Electric Ireland has said that due to recent costs hitting the broader electricity system and market it will increase its average residential electricity bill by 3.4% from October 1.
It said this will equate to an increase of €2.88 a month on the average residential electricity bill.
But Electric Ireland said it is freezing gas prices this winter to help residential gas customers during the higher usage months.
In April, Electric Ireland had reduced energy bills for both its gas and electricity customers by about €100 a year because fuel costs were falling at that time.
But it said today that unfortunately, due to other electricity system and market costs outside of its control, it now has to increase its electricity prices in October.
Electric Ireland also said it continues to offer a 5% discount to customers experiencing financial hardship through industry pre-payment meters and through the Household Budget Scheme.
