Electricity Rates Ireland (2026): Price per kWh & Standing Charges

Electricity rates in Ireland are made up of several different charges, including the electricity unit rate, standing charge and tariff structure.

Understanding these charges makes it easier to compare electricity plans properly and work out which tariff offers the best overall value for your household.

The lowest advertised electricity rate does not always mean the lowest annual bill.

What Are Electricity Rates?

Electricity rates are the charges that determine how much you pay for electricity.

The main components are:

Electricity unit rate – the price charged for each kilowatt-hour (kWh) of electricity used
Standing charge – a fixed daily charge applied to the electricity account
Tariff structure – whether your electricity is charged at one rate or different rates depending on the time of day

Your total annual electricity cost depends on how these charges interact with your household electricity usage.

What Is The Electricity Price Per kWh?

The price per kWh is the amount you pay for each kilowatt-hour of electricity consumed.

This is also commonly called the electricity unit rate.

For example, the more electricity your household uses, the greater the effect the unit rate can have on the total annual bill.

Electricity unit rates can vary depending on:

electricity supplier
tariff type
standard or smart pricing
day, night or off-peak periods
available discounts

A lower unit rate can be valuable, but it should always be considered together with standing charges and the full tariff structure.

What Is A Standing Charge?

A standing charge is a fixed daily charge applied to an electricity account regardless of how much electricity is used.

This means you can still pay a standing charge even during periods when very little electricity is consumed.

Standing charges vary between electricity suppliers and tariffs.

They can have a particularly noticeable effect on lower-usage households because the fixed charge represents a larger proportion of the annual electricity bill.

For higher-usage households, the electricity unit rate may have a greater impact on total annual cost.

This is why both unit rates and standing charges should be compared together.

Unit Rate Vs Standing Charge

It is possible for one electricity tariff to have a low unit rate but a relatively high standing charge.

Another tariff may have a slightly higher unit rate but a lower standing charge.

Which option is cheaper depends on how much electricity the household uses.

That means comparing one headline rate alone can be misleading.

The best comparison is usually based on the estimated total annual electricity cost.

Standard Electricity Rates

A standard 24-hour electricity tariff generally charges the same electricity unit rate throughout the day.

This can suit households where electricity consumption is spread relatively evenly and where there is limited ability to move electricity usage into cheaper time periods.

The total cost still depends on:

electricity unit rate
standing charge
annual electricity consumption
discounts and contract terms

Day And Night Electricity Rates

Day/night electricity tariffs use different electricity rates depending on when electricity is consumed.

They typically include:

Day rate – the electricity rate applying during daytime hours
Night rate – a lower electricity rate applying during designated overnight hours

These tariffs may suit households that can shift a meaningful amount of electricity usage into the cheaper night period.

Smart Electricity Rates

Smart tariffs can use several electricity rates depending on the time of day.

Typical pricing periods can include:

Peak rate – generally the most expensive electricity period
Day rate – the normal daytime electricity rate
Off-peak or night rate – a lower electricity rate during designated cheaper periods

The exact times and rates depend on the individual electricity tariff.

A very cheap off-peak electricity rate does not automatically mean the smart tariff has the lowest annual cost if peak or daytime rates are significantly higher.

Night Rate And Off-Peak Electricity Rates

Some electricity tariffs offer substantially lower electricity rates during overnight or other designated off-peak periods.

These rates can be particularly useful for households with flexible electricity usage.

This can include:

EV charging
home battery charging
some household appliances
other electricity loads that can be safely scheduled

The value of a cheap night rate depends on how much electricity is actually consumed during the lower-cost period.

How To Compare Electricity Rates Properly

When comparing electricity rates, households should review the complete electricity tariff.

Consider:

electricity unit rate
standing charge
annual electricity usage
day and night usage where relevant
peak and off-peak electricity rates
discount duration
contract terms
estimated total annual electricity cost

Comparing only the biggest supplier discount or lowest advertised unit rate can give an incomplete picture.

Electricity Rates For EV Owners

EV owners can have significantly higher electricity consumption because of home charging.

Lower overnight or off-peak electricity rates can therefore be particularly valuable.

However, the best EV electricity tariff should consider the complete household electricity profile rather than the EV charging rate alone.

Electricity Rates For Solar And Battery Homes

Solar and battery households can have very different electricity usage patterns from standard homes.

When comparing electricity rates, these households may need to consider:

grid electricity import rates
off-peak battery charging rates
peak electricity prices
standing charges
solar export payments

Electricity Rates For Heat Pump Homes

Heat pump households can use considerably more electricity than homes using other heating systems.

This means both the electricity unit rate and tariff structure can have a large effect on annual heating costs.

Why The Cheapest Electricity Rate Is Not Always The Best Deal

A plan with the cheapest advertised electricity unit rate may not always have the lowest total annual cost.

Other charges can affect the result, including:

standing charges
higher peak rates
higher daytime rates
short discount periods
contract conditions

This is why electricity plans should be compared using your actual usage and total expected annual cost.

Electricity Rates FAQs

What is an electricity unit rate?

The electricity unit rate is the price charged for each kilowatt-hour (kWh) of electricity used.

What does price per kWh mean?

Price per kWh is another way of describing the electricity unit rate. It tells you how much you pay for each unit of electricity consumed.

What is a standing charge?

A standing charge is a fixed daily electricity-account charge that applies regardless of how much electricity you use.

Is a lower electricity unit rate always cheaper?

No. Standing charges, tariff structure, peak rates and annual electricity consumption can mean another tariff has a lower total annual cost.

What is the difference between electricity rates and electricity prices?

An electricity rate usually refers to the charge for a unit of electricity, while the overall electricity price paid by a household also includes standing charges, tariff structure and electricity usage.

Are night electricity rates cheaper?

On tariffs with a designated night or off-peak period, the night electricity rate is usually lower than the corresponding daytime or peak rate.

Are smart electricity rates cheaper?

They can be for households that move enough electricity usage into lower-cost periods, but they are not automatically cheaper for every household.

How should I compare electricity rates?

Compare unit rates, standing charges, tariff structure, annual electricity usage and the estimated total annual cost rather than focusing on one advertised rate alone.
