  According to the website of the Spanish electrical operator Red Eléctrica de España (REE) that documents the power grid, there was sufficient power supplied to the grid leading up to the outage. At 12:30 on 28 April, the grid was supplied with 32 gigawatts (GW) of power to meet 25 GW of demand, and was exporting 2.6 GW to Portugal, 0.87 GW to France and 0.78 GW to Morocco. The remainder was used for hydropumping (3 GW). More than half of the power supply was from solar, and electricity price was slightly negative.
  
  Most of the power drop occurred within five seconds, when a substation in Granada failed, followed by grid failures in Badajoz and Sevilla, and the France connection decoupled at 12:33. There was a sharp drop at around 12:33 on the automatic system that monitors electricity production in Spain, and data after the event are no longer reliable, because communication systems failed as well.
  
  The European Network of Transmission System Operators for Electricity (ENTSO-e) and RTVE (national television) later stated "total zero in the electricity system of the Iberian Peninsula".
  
  As of 9 May 2025, the reason for this outage is still not publicly known. On 9 May 2025, ENTSO-e published a rough timeline of the events leading to the outage, with the cause yet to be determined. ENTSO-e established an expert panel that will investigate the issue, and in the future publish two reports about the event; one about the causes, and one about recommendations.
