Electric Ireland has announced a 10% cut in domestic electricity prices and a 12% reduction in gas charges.
The changes will take place from 1 November and will benefit the utility provider's 1.1 million customers.
The cuts to both unit rate and standing charge will lead to savings of €212.06 a year on the estimated average annual bill for electricity.
The company's gas customers will see an average annual bill fall by €216.67.
It is the first cut in prices by Electric Ireland, which is the largest energy provider in the Irish market, since wholesale energy costs began to soar as a result of the Ukraine war.
Last year, Electric Ireland raised prices three times, the last occasion being October, while in 2021 it raised them twice.
