| Table A: Networked Gas Supply and Demand Percentage Changes June 2026 | ||
| Category | April-June 2026/2025 | 12-Month Rolling Period July-June 2026/2025 |
| Total Networked Gas Supply | 4.3% | 0.5% |
| Indigenous Production | -9.3% | -14.7% |
| Imports | 7.6% | 4.0% |
| Total Networked Gas Demand | 3.7% | 0.9% |

| Non-Daily Metered | 10.1% | 1.2% |
| Large Daily Metered | -1.0% | 4.0% |
| Daily Metered | 2.1% | -4.8% |
In June 2026, Imports represented 82% of total gas supply with Indigenous Production accounting for the remaining 18%. In comparison, imports in June 2023, represented 74% of total gas supply with Indigenous Production accounting for the remaining 26% (See Figure 1 and Table 1B).
In the second quarter of 2026, demand by Power Plants was 4% higher compared with the same period in 2025 (See Figure 3 and Table A).
Comparing the year 2025 with 2024, networked gas demand was lower for three of the four customer types: Power Plants were 1% lower, Non-Daily Metered customers saw a 5% decrease, Daily Metered customers were down 5%, and Large Daily Metered customers increased by 4%. Overall total gas demand was down 1.5% compared with 2024 (See Tables A and 3B).
June 2026 showed a lower mean wind speed than June 2025. This was likely a contributing factor to gas demand by Power Plants being 13% higher in June 2026 compared with June 2025 (See Figure 6, and Table 4). In Ireland, the Gas Day begins at 05:00 and ends at 05:00 on the following day.

Statistician's Comment
The Central Statistics Office (CSO) has today (22 October 2026) published Networked Gas Daily Supply and Demand April-June 2026.
Commenting on the release, Orla Fallon, Statistician in the Climate and Energy Division, said: “This release contains new data covering the period April to June 2026. In Quarter 2 (Q2) 2026, total networked gas supply was 4% higher compared with the same period in 2025 (See Table A).
In Q2 2026, Indigenous Production was down 9%, and imports were up 8% compared with the same period in 2025 (See Table A).
Comparing April to June of 2026 with the same period in 2025, networked gas demand by customer category showed the following trends: Power Plants (+4%); Large Daily Metered (-1%); Non-Daily Metered (+10%), and Daily Metered (+2%) (See Tables A and 2A).
Power Plants accounted for 68% of total gas demand in Q2 2026, while Non-Daily Metered customers, who are largely domestic users and small businesses, represented 13% of total gas demand (See Table 2A).
