Diesel Generators
Diesel generators provide backup or continuous electrical power through a diesel engine driving an AC alternator, sized in kVA and rated to ISO 8528 as prime or standby duty. NLS sources diesel generator sets from 20kVA to 2500kVA for contractors, hospitals, and industrial sites across Saudi Arabia, priced in USD with ambient-derated output for local conditions.
A diesel generator set pairs a diesel engine with an AC alternator on a common baseframe, control panel, and fuel system, sized to carry a defined electrical load when utility power fails or where no grid connection exists. ISO 8528 sets the reference for how a set is rated: prime power covers a variable load with no fixed time limit for continuous running, while standby power covers a set that only carries load during a utility outage, at a higher output but with an annual running-hour cap. A generator's plate kVA at 40°C ambient at sea level moves once installed in Saudi Arabia, where summer ambient can sit past 45°C and dust loading runs higher than the test standard assumes; both the engine and alternator need derating, so NLS works from actual site elevation and design ambient rather than the catalog rating.
NLS sources diesel generator sets from about 20kVA up to 2500kVA, single unit or multiple units in parallel, open skid or acoustic canopy, with control panels built for auto-start, remote monitoring, or manual local operation. Engines and alternators are matched to the duty class a project specifies, referencing ISO 8528-1 for performance class and IEC 60034 for alternator output, with fuel tank, exhaust silencing, and battery-start systems built into the package rather than quoted as separate line items.
Saudi projects call for diesel gensets as legally mandated backup for hospitals and life-safety systems under NFPA 110 (Type 10, Level 1 for hospital emergency power), as primary power on remote construction and industrial sites with no grid connection, and as N+1 redundant backup for data centers and process plants where an outage carries a real cost. NLS already supplies aviation and hospital infrastructure across Saudi Arabia, so a genset package for a hospital emergency system is scoped against the same NFPA 110 transfer-time and run-time requirements the rest of the electrical package has to meet.
Sourcing works the same way as NLS's other categories: send site elevation, design ambient temperature, connected load or load schedule, and duty class (prime or standby), and NLS returns a priced quote in USD with a lead time based on engine and alternator availability. Common sizes in the 100-500kVA range typically source faster than large custom-built sets, which may need a factory lead time confirmation before delivery can be locked in.

Frequently Asked Questions
How much does a diesel generator cost in Saudi Arabia?+
Price runs on kVA size, enclosure type and engine brand tier, and above roughly 500kVA the engine brand moves the number more than sheer size does. Fuel tank arrangement, acoustic treatment and control panel specification all shift it further. Send NLS a load schedule and design ambient temperature for an accurate quote in USD.
Who supplies backup generators for hospitals in Riyadh?+
NLS sources and supplies diesel generator sets sized and configured to NFPA 110 requirements for hospital emergency power, for projects in Riyadh and across Saudi Arabia, alongside the aviation and hospital infrastructure NLS already supplies in the Kingdom.
What lead time should I expect for a diesel generator in Saudi Arabia?+
Lead time depends on set size and configuration: common sizes in stock configurations can ship in a few weeks, while large custom-built sets with acoustic enclosures or paralleling controls typically need 8-16 weeks from the factory. NLS confirms an exact lead time once load, duty class, and enclosure type are set.
