Renewables generated 49% of Ireland’s electricity in March, with new grid-scale solar records, EirGrid said.
The grid operator said wind accounted for 40% of the fuel mix with 1,258GWh generated, while total system demand reached 3142GWh.
EirGrid added that solar output hit a peak of 983.46MW on 21 March, following earlier highs of 979MW and 950MW during the month.
The operator noted that increased rooftop solar reduced daytime demand from conventional generators, with a 974MW drop observed between comparable মার্চ dates.
EirGrid said it is also seeing days where electricity demand is lower in the early afternoon than at night due to embedded solar generation.
“While solar power is currently a relatively small component of the overall fuel mix across a month, these record peaks demonstrate its ever-increasing importance as a source of renewable energy in Ireland as we work towards a more sustainable and renewable ready electricity grid,” said Charlie McGee, system operational manager at EirGrid.
“Looking in particular at the instantaneous power that grid-scale solar can provide, it can meet over 20% of demand at times.
