New figures out today show that more than a third - 36% - of the country's power came from wind farms last month.
The country's main renewable energy source met 40% of electricity demand over the first three months of this year, the figures from Wind Energy Ireland show.
Prices on the wholesale electricity market continued their gradual fall, helped by Irish wind farms, for the third consecutive month, it added.
The amount of electricity produced by wind energy last month was up 12% compared to the same time last year, while the share of demand met rose from 33% to 36% as demand for power continued to rise.
Wind Energy Ireland said today that the average wholesale price of electricity fell in March again to €145.25, continuing a gradual drop in prices since the start of the year.
But it noted that the wholesale price of electricity is still more than double the average price before the fossil fuel energy crisis.
Prices fell even further on days with the most wind power when the average cost of a megawatt-hour of electricity was €119.59, rising to €187.29 on days when the energy market had to rely almost entirely on fossil fuels.
Noel Cunniffe, CEO of Wind Energy Ireland, said that Irish wind farms are helping to cut our carbon emissions and to insulate families and businesses from the worst effects of the fossil fuel energy crisis.
"Every time a wind turbine is generating electricity it is reducing our reliance on imported fossil fuels, supporting Irish jobs and helping to push down wholesale electricity prices," Mr Cunniffe said.
"The faster we can build and connect new wind farms, the cleaner and cheaper we make Ireland's electricity supply," he said.
Wind Energy Ireland said the country's planning system remains the main barrier to the rapid development of renewable energy.
"We have fantastic projects queued up in An Bord Pleanála waiting for decisions. We cannot build the wind farms we need to make this country energy independent with a planning system that is simply not up to the job," Mr Cunniffe cautioned.
He said the reforms the Government is bringing forward to the planning system could certainly help but the key issue remains resources.
"There simply are not enough people with the right skills in agencies like An Bord Pleanála, the National Parks & Wildlife Service and the local authorities," he said.
"This year's budget will really be the last chance to provide the funds which are so desperately needed to enable projects to clear the planning system in time to be built for 2030," he added.
