Grid storage is making a comeback: 1.16 GW of battery storage and ano…

Spain's grid operator Red Eléctrica published 50 applications for 2,021.5 MW of grid access: 1,161.5 MW in battery storage (57.5% of capacity) and 845 MW from six large industrial consumers, with Andalusia accounting for over half the total demand. The applications signal unprecedented appetite for grid-connected storage and high-power industrial capacity, though approval depends on technical feasibility and competitive procedures. If you build energy storage or sell to data centres and heavy industry in Spain, you're now competing for grid connection slots in a queue of 50 projects—and Red Eléctrica just signalled where the system has room. The real constraint is no longer capital; it's grid access at specific nodes, and Andalusia is where the competition will be fiercest.
