Engineered to meet stringent IATA standards and tailored for integration with global airport ramp operations.
The global aviation ecosystem is facing an unprecedented transformation. As airports and commercial airlines strive for net-zero carbon targets, the electrification of Ground Support Equipment (GSE) has progressed from a secondary sustainability objective to a core regulatory requirement. Among these critical systems, the Towable Ground Power Unit (GPU) acts as the central mechanism for reducing auxiliary engine runtimes, dramatically cutting jet fuel consumption and emissions while aircraft are stationed at the gate.
Traditionally, ground power relied on diesel-driven generator units. These conventional configurations, while reliable in terms of uptime, represent a major point source of carbon dioxide, nitrous oxides, and fine particulate matter on the airfield. In response, modern manufacturers are transitioning towards zero-emission technologies. By utilizing advanced solid-state lithium-ion battery architectures and ultra-efficient frequency converters, custom towable GPUs are redefining operational footprints globally.
"The shift towards towable solid-state and hybrid GPUs is estimated to reduce airport ground-level carbon emissions by up to 85% compared to legacy diesel generators. For hubs managing over 100,000 movements annually, this equates to thousands of metric tons of CO2 eliminated per year."
From a commercial perspective, ground handlers and airlines evaluate GPU acquisitions based on the Total Cost of Ownership (TCO). While the capital expenditure (CAPEX) for custom solid-state and smart-hybrid towable GPUs is higher than basic diesel models, the operating expenditure (OPEX) savings are immense. Electric units bypass the volatile costs of diesel fuel, require significantly fewer preventative maintenance hours (with no oil changes, piston rings, or fuel filters to replace), and boast operational lifespans exceeding 10 to 15 years.
How custom engineering accommodates regional variations in grid stability, load profiles, and output frequencies.
A custom towable GPU must provide clean, stable power directly to the aircraft’s electrical bus system. This typically requires either a 400Hz alternating current (AC) output for narrowbody and widebody passenger aircraft or a 28.5V direct current (DC) output for turboprops, regional jets, and helicopters. The engineering complexity lies in maintaining strict voltage and frequency tolerances, even under sudden step-loads when aircraft systems (such as high-draw environmental control packs) are turned on.

Our custom towable GPU lines employ double-conversion inverter topologies to guarantee complete isolation of the output from incoming line transients during recharging. In battery-only configurations, the internal battery management system (BMS) controls the discharge curves, optimizing active cooling cycles via integrated liquid-cooling plates. This ensures that even under maximum payload in high-ambient operations, the cells remain within safe temperature thresholds, preserving cell cycle lifetime (exceeding 4,000 cycles at 80% Depth of Discharge).
