NI Electricity Prices in 2026: What It Means for Solar Panel Owners

Electricity bills in Northern Ireland have climbed again in 2026, with standard tariff rates now sitting between 24p and 28p per kWh depending on your supplier and payment method. For homeowners already paying close attention to their energy costs, these figures are a stark reminder of how much the landscape has changed in just a few years.

Where NI electricity prices stand right now

As of early 2026, the major suppliers in Northern Ireland are charging residential customers roughly 24p to 28p per kWh. SSE Airtricity, Power NI and Budget Energy all sit within this range, though exact rates vary depending on whether you pay by direct debit, prepayment meter or quarterly bill.

Standing charges have also crept up, with most suppliers now charging between 30p and 40p per day just for the privilege of being connected to the grid. For a typical household using around 3,500 kWh per year, that translates to an annual electricity bill of somewhere between £950 and £1,100.

How prices have changed over five years

To put the current rates in perspective, it is worth looking back. In 2021, the average residential electricity rate in Northern Ireland was around 16p to 18p per kWh. That means prices have risen by roughly 50% to 60% in just five years.

The causes are well documented: wholesale gas prices spiked dramatically in 2022, and while they have eased somewhat since, the knock-on effects have kept retail electricity prices elevated. Network charges, green levies and supplier margins have all contributed to keeping bills high even as wholesale costs have partially recovered.

What this means for solar panel savings

Higher electricity prices are, somewhat counterintuitively, good news for solar panel owners. The more expensive grid electricity becomes, the more valuable every unit of solar generation is.

Here is a simple example. A typical 4kW solar panel system in Northern Ireland generates around 3,400 kWh per year. If you use 40% of that electricity directly in your home (which is realistic without a battery), that is 1,360 kWh you do not need to buy from the grid.

At today’s rates of around 26p per kWh, that self-consumed electricity saves you roughly £354 per year. Five years ago, at 17p per kWh, the same self-consumption would have saved you just £231. That is a 53% increase in savings from the same system, purely because electricity has become more expensive.

Add a battery to the mix and self-consumption rates typically rise to 70% or higher, pushing annual savings well above £600 for many households.

Payback periods are getting shorter

The direct consequence of higher electricity prices is shorter payback periods for solar installations. A 4kW system that might have taken 10 to 12 years to pay for itself in 2021 could now pay for itself in 7 to 9 years, depending on your usage patterns and whether you have battery storage.

This calculation also benefits from the fact that solar panel prices have fallen over the same period. The combination of cheaper panels and more expensive electricity has created a sweet spot for homeowners considering the switch.

Export payments add further value

Northern Ireland homeowners with solar panels can also earn money from electricity they export back to the grid. While export rates are lower than what you pay for imports (typically around 5p to 8p per kWh), they still add meaningful value over the lifetime of a system.

For a household exporting 60% of their solar generation (the portion they do not use directly), that could mean an additional £100 to £150 per year in export payments, on top of the savings from reduced bills.

What to expect going forward

Energy analysts do not expect NI electricity prices to fall significantly in the near future. Most forecasts suggest prices will remain in the 22p to 30p range through to 2028, with gradual increases likely as network investment costs are passed on to consumers.

For anyone considering solar panels, this means the financial case is only getting stronger. Every price rise makes your solar generation more valuable, and the long-term trend points firmly in one direction.
