What Is an ESB Smart Meter?

Smart meters work by transmitting real time information to your electricity provider ensuring that you get accurate and detailed billing for your energy consumption. There are three different rates for customers using a smart meter, a day rate, a higher peak rate and a lower night rate. The incentive is to change your electricity consuming habits in order to avail of the cheaper night rate and thereby reduce your electricity bills.
What Is a Smart Meter?
Smart meters are digital devices that track your electricity use and send data to your supplier.
They provide accurate billing, help you understand your consumption, and allow you to take advantage of cheaper off-peak rates.
Simply put, a smart is a type of electricity meter is a device that counts your electricity usage in real-time and wirelessly relays that information to your energy provider.
This allows you to have up-to-the-minute control over your electricity consumption, intended to help reduce electricity usage in your home.
Having a smart meter eliminates the need to submit meter readings which means that you shouldn't be overcharged on your energy bills that can sometimes happen when your usage is estimated.
Your smart meter transmits your electricity usage wirelessly via a secure 2G mobile phone network, provided by Three Ireland Limited.
The technology used in the ESB smart meter-supplier communications employs multiple layers of cybersecurity and complies with all applicable data privacy and protection laws.
What are Smart Tariffs and Time-Of-Use Tariffs?
Unlike standard electricity tariffs, smart meter tariffs offer different prices for electricity throughout the day. These are known as Time-of-Use tariffs.
These tariffs are designed to encourage consumers to avoid using electricity at peak times and shift their usage to cheaper nightime rates.
There are various types of smart tariffs available to homeowners;
- Standard Smart Tariff
- Weekend Smart Tariff
- 24 hour Smart Tariff
All suppliers are required to offer a Standard Smart Plan with three unit rates:
Unit Rate | Time | Price |
---|---|---|
Day | 08:00 - 17:00 | €€ |
Peak | 17:00 - 19:00 | €€€ |
Night | 19:00 - 23:00 | €€ |
EV | 23:00 - 08:00 | € |
Special smart meter tariffs are also available for electric vehicle owners that offer an extra-low, nighttime rate for charging your electric vehicle.
Some suppliers also offer free weekend electricity as part of their smart tariffs.

Through your account, you can view details of your electricity usage to help you understand and manage your consumption.
To sign up, all you need to do is visit the ESB Networks Account registration page and submit the following details:
- Email address
- MPRN number
- Mobile number
Once signed up, you will be able to access your smart meter information including:
- Charts showing your electricity usage over a week, which you can also switch between daily, monthly, or yearly views through the drop-down menu above the chart.

- The data is updated regularly, but it may take 36–48 hours for data to appear on your online account.
How Do You Read an Esb Smart Meter?
Every smart meter has a digital screen from which you can select the display option of your choice. Simply push the large black button on the left-hand side and scroll between display options.
Your cumulative meter reading should be the number displayed in the centre of the digital screen.

Here is the information found from the default display:
- Shows the cumulative kWh usage for a 24-hour period
- Current Time-Of-Use tariff (i.e. T1, T2, T3) for day, night, or peak tariff
- Meter signal strength
- Voltage and the direction of feed (import or export for those selling back energy produced from their solar panels, windmill, or another source).
Do not confuse smart meters with electricity monitors, or In-Home Display (IHD) monitors. Currently, we know of two electricity suppliers, Electric Ireland and Pinergy, who provide IHDs with their smart meter plans.
By looking at an electricity monitor, you'll be able to see how much energy you are consuming and how much you are spending, in near real-time. Roughly the size of a smartphone, you can place the device anywhere you like in your house.
