,500 RPM operate at a lower speed: less vibration, lower fuel consumption, less wear and tear, and a longer service life. It is the professional choice for continuous and intensive operation.
Is a 100 kV generator three-phase?
Yes. The models in this series are three-phase (400/230 V), which is standard for powering industrial machinery and high-power equipment; they also offer a single-phase 230 V power supply.
Do the 100 kV generators have an automatic start-up feature?
They are equipped for automatic startup in the event of a power outage via an ATS transfer switch (depending on power rating), so they start up automatically during an outage and restore power within seconds.
Do you offer a warranty and technical support?
Yes. Genergy is a manufacturer that offers a 3-year comprehensive warranty (covering labor, transportation, and replacement parts), its own after-sales service, and a network of distributors throughout Spain.
The recommended power ratings are approximate and depend on each installation. The ATS panel may not be included, depending on the model.
