The wholesale price of electricity last month was 155% higher than in the same month last year as a result of the rising cost of energy on international markets and Ireland's reliance on fossil fuels.
However, at €218.26 per megawatt hour, the price was lower than the record high of €293.25 in March.
Wind Energy Ireland said the price in April could have been higher had it not been for the increased contribution of wind.
Last month was the strongest April on record for wind generation here, with around 32% of our electricity generated by this means.
That represents a 7% increase on the same month in 2021.
It follows a strong first quarter of the year for the renewable, during which wind contributed 39% of Ireland’s generating capacity.
However, the fluctuating nature of wind speed means that level of output isn't constant.
Last year lower wind speeds and lower rainfall amounts saw the percentage of electricity generated by renewables fall from 42% in 2020 to 35%.
Wind energy fell by 15.8% while hydro-electric generation fell 19.6% according to the Sustainable Energy Authority of Ireland.
"Every new wind farm and solar farm connecting to the electricity system helps to make Ireland more energy independent," said Noel Cunniffe, CEO of Wind Energy Ireland.
"We need to accelerate the development of clean, cheap, renewable energy to push fossil fuels out of the electricity market," he said.
Ireland is currently in a push to increase its levels of renewable generating capacity, particularly through the provision of more offshore wind turbines.
A large number of projects are planned for development over the coming decade, especially along the east coast.
However, the speed of delivery has come under sharp focus since the outbreak of war in Ukraine which has driven the cost of energy internationally significantly higher.
"Our planning system must be reformed and properly resourced to ensure that the renewable energy projects needed by the Climate Action Plan can get properly, but quickly, examined and we can move forward with getting those projects built," Noel Cunniffe said.
