The portfolio comprises two battery storage projects, which will add 25 MW of storage capacity to the Irish grid network, along with 29 MW of solar PV. The projects were acquired by the NTR Renewable Energy Income Fund II, a wind, solar and energy storage fund that operates across a number of European markets. It said that total costs for the projects amounted to about €29m. Manus O'Donnell, Chief Investment Officer at NTR, said this mix of solar and battery storage brings much-needed diversity of renewables technology onto the Irish grid, particularly for lower wind days.
