Ballynahone Battery Storage is located southwest of Buncrana town on Gransha Road, adjacent to Trillick substation, in Co Donegal.

How it works

Battery energy storage systems enable energy from renewable sources, such as solar and wind, to be stored and then released when the power is needed most.

About us

FuturEnergy Ireland is a joint venture company owned on a 50:50 basis by Coillte and ESB that launched in November 2021. By combining the assets and expertise of these two leading commercial semi-state companies, FuturEnergy Ireland is strongly positioned to tackle climate change and improve energy security on behalf of the people of Ireland.

Our ambition is to develop more than 1GW of renewable energy capacity and a supporting network of energy storage systems by 2030. In doing so, FuturEnergy Ireland will make a significant contribution to Ireland’s commitment to produce 80% of electricity from renewable sources by the end of the decade.


The task of designing and developing a battery storage project can take between three and six months before a planning application is submitted. If this timeline changes, we will keep the community informed through letter-drops and on this website.

Your community engagement manager Shane Lowry will be available throughout to discuss any queries or concerns.
