In March 2026, imports represented 85% of total gas supply with Indigenous Production of gas accounting for the remaining 15%. In comparison, imports in March 2023, represented 79% of total gas supply with Indigenous Production of gas accounting for the remaining 21% (See Figure 1 and Table 1B).
In the first quarter of 2026, demand by Power Plants was 2% 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 and customers increased by 4%. Overall total gas demand was down 1.5% compared with 2024 (See Tables A and 3B).
March 2026 showed a higher mean wind speed than March 2025. This was likely a contributing factor to gas demand by Power Plants being 8% lower in March 2026 compared with March 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 (14 August 2026) published Networked Gas Daily Supply and Demand January-March 2026.
Commenting on the release, Orla Fallon, Statistician in the Climate and Energy Division, said: “This release contains new data covering the period January to March (Q1) 2026. In Q1 2026, total networked gas supply was 1% higher compared with the same period in 2025 (See Table A).
Quarterly Comparisons
Indigenous Production of gas was down 16% and imports were up 5% in Q1 2026 compared with the same period in 2025 (See Table A).
Comparing the first quarter of 2026 with the same period in 2025, networked gas demand by customer category showed the following trends: Power Plants (+2%), Large Daily Metered (+2%), Non-Daily Metered (+0.5%), and Daily Metered (-3%) (See Tables A and 2B).
Power Plants accounted for 58% of total gas demand in Q1 2026, while Non-Daily Metered customers, who are largely domestic users and small businesses, represented 27% of total gas demand, over the same period (See Table 2A and Figure 2).
March 2026 Trends
Total networked gas supply in March 2026 was 4% lower than in March 2025 (See Tables 1A and 1B).
In March 2026, Indigenous Production of gas was 17% lower and imports fell 1%, compared with March 2025 (See Tables 1B, and Figure 1).
Total gas demand in March 2026 was 4,671 GWh which was 4% lower than the March 2025 figure of 4,851 GWh (See Table 2B).
In March 2026, gas demand by Power Plants was 8% lower compared with March 2025, and 4% higher when compared with March 2024 (See Table 2B).
In March 2026, Power Plants accounted for 57% of total gas demand, while Non-Daily Metered customers represented 25% of total gas demand (See Figure 2 and Tables 2A and 2B)."
