Battery storage + Solar at Thomastown
on lands within the townlands of Castlegarden and Cloghscregg , Thomastown , County Kilkenny
This project holds a grid connection offer
EirGrid's connection batches record an offer for this application with a maximum export capacity of 140.0 MW, connecting at the Kilkenny node. EirGrid lists it as Castlegarden Solar Farm and Battery, applicant Lightsource Renewable Energy Ireland Limited. The offer quarter is Q2 2026.
Source: ECP-GSS-1 Final Batch, May 2026. Matched to this application by the planning reference EirGrid publishes, confirmed against the county. An offer is a place in the connection process, not a connection: it does not mean the project is built or generating.
Grid
Association: No confident match to a named grid station.
Available capacity: 1.7 MW of firm generation capacity available at GRAIGUENAMANAGH.
A nearest substation is a measurement of distance, not a statement of where this project will connect. Where a link is published it is because the application names the station, or because the project's own place name matches it and the two are close enough for that to mean something.

Own land near one of these?
We track every solar, wind and battery application in the national planning register — and the large ones made directly to An Coimisiun Pleanala, which never reach a council register at all — as they move through planning, and which substations still have capacity to take a connection. If you want to be told when something is lodged near your land, leave an email address.
Email us to be added to the list — we will only use it to send project alerts for the areas you name.
No lease rates or valuations are published here, and nothing on this site is an offer or a recommendation.
