A widespread power outage upended life for millions across Spain and Portugal — and, briefly, parts of France — on Monday.

Traffic lights went dark at busy intersections. Trains stopped in the middle of a workday. And long lines formed at A.T.M.s and grocery stores, where credit card readers stopped working.

By Tuesday morning, the outage was mostly over, but the cause was still under investigation.

Power has mostly been restored to the region

Spain’s national power company said early Tuesday that nearly all power demand in Peninsular Spain had been met by 6 a.m.

Portugal’s electricity and gas supplier, REN, said that power had been restored to all of its substations by late Monday.

The electrical grid operator in France, where the outage briefly affected households in the Basque region, said all power had been restored.
