Total gas demand in October 2025 was 3% lower compared with October 2024 (See Table 2B).
Gas demand by Power Plants, the largest energy users of networked gas representing 64% of total use in October 2025, saw a 6% decrease in demand when compared with October 2024 (See Table 2B).
Gas demand by Non-Daily Metered customers, who are largely domestic users and small businesses, showed an increase in gas consumption in October 2025, up 4% compared with October 2024 (See Table 2B).
Imports were 1% lower in October 2025 compared with October 2024 while Indigenous Production was 16% lower (See Table 1B).
In the first 10 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 added monthly and annual PxStat Tables to the Networked Gas Daily Supply and Demand release. See Data page for the full list of PxStat tables.
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 10 months of 2025, Imports were 2.3% higher and Indigenous Production was down 16.1% compared with the same period in 2024. Gas demand by Power Plants was 4.6% higher when comparing the 12-month rolling period of November 2024-October 2025 with November 2023-October 2024 (See Table A).

| Category | Year-to-Date January-October 2025/2024 | 12-Month Rolling Period November-October 2025/2024 |
| Total Networked Gas Supply | -1.6% | 1.5% |
| Indigenous Gas Production | -16.1% | -15.6% |
| Gas Imports | 2.3% | 6.1% |
| Total Networked Gas Demand | -1.1% | 1.9% |
| Power Plants | 0.2% | 4.6% |
| Non-Daily Metered | -6.5% | -5.3% |
| Large Daily Metered | 3.0% | 3.7% |
| Daily Metered | -5.6% | -4.4% |
In October 2025, Imports represented 83% of total gas supply with Indigenous Production accounting for the remaining 17%. In comparison, Imports in October 2018, represented 43% of total gas supply with Indigenous Production accounting for the remaining 57% (See Figure 1 and Table 1B).
In October 2025, gas demand by Power Plants was 6% lower compared with October 2024. The lowest consecutive days of daily gas demand by Power Plants in October 2025 occurred across 25–26 October. 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).

Statistician's Comment
The Central Statistics Office (CSO) has today (14 April 2026) published Networked Gas Daily Supply and Demand October 2025.
Commenting on the release, Orla Fallon, Statistician in the Climate and Energy Division, said: “Total gas demand in October 2025 was 3% lower compared with October 2024 (See Table 2B).
Power Plants, which are the largest consumers of networked gas, were responsible for almost two-thirds (64%) of total gas demand in October 2025. They showed a 6% decrease in consumption in October 2025 compared with October 2024 (See Table 2B).
The second largest user group is Non-Daily Metered customers, who are mainly domestic users and small businesses. They showed an increase in gas consumption in October 2025, up 4% compared with October 2024 (See Table 2A).
Imports were 1% lower in October 2025 compared with October 2024. Indigenous Production was 16% lower in October 2025 compared with October 2024 (See Table 1B).
During the first 10 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 slightly higher (+0.2%) compared with the same period in 2024 (See Table A).
