Pinergy to hike electricity prices by almost 10% from September

The unit rate of Pinergy’s electricity will jump by just under 10%, while its standing charge will remain unchanged.

Electricity supplier Pinergy is set to increase prices from September 14, marking its second price hike in the past 12 months. The rise will affect approximately 28,000 households.

The unit rate of Pinergy’s electricity will jump by just under 10%, while its standing charge will remain unchanged. The costs for the average user are expected to increase by 7.6%, representing a €169 annual increase in bills.

Pinergy said the increase stemmed from higher business costs in the wake of an energy crisis stemming from conflict in the Middle East.

“Year-to-date wholesale costs are now almost 20% higher compared to 2025, and are among the highest in the world,” said Darragh Cassidy, head of communications for the savings website Bonkers.ie.

"On top of this, we've seen fees for the management and upkeep of the electricity grid increase too.

"So the fear was that we'd see more price hikes as we got into autumn. And it's likely most other suppliers will follow suit before the end of the year.” 

Pinergy previously increased its unit rate by almost 13% in October 2025, meaning customers will pay around €370 more for their energy compared to August 2025.

“Unfortunately, the continued volatility in wholesale energy markets has pushed costs to a level that we can no longer absorb,” said Enda Gunnell, chief executive of Pinergy.

“Our hedging strategy has helped protect customers from much of the pricing volatility to date, but the scale and duration of what we're seeing in wholesale markets means a change is now unavoidable.

“We understand this comes at a difficult time for many households, and we would encourage any customer who is concerned about their bill to get in touch with us directly for support,“ Gunnell added.

Energy arrears reach record level 

The hike comes as a record number of households find themselves in energy arrears.

As of May 2025, data from the Commission for Regulation of Utilities (CRU) showed there were 328,273 electricity customers in arrears.

Since May, a number of suppliers, such as Electric Ireland, Yuno Energy and PrepayPower, have hiked prices alongside Pinergy.

Taoiseach Micheál Martin has given no indication of a one-off package to address the issue in October's Budget.

“We have a budget in the first week of October — that will provide us with an opportunity to deal with cost of living pressures on families, some of it occasioned by the fuel but other knock-on consequences in terms of food prices and so on,” Mr Martin told reporters at a doorstep this week in Kanturk, Co Cork.

“Through our taxation measures in the budget, we are going to reduce income tax for workers. We also want in an area like disability to reduce costs and improve the situation and develop the cost of disability agenda to try and alleviate the pressures on families. And also childcare — that is a big cost for many families.

“If you reduce the tax burden, you help with the cost of living, if you reduce the cost of childcare, you help with the cost of living, and if you also work in terms of the cost of disability, you also help families that are particularly under pressure.”
