Electricity cost per mile for electric delivery fleets

If you manage an electric delivery fleet — or you're planning the switch from diesel — the single number that determines whether electrification saves or costs you money is electricity cost per mile. Get it wrong, and your "clean fleet" quietly bleeds cash. Get it right, and you unlock fuel savings of 60–80% compared to diesel, turning every route into a margin opportunity.

The problem is that electricity cost per mile for electric fleets isn't one number. It ranges from $0.03 to $0.12 per mile depending on your charging strategy, tariff structure, time of day, and whether you're using on-site solar or battery storage. That's a 4x spread — and most fleet operators land somewhere in the middle without realizing how much they're leaving on the table.

This guide breaks down exactly what drives your electricity cost per mile, how different charging strategies compare, and what smart fleet operators do to push their costs to the bottom of that range.

What is the electricity cost per mile for an electric delivery fleet?

The electricity cost per mile for an electric delivery fleet typically ranges from $0.03 to $0.12, depending on vehicle efficiency, electricity rates, charging strategy, and time-of-use tariffs. For comparison, diesel delivery vans cost $0.15–$0.25 per mile in fuel alone, meaning even the most expensive electric charging scenario still undercuts diesel by a wide margin.

Here's how the math works. Most electric delivery vans — models like the Ford E-Transit, BrightDrop 600, or Mercedes eSprinter — consume between 0.4 and 0.6 kWh per mile under real-world delivery conditions (including stop-and-go driving, payload, and climate control). Multiply that consumption by your electricity rate, and you get your cost per mile.

At $0.10/kWh (off-peak or solar-sourced): 0.5 kWh × $0.10 = $0.05 per mile

At $0.18/kWh (average U.S. commercial rate): 0.5 kWh × $0.18 = $0.09 per mile

At $0.30/kWh (peak rate or public DC fast charging): 0.5 kWh × $0.30 = $0.15 per mile

That last number is the only scenario where electric approaches diesel parity — and it only happens when you charge at the worst possible times or rely on expensive public chargers. The takeaway: your charging strategy matters as much as the vehicle itself.

How electricity cost per mile compares to diesel

The cost advantage of electric delivery fleets over diesel is significant and consistent across vehicle classes. Here's how the numbers stack up:

These numbers align with what the U.S. Department of Energy and organizations like RMI have documented: electric commercial vehicles deliver 60–80% fuel cost reductions compared to their diesel equivalents. A 2026 EY–Eurelectric report estimated that transitioning Europe's corporate fleets could unlock up to €246 billion in cumulative operating cost savings by 2030.

For a small fleet running 20 electric delivery vans at 100 miles per day each, the difference between charging at $0.05/mile versus $0.10/mile is $36,500 per year. Scale that to 50 vehicles, and you're looking at over $90,000 in annual savings just from optimizing when and how you charge.

The five factors that determine your cost per mile

1. Electricity rate and tariff structure

Your utility rate is the single biggest input to your cost per mile. But commercial electricity pricing is rarely a flat number. Most business accounts face time-of-use (TOU) rates where electricity costs 2–3x more during peak hours (typically 4–9 PM) than during off-peak windows (late night through early morning).

A fleet that charges all vehicles the moment drivers return at 5 PM might pay $0.25–$0.35/kWh. The same fleet charging the same vehicles overnight at 11 PM might pay $0.08–$0.12/kWh. Same electricity, same vehicles, but half the cost per mile — just by shifting the schedule.

2. Demand charges

This is the hidden cost that catches most fleet operators off guard. Demand charges are based on your highest power draw (measured in kW) during any 15-minute interval in the billing month. When multiple chargers run simultaneously at full power, they create a demand spike that can add 30–50% to your monthly electricity bill.

Real-world data from fleet depots illustrates the impact clearly. A 25-vehicle bus depot running unmanaged charging hit a peak demand of 475 kW, resulting in roughly $5,700 per month in demand charges alone. After implementing smart charge management that staggered charging sessions and limited simultaneous draws, peak demand dropped to 190 kW — cutting demand charges to $2,280 per month and saving over $41,000 annually.

