What is a Time-of-Use tariff?
A way to save money on your energy bill and contribute to cleaner energy production in Ireland. Time-of-Use (ToU) tariffs are a new way for homes with Smart Meters to pay for electricity.
You pay different rates at different times of day. This differs from a traditional ‘flat’ tariff, which charges the same rate at all times of day. ToU tariffs reflect the amount of electricity used at different times.
Usage is low at night and highest in the late afternoon, when people return from work and many businesses are still open. It costs more to provide electricity during these peak hours.

Key Facts about ToU tariffs
- You can take advantage of cheaper hours
By shifting when you use electricity from more expensive to cheaper times, you can lower your bill.
- You have more control over your bill
How much you save will depend on whether you change your habits and use appliances that need a lot of energy at night instead of at peak times.
- You contribute to cleaner energy production
Using your electricity at night means that a larger share can be produced by renewable sources.
