The lines behind each row
All 37 vendorsHow to read the columns
Methodology- Smallest unit kW
- Lowest published electrical output of one generating unit in the named Lines, in kWe. Portfolio minima may include portable models. Standby where available; kVA-only figures assume 0.8 power factor. Consult Rating basis and scope; blank when unverified.
- Largest unit kW
- Highest published electrical output of one generating unit in the named Lines, in kWe. Standby where available; other duty and frequency bases are disclosed in Rating basis and scope. kVA-only figures assume 0.8 power factor. Mechanical output and multi-unit totals are excluded.
- Prime mover
- What turns the alternator in the named lines: a reciprocating (piston) engine, a gas turbine, or both.
- Fuels
- Fuels the vendor lists for the named lines: diesel, HVO (hydrotreated vegetable oil, EN 15940), natural gas, biogas, propane, hydrogen blends.
- Hydrogen-capable
- At least one named line runs on a hydrogen blend or is sold as hydrogen-ready, per the vendor. Read the Hydrogen field for the share and conditions.
- Lines
- The product series this record covers. Ratings, fuels and emissions refer to these lines, not to the vendor's whole portfolio.
- Capacity and lead-time news
- The latest dated, sourced statement on factory capacity, expansion investment or lead time for these lines, from the vendor, a filing or trade press. Month and year first.
