Overview#
The Hipower HRNG-1250 is a 940 kW trailer-mounted natural gas generator — the flagship of Hipower's HRNG mobile series and one of the largest natural gas trailer generators available. At nearly 1 MW of temporary power, the HRNG-1250 is used for the most demanding temporary standby scenarios: replacing major standby generators while maintaining full facility power, bypassing large electrical switchgear, and providing emergency coverage for critical infrastructure campuses.
Like all HRNG units, the HRNG-1250 connects to the site's permanent natural gas supply — no on-board diesel, no delivery logistics, no SPCC risk. At 940 kW, gas supply infrastructure is a defining project constraint: the site must have very high utility gas capacity, and a mechanical engineer must design the complete gas system (meter, regulator, piping) for the full-load BTU demand. Utility coordination typically requires substantial lead time for service upgrades at this scale.
CARB certification makes the HRNG-1250 suitable for California temporary standby without air district variance. At this power class, CARB-certified mobile natural gas options are essentially unique to Hipower's HRNG series.
PSI Engine Platform#
The HRNG-1250 is powered by a PSI natural gas engine running at 1800 RPM. PSI supplies spark-ignited engines to multiple standby generator manufacturers and maintains a broad parts and service network across North America. The specific PSI model designation for this output class is pending verification from OEM documentation — service follows standard PSI spark-ignited practice: spark plugs and oil at 1000-hour intervals, annual gas system inspection, no DPF, no DEF.
CARB-Certified for California#
Hipower's HRNG series holds CARB certification for California temporary natural gas standby. The HRNG-1250 qualifies for California permit-by-rule at 940 kW.

Our Service Experience#
OnPoint Generators supports large HRNG deployments in Northern California. The HRNG-1250 requires thorough pre-deployment gas system engineering, comprehensive commissioning, and a documented maintenance plan throughout the rental period. For facilities planning major bypass projects at this scale, OnPoint provides full deployment planning and on-site support.
