What Energia costs at different usage levels
The same plan (Smart Data) priced at the three usage presets used across this site. A low user is hit harder by the standing charge, a heavy user by the unit rate — which is why one supplier can be cheapest for a flat and dearest for a family home.
| Household | Annual usage | First year | Ongoing |
|---|---|---|---|
| Low use | 2,900 kWh | €1,073.37 | €1,365.29 |
| Medium use | 4,200 kWh | €1,427.18 | €1,849.96 |
| High use | 5,800 kWh | €1,862.63 | €2,446.47 |
About Energia
Energia is part of Energia Group, an all-island energy business that both generates and supplies. It owns and operates wind farms in Ireland and Northern Ireland and sells electricity and natural gas to homes and businesses in the Republic. Unlike the two incumbents it has no legacy customer base, so it has grown almost entirely by winning switchers, and its pricing tends to reflect that.
Its electricity range is built around the smart meter. If you have had a smart meter installed by ESB Networks, Energia gives you the widest choice we see: a flat smart tariff, a day/night split, and a plan aimed at households that actively shift consumption. If you are still on a legacy 24-hour meter, its range narrows to a single standard plan and the case for Energia rests on the discount alone.
Two things to check before switching. First, a smart tariff only pays if your usage profile actually matches it — the default assumption used across this site is 63% day, 28% night and 9% peak, and if most of your electricity goes in at teatime a smart plan can cost you more than a flat one. Second, as with every supplier here, Energia’s discount applies for the first 12 months.
Switching to or from Energia is free, takes about two to three weeks, and needs your MPRN or GPRN, a recent meter reading and bank details for direct debit.
Energia leans harder into smart tariffs than most suppliers we track — its Smart 24 Hour, Smart Day/Night and Smart Data plans all assume a smart meter, and only one plan in its range is aimed at a plain 24-hour meter.

Those figures include the standing charge and the PSO levy but assume the usage split shown on this page. Use the table above to see what a low or heavy user would pay.
What meter types does Energia support?
The Energia plans in our data cover smart tariff, standard 24-hour meters. Your meter type is fixed by the hardware on your wall, not by the supplier, so check which one you have before comparing — a smart tariff on a household that cannot shift usage to the night band will usually cost more than a flat rate. See smart meter tariffs for how the bands work.
How do I switch to Energia?
Switching is free and takes about two to three weeks, with no interruption to your supply. You need your MPRN, which is printed on any recent electricity bill, a current meter reading, and bank details — direct debit is required on the discounted plans. Set a reminder for month 11: the first-year discount ends at month 12 and the account rolls onto the standard rate. Our switching guides walk through the whole process.
