New data from the Central Statistics Office (CSO) shows demand for gas hit its lowest levels in June since the organisation started keeping track in 2018 as power plants saw a drop in consumption.

Total gas demand during the month was 7% lower compared to the same month last year. Gas demand by power plants, the largest energy users of networked gas representing 70% of total use in June 2025, saw an 8% reduction in demand year-on-year.

Non-daily metered customers, who are largely domestic users and small businesses, also showed a drop in demand for gas of 14%.

Gas imports were 2% lower in June compared to last year with indigenous production 22% lower. The country’s main gas field at Corrib had planned maintenance scheduled during the month.

The fall in demand for gas comes as renewable energy met almost 38% of Ireland’s demand in June, according to electricity grid operator EirGrid, with the month setting a new record for solar production.

Some 30% of total electricity needs were met by wind power during the month, with a further 5% coming from solar over the month, and 2.5% coming from other renewables.

Just over 1% of demand was met by coal, with June marking the last month in which it will be used for electricity generation following the final use of coal power at Moneypoint.

Overall, during the first six months of the year, indigenous gas production is down 15% compared to the same period in 2024, while imports are up 1%.

Senior statistician with the CSO Orla McCarthy said that during the first six months of 2025, gas demand by non-daily metered customers was 7% lower compared with the same period in 2024, whereas gas demand by power plants was 1% lower.