For delivery fleets, the principle is identical. If your 10 chargers all start at 50 kW simultaneously when drivers plug in, that 500 kW spike could cost you $5,000–$12,000 per month in demand charges alone, depending on your utility's rate. Stagger them intelligently, and you might never exceed 150 kW.

3. Vehicle efficiency

Not all electric delivery vans consume energy at the same rate. Factors that affect your kWh-per-mile consumption include:

• Payload weight — a fully loaded van consumes 15–25% more energy than an empty one

• Route profile — city stop-and-go driving with regenerative braking is often more efficient than sustained highway speeds

• Climate control — heating in winter can reduce range (and increase cost per mile) by 20–30%

• Tire pressure and aerodynamics — often overlooked, but properly maintained tires alone can improve efficiency by 3–5%

• Driving behavior — aggressive acceleration and hard braking waste energy that regenerative systems can't fully recover

Most electric delivery vans achieve 2.5 to 4.0 miles per kWh under real-world conditions. At the fleet average electricity rate of $0.14/kWh, that translates to $0.035–$0.056 per mile for the most efficient vehicles and routes.

4. Charging method and location

Where and how you charge has a direct impact on your per-mile cost:

• Depot charging (Level 2, overnight) — the lowest cost option at $0.08–$0.15/kWh depending on your commercial rate and time of use

• Depot charging (DC fast, daytime top-ups) — faster but more expensive, typically $0.15–$0.25/kWh plus higher demand charges

• Public fast charging — the most expensive option at $0.30–$0.60/kWh, sometimes higher, and should be reserved for emergencies or en-route top-ups only

• Solar-powered depot charging — effectively $0.00–$0.05/kWh marginal cost once panels are installed, dramatically reducing cost per mile

The blended average across all charging sources is what matters. UK fleet data from Rightcharge found that the average blended cost across their platform was 40p/kWh (roughly $0.50/kWh at exchange rates), translating to about 11p per mile — still significantly cheaper than diesel at 15p per mile. The lesson: even a mix of cheap and expensive charging still beats fossil fuel.

5. On-site solar and battery storage

This is where the biggest cost-per-mile reductions happen. Fleets with rooftop or carport solar panels can route surplus generation directly into vehicles during the day, effectively charging at near-zero marginal cost. Add battery storage, and you can bank cheap off-peak or solar energy for overnight charging sessions.

RMI research confirms that managed charging combined with distributed energy resources like solar and batteries can reduce fleet charging costs by up to 30% compared to unmanaged grid-only charging. A Paired Power case study documented a company saving $136,000 annually by integrating solar and battery storage into workplace charging for 50 vehicles.

For a delivery fleet, this means every kWh generated on-site and routed into a vehicle is a kWh you didn't buy at commercial rates — dropping your effective cost per mile closer to $0.03–$0.04.

How smart charging software cuts your cost per mile by 30–50%

The difference between a well-optimized electric fleet and an unmanaged one isn't the vehicles — it's the software. Smart charging management software can reduce electricity costs by 20–40% through automated scheduling, load balancing, and tariff optimization, according to industry benchmarks.

Here's what smart charging actually does to your cost per mile:

Tariff-aware scheduling

Smart charging platforms monitor time-of-use rates and automatically shift charging sessions into the cheapest windows. If your utility charges $0.28/kWh at 5 PM but $0.09/kWh at midnight, the software ensures vehicles charge at midnight while still guaranteeing every van is ready by 6 AM departure. No manual spreadsheets, no guesswork.

Demand charge management

By staggering charging across vehicles and limiting simultaneous power draw, smart charging prevents the demand spikes that inflate your bill. Instead of 20 chargers pulling maximum power at once, the software sequences them — ensuring total site demand stays within a target threshold you set.

Solar surplus routing

When on-site solar panels produce more energy than the building consumes, smart charging routes the surplus directly into plugged-in vehicles. This captures value that would otherwise be exported to the grid at low feed-in rates — turning wasted solar into free miles.

Vehicle readiness optimization

The software doesn't just charge cheaply — it charges smartly. By integrating with vehicle telematics and shift schedules, it knows which vans need a full charge by 5 AM and which ones don't depart until noon. Early departures get priority charging at any cost; late departures wait for the cheapest rates. Every vehicle is ready, and not a single kWh is wasted at premium rates.

