During the big blackout, one image stood out in particular. While everything else suddenly came to an abrupt halt, some traffic lights continued to function normally. So too did certain businesses and infrastructures. Why did this happen? The answer, of course, lies in their UPS systems.

The 28th of April 2025 will be remembered in Spain and Portugal as the day of the big blackout, when a sudden drop in electricity generation resulted in an almost total power outage in both countries. Businesses, homes and infrastructures stopped working across the board, leaving workers idle, train passengers stranded, and citizens cut off from communication.

In a photovoltaic system with storage, off-grid mode—also known as island mode—enables the battery-powered hybrid inverter to function independently, even when disconnected from the mains, ensuring a reliable power supply during critical situations through genuine energy self-sufficiency.

FC Barcelona has tasked Salicru with supplying all the uninterruptible power supply systems (UPS) for the renovated Spotify Camp Nou. This includes a total of 15 three-phase units, with an aggregate power capacity of 3,600 kW.

Artificial intelligence (AI) has become a significant force in today’s technology landscape, driven by recent advancements and the widespread adoption of tools like ChatGPT, Copilot, and Gemini, and generative AI is increasingly being integrated into various professional, educational, and recreational activities.
