Spain says April power outage caused by ‘overvoltage’

MADRID: A major power outage that struck the Iberian Peninsula in April was caused by “overvoltage” on the grid that led to “a chain reaction,” according to a government report released Tuesday. The blackout had “multiple” causes, Ecological Transition Minister Sara Aagesen told reporters following a cabinet meeting, adding the system “lacked sufficient voltage control capacity” that day. Overvoltage is when there is too much electrical voltage in a network, overloading equipment.
