Spain's investigation into the blackout that affected the Iberian Peninsula in late April revealed initial power generation failures in three Spanish provinces — Granada, Badajoz, and Seville, Minister for Ecological Transition Sara Aagesen told the Spanish Congress of Deputies on Wednesday.
The substation in Granada was ground zero, and the power failure caused a loss of 2.2 gigawatts of electricity, causing a chain of grid disconnections. The cause of the substations' failures remains unknown at this time.
