A refuse truck is close to the worst duty cycle you can give a diesel engine, and for the same reasons it is close to the best one you can give an electric drivetrain. NREL's duty-cycle work puts refuse collection at 50.62% idle, 2.68 stops per mile and an average 21.26 mph — against 0.24 stops per mile for a drayage cycle. Half the shift burning fuel while stationary, and eleven times the braking events. CARB's analysis names refuse trucks among the categories where battery electric shows savings "even in the early years," and Argonne scales battery electric powertrain repair cost at 60% against a diesel's 100%. The purchase premium is still real, and a published per-mile total for this exact application does not yet exist — which makes your own routes the evidence. Book a refuse TCO review.
The Duty Cycle That Punishes Diesel Hardest
Why collection routes produce the strongest electric business case of any vocational application, which of the eight cost components the duty cycle actually moves, and which ones no model can tell you yet.
What a Collection Route Actually Looks Like
Two measurements from NREL's duty-cycle analysis carry most of the economic argument, and they point the same way.
A drayage truck stops roughly once every four miles. A refuse truck stops 2.68 times every mile, and spends more than half its working day not moving at all. For a diesel engine both of those facts are pure loss: fuel consumed at idle produces no work, and every stop converts momentum into brake heat. For an electric drivetrain the first costs almost nothing and the second returns energy to the battery.
Why the Same Numbers Cut Both Ways
The mechanism matters more than any single cost figure, because it is what makes the refuse case different from a long-haul case.
A diesel engine at idle converts fuel into heat and noise and moves the truck nowhere. An electric drivetrain at a standstill draws essentially nothing beyond accessories.
Each stop is kinetic energy. A diesel sheds it through the brakes as heat. Regenerative braking returns a meaningful share of it to the battery, and does so 2.68 times per mile.
Low speed means low power demand, and NREL's analysis is explicit that electrified powertrains “operate with higher efficiencies at lower percentages of total power output” — which it describes as “the opposite of conventional diesel engines.”
That last point is the one worth carrying into a budget meeting. It is not a vendor claim but NREL's own framing in its Class 8 analysis: electrified powertrains are most efficient at low power output, and a diesel engine is least efficient there. A collection route operates almost entirely in that region.
Your idle share is the number the whole case rests on
50.62% is a research average across a sample. Some collection routes run well above it and some well below, and the difference decides whether electrification pays on your operation or only in general. In thirty minutes we will set up idle and stop capture on the diesel trucks you already run, so the comparison starts from your data.
The Eight Cost Components, and Which Ones Move
Argonne's framework splits total cost of ownership into eight components. The honest exercise is not to total them but to ask which the refuse duty cycle changes, and which you can measure for yourself. Swipe the table sideways on mobile.
| Cost component | Direction on a refuse cycle | Why | Can you measure it yourself? |
|---|---|---|---|
| Vehicle purchase price | Against you | The acquisition premium is the single largest obstacle and no duty cycle argument removes it. | Invoice, known on day one |
| Fuel or energy | Strongly for you | The idle share and low average power are exactly where diesel is least efficient. This is the component the refuse cycle moves most. | Yes, per unit per shift |
| Maintenance and repair | For you | Argonne scales battery electric repair cost at 60% against 100% for a diesel equivalent, and 2.68 stops per mile under regen is materially less friction braking. | Yes, from your own work orders |
| Insurance | Roughly neutral | Driven by the vehicle value and the operation rather than the powertrain. | Yes, from your policy |
| Taxes and fees | Varies | Jurisdiction-specific, and the direction depends entirely on local incentives and road-use charging. | Yes, locally |
| Infrastructure | Against you | Depot charging is real capital that a diesel fleet does not spend. It is also shared across the units that use it. | Partly, once installed |
| Labour and downtime | Unknown at the outset | Depends on charging windows against your route hours, and on how much work has to go back to the dealer. | Yes, and it is the one most often missed |
| Residual value | Genuinely uncertain | Thin resale history for electric refuse units, so any figure in a vendor model is an assumption rather than a market price. | Not yet |
Five of the eight are measurable from your own operation inside a year. One is partly measurable. Two are not: the acquisition premium is whatever the invoice says, and residual value for electric refuse units has very little market history behind it. Any model that produces a confident total is making an assumption about that last one, and it is worth asking which.
What the Published Research Does and Does Not Say
Worth being precise here, because refuse-specific numbers are quoted loosely and the underlying evidence is thinner than the confidence around it.
What is well established is the duty cycle itself and the direction it pushes. NREL has measured the idle share and stop density. CARB's analysis found that "significant savings are shown for battery-electric in the walk-in van, refuse truck, and day cab categories, even in the early years" — refuse named explicitly among the three. Argonne's repair-cost scaling puts a battery electric powertrain at 60% of a comparable diesel.
