Switching to an electric vehicle isn’t just about range and charging speed, it’s also about understanding how electricity pricing works.

One of the biggest advantages of EV ownership in Ireland is the ability to charge at home for significantly less than the cost of petrol or diesel. But to maximise those savings, it’s important to understand time-of-use electricity tariffs and how they work.

Here’s what every EV driver should know.

What Are Time-of-Use (TOU) Electricity Tariffs?

Time-of-use tariffs, sometimes called time-of-day tariffs, are electricity pricing plans where the cost per kilowatt-hour (kWh) changes depending on the time you use it.

The idea is simple:

Electricity is more expensive when demand on the grid is high, and cheaper when demand is low. Energy providers encourage households to shift usage, including EV charging, to off-peak hours, typically overnight.

For EV owners, this creates a real opportunity to reduce charging costs without changing driving habits.

When Are Peak and Off-Peak Hours in Ireland?

While timings vary slightly between providers, electricity pricing is generally broken into three periods:

• Peak hours – Usually early evening, when households are cooking, heating homes, and using appliances. Electricity demand and pricing is highest during this time.
• Off-peak hours – Typically late at night and early morning, when demand is lower and electricity rates drop significantly.
• Shoulder periods – A mid-range pricing window between peak and off-peak.

For most EV drivers, off-peak charging overnight is the most cost-effective strategy. It also helps reduce strain on the national grid during busy periods.

How Much Can You Save by Charging at Night?

The difference between daytime and night-time electricity rates can be significant.

While exact figures depend on your supplier, a typical example might look like this:

• Daytime rate: Around 18–20 cent per kWh
• Night rate: Around 9–10 cent per kWh

That’s close to a 50% reduction in cost simply by charging at night.

Over the course of a year, that difference can add up to substantial savings, particularly for drivers covering higher annual mileage.

Night rates commonly apply between approximately 11pm and 8am, though you should always confirm exact timings with your provider.

Do Public Chargers Offer Cheaper Night Rates?

At present, most public charging networks in Ireland operate on fixed pricing structures, meaning the cost per kWh doesn’t vary depending on the time of day.

Public AC charging is typically priced significantly higher than home off-peak electricity. Rapid DC charging costs more again due to the infrastructure involved.

This is why home charging, especially overnight, remains the most cost-effective way to run an EV for the majority of Irish drivers.

Public charging is incredibly useful for longer journeys, but it’s not usually the cheapest option for everyday use.

How to Schedule Charging for Off-Peak Hours

The good news is that setting up overnight charging is straightforward.

Most modern EVs and home wallboxes support scheduled charging. You can usually:

• Set a timer directly through the vehicle’s infotainment system
• Use your charger’s built-in scheduling feature
• Manage charging times through a companion smartphone app

Once scheduled, your car will automatically begin charging when off-peak rates apply. If you’re using a basic three-pin plug, a timer socket can be used in some cases, but a dedicated smart wallbox offers better efficiency, safety, and control.

Smart chargers also monitor battery levels and stop automatically when the car is fully charged, ensuring energy isn’t wasted.

Choosing the Right Electricity Plan

Not all energy plans are equal. Some suppliers offer EV-specific tariffs with extended night-rate windows or discounted charging periods.

If you’re considering switching to an electric car, it’s worth:

• Comparing electricity providers
• Reviewing peak and off-peak timings
• Calculating potential annual savings
• Asking about EV-focused plans

A small change in tariff can make a noticeable difference over time.

The Nevo Takeaway

Understanding electricity pricing is one of the simplest ways to maximise the financial benefits of EV ownership.

By aligning your charging routine with off-peak rates, you can significantly reduce running costs without changing how you drive.

For most Irish EV drivers, the formula is straightforward:

Charge at home, charge overnight, and let the savings build up quietly in the background.

If you’re planning the move to electric, don’t just compare cars, compare electricity plans too. It’s one of the smartest steps you can take.
