ESB to develop new battery units for power storage

The move is in addition to similar projects already announced for Cork and Dublin.

The announcement comes as concerns continue over the resilience of Ireland's energy supply systems.

ESB and energy storage company Fluence is to develop new battery storage units at two plants in Dublin. 

These are in addition to similar developments already under way in Dublin and Cork. When all are completed, the units will have the capacity to power approximately 321,000 homes and businesses in Ireland at times of peak demand.
