Déjà vu: Less than six months after the country suffered Europe’s worst blackout in decades, Red Eléctrica says it’s seeing the same pattern of abrupt production shifts, especially from renewable power plants.
The operator asked regulators to allow temporary rules requiring more gas and thermal plants to stay on standby, giving the grid more control over voltage. Spain’s energy regulator will fast-track approval after a five-day feedback period.
