Networked Gas Daily Supply and Demand April 2025

Networked Gas Daily Supply and Demand April 2025

Indigenous Gas Production decreased by 15% in April 2025 compared with April 2024

Online ISSN: 2990-8299
CSO statistical release, , 11am

Key Findings

  • In April 2025, Indigenous Gas Production was 15% lower and imports rose 2%, compared with April 2024 (See Tables 1B, 1C, and Figure 1).

  • Imports represented 81% of total gas supply in April 2025, with Indigenous Gas Production from the Corrib gas field and biomethane plants accounting for the remaining 19% (See Tables 1A to 1C).

  • Total gas demand in April 2025 was 4,265 gigawatt hours (GWh), which was 1% lower than the April 2024 figure of 4,326 GWh (See Table 2A).

  • Gas demand in April 2025 by Non-Daily Metered Customers, at 710 GWh, was 24% lower compared with April 2024. This was the lowest Non-Daily Metered gas demand recorded for the month of April since the time series began in 2018 (See Table 2C).

  • In the first four months of 2025, Indigenous Gas Production was down 14% and imports were up 5% compared with the same period in 2024 (See Table A).

Statistician's Comment

The Central Statistics Office (CSO) has today (22 July 2025) published Networked Gas Daily Supply and Demand April 2025.

Commenting on the release, Deirdre Moran, Statistician in the Climate and Energy Division, said: “In the first four months of 2025, total networked gas supply rose 1% compared with the same period in 2024 (See Table A).

During the first four months of 2025, demand by Power Plants was 5% higher, while Non-Daily Metered gas demand, who are largely domestic users and small businesses, was 5% lower compared with the same period in 2024 (See Table A).

April 2025 Trends

Total networked gas supply in April 2025 was 4,340 gigawatt hours (GWh). The April supply figure was 2% lower than the April 2024 figure of 4,419 GWh (See Table 1A). 

In April 2025, Indigenous Gas Production was 15% lower and imports rose 2%, compared with April 2024 (See Tables 1B, 1C, and Figure 1). 

Total gas demand in April 2025 was 4,265 GWh which was 1% lower than the April 2024 figure of 4,326 GWh (See Table 2A). 

In April 2025, gas demand by Power Plants was 6% higher compared with April 2024 (See Table 2B).  

Gas demand in April 2025 by Non-Daily Metered Customers, at 710 GWh, was 24% lower compared with April 2024. This was the lowest Non-Daily Metered gas demand recorded for the month of April since the time series began in 2018 (See Table 2C).  

In April 2025, Power Plants accounted for 65% of total gas demand, while Non-Daily Metered customers represented 17% of total gas demand (See Figure 2 and Tables 2A to 2C).

Weather-Related Data

In April 2025, there were 20 days with a higher maximum daily air temperature recorded at Dublin Airport than in April 2024. This was likely a contributing factor to gas demand by Non-Daily Metered customers being 24% lower in April 2025 compared with April 2024 (See Tables 4C and 5). 

The 08-10 April had the three lowest consecutive days of daily mean wind speed recorded at Dublin Airport for April 2025 which coincided with the three highest days of daily gas demand by Power Plants in April 2025 (See Figure 3, Tables 4B, and 6).”

Indigenous Gas Production was 13.9% lower in the first four months of 2025 compared with the same period in 2024

In the first four months of 2025, Imports were 4.9% higher and Indigenous Production was down 13.9% compared with the same period in 2024. Gas demand by Power Plants was 5.7% higher when comparing the 12-month rolling period of May 2024-April 2025 with May 2023-April 2024 (See Table A).

Daily Gas Supply and Demand Trends April 2018-2025

In April 2025, there were 20 days with a higher maximum daily air temperature recorded at Dublin Airport than in April 2024. This was likely a contributing factor to gas demand by Non-Daily Metered customers being 24% lower in April 2025 compared with April 2024 (See Tables 4C and 5).

Daily Air Temperature and Mean Wind Speed at Dublin Airport April 2018-2025

Lower mean wind speeds typically mean higher gas demand by Power Plants. The 08-10 April had the three lowest consecutive days of daily mean wind speed recorded at Dublin Airport for April 2025 which coincided with the three highest days of daily gas demand by Power Plants in April 2025 (See Figure 3, Tables 4B, and 6).
