What caused the blackout in Spain and Portugal?
The blackout was caused by voltage surges that cascaded through the Iberian power grid. These surges disrupted the flow of electricity, leading to a widespread power failure affecting both countries. Investigations are ongoing to determine the exact trigger, but the initial reports point to a voltage surge as the root cause.

How are authorities fixing the power grid after the blackout?
Authorities are investing €137 million to strengthen the grid, including adding more black start stations and backup energy sources. These measures aim to improve the grid's resilience, allowing it to recover more quickly from future surges or failures and prevent similar blackouts.

What are black start stations and why are they important?
Black start stations are facilities that can restart the power grid without relying on external power sources. They are crucial for restoring electricity after a blackout. By increasing the number of black start stations, authorities can ensure a faster and more reliable recovery process in case of future outages.
