Questions remain in wake of Iberian blackout report

The entire Iberian Peninsula experienced a power cut in April, with outages lasting up to 24 hours, as a combination of factors pushed Spain’s grid past the point of no return. The first report on the incident, published in June by a government-appointed committee, said a series of power surges led to a chain reaction of disconnections. Recriminations continue between stakeholders as the investigation proceeds and Spain accelerates plans to reinforce its grid.
