Gas Networks Ireland's latest Gas Demand Statement reveals that overall gas demand decreased by 10 per cent month-on-month in April, reflecting the seasonal transition into spring.

While overall demand fell during the month, gas maintained its critical role in supporting Ireland's electricity system.

Most sectors recorded lower month-on-month gas demand in April. Residential demand dropped by 36 per cent as milder weather reduced household heating requirements. Conversely, the waste management sector bucked the broader monthly trend, experiencing a 21 per cent increase compared to March.

On a year-on-year basis, several sectors registered higher gas demand this April, including office complexes (+18 per cent) and hospitals (+17 per cent).

Gas generated 35 per cent of Ireland's electricity in April, up from 33 per cent in March. Although this was lower than the 41 per cent recorded in April 2025, gas-fired power generation continued to provide critical, flexible support to the electricity grid during periods when renewable energy output fluctuated. The contribution of gas to electricity generation never dropped below 16 per cent at any point in the month.

Wind generation accounted for 38 per cent of total electricity generation in April, peaking at 77 per cent but also falling away completely during periods of lower wind output. Driven by a sunny month, solar generation contributed six per cent of the electricity mix, up from three per cent in March and four per cent in April last year.

Commenting on the 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."
