Battery Storage

Our Battery Storage Ambitions

We are at the forefront of developing battery systems, supporting the decarbonisation of Ireland's electricity system. 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. This is crucial to supporting the balancing of the grid and will facilitate even more onshore wind, offshore wind and solar onto the electricity system in the coming decades.

ESB has shown its commitment to battery storage technology through active investment. We have over 300MWs of two-hour storage across five sites, enough to power around 200,000 homes. That represents an investment of €300million.
