We find that battery energy storage can become one of the cornerstones of the energy storage portfolio in Ireland and also one of the few options which can enable the Irish electricity sector to access the required domestic flexibility resources.
We currently have more than 300MWs of battery storage capacity in operation in Ireland, making it one of the largest battery portfolios in Europe. We plan to develop a pipeline of large scale battery projects, as well as additional renewable enabling technologies.
The Kylemore Battery Energy Storage System in Dublin went into operation in 2023 and has the capability of providing 30MW of fast-acting storage. The South Wall Battery Energy Storage System went live in 2023 and has the capability of providing 30MW of fast-acting energy storage.
As renewables like wind and solar increase their share of generation, the need for flexible storage assets grows ever more urgent. The business case for utility-scale batteries in Ireland remains in a formative stage, with evolving policy, market, and grid conditions shaping the sector's trajectory.
While there are technical and geographical constraints for certain technologies, three technologies suitable for implementation in Ireland are battery storage in the short term, pumped storage hydro in

Most home energy storage batteries are lithium-ion (which are also used in consumer electronics). These are lighter, smaller and longer lasting than lead-acid batteries.
At Energy Storage Ireland 2025, the message was clear: energy storage is central to a stable, low-carbon grid, and while short-duration battery systems (BESS) are available, long-duration
Experts from across the energy industry emphasised the importance of energy storage to enhance grid flexibility, support renewable integration, and promote industry decarbonisation.
Considering the policy perspective at the European level, and a comprehensive assessment of the regulatory and electricity market instructions at the national level in Ireland, we recommend...
