Energia is one of the most interesting energy suppliers in the Irish market. Where Electric Ireland has brand recognition and Bord Gáis Energy has gas heritage, Energia has built its retail offering around smart metering, time-of-use tariffs, and digital account management — positioning itself as the technology-forward choice for Irish energy customers.
Who Is Energia?
Energia is part of the Energia Group, a major independently Irish-owned energy company with operations across generation, renewable energy development, and retail supply. Unlike Electric Ireland (part of the ESB Group) or Bord Gáis Energy (owned by Centrica), Energia is an independently listed Irish business.
Crucially, Energia is a significant generator of wind energy in Ireland — it owns and operates wind farms rather than simply purchasing green energy certificates. This means its green electricity credentials go beyond the standard REGO (Renewable Energy Guarantee of Origin) certificates that any supplier can buy on the wholesale market.
Energia supplies both homes and businesses, with particular focus on smart tariff innovation and online switching.
Energia's Electricity Tariffs
Standard electricity tariffs: Energia offers competitive new customer discounts on their standard electricity unit rates. These are typically among the sharper deals in the market, particularly for customers who switch online, where an additional online-switch discount often applies.
Smart Home tariff (time-of-use): This is where Energia differentiates itself. Their Smart Home tariff uses smart meter data to charge you different rates depending on when you use electricity. Night rates (typically 11pm–8am) are significantly lower than day rates, with peak hours priced higher. For households that can shift usage to off-peak times — running the dishwasher or washing machine overnight, setting the immersion on a timer, charging an EV at night — the annual savings can be meaningful.
EV tariff: Energia offers a specific tariff for electric vehicle owners with very competitive overnight rates designed for when most EVs charge. If you drive an EV or are planning to buy one, this is among the most relevant tariffs on the Irish market.
Green electricity: As a major Irish wind energy generator, Energia's green electricity is backed by generation from wind farms in Ireland, not just certificates purchased on the open market.
Energia Gas Tariffs
Energia offers natural gas tariffs in addition to electricity, with new customer discounts and full online account management. Their gas rates are competitive but vary against rivals like Bord Gáis Energy and SSE Airtricity depending on current promotions.
For households using both fuels, Energia's electricity and gas combination can be worth comparing as a dual option — though taking two separate best-deal accounts from different suppliers sometimes works out cheaper than a bundle. Use our gas comparison tool to see the current gas market.
Smart Meter Tariffs: What Makes Energia Stand Out
Irish households are increasingly interested in time-of-use pricing following the ESB Networks national smart meter rollout. With a smart meter installed, your electricity can be billed at different rates depending on the time of day — cheaper off-peak and more expensive at peak times (typically early evening on weekdays).
Energia was one of the earlier movers on smart meter tariffs in Ireland. Their Smart Home plan allows customers to:
- Access detailed hourly usage data through the Energia app
- Take advantage of overnight rates for high-consumption appliances
- Understand their own peak versus off-peak usage split
- Charge EVs at significantly reduced overnight rates
For the right household — one that can realistically shift a proportion of usage to off-peak — the Energia Smart Home tariff can save €100–€250 per year compared to a standard flat rate. Our Smart Meter tool can analyse your own ESB Networks interval data to show your actual peak and off-peak split, helping you decide whether time-of-use pricing is worth it for your household.
What Are Energia's New Customer Discounts Like?
Energia offers percentage discounts on their unit rate for new customers who switch online. The introductory discount applies for a fixed period — typically 12 months — before reverting to the standard rate.
The depth of the discount varies and changes periodically. Energia's online-switch process is fully digital: get a quote, enter your MPRN, and they manage the switch from there. No phone calls, no paperwork, and your supply is not interrupted during the transition.
Who Is Energia Best Suited To?
Energia is a strong choice if:
- You have a smart meter (or plan to get one) and can shift usage to off-peak hours
- You drive an EV or plan to, and want an overnight charging tariff
- You want green electricity backed by genuine Irish renewable generation rather than just certificates
- You prefer a fully digital supplier with no-hassle online switching and account management
- Energia happens to have the best standard rate when you compare live tariffs
They are also worth considering if you are an existing customer whose 12-month discount has expired — the online platform makes it very easy to check whether a new deal or a switch elsewhere makes financial sense.
