Generator power guide

1,250 kVA diesel generators.

Compare UK-designed and UK-manufactured 1,250 kVA diesel generator options and nearby ratings from Baudouin, Cummins, Perkins. Check the exact prime and standby output, engine and enclosure before selecting.

Compare exact outputs

Options around 1,250 kVA.

A rounded GPS model class is not a guaranteed duty rating. The tables below identify the actual documented output for each reference configuration.

High-capacity power projects

Specify 1,250 kVA around your load.

High-capacity installations need a complete engineering review of load behaviour, cooling, exhaust, fuel storage, switching and service access. Confirm the installation drawing and rated operating conditions before procurement.

At a power factor of 0.8, 1,250 kVA corresponds to 1000 kW mathematically. That conversion is not a substitute for the manufacturer’s duty rating or a starting-load assessment.

Discuss your load schedule
Does a 1,250 kVA model deliver 1,250 kVA continuously?

The model class alone does not establish continuous capability. Check prime and standby ratings and the manufacturer’s load-profile conditions. Confirm the intended run hours and average load when requesting a quotation.

Can I get a canopied 1,250 kVA generator?

Compare the canopied entries above, then confirm enclosure dimensions, sound requirements and final duty rating with GenPro.

Which engine brands are available at this output?

The comparison above includes Baudouin, Cummins, Perkins. Some are close alternatives rather than an exact match; use the electrical rating table to compare them.
