Wholesale electricity prices fell 35% in June when compared to the same month last year, new figures from Wind Energy Ireland show.
Its latest monthly report shows the average wholesale price of electricity in Ireland per megawatt-hour during the month was €117.11, down from €181.84 in June 2022.
Wind energy provided 20% of the country's energy last month, down on the same month last year.
In the first six months of the year, Irish wind farms provided a third of the island's electricity.
"The first half of the year has been strong for Irish wind farms which have helped to protect Irish families and businesses from the worst effects of relying on expensive imported gas," said Noel Cunniffe, CEO of Wind Energy Ireland.
"New wind farms, along with solar and battery projects, will be connecting before the end of 2023 but we really need to accelerate the delivery of onshore and offshore renewables if we are to reach our legally-binding carbon emissions reduction targets," he added.
Mr Cunniffe said the Government's budget for 2024 will be a chance to provide the funds to resource the planning system to support Ireland's Climate Action Plan objectives for 2030.
"The quicker that projects can clear the planning system, the sooner they can be built and start delivering clean electricity to power our homes, businesses and local communities," he said.
