5 days ago, a power supply failure affected the Spanish high speed network. Situation had similarity to the beginning of the blackout this Monday.
5 days ago, the Spanish Energy Company Repsol warned “An unexpected stop due to technical problems with the supply of electricity.”
At issue, according to the advance, was a failure alien to the installation, whose magnitude forced the repsol to activate a “Force majeure” clause.
That same day, April 22, Oscar Puente, the Spanish Minister of Transport, in X that this “excess tension in the power grid” were responsible for incidents that occurred on the railway line High speed from Chamartín to Pajares.
The publication was accompanied by an image that, according to the newspaper, shows the state of the national electrical system at that time, which was very similar to what we observed this Monday.
An excess of the network has caused the protections of the substations to jump from Chamartín to Pajares. The substations have been recovering and now you have to recover the interlocks and signaling. We hope that the circulation is normally normal.

Red Electric, responsible for the distribution of electricity in the country, indicated in the late afternoon of Monday that the cause of the blackout that affected Portugal was a strong imbalance between supply and demand “due to a loss of generation” superior to what is possible to amortize.
According to El Mundo, The entry of renewable energy, mainly solar, is increasing the disadvantage episodes between both variables (Offer and search for energy), which complicates the management of the network by the public company.
However, it is rare to have a discrepancy of this dimension, lying below the electrical system. The causes for electricity failure are yet to be determined, and no confirmation has been given by any responsible entity.
