Household energy bills could rise by around €700 per family after a price hike was announced by Bord Gais.
They're ending their 'winter price pledge' from April 15th and raising gas tariffs by 39% and electricity prices by 27%.
It's expected other energy suppliers will follow suit.
Minister Paschal Donohue says while people will soon feel the effects of the energy rebate and the reduction in excise on fuel, the Government can't meet all of the costs.
"We've brought in additional payments as well such as the €175 , which has been made available to those families and to pensioners who will be particularly affected by these changes, but I do want to couch it all by acknowledging, that even with the changes that we have made or other measures that the government has to put in place to deal with other challenges that we are facing at the moment, we can't cover all of the costs"
