ESB to add 105 MW of batteries in Dublin with Fluence

Energy storage company Fluence last week revealed a deal with Irish state-owned utility ESB for energy storage projects totalling 105 MW/210 MWh at two ESB plants in Dublin.

A 75-MW/150-MWh battery will be added to ESB’s plant in Poolbeg, and a 30-MW/60-MWh battery will be deployed at an ESB site at South Wall. The two two-hour duration energy storage systems are due to be completed in early 2023. They are in addition to two projects that Fluence is already carrying out for ESB at Inchicore, Dublin, and Aghada, Co Cork, of 38 MWh and 60 MWh, respectively.

The energy storage company, which is a joint venture between Siemens AG (ETR:SIE) and AES Corp (NYSE:AES), and last week filed for an initial public offering (IPO), said the total 308 MWh of projects constitute the largest energy storage portfolio deal in Europe, while the 75-MW/150-MWh battery in Poolbeg is the largest by energy capacity signed in the EU.

The 308-MWh battery fleet is expected to be capable of powering some 321,000 Irish homes and businesses during peak demand.

According to Paul McCusker, president for Fluence Europe, Middle East and Africa Paul, the systems will swiftly provide much needed flexible capacity for the constrained Dublin area.

Paul Smith, head of asset development at ESB Generation Trading, this first ESB battery portfolio of scale demonstrates the company’s commitment to developing renewables-enabling projects in line with its Brighter Future Strategy.
