Spain’s grid operator has denied that solar power was to blame for the country’s worst blackout, as Prime Minister Pedro Sanchez faces increasing pressure to explain what went wrong.
Red Electrica de Espana (REE) on Wednesday said the source of the outage had been narrowed down to two separate incidents of loss of generation in substations in southwestern Spain, but stressed that it was too early to draw conclusions, as it had yet to identify their exact location.
REE’s head, former Socialist minister Beatriz Corredor, told Cadena SER radio that it was wrong to blame the outage on Spain’s high share of renewable energy.
“These technologies are already stable, and they have systems that allow them to operate as a conventional generation system without any safety issues,” she said, adding she was not considering resigning.
Life across the Iberian Peninsula was returning to normal after a power outage halted trains, shut airports and trapped people in lifts in Spain and Portugal on Monday.
Just before the system crashed, Spain’s solar energy accounted for 53 percent of electricity production, wind for almost 11 percent and nuclear and gas for 15 percent, according to REE data.
Political opponents criticised Sanchez for taking too long to explain the blackout and suggested he was covering up for failings, after his left-wing coalition government invested in expanding the renewable energy sector.
