Electricity Prices in Ireland 2026: What's Going Up, and What It Means for Solar

Irish electricity is getting dearer again in 2026. Electric Ireland — the largest supplier — is raising residential electricity prices by 8% from 1 July 2026, its first increase since October 2022, adding roughly €138 a year to the average electricity bill. PrePayPower moved earlier, lifting unit rates by just under 12% from 1 June. Irish households already pay some of the highest electricity prices in Europe, and every cent on the unit rate makes the electricity you generate yourself worth more. That's the quiet story underneath the headline: when grid power costs more, solar pays back faster.

Electric Ireland's 8% Increase: The Detail

Electric Ireland announced on 28 May 2026 that it would raise residential prices from 1 July. Electricity bills rise by 8% overall, driven by a 9.5% increase in the unit rate — the price you pay per kilowatt-hour — while the standing charge is left unchanged. Gas bills rise by 7.7% over the same period.

For the average household, the company put the electricity impact at €2.66 a week, or €11.52 a month — about €138 over a year. Gas customers face roughly €2.25 a week, or €117 a year, on top.

The increase matters partly because of who Electric Ireland is: it's the country's biggest electricity supplier, so a move on its standard tariff sets the tone for the market. It's also the company's first price rise since October 2022, after a long run of cuts and freezes as wholesale costs eased from their 2022 peak. Electric Ireland pointed to the conflict in the Middle East as the cause, saying it had created "significant upward price pressure on wholesale energy markets."

What Other Suppliers Are Doing in 2026

Electric Ireland isn't alone. PrePayPower raised its electricity unit rates by just under 12% and its gas unit rates by just over 14% from 1 June 2026 — a steeper move, affecting its prepay customer base. Beyond those two confirmed increases, the rest of the market in mid-2026 has been quieter on standard tariffs, with several suppliers competing on new-customer discounts rather than changing their underlying rates.

The pattern is familiar from previous cycles: when wholesale gas prices climb, the largest suppliers move first and the rest follow within a few months. If you're on a fixed-price contract that's coming to an end, it's worth checking what your supplier's standard rate looks like before it rolls over — and worth remembering that none of these rises touch the electricity you make on your own roof.

Not every line on the bill moves with wholesale prices, though. The PSO levy, a fixed regulated charge that funds renewable generation, actually fell for 2025/26 and works the opposite way to unit rates. It's a useful reminder that some bill charges are fixed no matter how much power you use or generate. And if you heat with oil or gas, the carbon tax adds a separate, legislated layer of increases on top of anything suppliers do, on a fixed schedule out to 2030.

Confirmed standard-tariff increases announced as of late June 2026. Other suppliers were competing on new-customer discounts rather than changing standard rates. Always check your own supplier's current rates before assuming.

Why Irish Electricity Stays Among Europe's Dearest

Even after the 2022 wholesale spike unwound, Irish electricity prices never fell back to where they were before the energy crisis. A typical household unit rate in mid-2026 sits at roughly 30–35c per kilowatt-hour including VAT, depending on supplier and plan, and the average annual electricity bill is around €1,800 for a standard urban home. By the standards of the EU, that's near the top of the table.

Several structural factors keep Irish prices high: a heavy reliance on imported gas for power generation, a small island grid with limited interconnection, network and policy costs loaded onto bills, and the standing charges that apply before you use a single unit. None of those are going to reverse quickly. For most homeowners, the working assumption for the rest of the decade is that grid electricity stays expensive — which is exactly the condition under which generating your own makes the most financial sense.

What Rising Prices Do to the Solar Payback Case

The single most important number in any solar payback calculation is the price you pay for imported electricity. The higher that rate, the more each kilowatt-hour your panels produce is worth — because every unit you self-consume is a unit you don't have to buy from the grid at 30–35c.

A 4 kWp system — the most grant-efficient size for most Irish homes — costs roughly €6,200–€9,200 after the €1,800 SEAI grant and currently pays back in about 7–9 years at today's prices. When the unit rate goes up, that payback period shortens, because the annual saving on avoided imports rises with it. An 8% increase doesn't transform the maths overnight, but it moves it in solar's favour — and it does so for the full 20-year-plus life of the system, not just for one year.

Two income streams drive the return. First, the electricity you generate and use directly in the house, which saves you the full import rate of about 30–35c/kWh. Second, the surplus you export under the Clean Export Guarantee, which pays somewhere between 15c and 25c/kWh depending on your supplier. The first €400 of export income each year is tax-free under Revenue's microgeneration exemption (Section 216D, sole or main residence), extended to the end of 2028 by Budget 2026.

See What Solar Would Save on Your Bill

The only way to know what solar does to your bill is to run it against your actual electricity usage. We match homeowners with SEAI-registered installers in your county, who'll size a system to your roof and your consumption, handle the grant and the grid connection, and quote you for free. There's no obligation, and we don't install panels ourselves — so the advice you get isn't a sales pitch.
