To calculate whether switching a South African fleet to electric vehicles (EVs) makes financial sense, compare an EV with a genuinely equivalent petrol or diesel vehicle over the same service life and work profile. Include vehicle and financing costs, energy, maintenance, insurance, charging equipment and site upgrades, then subtract expected resale value. There is no universal South African break-even point: published local results use different vehicles, tariffs and assumptions, so fleet-specific quotes and route data are essential.
Build a like-for-like lifetime-cost calculation
Choose the same evaluation period and required service for both vehicles. Match vehicle class and capability, then model the routes, payload, mileage, utilisation and shift pattern the fleet actually needs to serve. A delivery van should not be compared with a passenger car simply because both are electric or petrol-powered.
A practical calculation is:
Discounted lifetime cost = acquisition or financed cost + discounted operating costs + allocated charging and implementation costs − residual value.
Itemise operating costs such as fuel or electricity, maintenance, insurance and other fleet-specific expenses. State whether amounts are nominal or inflation-adjusted, how finance is treated, the discount rate, tax assumptions and the method used to estimate residual value. Avoid counting both the full vehicle capital cost and financing principal as separate costs.

City Energy’s report states its method as “Capital cost + ((Maintenance cost + Energy cost) / (1 + Discount Rate) ^ Number of years).” That expression is the report’s formula, not a complete fleet TCO model: it does not by itself cover every category above. South African public-sector procurement guidance likewise calls for considering vehicle capital, finance, insurance, maintenance and fuel over its life, alongside charger and implementation choices. City Energy’s report and the public-sector EV procurement guide provide useful starting points.
Collect these inputs before comparing vehicles
- Vehicle and ownership: EV and equivalent ICE purchase or lease quotations, taxes, finance terms, expected service life and residual value.
- Work profile: actual daily routes and distances, payload, utilisation, idle time, shift length, depot-return patterns and the range reserve required.
- Energy: current delivered fuel cost and fleet consumption; candidate EV consumption measured or conservatively estimated for comparable duty; electricity tariff by time and billing period, demand charges, charging losses and any solar or wheeled-energy assumptions.
- Charging: charger count and type, site electrical capacity, installation and upgrades, software, maintenance, operating arrangement and the number of vehicles sharing the equipment.
- Other costs and conditions: insurance, maintenance plans, downtime, staff training and any tax or incentive treatment confirmed for the particular fleet.
The procurement guide also recommends checking required range and vehicle function, urban versus rural use, model availability, storage, whether power will be supplied on site or en route, load management, charger location and coordination with the utility.
Cost the depot charging system, not just the vehicle
Charging infrastructure can include hardware, electrical work, site-capacity upgrades, software and ongoing operation. Record installation and implementation costs separately from vehicle costs, then allocate them across the vehicles and years that will use them. Show the allocation method: for example, a charger shared among several vehicles should not be charged entirely to just one vehicle in a fleet comparison.
Use the actual depot tariff and connection details. A household electricity price or a public charging price is not a substitute for the site’s commercial tariff, applicable demand charges and expected charging schedule. If vehicles can charge outside peak periods, model that schedule only if their route and shift requirements allow it.

Charger selection depends on compatible vehicles and connectors, site capacity, duty cycle and how long vehicles are parked. A procurement decision should also specify who owns and maintains the equipment, which software or tools are required, and whether charging is on site, en route or a mix. Eskom said in a 10 September 2025 announcement that smart charging and time-of-use tariffs were being developed; that announcement is not confirmation that a particular depot can access a specific tariff. Eskom’s announcement is dated and should be treated as a statement of plans, not a current tariff offer.
Test the assumptions that can change the result
Run a base case and at least one plausible high- and low-cost case. Keep the EV and ICE service requirement constant while changing the inputs most likely to affect your fleet’s result.
| Input to vary | What to test |
|---|---|
| EV purchase premium and finance | Use current vehicle quotations and the fleet’s actual lease or financing terms; show the effect of the acquisition premium separately. |
| Annual kilometres and utilisation | Use measured route data, then test lower or higher mileage and utilisation. Energy savings per kilometre matter more when vehicles travel farther, but the purchase premium and other costs still count. |
| Fuel and electricity prices | Use delivered fleet fuel costs and the depot’s applicable tariff, billing periods and demand charges. Test alternative charging times only where operations make them feasible. |
| Charging utilisation and site costs | Vary the number of vehicles sharing chargers, expected charging demand, installation costs and any electrical upgrade required. |
| Service life and residual value | Test the years the fleet expects to keep each vehicle and use evidence-based resale assumptions rather than treating resale value as certain. |
| Maintenance, insurance and downtime | Use fleet-specific quotes or records for both vehicle types; do not assume that any one category is negligible. |
The model should make its financing and tax treatment visible. The procurement guide flags incentives as a consideration, but the evidence cited here does not establish current incentive eligibility for an individual fleet. Confirm applicable treatment with the relevant tax or procurement advisers before including it as a saving.

