The outage, blamed by operators on temperature variations, left tens of millions without electricity
Lights flickered back to life across most of Spain and Portugal on Tuesday after a massive blackout hit the Iberian peninsula, stranding passengers in trains and elevators while millions lost phone and internet coverage.
Electricity had been restored to nearly 90% of mainland Spain by early on Tuesday, the grid operator REE said. Power was restored overnight to around 6.2m households in Portugal out of 6.5m, according to the national electricity grid operator. Lights also came on again in Madrid and in Portugal’s capital, Lisbon.
