The Hipower HGM-65 is a 60 kW stationary natural gas standby generator in Hipower's HGM series — a compact natural gas lineup manufactured in Olathe, Kansas. At 60 kW, the HGM-65 provides reliable standby coverage for small-to-mid commercial facilities with existing gas service, eliminating the need for on-site diesel storage and the compliance obligations that accompany it.
CARB certification positions the HGM series for California standby projects where air district compliance is required without a source test. For California facility owners, natural gas standby under CARB certification represents the simplest path to code-compliant emergency power.
The HGM-65 engine OEM and model designation has not been confirmed from available OEM documentation and is marked for verification. The unit operates at 1800 RPM on natural gas or LP. Maintenance follows standard spark-ignited gas generator practice: spark plugs and oil changes at 1000-hour intervals, annual gas system inspection.
Hipower's HGM series holds CARB certification for stationary natural gas engine applications. California permit-by-rule applies to the HGM-65, enabling standard air district approval without a source test or variance process.
OnPoint Generators maintains natural gas standby generators throughout Northern California. The HGM-65 is a compact, straightforward unit for small commercial applications where natural gas is already the primary energy source.

Estimate runtime on this tank
Fuel demand at 75% load
630,000 BTU/hr≈ 630.0 cf/min @ 1,000 BTU/cf
On utility natural gas the runtime is generally unlimited provided the supply line and meter can deliver this BTU/hr at the engine's required inlet pressure (typically 5–14" WC residential, up to 5 psi commercial). Confirm against the OEM's published fuel-pressure spec.

Frequently Asked Questions
What is the HGM series?
The HGM is Hipower's stationary natural gas generator series for compact, fixed-installation commercial standby. The HGM-65 sits at 60 kW in the middle of the HGM lineup. Engine OEM and model are unconfirmed. <!-- NEEDS VERIFICATION: HGM-65 engine OEM and model -->
Is the HGM-65 CARB certified?
Yes. Hipower's HGM natural gas series holds CARB certification for California stationary standby applications.
What are the fuel options?
Natural gas and LP. The HGM-65 draws fuel from the building's utility gas service.
What is the difference between the HGM-55 and HGM-65?
The HGM-65 provides 60 kW vs 53 kW on the HGM-55 — a 13% increase suitable for slightly larger standby loads. Both use natural gas and hold CARB certification.
What loads does 60 kW of natural gas standby support?
60 kW covers essential building systems in a small-to-mid commercial building — HVAC, lighting, refrigerated display, POS and networking equipment. Confirm with a load analysis before sizing.
