2025 Iberian Peninsula Blackout
After an unprecedented power outage hit Spain, Portugal, and parts of France last week, many in the media speculated that the large amounts of renewable energy in the Iberian system was to blame for the blackout.
The exact cause of the grid collapse is not yet known, but at 12:33 p.m. on April 28, electricity generation in Spain dropped rapidly from around 27 gigawatts to just over 12 gigawatts. The sudden drop in grid load destabilized electricity flows, resulting in a peninsula wide power outage.
At the time of the incident, Spain and Portugal were sourcing about 80 percent of their electricity from wind and solar, leading to the speculation that the grid could have been overloaded with renewable energy.
While renewables are well known for being more intermittent than generation from fossil fuels, the consensus amongst grid experts is that the generation source had nothing to do with this week's blackout.
