Why did the power grid fail?
According to the findings, voltage control systems malfunctioned, the grid lacked the flexibility and backup capacity needed to absorb fluctuations, and the increasing share of renewable energy failed to provide the grid inertia traditionally supplied by conventional power plants.
Did Red Eléctrica miscalculate power capacity?
Nearly two months after the unprecedented outage, the minister for ecological transition, Sara Aagesen, has presented a report on its causes. She said the partly state-owned grid operator, Red Eléctrica, had miscalculated the power capacity needs for that day, explaining that the "system did not have enough dynamic voltage capacity".
How many thermal power stations did Red Eléctrica programme?
The vice-president detailed that on 27 April the system operator, Red Eléctrica, programmed 10 thermal power stations throughout the country for dynamic voltage control the following day.
