Total gas demand in June 2025 was 7% lower compared with June 2024. This was the lowest total gas demand recorded for the month of June since the time series began in 2018 (See Table 2B).
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 when compared with June 2024 (See Table 2B).
Gas demand by Non-Daily Metered customers, who are largely domestic users and small businesses, also showed a reduction in gas consumption in June 2025, down 14% compared with June 2024 (See Table 2B).
Imports were 2% lower in June 2025 compared with June 2024. Indigenous Production was 22% lower in June 2025 compared with June 2024 (See Table 1B). The Corrib gas field had planned maintenance scheduled for June 2025.
In the first six months of 2025, Indigenous Gas Production was down 15% and Imports were up 1% compared with the same period in 2024 (See Table A).
We have changed the format of the monthly Networked Gas Daily Supply and Demand release, if you would like to provide feedback please use the feedback box to the right. We have also added monthly and annual PxStat Tables. See Data page for the full list of PxStat tables related to this release.
Note that in Ireland, the Gas Day begins at 5 am. Gas customer types are categorised based on their annual consumption. Power Plants are a subset of Large Daily Metered but for the purposes of this release we report Power Plants demand separately. In this release Large Daily Metered excludes Power Plants. See the Background Notes for the full definition of gas customer types.
In the first six months of 2025, Imports were 0.8% higher and Indigenous Production was down 15.3% compared with the same period in 2024. Gas demand by Power Plants was 5.2% higher when comparing the 12-month rolling period of July 2024-June 2025 with July 2023-June 2024 (See Table A).
| Table A: Networked Gas Supply and Demand Percentage Change June 2025 | ||
| Category | Year-to-Date January-June 2025/2024 | 12-Month Rolling Period July-June 2025/2024 |
| Total Networked Gas Supply | -2.5% | 3.0% |
| Indigenous Gas Production | -15.3% | -6.9% |
| Gas Imports | 0.8% | 5.6% |
| Total Networked Gas Demand | -2.3% | 2.9% |
| Power Plants | -0.9% | 5.2% |
| Non-Daily Metered | -7.4% | -3.2% |
| Large Daily Metered | -0.1% | 0.5% |
| Daily Metered | -1.4% | 3.5% |
In June 2025, Imports represented 83% of total gas supply with Indigenous Production accounting for the remaining 17%. In comparison, Imports in June 2018, represented 35% of total gas supply with Indigenous Production accounting for the remaining 65% (See Figure 1 and Table 1B).
In June 2025, gas demand by Power Plants was 8% lower compared with June 2024. The three lowest consecutive days of daily gas demand by Power Plants in June 2025 occurred across 01-03 June. On days where there is more wind available, a smaller proportion of electricity is generated by power plants (See Figure 3 and Table 2B).
Comparing the year 2024 with 2023, networked gas demand was higher for each of the four customer types: Non-Daily Metered customers (+5%), Daily Metered customers (+5%), Large Daily Metered customers (+0.5%), and Power Plants (+2%) (See Table 3B).
We have introduced a new format for this release. Any feedback from readers of this release is welcome.

Statistician's Comment
The Central Statistics Office (CSO) has today (19 September 2025) published Networked Gas Daily Supply and Demand June 2025.
Commenting on the release, Orla McCarthy, Senior Statistician in the Climate and Energy Division, said: “Total gas demand in June 2025 was 7% lower compared with June 2024. This was the lowest total gas demand recorded for the month of June since the time series began in 2018 (See Table 2B).
Power Plants, which are the largest consumers of networked gas, showed an 8% reduction in consumption in June 2025 compared with June 2024 (See Table 2A).
Gas demand by Non-Daily Metered customers, who are largely domestic users and small businesses, also showed a reduction in gas consumption in June 2025, which was down 14% compared with June 2024 (See Table 2B).
In June 2025, Power Plants accounted for 70% of total gas demand, while Large Daily Metered customers represented 14% of total gas demand (See Table 2A).
Imports were 2% lower in June 2025 compared with June 2024. Indigenous Production was 22% lower in June 2025 compared with June 2024 (See Table 1B). The Corrib gas field had planned maintenance scheduled for June 2025.
In the first six months of 2025, Indigenous Gas Production was down 15% and Imports were up 1% compared with the same period in 2024 (See Table A).
During the first six months of 2025, gas demand by Non-Daily Metered customers, who are largely domestic users and small businesses, was 7% lower compared with the same period in 2024, whereas gas demand by Power Plants was 1% lower compared with the same period in 2024 (See Table A).”
