Red Eléctrica nears completion of 140 MW/105 MWh of grid batteries in Menorca and Ibiza

Tera Batteries is commissioning the CATL cabinets of the storage systems at the Mercadal substation in Menorca and the San Antonio substation in Ibiza, both promoted by Red Eléctrica. According to pv magazine España the two together come to 140 MW and 105 MWh — 50 MW and 37.5 MWh at Mercadal, 90 MW and 67.5 MWh at San Antonio — making up the largest SATA (storage as a transmission asset) system in the southern EU, with completion expected in early 2027. For Balearic renewable development the context the outlet cites is what matters: the works included expanding the Mercadal and Dragonera substations to ease the connection of new renewable projects and reinforce the Mallorca-Ibiza link.
