EV vs Petrol and Diesel in Nigeria: Energy, Parts and Ownership Costs

An EV can have a strong running-cost advantage when it charges from reasonably priced grid electricity. That advantage can shrink or reverse against a particular petrol vehicle if most charging comes from an expensive generator. The right comparison includes the energy source, route, servicing, parts, downtime and purchase price.

This guide uses actual published Nigerian energy-price samples and clearly separates them from assumed vehicle consumption. It does not claim that a particular Ruichi model has been road-tested against a named petrol or diesel vehicle.

Our sources and the dates behind the numbers

• Grid: ₦209.50/kWh, A–Non-MD, and ₦62.48/kWh, B–Non-MD, in NERC’s September 2026 IE order, Table 3, page 7. The end-user section covers the yet-to-be-transitioned Ikeja franchise area in Ogun State. These are published energy rates before separately applied taxes or billing charges, not rates for every Nigerian customer.
• Petrol: ₦1,596.25/litre, national average in the NBS May 2026 PMS report.
• Diesel: ₦3,277.47/litre, national average in the NBS May 2026 AGO report.

Sources were checked on 28 September 2026. The tariff and fuel observations have different reference months. This is a transparent dated sample, not a claim about today’s price at your meter or filling station. Substitute your receipts when making a purchase decision.

Compare the same job

We assume 3,000 km per month, EV electricity use of 25 kWh per 100 km measured at the charging supply, petrol consumption of 12 litres per 100 km and diesel consumption of 10 litres per 100 km. These are scenario inputs, not manufacturer specifications. The EV input already includes charging energy drawn from the supply; no additional charging-loss percentage is added.

Use vehicles with comparable legal payload, seating, body type and route capability in your own comparison. A smaller electric van and a larger diesel truck are not interchangeable simply because both carry goods.

*Five-year columns hold the sample prices and consumption constant to expose the arithmetic. They are not price forecasts or total ownership costs. Totals use unrounded rates. At the Band A sample, the calculated monthly energy difference is ₦417,525 versus the petrol scenario and ₦826,116 versus the diesel scenario, before other costs.

Generator charging changes the comparison

Our generator guide uses published Cat DE22E3 consumption and the same NBS diesel price. At its 75% prime-load point, calculated fuel-only electricity cost is ₦1,065.18/kWh. At the assumed EV consumption, that is ₦266.29/km, or about ₦798,883 per month before generator maintenance and depreciation.

That generator-powered EV scenario costs more in energy than the petrol scenario above, though less than the diesel scenario. If 80% of charging energy came from the Band A grid sample and 20% from that generator-cost point, weighted electricity cost would be about ₦380.64/kWh and vehicle energy cost about ₦95.16/km. Source shares must be measured in energy, not just hours of generator operation.

The fuel-only break-even electricity price against the petrol scenario is ₦191.55 ÷ 0.25 = ₦766.20/kWh. This is a useful threshold for evaluating an estate’s or depot’s charging charge. It excludes purchase price and maintenance, so it is not a total-cost break-even point.

Servicing: fewer engine tasks, but not zero maintenance

A battery-electric vehicle has no combustion-engine oil change, spark plugs or exhaust system. Tyres, suspension, steering, brakes, air conditioning and model-specific cooling and auxiliary systems still need attention. The Department of Energy’s maintenance guidance explains the lower routine-maintenance burden of all-electric vehicles, including the effect of regenerative braking. It does not establish Nigerian labour prices or a fixed percentage saving for these vehicles.

Parts availability can matter as much as parts price

Ask for quotes for a small basket of likely consumables and repair parts before committing to a fleet. Do not assume that a part inexpensive in China is inexpensive and immediately available in Nigeria. Freight, lead time, diagnostic capability and the cost of an idle vehicle all affect the decision.

For a tyre budget, divide the fitted cost of a complete set by the expected kilometres before replacement. For scheduled servicing, multiply the applicable visits by the quoted service cost. Use the manufacturer’s intervals and your operating conditions; do not invent identical intervals for both powertrains.

Build the total-cost worksheet

Total ownership cost = purchase and setup + energy + maintenance and repairs + insurance and other operating costs + financing + downtime cost − resale proceeds. Use the same period and distance for both options. Keep a battery-repair or replacement scenario visible rather than assuming either zero risk or an automatic full replacement in year five.

We have not published fabricated Naira parts prices, installation quotes or resale values. Obtain those model-specific inputs and then calculate the decision. For illustration of the method, an actual quoted upfront premium divided by a measured annual net operating saving gives a simple payback period; if the net saving is zero or negative, that calculation does not produce a payback.
