Imported gas supplied 83% of Ireland’s networked gas in April–June 2026, while indigenous production fell by 9% compared with a year earlier, new Central Statistics Office figures published on Thursday, 22 October show.

The CSO release, issued at 11am, places imports 8% above the same quarter in 2025. Total networked supply increased by 4%. The figures are newly published data about the second quarter, rather than a reading of today’s supply conditions.

Power stations dominate gas demand

Power plants accounted for 68% of networked gas demand during the quarter. Their consumption was about 4% higher year on year; the more precise figure in the CSO’s Table A is 3.6%.

That 68% describes the share of gas demand going to power plants. It is not the share of electricity generated from gas: the release measures gas flows and customer categories, not the full electricity-generation mix.

Non-daily-metered customers — largely households and small businesses — accounted for 13% of gas demand. Their consumption rose by 10.1% compared with April–June 2025. Demand from the separately reported large-daily-metered category fell by 1%, while daily-metered demand increased by 2.1%.

The CSO’s background notes explain that power plants are reported separately from other large users. Keeping those categories distinct avoids counting electricity generators twice when reading the customer breakdown.

June’s increase was sharper than the quarterly change

In June alone, power-plant gas demand was 13% higher than in June 2025, compared with the roughly 4% increase across the full quarter. Total gas demand that month reached 3,706 gigawatt hours, up from 3,451 GWh a year earlier.

The CSO says lower mean wind speeds recorded at Malin Head in June were likely a contributing factor to higher gas use by power plants. That is the agency’s assessment of a possible contribution, rather than a calculation attributing the entire increase to wind conditions.

The longer comparison was more modest: power-plant demand over July 2025–June 2026 rose by 0.8% against the preceding 12 months. A single month, a quarter and a rolling year therefore give different views of the change.

The data come from Gas Networks Ireland administrative records and are subject to revision. They measure physical energy supply and consumption; they do not measure household tariff changes or establish what an individual customer’s winter bill will be.
