Power Grid Map
Ireland Power Grid Map
Substations, transmission lines, power plants and data centres across Ireland on one map, with published substation headroom and the companies behind each asset.
Coverage
What the map holds for Ireland
Figures from the Tera dataset as of 8 October 2026. The map also shows transmission lines, towers, transformers, switches and compensators by voltage level.
Published headroom
Available capacity for generation and demand published for transmission and distribution substations, shown in each substation record.
Data centres
Data centres and other large loads next to the substations that serve them.
Generation and pipeline
Operating wind, solar, gas and storage plants, and projects in development, each linked to its owners and developers.
Market context
How the grid works in Ireland
EirGrid operates Ireland's transmission system, and ESB Networks owns it and runs the distribution network. Ireland and Northern Ireland share a single wholesale electricity market, and wind is the largest source of renewable power.
Data centres already use around a fifth of Irish electricity, and new large connections around Dublin face tight constraints. Published headroom for transmission and distribution substations helps developers of generation, storage and large loads see where capacity remains.
