Catalonia, despite some improvement, has been at the back of the queue for renewable energy development in the state. But now the Generalitat (Catalan government) has approved regulations that could be key to promoting green energy and, at the same time, could become a factor in ensuring system security and avoiding massive blackouts like the one that occurred on the Iberian Peninsula on April 28. A government decree declares the batteries as facilities of superior public interest..

The executive council of the Generalitat has approved a decree law that declares of superior public interest theelectrical storage with batteriesIt is the first Spanish administration to take this step, which is key to streamlining the processing of these facilities and providing security and stability to renewable energy. The decree-law seeks, on the one hand, to regulate and incentivize batteries and, on the other, to accelerate the energy transition and streamline the processing of solar, wind, and storage farm projects under the jurisdiction of the Generalitat (Catalan Government).

In May 2022, Seoul announced the most significant industrial investment in Catalonia in the last twenty years: a battery component factory in Mont-roig del Camp. With €600 million and 500 direct jobs, the Korean company ILJIN (now LOTTE) intended to establish its first plant in Europe.

China produces 80% of all batteries in the world, with far more supply than demand, complicating Europe's efforts to have its own industry. In a context in which promising new technologies are emerging, China's dominance of the market is becoming increasingly evident.
