Overview#

The Triton Power TP-NG100-S-K-UL is a 100 kW natural gas standby generator powered by a PSI (Power Solutions International) 5.7LT CAC turbocharged V-8 engine running at 1800 RPM. This unit is part of Triton's EPA-certified natural gas generator lineup, UL2200 listed for the US and Canadian markets. Paired with a Leroy Somer Class H insulation alternator, the TP-NG100 delivers 100 kW standby and 90 kW prime power for mid-size commercial and industrial applications.

The PSI 5.7L turbocharged engine with charge air cooling provides strong power output from a compact displacement, purpose-built for natural gas combustion. Three-phase output is available at 120/208V and 277/480V with a 60 Hz frequency. At 64 dBA, the unit maintains acceptable noise levels for commercial installations. The 100 kW class is one of the most commonly specified sizes for office buildings, retail centers, and light manufacturing facilities.

Our service experience#

The PSI 5.7LT CAC is a proven gas engine platform with good parts availability through PSI's dealer network. At 100 kW, this unit handles the full electrical load for most mid-size commercial buildings. Turbocharged gas engines require attention to charge air cooler maintenance and boost pressure monitoring, but overall service demands are lower than comparable diesel units due to cleaner combustion.

Estimate runtime on this tank

Fuel demand at 75% load

1,050,000 BTU/hr1050.0 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 does the 'CAC' designation mean on the PSI 5.7LT engine?
CAC stands for Charge Air Cooled (also known as intercooled). The turbocharger compresses incoming air, and the charge air cooler reduces the temperature of that compressed air before it enters the combustion chambers. This improves power density, fuel efficiency, and engine longevity compared to a non-intercooled turbocharged engine.
How much natural gas does the TP-NG100 consume at full load?
Natural gas consumption for a 100 kW generator typically ranges from 1,200-1,400 cubic feet per hour (CFH) at full load, depending on gas BTU content and ambient conditions. Your local gas utility can confirm whether your service line can sustain this flow rate at the required pressure. A dedicated gas meter and regulator may be needed.
Can the TP-NG100 run on propane (LP) as well as natural gas?
The TP-NG100-S-K-UL is configured for natural gas operation. While PSI engines can be factory-configured for LP (propane) fuel, converting between fuel types requires changes to the fuel system, regulator, and engine calibration. Contact Triton Power or an authorized dealer to inquire about LP-configured models.

Why we recommend Triton Power

Triton Power is our value brand for mobile and portable diesel generators, and an emerging option for industrial standby. When MQ Power's pricing is a stretch or lead times are too long, Triton delivers comparable capability at a lower price point with faster availability.

We are developing our Triton Power sales relationship and building fleet experience. Every engine platform Triton uses — Perkins, John Deere, Kubota, Scania, Volvo — is one we already service daily across other brands. Triton's open architecture means our technicians can maintain these units with standard tooling and widely available parts.
