About this market
Grid operator
EirGrid in Ireland and SONI in Northern Ireland.
Bidding zone
Ireland and Northern Ireland trade as one all-island Single Electricity Market (SEM).
Generation in 2025
Largest sources: gas 48.4%, wind 38.0%, solar 4.8% (Republic of Ireland only).
Data-centre rule
The regulator’s 12 December 2025 decision (CRU/2025/236) requires new data centres to bring on-site or local generation or storage matching their import capacity, and to meet at least 80% of annual demand with additional renewable generation in Ireland.

Notes
- Carbon intensity is estimated from each market’s generation by fuel. Forward hours follow the renewables forecast.
- Prices are day-ahead wholesale, not what a site pays.
- Ireland shows carbon only, with no forward hours.
- “Delayed” marks a series that missed its last refresh.
