The latest news on Spain. Spanish authorities have traced the origin of last month's massive blackout to a sudden power loss at a substation in Granada, followed by near-simultaneous failures in Badajoz and Seville, Spain's energy minister said on Wednesday.
The incidents caused a 2.2 GW drop in generation, disrupting the grid across Spain and Portugal. Ongoing investigations are examining possible voltage issues and prior system volatility, but officials rule out cyberattacks or grid capacity problems.
