Gas generated 45% of Ireland's electricity in August while wind energy supplied 27%

August 2025 was fourth warmest ever recorded

Gas demand last month fell 9% compared to July, as warmer weather reduced heating needs across the country and stronger wind generation was recorded.

August 2025 was the fourth warmest on record, and month-on-month gas demand fell. Nevertheless, Gas Networks Ireland’s latest Gas Demand Statement shows that overall gas demand in August 2025 was 9% higher than in August 2024, driven in part by increased use in electricity generation, as coal-powered generation has been phased out over the past 12 months.
