Energy Minister Eamon Ryan has defended plans for a multi-million euro rebrand of Bord Gáis and the ESB as ordered by the regulator.
It was reported that the cost for the rebrand of Bord Gáis could be as much as €40m, while the cost for the ESB could be €6.8m.
The news comes at a time when thousands of people are being disconnected for being unable to pay their bills.
Minister Ryan said that consumers won't pay for the rebranding costs, and will stand to benefit from the developments in the long run.
He said: "The regulator said it (rebranding) would not be put on the price of consumers.
Mr Ryan insisted that the "benefits we get in competition are a multiple of any such cost effect."