What is not well established is a per-mile total for a battery electric refuse truck. The detailed comparison tables in the heavy-duty literature concentrate on long-haul, delivery and drayage; refuse tends to appear in the qualitative findings rather than the itemised figures. NREL's dedicated Class 8 refuse study models hydrogen fuel cell rather than battery electric, putting fuel cell refuse trucks at cost parity with diesel in 2030 and with CNG in 2040 — useful, but a different powertrain and a projection rather than an observation.
So the position to take into a procurement decision is that the mechanism is solid and the arithmetic of your own routes is knowable, but a published per-mile figure for your exact application does not exist. Which makes the trial fleet the real source of evidence, and makes what you record during it the deliverable.
What Electrification Does Not Touch
Easy to lose in a powertrain conversation, and it matters for the size of the saving you should expect.
On a refuse truck the right column is a large share of the vehicle and a large share of the maintenance hours. Argonne's 60% scaling applies to the powertrain, not to the whole unit — so a projection that applies it to your entire maintenance budget will overstate the saving, possibly by a lot. The body does not care what turns the wheels.
Why the Route Day Happens to Suit Depot Charging
One structural advantage of collection work that rarely makes it into the cost discussion, and it is worth more than it looks.
A collection route is close to the ideal shape for depot charging. It is a single shift, it starts and finishes at the same yard, the mileage is modest and predictable, and the vehicle sits idle overnight in a fixed location. Compare that with a tractor unit that may be anywhere in three states at the end of a day. Range anxiety, which is the hardest objection to answer on most electric truck applications, is substantially easier to answer on a route that runs the same distance from the same yard every day.
That predictability also means charging can usually be scheduled into the cheapest hours rather than whenever the truck happens to return. The caveat is that it only holds while one vehicle has one shift. Fleets running two shifts off the same unit, or routes that extend seasonally, lose the overnight window and the calculation changes — so the question to settle early is whether any of your routes are shared between shifts.
How FleetRabbit Handles This
Four things, aimed at producing a cost case out of your own operation rather than a vendor's model.
The whole economic case rests on how much of your shift is stationary. NREL's 50.62% is a research average; your routes have their own number, and it is the first thing worth knowing.
Fuel, energy, parts, labour and downtime recorded the same way for both, so the comparison is between two of your own trucks rather than between your truck and a vendor's spreadsheet.
The regen saving shows up as pads and drums not replaced. That only becomes visible if brake work is recorded as its own line rather than folded into a service visit.
Five of the eight are measurable from your own operation within a year. Residual value is not. Keeping them apart is what makes a TCO case defensible.
Questions Waste Fleets Ask
Why is refuse considered the best case for electrification?
Because the duty cycle is where diesel is weakest. NREL measures refuse collection at 50.62% idle and 2.68 stops per mile at an average 21.26 mph, and an electric drivetrain is most efficient at exactly that low power output while a diesel engine is least efficient there. Review your routes.
What is the actual payback period?
It depends on your acquisition premium, your energy cost and your idle share, and anyone quoting a single figure without those three is guessing. The honest route is to measure the idle and stop profile on the diesel trucks you run now, then apply your own energy and purchase numbers. Set up the measurement.
How much maintenance saving should we expect?
Argonne scales battery electric powertrain repair cost at 60% against 100% for diesel, which is a powertrain figure rather than a whole-vehicle one — body, hydraulics, tires and the packer body are unchanged. On a 2.68-stop-per-mile cycle the brake saving from regen is likely to be the clearest single line. Track it per unit.
Does the packer body change anything?
It is a significant load either way and it is worth modelling separately, because a body drawing from the traction battery is competing with range in a way a diesel power take-off does not. Ask how the body is powered and what it costs in range on a full route. Record body loads.
Is electric better than CNG for refuse?
Both beat diesel on this duty cycle and they differ in where the cost sits: CNG in fuelling infrastructure and certified cylinder inspection, electric in charging capital and high-voltage qualification. NREL's modelling puts fuel cell refuse at parity with CNG only around 2040, which tells you CNG remains a strong incumbent here. Compare the options.
What should we record during a trial?
Energy or fuel per route, idle hours, stop counts, every work order with its parts and labour separated, brake work as its own line, and downtime hours including time waiting to charge. Those five produce a defensible cost per mile. Residual value will not be knowable and should be left as a stated assumption. Start the trial record.
Can we run the comparison alongside our diesel trucks?
That is the only way it carries weight. Same routes, same recording method, same cost categories, both powertrains on one maintenance record so the difference is between two trucks rather than between a truck and an estimate. Track Refuse Costs Free.
Build the Business Case From Your Own Routes
FleetRabbit records idle hours, energy and fuel, work orders with parts and labour split out, brake work as its own line and downtime including charging waits — for diesel, CNG and electric units side by side. So the cost per mile you take to a budget meeting is measured rather than modelled.
