Gas Networks Ireland’s latest Gas Demand Statement shows that overall gas demand decreased by 10 per cent month-on-month in April reflecting the seasonal transition into spring.
While overall demand reduced during the month, gas continued to play a critical role in supporting Ireland’s electricity system.
Sectoral gas demand
Most sectors recorded lower gas demand month-on-month in April, with residential demand decreasing by 36 per cent as milder weather1 reduced household heating requirements. The waste management sector was an exception to the broader monthly trend with a 21 per cent increase when compared with March.
Year-on-year a number of sectors also recorded increased gas demand in April, including office complexes (+18 per cent) and hospitals (+17 per cent).
Electricity generation
Gas generated 35 per cent of Ireland’s electricity in April, up from 33 per cent in March. While this was lower than the 41 per cent recorded in April 2025, gas-fired power generation continued to provide critical flexible support for the electricity system during periods when renewable energy output fluctuated. Gas’s contribution to electricity generation never dropped below 16 per cent at any point in the month2.
Wind generation accounted for 38 per cent of electricity generation in April, peaking at 77 per cent at times but also falling away completely during periods of lower wind output. In a sunny month1, solar generation contributed six per cent of electricity generation during the month, up from three per cent in March and four per cent in April last year.
Commenting on the latest figures, Gas Networks Ireland’s Director of Strategy and Regulation, Edwina Nyhan, said:
“While overall demand reduced during April as temperatures became milder, gas continued to provide flexible electricity generation and support key sectors of the Irish economy.
As renewable generation continues to grow, flexible gas-fired generation remains important in maintaining a secure and reliable energy supply for homes, businesses and industry across Ireland.”
