Spain could face another wave of power outages

Spain’s grid operator, Red Eléctrica, has warned that the country could be on the verge of another blackout after detecting “abrupt voltage variations” across the system for the past two weeks, Euronews writes.

The warning comes six months after an outage in April left 60 million people in Spain and Portugal without power for more than 10 hours.

The European Network of Transmission System Operators for Electricity said in a report last Friday that the blackout was triggered by overvoltage, as the grid struggled to absorb sudden power losses.

Red Eléctrica has linked the unusual fluctuations recently detected in the electricity grid to sudden changes in renewable generation and the response time of facilities responsible for dynamic voltage control.
