According to Gas Networks Ireland’s June gas demand report, gas was the largest source of electricity generation during this period, accounting for 43 percent of electricity produced, compared to 36 percent from wind.


In June alone, gas demand dropped by 17 percent month-on-month and 8 percent year-on-year.

Throughout the month, gas remained the primary source of electricity, generating 47 percent, while wind contributed 28 percent.


At times in June, gas powered up to 83 percent of the country’s electricity and never fell below 15 percent.

Gas Networks Ireland’s director of strategy and regulation, Edwina Nyhan, commented on the figures: “While June saw a decrease in gas demand, these latest figures complete a first half of the year marked by strong gas demand overall. Gas’s contribution to electricity generation surpassed that of any other energy source, including wind.

“The figures highlight the evolving role of the gas network in the energy system. As the proportion of renewables increases, the gas network is increasingly vital for providing resilience and security of supply, ensuring that wind energy is supplemented when it isn’t sufficient.


“Our report shows that gas and wind are complementing each other well. Wind’s contribution to the grid peaked at 81 percent in the first half of 2024.

However, due to the variable nature of weather-dependent renewable energy sources, there were also times when wind’s contribution dropped to less than one percent. During these periods, gas served as an essential backup.”
