Portable Generators

A portable generator is a self-contained power source, an engine, an alternator, a fuel tank and a control panel on one skid or trailer frame, built to supply electrical load wherever grid power isn't available or isn't reliable enough to depend on. It exists to solve two different problems that look similar: providing prime power on a site with no grid connection yet, and providing standby or backup power on a site where the grid exists but can't be trusted to stay up.

NLS sources diesel and petrol units across a capacity range built around actual load, not just headline kVA. Small petrol and diesel units, roughly 2 to 10 kVA, cover site offices, small tool loads and lighting on a compound not yet connected to permanent power. Mid-range diesel units, 10 to 50 kVA, run construction site power, pumps, welding sets and temporary site lighting. Larger diesel generating sets, 50 to 100 kVA and above, back up critical loads or supply a site's full temporary power demand where grid connection is delayed. NLS sources generating sets built to ISO 8528, the standard covering reciprocating internal combustion engine driven generating sets, including performance, ratings and how a unit's output is defined and tested.

On Saudi projects, portable generators supply power during the gap between site mobilization and permanent grid connection, back up critical loads like medical or life-safety equipment on hospital builds, and support remote or temporary works, aviation infrastructure sites, pump stations, and lighting towers, where extending permanent power isn't practical for the project duration. Sizing has to account for starting load, not just running load, since motor-driven equipment (pumps, compressors, welding sets) can draw several times its running current at start-up, and an undersized generator trips or stalls under that surge even if its steady-state rating looks adequate.

NLS quotes portable generators against a site's running and starting load profile, fuel preference, and duty class (standby versus prime power), and returns a priced quote in USD. Standard diesel units in common capacity bands typically source fastest; larger sets, sound-attenuated enclosures, and units built to a specific project spec are more often built to order and carry a manufacturer-confirmed lead time.
