As airports and ground handling operations reassess their equipment strategies, one question comes up again and again: Should we stick with diesel GSE, or transition to electric?
The purchase price is only part of the story. To make an informed decision, operators must look at total cost of ownership (TCO)—what the equipment truly costs over its usable life.
In this post, we’ll compare electric and diesel ground support equipment (GSE) through the lens of 5‑year total cost of ownership, breaking down operating costs, maintenance, infrastructure, and long‑term value.
What Is Total Cost of
Ownership (TCO)?
Total cost of ownership includes all expenses associated with owning and operating equipment over time—not just the initial purchase.
For GSE, TCO typically includes:
- Acquisition cost
- Energy or fuel costs
- Maintenance and repairs
- Downtime and reliability impacts
- Infrastructure requirements
- Residual or replacement value
Looking at TCO helps airport operators move beyond upfront price tags and understand long‑term operational impact.
Upfront Acquisition Costs
Diesel GSE
Diesel-powered GSE usually has a lower upfront purchase price. These machines are well-established, widely available, and familiar to maintenance teams.
Pros:
- Lower initial capital expense
- No charging infrastructure required
- Familiar technology
Cons:
- Higher operating costs over time
Electric GSE
Electric GSE often requires a higher initial investment, particularly when charging infrastructure is included.
Pros:
- Incentives or rebates may offset cost
- Lower long-term operating expenses
Cons:
- Higher upfront cost
- Initial planning for charging access
While electric equipment may cost more at the time of purchase, TCO analysis shows that upfront cost rarely tells the full story.
Energy Costs Over 5 Years
Diesel Fuel Costs
Diesel GSE is subject to:
- Fuel price volatility
- Idling inefficiencies
- Higher per-hour operating costs
Over five years, fuel expenses can quickly surpass the initial savings of lower purchase prices.
Electricity Costs
Electric GSE benefits from:
- Stable and predictable energy pricing
- Higher energy efficiency
- Reduced energy waste during idle periods
Even when accounting for charging infrastructure, electric GSE typically costs significantly less to operate per hour than diesel equipment.
Maintenance and Repair Costs
Diesel Maintenance
Diesel equipment includes:
- Engines
- Transmissions
- Fuel systems
- Exhaust and emissions components
These systems require regular servicing, oil changes, filter replacements, and eventual major repairs.
Electric Maintenance
Electric GSE typically has:
- Fewer moving parts
- No oil changes or exhaust systems
- Reduced brake wear due to regenerative braking (on many models)
As a result, electric equipment often sees lower maintenance costs and reduced downtime over a five-year period.
Downtime, Reliability,
and Operations
Reliability has a direct impact on cost—whether through delayed operations or spare equipment needs.
- Diesel GSE may experience downtime related to mechanical wear
- Electric GSE offers more consistent performance with fewer failure points
Additionally, electric GSE can be operated indoors without emissions concerns, improving flexibility for hangars and maintenance areas.
Infrastructure and Facility Considerations
Diesel Infrastructure
Diesel fleets require:
- Fuel storage
- Spill prevention measures
- Environmental compliance processes
These costs are often overlooked but add operational complexity.
Electric Infrastructure
Electric fleets require:
- Charging stations
- Electrical capacity planning
While infrastructure investment is higher upfront, it tends to scale more efficiently over time, especially as fleets grow or transition fully to electric.
5-Year TCO Comparison
(High-Level)
Cost Category | Diesel GSE | Electric GSE |
Purchase Price | Lower | Higher |
Fuel / Energy | Higher | Lower |
Maintenance | Higher | Lower |
Downtime Risk | Moderate | Lower |
Infrastructure | Lower | Moderate |
Total 5-Year Cost | Higher | Lower |
While results vary by operation and usage intensity, electric GSE frequently delivers a lower total cost of ownership over five years, particularly in high‑utilization environments.
Sustainability and Regulatory Impact
Beyond cost, electric GSE supports:
- Emissions reduction goals
- Noise reduction on the ramp
- Compliance with evolving airport and regional regulations
Many airports are already incentivizing or requiring low‑emission ground equipment, making electric GSE a forward‑looking investment.
Final Thoughts
Diesel GSE may still make sense for certain applications, especially in lower‑usage or remote environments. However, when evaluating total cost of ownership over five years, electric GSE often emerges as the more cost‑effective, efficient, and future‑ready option.
The key is evaluating your operation’s duty cycles, utilization rates, and long‑term strategy—not just the sticker price.
