Overview#
The Hipower HGM-100 is a 96 kW stationary natural gas standby generator in Hipower's HGM series. Near the 100 kW threshold that defines the boundary between light-commercial and mid-commercial standby, the HGM-100 serves medical offices, multi-tenant commercial buildings, and mid-size hospitality operations where natural gas service is established.
CARB certification enables California permit-by-rule for this unit — straightforward air district approval without source test or variance. For California building owners and property managers, the combination of utility-supplied gas fuel and CARB certification removes two of the most common standby compliance complications: fuel storage permitting and air district approval.
Engine Platform#
The HGM-100 is powered by a General Motors Vortec 5.7LTCAC — a turbocharged and charge-air-cooled variant of the 350 CID (5.7L) V8 small-block platform, producing 145 hp on natural gas and 155 hp on LPG. The charge air cooler increases power density over the base turbocharged 5.7LT model used in the HGM-80. Marathon Electric provides the alternator (model 362CSL1606) with SE350 AVR. The unit operates at 1800 RPM on natural gas (96 kW standby) or LPG (80 kW standby). Maintenance follows spark-ignited gas generator standards: spark plugs and oil changes at 1000-hour intervals, annual gas system inspection. No DPF, no DEF.
CARB-Certified for California#
Hipower's HGM series holds CARB certification for California natural gas stationary standby. California permit-by-rule applies to the HGM-100, enabling standard air district approval.
Service and Maintenance#
- Oil and filter: 1000 hours or 12 months
- Spark plugs: 1000 hours
- Air filter: 500 hours
- Gas line and regulator: Annual inspection
- Major overhaul: 30,000 hours
Our Service Experience#
OnPoint Generators maintains Hipower natural gas generators throughout Northern California. The HGM-100 is appropriate for mid-commercial buildings where gas is the primary fuel and diesel standby would add storage and compliance complexity without operational benefit.
