Spain’s energy grid operator and the nation’s electrical energy corporations traded blame on Wednesday over the April blackout that crippled the Iberian Peninsula, a day after a long-awaited authorities report highlighted their accountability.
The persevering with row is more likely to lengthen debate over one among Europe’s largest-ever energy outages, which raised doubts about Spain’s dedication to renewable vitality and scheduled phase-out of nuclear energy.

Overvoltage is when there may be an excessive amount of electrical voltage in a community, overloading gear and forcing protecting methods to close down elements of the grid.
The federal government stated the system “lacked enough voltage management capability” and that Spanish grid operator Purple Eléctrica (REE) and unnamed vitality corporations disconnected their crops “inappropriately… to guard their installations”.
REE had lowered its capability to manage pressure that day, whereas electrical energy corporations didn’t contribute as a lot as anticipated to manage voltage by their energy stations, based on the report.
REE revealed its personal report on Wednesday and stated it “carried out the related calculations to schedule technical constraints, at all times making certain that every one teams adjust to the obligations imposed by present rules”.
If vitality producers liable for regulating the voltage “had met their pressure management obligations… we’d not have had a blackout”, REE’s operations director Concha Sánchez instructed a information convention.
Aelec, an business affiliation representing energy corporations together with sector giants Iberdrola and Endesa, stated controlling pressure “falls on Purple Eléctrica, because the system operator”.
“We’ve proof that energy stations of Aelec members met the regulatory necessities when it comes to controlling pressure… even working above the regulatory obligations to contribute to the steadiness of the electrical system,” it stated in a press release.
REE “had sufficient sources to ensure the management of voltage… which it nonetheless determined to not dispatch”, added Aelec, saying the operator “left the system in a scenario of vulnerability”.
