Gas Demand Surges as Ireland Phases Out Coal

Ireland saw a sharp rise in gas demand in July 2025 as the country recorded its first month in more than four decades without coal contributing to electricity generation.

According to Gas Networks Ireland, overall gas demand in July increased by 22 per cent compared to June and by eight per cent year-on-year, despite warmer than average temperatures. The rise was largely driven by higher demand for electricity generation, which grew by 35 per cent compared to June and by 12 per cent compared to July 2024.

Demand fell in other sectors, including residential (-36%), education (-23%) and offices (-21%) month-on-month.

July marked a historic milestone in Ireland’s energy mix following the closure of Moneypoint’s coal-fired operations in June 2025. Gas supplied over half of the country’s electricity during the month, peaking at 92 per cent and never falling below 17 per cent. Wind energy provided 24 per cent of electricity, though output dropped to zero during 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 the country transitions away from coal. With intermittent renewable energy output, gas provides the flexibility and reliability needed to ensure a secure supply for homes, businesses and communities.”