SortGrid, an AI-powered energy management platform for small and mid-sized businesses, automates all four of these strategies from a single dashboard — across every depot, every charger, and every vehicle. Instead of managing charging schedules manually or hoping your vehicles are ready in time, SortGrid coordinates EV charging, solar routing, battery storage, and tariff optimization automatically. The result is electricity cost per mile pushed toward the bottom of the range without any operational complexity.

Real-world cost per mile: what fleets are actually paying

Theoretical calculations are useful, but real-world fleet data tells the complete story.

Frito-Lay deployed 25 Ford E-Transit electric vans at its Manteca, California distribution center and reported a 45% reduction in last-mile delivery costs compared to its diesel fleet. The combination of lower fuel costs, reduced maintenance, and optimized route efficiency contributed to the savings.

Qmerit reports that across its network of commercial EV fleet installations, operators achieve 3 to 4 miles per kWh at an average electricity rate of $0.17/kWh, translating to $0.04–$0.05 per mile — roughly one-quarter of the equivalent diesel cost.

FleetRabbit analysis of Class 8 electric semi-trucks found electricity costs of approximately $0.25 per mile (at $0.12/kWh and 2.1 kWh/mile), compared to $0.47 per mile for diesel at $3.50/gallon — a 47% per-mile fuel savings even for the heaviest vehicle class.

These examples share a common thread: the operators achieving the lowest cost per mile are the ones investing in charging infrastructure optimization, not just plugging vehicles into the wall and hoping for the best.

How to calculate your fleet's electricity cost per mile

Here's a simple framework to estimate your own fleet's cost per mile before and after optimization:

1. Find your vehicle's energy consumption rate. Check the manufacturer's spec sheet or your telematics data for kWh per mile. For electric delivery vans, plan on 0.4–0.6 kWh per mile under real-world conditions.

2. Determine your blended electricity rate. Average your actual electricity costs across all charging — including time-of-use rates, demand charges, and any solar offset. Divide your total monthly electricity bill allocated to EV charging by total kWh consumed.

3. Multiply consumption by rate. If your vans consume 0.5 kWh/mile and your blended rate is $0.14/kWh, your cost per mile is $0.07.

4. Estimate optimization potential. If you're not using smart charging, apply a 20–40% reduction to your blended rate to estimate what managed charging, demand charge optimization, and solar integration could deliver.

5. Calculate annual fleet savings. Multiply the per-mile reduction by daily miles per vehicle, number of vehicles, and 365 days. For a 20-van fleet averaging 100 miles/day, even a $0.02/mile improvement equals $146,000 in annual savings.

What about maintenance and total cost of ownership?

While this article focuses on electricity cost per mile, it's worth noting that fuel savings are only part of the picture. Electric delivery vans also deliver 25–40% lower maintenance costs than diesel equivalents, thanks to fewer moving parts, regenerative braking that reduces brake wear, and no need for oil changes, exhaust treatment, or transmission servicing.

Combined, fuel and maintenance savings for electric commercial vans now deliver up to 13% lower total cost of ownership (TCO) than diesel equivalents, according to 2026 fleet management data. With battery pack prices falling to $108/kWh in 2025 — an 8% year-over-year decline — the upfront cost gap continues to narrow while the operating cost advantage widens.

The bottom line: your charging strategy is your cost strategy

The electricity cost per mile for electric delivery fleets isn't fixed — it's a variable you can control. The spread between $0.03 and $0.12 per mile comes down to decisions you make about when you charge, how you manage demand, and whether you integrate solar and storage into your depot infrastructure.

Fleets that plug in vehicles at random and charge on whatever tariff happens to apply will land at the expensive end of the range. Fleets that use smart charging software to optimize schedules, flatten demand peaks, and route solar surplus into vehicles will consistently operate at $0.04–$0.06 per mile — saving tens of thousands of dollars annually compared to both unmanaged electric charging and diesel.

If your team is spending hours juggling charging schedules across depots, guessing whether vehicles will be ready for the morning shift, and watching electricity bills climb from demand charges you didn't anticipate — SortGrid automates it all from a single dashboard. Connect your chargers, set your shift schedules, and let the platform optimize every charging session across every site, so every mile runs at the lowest possible energy cost without the complexity.
