What EirGrid does
EirGrid plc is Ireland's designated Transmission System Operator (TSO), a state-owned commercial enterprise established in 2000 under the European Communities (Internal Market in Electricity) Regulations 2000 and licensed under the Electricity Act 1999. The company develops, manages, and operates Ireland's high-voltage electricity grid, balancing supply and demand in real time from National Control Centres in Dublin and Belfast (the latter operated through its wholly-owned subsidiary SONI for Northern Ireland). EirGrid's core mandate is ensuring secure, reliable electricity supply while leading the transition to 80% renewable electricity by 2030, currently integrating up to 75% of system demand from variable renewables at any moment (targeting 95%) and enabling cross-border trade through interconnectors to Great Britain (East-West, Greenlink) and France (Celtic Interconnector, 700 MW).

Revenue model
- Transmission System Operator Services: EirGrid operates as a regulated monopoly under a TSO licence. Revenue is derived from regulated network tariffs approved by CRU (Commission for Regulation of Utilities), which recover the costs of operating, maintaining, and developing the transmission system from electricity consumers
- Capacity Market Revenue: EirGrid procures generation capacity through capacity auctions to ensure security of supply, with generators receiving capacity payments
- Interconnection Revenue: Revenue from operating interconnectors including East-West Interconnector and Greenlink Interconnector connecting Ireland to Great Britain

Products and services
- Transmission System Operator Services Regulated operation, maintenance, and development of Ireland's high-voltage electricity transmission grid 24/7, including real-time balancing of supply and demand from the National Control Centre. Provided to generators, distribution system operators, and large energy users under a TSO licence with CRU-approved cost recovery.
- Capacity Market Procurement Competitive capacity auctions procuring generation capacity to ensure security of supply, with generators receiving capacity payments via multi-year contracts. Includes the 10-year capacity contract structure used for new technologies such as long-duration storage.
- Cross-Border Interconnector Services Operation of high-voltage interconnectors linking Ireland to Great Britain and continental Europe, including the East-West Interconnector and Greenlink Interconnector (UK), and the 700 MW Celtic Interconnector (France) being co-developed with RTE. Provides wholesale cross-border electricity trading and security of supply.
- Single Electricity Market (SEM) Operation Operation of the all-island wholesale electricity market through SEMO (jointly with SONI), including Day-Ahead, Intraday, and Balancing Markets. Now supports direct battery storage participation under the Scheduling and Dispatch Programme.
- Scheduling and Dispatch Programme (SDP) New wholesale market mechanism enabling battery storage units to participate directly in the Day-Ahead, Intraday, and Balancing Markets of the Irish SEM. Replaces prior dispatch arrangements to support Ireland's low-carbon transition.
- DS3 System Services System services programme that enables up to 75% of electricity to be generated from variable renewable sources (wind and solar) at any one time, with work ongoing to increase this to 95%. Provides ancillary services payments to providers of system stability, inertia, and reactive power.
- Low Carbon Inertia Services Procurement of synchronous condensers and long-duration electricity storage to deliver grid inertia and stability services as fossil-sourced inertia declines. Targets 500 MW of long-duration electricity storage capacity by 2030.
- Grid Connection Services Regulated transmission grid connection services for generators (wind, solar, hydro, battery, conventional) and large energy users (data centres, industrial customers) under CRU-governed connection agreements, including capacity allocation and dispatchable generation requirements for new data centres.
