In the last two months of 2025 demand by Power Plants was 6% lower compared with the same period in 2024 (See Table 2A).
Imports represented 85% of total gas supply in the last two months of 2025, with Indigenous Gas Production accounting for the remaining 15% (See Tables 1A and 1B).
Total gas demand in 2025 was 52,768 gigawatt hours (GWh), which was 1.5% lower than the 2024 figure of 53,563 GWh (See Table A).
Comparing the year 2025 with 2024, networked gas demand differences varied across each of the four customer types: Power Plants (-1%), Non-Daily Metered customers (-5%), Large Daily Metered customers (+4%), and Daily Metered customers (-5%) (See Tables A and 2A).
Power Plants accounted for 64% of total gas demand in 2025, while Non-Daily Metered customers, who are largely domestic users and small businesses, represented 19% of total gas demand (See Tables 2A and 2B).
In 2025, Imports were 1% higher and Indigenous Production was down 16% compared with 2024 (See Table A).
Imports represented 83% of total gas supply in 2025. Annual figures for Indigenous Gas Production have been declining over the last number of years (See Figure 4 and Table 1B).
In 2025, Imports were 1% higher and Indigenous Production was down 16% compared with 2024 (See Table A).

Imports represented 85% of total gas supply in the last two months of 2025, with Indigenous Gas Production accounting for the remaining 15% (See Figure 1 and Table1B).
In the last two months of 2025 demand by Power Plants was 6% lower compared with the same period in 2024 (See Figure 3).
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).

Statistician's Comment
The Central Statistics Office (CSO) has today (29 May 2026) published Networked Gas Daily Supply and Demand November-December 2025.
Commenting on the release, Orla Fallon, Statistician in the Climate and Energy Division, said: “Power Plants accounted for 64% of total gas demand in 2025, while Non-Daily Metered customers, who are largely domestic users and small businesses, represented 19% of total gas demand.
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 Table A).
In 2025 Imports represented 83% of total gas supply. Annual figures for Indigenous Gas Production have been declining over the last number of years (See Figure 4 and Table 1B).
In the last two months of 2025, Indigenous Production was down 15% and imports were down 2% compared with November-December 2024 (See Table 1B).
Comparing November-December 2025 with the same period in 2024, networked gas by customer category showed the following trends: Power Plants (-6%); Large Daily Metered (+8%); Non-Daily Metered (+1%), and Daily Metered (-2.9%) (See Tables 2A and 2B).
Power Plants accounted for 60% of total gas demand in November-December 2025, while Non-Daily Metered customers, who are largely domestic users and small businesses, represented 25% of total gas demand (See Tables 2A to 2B)."
