Gas demand surges as Ireland ends coal in electricity generation

Ireland recorded a sharp rise in gas demand in July as the country marked its first month in more than 40 years without coal contributing to electricity generation.

According to Gas Networks Ireland, overall gas demand in July 2025 rose by 22 per cent compared with June, and by eight per cent compared with July 2024, despite a warmer-than-average month. The increase was largely driven by electricity generation, which rose 35 per cent month-on-month and 12 per cent year-on-year. Demand fell across most other sectors, including residential (-36%), education (-23%) and offices (-21%).

July also marked a historic milestone in Ireland’s energy mix following the closure of Moneypoint’s coal-fired operations in June. Coal no longer contributed to electricity generation for the first time in over four decades.

Gas supplied more than half of the country’s electricity in July, peaking at 92 per cent and never dropping below 17 per cent, helping to maintain stability in the national energy system. Wind provided 24 per cent of electricity, though its contribution fluctuated with periods of low wind.

Con O’Donnell, Head of Regulatory Affairs at Gas Networks Ireland, said: “July’s report shows the vital role gas continues to play in powering Ireland’s energy system, particularly as we transition away from coal. With intermittent renewable energy output, gas is a critical partner, providing the flexibility and reliability needed to ensure a secure energy supply for homes, businesses and communities.”
