Bord Gáis Energy and Pinergy have announced price increases for residential electricity customers from next month.
The increase announced by Bord Gáis will see a 13.5% hike on standard unit rates while their standing charges will increase by 12% from 12 October.
This will increase a typical bill for Bord Gáis Energy electricity customers by an average of €18.16 per month, or €218 per year.
Pinergy, meanwhile, confirmed that its price change will result in a 9.83% increase to typical household costs from 13 October, equivalent to €199 annually based on a domestic customer using typical consumption.
There is no change to Pinergy's standing charge.
Bord Gáis Energy said the rise in electricity charges was in response to continued increases in network costs, the impact of wholesale energy markets and the higher cost of doing business. It added that it was its first price hike in three years.
Bord Gáis Energy has 369,000 domestic electricity customers.
Prices for its 270,000 gas customers remain unchanged, the company added.
Director of Customer and Commercial at Bord Gáis Energy Catherine Lonergan said this was the company's first price increase in three years, adding that in that time it had two price reductions across gas and electricity.
"We also absorbed network charges in 2024 saving households an average of €100 in electricity and €75 in gas," she said.
"Due to continued increases in network charges, the higher cost of doing business and the impact of wholesale energy market pricing, we're regrettably announcing a price increase for electricity customers," she said.
"However, I can confirm that there is no change to gas prices for our 270,000 gas customers and that our gas standing charge remains the lowest in the market."
She said that Bord Gáis Energy will continue to compete strongly in the Irish energy market and pass on savings whenever possible.
Pinergy's CEO Enda Gunnell, said it is their "first increase after three price decreases that we made over 2023 and into 2024".
Mr Gunnell said Pinergy absorbed increased network charges approved by the Commission for Regulation of Utilities last year.
"The planned investment in the electricity grid and infrastructure is urgently required but we would call on the exchequer to also play its role in ensuring much needed price stability and minimising the financial burden on consumers," he said.
Earlier this week, Electric Ireland said it would decrease gas prices for 140,000 customers by 4% from the beginning of November, while there will be no increase for the company's 1.1 million electricity customers ahead of the winter.
Energia recently said it would increase its electricity prices by up to 12.1% from 9 October, which will add more than €200 onto the annual bills of many customers.
Last month Flogas hiked its prices by an average of 7%.
Reacting to the latest energy price hikes, the Sinn Féin leader Mary Lou McDonald said: "Here we go again!"
"Another big energy bill hike on the way while Fianna Fáil and Fine Gael prepare to withdraw energy credits from households in the Budget," she said.
"It's a terrible decision. This rip-off must be brought to an end. Workers and families must be supported in the Budget."
