Overview#
The Hipower HGM-150 is a 150 kW stationary natural gas standby generator and the largest model in Hipower's HGM series. Above 150 kW, the HNG series picks up larger stationary natural gas requirements. The HGM-150 is built in Olathe, Kansas, and holds CARB certification for California natural gas standby applications.
At 150 kW, the HGM-150 covers mid-large commercial standby: full essential systems in a medical office building, a large restaurant or hospitality operation, or a multi-tenant commercial building with critical refrigeration and communications loads. The broad voltage range — 120/240V through 277/480V — accommodates most California commercial electrical services.
Natural gas supply from the building's utility meter eliminates diesel storage, SPCC compliance, and fuel delivery. For California projects, CARB certification removes the air district variance requirement, enabling standard permit-by-rule approval.
Engine Platform#
The HGM-150 is powered by a PSI 8.8LT CAC — a turbocharged and charge-air-cooled 537 CID (8.8L) V8 industrial gaseous engine from Power Solutions International. This is a larger displacement platform than the GM Vortec 5.7L used in the HGM-55 through HGM-120, producing 206 hp on natural gas and 185 hp on LPG at 1,800 RPM. Marathon Electric provides the alternator (model 431PSL6202) with SE350 AVR. Service follows standard spark-ignited gas generator practice: no DPF, no DEF, spark plugs and oil changes at 1000-hour intervals.
CARB-Certified for California#
Hipower's HGM series holds CARB certification for California natural gas stationary standby. The HGM-150 qualifies for California permit-by-rule — standard air district approval without source test.
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 services Hipower gas generators throughout the Bay Area and Northern California. The HGM-150 is the top of the HGM series — appropriate for mid-large commercial buildings where natural gas is the primary building fuel and diesel standby would add unnecessary compliance complexity.
