Electric Ireland has set another charge on more than 100,000 householders because they are not using a lot of electricity.
A new 'low user standing charge' came into effect on February 1 targeting customers who use an average of two units or less per day.
According to the Irish Times, their bills will increase by 15.5 cent per day - that is €9.45 in a two-monthly bill.
Householders have been told about the increase in bill inserts in the past fortnight.
