A recent blackout in Spain and Portugal was attributed to extreme frequency fluctuations that caused widespread power outages. Eduardo Prieto, head of the Spanish electricity operator (REE), reported two incidents occurring within 1.5 seconds that disrupted grid balance, affecting nearly half of the operational capacity. While theories about cyberattacks circulated, Prieto indicated that solar power plants might have contributed to this failure through a domino effect. Renewable energy advocates face criticism, as oversupply of solar energy comes into question regarding the reliability of power supply.
"Extreme frequency fluctuation caused power outages in Spain and Portugal, with up to 15 GW of plant capacity affected. Solar plants may have triggered cascading failures."
"Two separate incidents occurred within 1.5 seconds, leading to significant deviations in grid frequency, which resulted in a domino effect across the power plants."
