Gas Networks Ireland has published its H1 2026 Gas Demand Statement, showing gas generated 38% of Ireland's electricity in the first six months of the year, overall gas demand was 2% higher than H1 2025, and power sector gas demand increased by 13% year on year in June; this is a statistical disclosure, not a transaction, and no deal consideration arises.

Gas Networks Ireland (GNI) is the state-owned operator of Ireland's national gas transmission and distribution network, a wholly owned subsidiary of Ervia. For FY2024, GNI recorded EBITDA of €323 million, post-tax profit of €138 million and operating costs of €276 million, paying a €62 million dividend to Ervia. It employs approximately 629 people and holds an A credit rating from S&P and A2 from Moody's. GNI is developing a €32 million Central Grid Injection facility in Mitchelstown for biomethane and has advanced planning for an FSRU to address supply disruption risk. 

The structural driver is the dunkelflaute problem: the inability of variable renewable energy to guarantee supply during periods of low wind output. Wind generated 35% of Ireland's electricity in H1 2026 but fell to zero at times, while gas covered up to 93% of generation at peak demand moments. That 93% figure, a single-fuel dependency approaching total at certain hours, is the operational argument against aggressive gas phase-out timelines, and the H1 2026 data provides empirical support during a period when Ireland's renewable penetration is at a historic high.

The 13% year-on-year increase in gas demand for power generation in June is the commercially significant number. It indicates that as renewable capacity grows, the call on gas as a balancing fuel is not diminishing. It is increasing, because a larger renewable fleet creates larger swing between surplus and deficit that only dispatchable generation can manage. This is precisely the dynamic underpinning the business case for GNI's biomethane injection infrastructure and the FSRU.

For GNI, the H1 statement is regulatory ammunition as much as operational reporting: data showing power sector demand growth strengthens the case for continued network investment in both the CRU's next tariff review and Ireland's National Energy and Climate Plan implementation.
