Smart meter tariffs: What to know in 2026

In this guide, we explain the basics of smart meters, their benefits, and how Energia’s smart meter tariffs can help you save money and reduce energy usage.

As part of Ireland’s Climate Action plan, over 2 million smart meters have already been installed to support smart grids, electric transport, heating, and local renewable energy. These devices provide real-time data, helping you manage your consumption, reduce energy waste, and save money. When paired with the right tariff, you can use electricity during off-peak hours at lower rates, helping you save more money.

How smart meter installation works

The smart meter installation process in Ireland is simple. Here’s how it typically works:

1. Installation notice: You will receive a letter with your installation date, and if your meter is inside, someone will need to be home to provide access. The installation is free and carried out by ESB Networks across Ireland.

2. Meter replacement: During the installation, the technician will remove your old meter and install the new smart meter. For safety reasons, your electricity will need to be turned off for about 45 minutes while the work is done. The technician will make sure everything is working properly and that your new meter is connected to your energy supplier. If you’re new to smart meters, check out our guide on how to read a smart meter to understand your digital display and usage data.

3. Setup and testing: After the smart meter is installed, it will automatically begin sending your usage data to your energy supplier. The technician will test the system to make sure everything is working correctly.

4. Post-installation support: If you have any questions or concerns after installation, ESB Networks can carry out any necessary follow-up work at no extra cost to you. Before exploring smart tariffs, it’s helpful to understand the pros and cons of smart meters, including their benefits like accurate billing and energy savings, as well as potential downsides such as peak-time costs and adjustment periods.

Smart meter tariffs, explained

Smart meter tariffs are designed to help you save money by offering different options based on when you use energy. You can check out Energia’s smart meter electricity plans to learn more about our tariffs that best suit your needs.

Here's a breakdown of how they work:

What is a smart meter tariff?

A smart tariff or smart meter tariff is a pricing plan designed for homes with smart meters, offering different electricity rates depending on the time of day. If you’re new to smart tariffs, it helps to first understand what a smart meter is and how it records your electricity usage. These tariffs allow you to save money by using energy during off-peak hours when demand is lower. Running appliances during cheaper off-peak hours, like at night, can help lower your electricity bills. Since June 2026, dynamic electricity tariffs have been available in Ireland, including Energia’s Smart Track tariff, where electricity prices can change every half hour based on wholesale market rates. This type of tariff may suit households with flexible energy usage, such as those charging an EV, using solar panels, or managing solar battery storage, as they may be able to shift consumption or battery charging to lower-cost periods and use stored energy when prices are higher.

Energia’s smart tariff rates give you more control over your energy use, allowing you to take advantage of lower prices when demand is low. This cuts your costs while making energy use more efficient for everyone.
