What is noteworthy is that this farm had just been built and it was the day of its opening. The fire occurred right at its launch. The equipment was new and untested. Therefore, most likely, the incident occurred as a result of a short circuit.
According to preliminary information, this new cryptocurrency farm was the largest in Europe. The simultaneous launch of all the equipment caused an overload of the networks and overheating of regional transformers. Apparently, this was the cause of the blackout in Spain and Portugal. Although the country's authorities have not named the real culprit of the blackout, in our opinion, this version is very plausible.
Let us recall that on April 28, 2025, there was a massive power outage throughout Spain, part of Portugal and France. What caused it is still unclear and classified at the government level. There were rumors that a rare atmospheric phenomenon or the actions of saboteurs from Russia were to blame.