- WORKS WITH EVERY NON-TESLA EV: Standard J1772 connector plugs straight into Ford, Chevrolet, Hyundai, Kia, Nissan, BMW, Volkswagen, Audi, Rivian, Lucid and every other EV or plug-in hybrid sold with a J1772 port - no adapter needed. Tesla drivers can charge too, using the J1772 adapter that comes with the car.
- PLUG IN, NO HARDWIRING: Level 2 charger delivers up to 40A to fully charge most EVs overnight. Plugs into a 240V, 4-prong NEMA 14-50 outlet (the RV/range type - NOT a dryer outlet) on a dedicated 50A circuit. The extra-long 25 ft cable easily reaches across a garage or driveway. Before ordering, check your car's port type and that you have the right outlet.
- CONTROL & SAVE FROM YOUR PHONE: A stronger built-in antenna keeps the charger online even in a garage or basement. Use the free app to start/stop charging, set speed (6-40A), get reminders, and track energy use and cost. Schedule off-peak overnight charging to cut your electric bill. Requires 2.4 GHz WiFi.
- SAFETY-CERTIFIED & WEATHERPROOF: Independently tested and certified (UL, ETL, FCC, Energy Star). A fully sealed IP66 / NEMA 4 housing stands up to rain, snow, heat and dust indoors or out, and internal steel shielding protects the electronics for years of reliable use.
- GLOW-IN-THE-DARK HOLSTER: The included high-visibility holster glows in the dark so you can find and dock the plug easily at night. Holds the connector securely when not in use.
City Energy: a historical model with higher EV TCO in its cases
City Energy’s report uses inputs relevant as at 2022. It found EV total cost of ownership (TCO) above that of mid-market ICE alternatives across the vehicle types it modelled, chiefly because of higher EV capital costs, and also identified insurance as an important cost driver. The report notes that capital prices, local manufacturing and tax regimes can change the outcome. It does not establish a national break-even mileage that can be applied to all fleets. Read the City Energy report for its scope and assumptions.
GreenCape: a seven-year Cape Town pilot comparison
GreenCape analysed five BMW i3 vehicles used by Cape Town Traffic Services from 2020 to 2022, supported by six City-owned charging stations, two of them solar-powered. Its comparator was five VW Golf GTI vehicles. The report’s stated assumptions and reported results are historical case figures, not current price guidance:
| Measure | BMW i3 EV | VW Golf GTI ICE |
|---|---|---|
| Purchase price assumed in GreenCape’s case | R608,755 | R587,951 |
| Energy or fuel-price assumption | Electricity at R2.30/kWh | Petrol at R22.30/litre |
| Consumption assumption | 0.199 kWh/km | 0.106 litres/km |
| Annual mileage assumption | 50,000 km | 50,000 km |
| Reported operating cost per kilometre | R0.35–R0.46 | R2.36 |
| Reported purchase plus operating cost over seven years | R768,950 | R1,415,281 |
These figures are GreenCape’s analysis of the Cape Town pilot data, published in 2023. They describe one vehicle pair, use assumptions specific to that analysis and should not be presented as a current fleet saving or a general EV-versus-ICE result. The GreenCape case study describes the pilot and its comparison.
The City Energy and GreenCape findings differ because they model different comparisons and assumptions: a 2022-input mid-market model is not the same case as a high-mileage i3-versus-Golf GTI comparison. Neither establishes what a particular fleet will spend in 2026. Obtain current quotations and use the fleet’s actual route, tariff and site estimates to calculate that result.

It is designed to operate in temperatures from −22°F to 122°F, supporting charging in garages, driveways, and changing outdoor conditions. Combining dual-voltage flexibility, a long cable, portable construction, and multiple safety protections, this EV portable charger works as a dependable everyday charger or a convenient backup charging solution.
Use a pilot to replace estimates with operating data
A limited pilot can show whether candidate vehicles fit the routes and charging windows, while improving the inputs for the next procurement decision. GreenCape’s Cape Town example used telemetry from five BMW i3 vehicles and six charging stations, demonstrating the value of recording vehicle and charging activity rather than relying only on catalogue assumptions.
Track during the pilot
- Distance, energy use and charging losses by vehicle and route.
- Payload, daily mileage, range reserve and whether each shift was completed as planned.
- Charging time, location, tariff period, charger use and any queues or access constraints.
- Downtime, maintenance, insurance costs and service experience.
- Any operational changes, such as route reassignment or charging outside the original plan.
Compare the pilot’s observed results with the baseline ICE fleet on the same work. Then update energy use, charger utilisation, downtime and service-life assumptions before using the model for a larger purchase.
Make the decision from the fleet’s own evidence
- Choose the service and comparator. Define the vehicle class, required capability, evaluation period and ICE alternative that can do the same work.
- Measure the duty cycle. Gather route distances, payloads, shift and depot-return patterns, utilisation and range requirements from fleet records.
- Get current commercial inputs. Obtain vehicle and finance or lease quotations, insurance and maintenance estimates, and the depot’s tariff and demand-charge details.
- Price charging and implementation. Request a site assessment covering charger compatibility, electrical capacity, installation, upgrades, software, operation and maintenance.
- Calculate and stress-test TCO. State discounting, financing, taxes and residual-value assumptions, allocate shared infrastructure transparently, and vary the material inputs in a sensitivity analysis.
- Pilot where uncertainty remains. Record energy, mileage, charging behaviour and downtime, then substitute observed values into the comparison.
A fleet should treat the result as a decision tied to its vehicles, routes, site and tariff—not as a national EV-savings rule. Eskom’s 10 September 2025 announcement also reported the launch of its first 20-vehicle EV fleet, a 2035 full-electrification target for its Distribution Division fleet, and plans for 55 public charging stations over the following two years. These are dated company announcements and plans, not evidence that all planned stations or tariffs are now available to another operator.
