Solar farms by county
Where is Ireland's utility-scale solar concentrated? Meath, Cork and Wexford lead by both count and capacity, reflecting a combination of grid headroom, flatter topography and proximity to high-irradiance regions in the southeast.

Frequently asked questions about Irish solar farms
How many solar farms are there in Ireland?
Ireland has 168 utility-scale solar farms in the SEAI Solar Atlas — 43 already grid-connected and generating electricity, plus 125 contracted sites at various stages of planning and construction. Combined capacity is approximately 1,781 MW.
What is the largest solar farm in Ireland?
The largest grid-connected solar farm in Ireland is Gallanstown in Meath with a Maximum Export Capacity of 119 MW. Several larger contracted projects are under development, with the biggest pipeline sites exceeding 150 MW.
Where are Ireland's solar farms located?
Most Irish solar farms cluster in the east and south — Meath (17 sites), Cork (29), Wexford (12), Kildare (10), Wicklow (10) and Kilkenny (10) lead the pack. Solar developers favour these counties for grid connection availability, flatter land and higher irradiance in the southeast.
What does MEC mean?
MEC stands for Maximum Export Capacity — the maximum amount of power (in MW) a generator is contractually allowed to export to the electricity grid under its connection agreement with EirGrid or ESB Networks. It's the standard measure used to size utility-scale generators in Ireland.
What's the difference between 'connected' and 'contracted' solar farms?
A connected solar farm is physically built and actively exporting electricity to the grid. A contracted solar farm has secured a grid connection agreement (and in many cases planning permission) but may still be in development, construction, or awaiting energisation. Contracted sites typically take 2–4 years to become connected.
Who owns Ireland's solar farms?
Ownership is fragmented across state, semi-state and private developers. Large players include ESB and Bord na Móna (Timahoe North), Statkraft (Clonfad), Ørsted (Garreenleen, Ballinrea), Neoen (Ballinknockane), EDF Renewables, Octopus Renewables, Power Capital, Highfield Solar and Harmony Solar.
How is this data kept up to date?
Data is fetched directly from the SEAI Solar Atlas, which in turn aggregates records from EirGrid (transmission-connected generators) and ESB Networks (distribution-connected generators). SEAI publishes updates as new connections are energised and new contracts are signed.
