What Is a Smart Meter?

Smart meters are transforming how Irish households manage energy, offering real-time insights, accurate billing, and a more sustainable future. This guide explains what a smart electricity meter is, how it works, and how it benefits you.

What is a Smart Meter

Smart meters are next-generation electricity meters that digitally measure your energy usage and communicate the data automatically to your energy supplier.

Definition and Purpose

A smart meter records your electricity consumption in near real-time and eliminates the need for manual readings. It enables both households and suppliers to better manage energy usage.

Difference Between Traditional and Smart Meters

Unlike traditional meters that must be read manually, smart meters send readings electronically. This means more accurate billing and the ability to track your usage by the hour.

Benefits of Smart Meters

There are so many advantages of smart meters compared to traditional energy meters. Here are just a few of them:

Accurate Billing

Smart meters help eliminate estimated bills. Energia receives exact data, so you’re only charged for what you use.

Real-Time Usage Monitoring

You can monitor your energy usage throughout the day, helping you understand when and how you consume electricity and make more informed choices.

Environmental Impact

By encouraging more mindful energy consumption, smart meters contribute to reducing Ireland’s carbon emissions and support the wider transition to renewable energy.

Smart Meter Rollout in Ireland

National Smart Metering Programme

The national rollout, led by ESB Networks, is part of a major infrastructure upgrade to support a more sustainable and digital energy future in Ireland.

Installation Timeline and Process

Installations began in 2019 and are continuing in phases. Customers are notified in advance and the process typically takes about 30 minutes with minimal disruption.

Your data is encrypted and securely transferred. Only authorised energy market participants can access it, and always in compliance with data protection regulations.

Accessing Your Energy Usage Information

Usage data is available via Energia’s online portal or mobile app, allowing you to view usage by time of day, identify patterns, and find opportunities to save.
