Keppel is seeking to install battery energy storage at its data centers in Dublin, Ireland.
The company has filed with the Fingal and South Dublin County Councils to install battery energy storage systems (BESS) at its two facilities in the Irish capital.
At its Dublin 1 site in the Citywest Business Campus, the company aims to install an energy storage unit consisting of two new battery storage units, two new HV power skids (PCS transformer and HV RMU), two new MV transformers, concrete slab, and a security fence of 2.4 meters height including two new internal gate entrances.
At its Dublin 2 facility in Ballycoolin Business and Technology Park, Keppel aims to install a 4MW battery energy storage system (BESS) to "improve power quality on site."
Both storage systems are set to be provided by Grid Beyond Limited, which provides grid-connected battery technologies and management software.
Built in 2013, Keppel acquired the Ballycoolin site – previously owned by Dataplex – in 2017. The Citywest site was built in 2000.
Amid an ongoing de facto moratorium on new data centers in Dublin imposed by state-owned grid operator EirGrid due to transmission issues, operators are taking different approaches in the city. Some are seeking to connect data centers to the country's natural gas network, while others are planning to place natural gas power plants on-site or only run off generators.
Microsoft has previously deployed a lithium-ion battery energy storage system (BESS) and a grid-interactive uninterruptible power supply (UPS) at one of its Dublin data centers in partnership with Vertiv and Enel X, saying the project can be rolled out globally.
Echelon Data Centers-linked Data and Power Hub Services was last year granted permission for a 183MW BESS facility on Peamount Road in Newcastle, County Dublin. The site is less than 1km from the Grange Castle Business Park where the likes of Amazon, Microsoft, Google, Digital Realty, Edgeconnex, and CyrusOne operate facilities.
