Total gas demand in July 2025 was 8% higher compared with July 2024 (See Table 2B).
Gas demand by Power Plants, the largest energy users of networked gas representing 77% of total use in July 2025, saw a 12% increase in demand when compared with July 2024 (See Table 2B).
Gas demand by Non-Daily Metered customers, who are largely domestic users and small businesses, showed a reduction in gas consumption in July 2025, down 16% compared with July 2024 (See Table 2B).
Imports were 13% higher in July 2025 compared with July 2024. Indigenous Production was 18% lower in July 2025 compared with July 2024 (See Table 1B).
In the first seven months of 2025, Indigenous Gas Production was down 16% and Imports were up 2% 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 5am. 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 seven months of 2025, Imports were 2.3% higher and Indigenous Production was down 15.8% compared with the same period in 2024. Gas demand by Power Plants was 5.9% higher when comparing the 12-month rolling period of August 2024-July 2025 with August 2023-July 2024 (See Table A).
| Table A: Networked Gas Supply and Demand Percentage Change July 2025 | ||
| Category | Year-to-Date January-July 2025/2024 | 12-Month Rolling Period August-July 2025/2024 |
| Total Networked Gas Supply | -1.5% | 3.0% |
| Indigenous Gas Production | -15.8% | -12.0% |
| Gas Imports | 2.3% | 7.1% |
| Total Networked Gas Demand | -1.0% | 3.3% |
| Power Plants | 1.1% | 5.9% |
| Non-Daily Metered | -7.8% | -3.8% |
| Large Daily Metered | 1.2% | 1.5% |
| Daily Metered | -2.6% | 1.9% |
In July 2025, Imports represented 81% of total gas supply with Indigenous Production accounting for the remaining 19%. In comparison, Imports in July 2018, represented 37% of total gas supply with Indigenous Production accounting for the remaining 63% (See Figure 1 and Table 1B).
In July 2025, gas demand by Power Plants was 12% higher compared with July 2024. The four lowest consecutive days of daily gas demand by Power Plants in July 2025 occurred across 03-06 July. 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 (31 October 2025) published Networked Gas Daily Supply and Demand July 2025.
Commenting on the release, Dympna Corry, Statistician in the Climate and Energy Division, said: “Total gas demand in July 2025 was 8% higher compared with July 2024 (See Table 2B).
Power Plants, which are the largest consumers of networked gas, showed a 12% increase in consumption in July 2025 compared with July 2024 (See Table 2B).
Gas demand by Non-Daily Metered customers, who are largely domestic users and small businesses, showed a reduction in gas consumption in July 2025, which was down 16% compared with July 2024 (See Table 2A).
In July 2025, Power Plants accounted for 77% of total gas demand, while Large Daily Metered customers represented 12% of total gas demand (See Table 2A).
Imports were 13% higher in July 2025 compared with July 2024. Indigenous Production was 18% lower in July 2025 compared with July 2024 (See Table 1B).
In the first seven months of 2025, Indigenous Gas Production was down 16% and Imports were up 2% compared with the same period in 2024 (See Table A).
During the first seven months of 2025, gas demand by Non-Daily Metered customers, who are largely domestic users and small businesses, was 8% lower compared with the same period in 2024, whereas gas demand by Power Plants was 1% higher compared with the same period in 2024 (See Table A).”
