Global private asset manager Capital Dynamics has partnered with Solo Renewables to deliver a potential £100m (€115m) long-duration energy storage system (LDES) in Northern Ireland.
Located in Islandmagee, the 150MW project is designed to provide up to eight hours of storage capacity and, once operational, will be capable of supplying the daily energy needs of up to 36,000 households.
The project received planning approval from Mid and East Antrim Borough Council in February 2026, within six months of the initial submission.
Barney Coles, senior managing director and co-head of clean energy at Capital Dynamics, said: “Long-duration storage has a critical role to play in supporting Northern Ireland’s energy transition and is a fast and efficient way to strengthen grid resilience as renewable generation continues to grow.
“Projects such as this can provide additional flexibility to help manage renewable variability, support grid stability and improve the overall efficiency of the electricity system.”
Andrew Hutchinson, director at Solo Renewables, said: “Securing planning approval in six months reflects the strength of this project and the local understanding that Islandmagee is one of the most strategically important locations in the all-island energy network.
“Northern Ireland has great potential to create and use more renewable electricity locally. This will be a good thing for homes and businesses across the region but can only happen if we increase our ability to store wind and solar energy that can’t be used at the time it’s produced.”
