The Hipower HNI-200 is a 200 kW standby natural gas generator powered by a PSI 8.8L V8 (537 CID) turbocharged aftercooled high-output engine. The "HO" designation reflects a higher output calibration of the 8.8L platform, optimized to deliver 200 kW at 1800 RPM while remaining within CARB-certified emissions limits.
At 200 kW, this unit serves a broad range of applications: mid-size commercial buildings, edge data centers, medical office buildings with life-safety requirements, and industrial facilities with existing gas infrastructure. Natural gas supply from the utility eliminates diesel storage compliance and fuel management overhead.
PSI's 8.8L V8 TCAC HO is engineered for stationary standby duty at 1800 RPM. The aftercooled turbocharger configuration provides dense intake charge, maximizing output from the 8.8L displacement while controlling combustion temperatures. PSI has an established service network and parts supply chain throughout North America.
Maintenance is simpler than diesel Tier 4 alternatives: no DPF, no SCR, no DEF. Key service items are spark plugs (1000 hours), oil and filter (1000 hours or 12 months), and annual gas line inspection.
Part of the CARB-certified HNI series (30–1000 kW). California permit-by-rule applies — standard air district approval without source test or variance. The 200 kW class has limited CARB-certified natural gas options outside the Big 4, making the HNI-200 a competitive choice for California projects.
OnPoint Generators services natural gas generators in the 200 kW range throughout the Bay Area and Northern California. Facilities with existing gas service — office buildings, medical buildings, and smaller data centers — find that gas standby eliminates the fuel logistics and compliance burden of diesel while delivering equivalent standby protection.

Estimate runtime on this tank
Fuel demand at 75% load
2,100,000 BTU/hr≈ 2100.0 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 engine does the HNI-200 use?
The HNI-200 uses a PSI 8.8L V8 (537 CID) turbocharged aftercooled high-output engine. The HO designation indicates a higher fuel delivery calibration relative to the base 8.8L used in the 150 kW class.
Is the HNI-200 CARB certified?
Yes. The full HNI series (30–1000 kW) holds CARB certification. The HNI-200 qualifies for California permit-by-rule without an air district variance.
Is the HNI-200 suitable for data center standby?
Yes. At 200 kW, the HNI-200 covers partial-floor UPS standby loads and is well-matched for small-to-mid data centers or edge computing facilities with existing natural gas service. No on-site diesel storage is required.
What fuel options are available?
Natural gas, LP, and dual-fuel configurations are available.
How does natural gas standby compare to diesel for data center applications?
Natural gas eliminates fuel storage tank management and diesel delivery logistics. For data centers in California with gas service, the HNI-200's CARB certification removes regulatory friction. The trade-off: gas supply continuity during a seismic or infrastructure event requires evaluation against site risk profile.
Who services HNI-200 units in Northern California?
OnPoint Generators provides maintenance, load-bank testing, and emergency service for Hipower HNI units throughout Northern California.
