Battery storage at Lahardan
Townlands of Glenhouse and Lahardan Co. Waterford , on a site approximately 15 kilometres , West of Waterford City.
This project holds a grid connection offer
EirGrid's connection batches record an offer for this application with a maximum export capacity of 133.0 MW, connecting at the Cullenagh node. EirGrid lists it as Lahardan BESS Solar, applicant Cullenagh BESS Limited. The offer quarter is Q3 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: Nothing states a connection point and the place name does not match a station, but CULLENAGH is only 1.01 km away — close enough that it is usually, though not always, where a project like this connects. Counted separately from the match rate.
Available capacity: ESB Networks has not published available generation capacity for CULLENAGH.
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.
