Granada substation power loss pinpointed as origin of massive blackout in Spain, Portugal
- On April 28, an abrupt power loss of 2.2 gigawatts occurred at a Granada substation, triggering grid failures in Badajoz and Seville and causing a massive blackout across Spain and Portugal.
- Investigations attribute the incident to generation losses outside the main grid, possibly at power plants or smaller grids, with causes like excessive voltage under review and cyberattacks ruled out.
- The blackout disrupted essential services, stranded trains, and impacted tens of millions of people, while Spain’s reliance on renewables and phasing out nuclear energy have drawn scrutiny amid complex grid challenges.
- Spain's Energy Minister Sara Aagesen stated that millions of data points are being analysed, that the event is extremely complex, and that there was no prior warning or alert before the blackout.
- The government pledged to work transparently and rigorously on findings, with parallel investigations ongoing that may impose fines up to 60 million euros depending on outcomes and highlight the need to adapt the grid.
