Return reaches financial close on 55 MW/220 MWh of batteries in Güeñes, Barakaldo and Lezama

Return has reached financial close on a portfolio of three standalone storage systems totalling 55 MW and 220 MWh, under construction in Güeñes, Barakaldo and Lezama (Bizkaia), with commercial operation expected in the second half of 2027. Rabobank is providing €50 million for construction and credit guarantees, CATL supplies the battery technology and Enerland is building the projects. The company frames the aim as reinforcing the grid around Bilbao, an area where grid-scale storage is still scarce.
