One year after Spain’s blackout, its shift to renewables and grid evolution power on

One year ago, Spain and much of Portugal experienced an unprecedented blackout due to a cascading failure in the grid, resulting in Europe’s first “system black” event in recent memory. This incident caused traffic signals to fail, mobile networks to stop working, petrol stations to be unable to pump fuel, and supermarkets to halt payment processing. Madrid’s metro also came to a standstill, leaving passengers stranded. Despite initial blame on solar energy for the crisis, Spain's shift to renewables has since helped protect the country from gas price increases linked to the war in the Middle East.
