Iberdrola’s Núñez de Balboa Plant: Cause of Spanish Blackout?

by Emma Walker – News Editor June 18, 2025

written by Emma Walker – News Editor

Here’s a summary of the key points from the provided text, focusing on the blackout and the finger-pointing:

The Blackout: A significant blackout occurred, and an examination is underway to determine the cause and prevent future occurrences. The initial investigation points to a forced oscillation originating in a photovoltaic plant in Badajoz.

Ree‘s Investigation: Ree (Red Eléctrica de España), the system operator, is required to publish a report on the blackout. They claim the malfunction at the Núñez de Balboa photovoltaic plant was the beginning of the chain of events.

Iberdrola‘s Defense: iberdrola, a major electricity company, denies responsibility and claims its actions were “impeccable.” They accuse Ree of “reckless and negligent” management and suggest Ree is confusing the consequences with the causes.Iberdrola’s executive president and CEO have both publicly stated that Ree is ultimately responsible for maintaining the electricity supply. Government’s Perspective: The government, through the vice president and minister for ecological transition, points to “bad planning” by Ree in the reserve power market (gas and nuclear). They also criticize the reserve market’s functionality, noting that nuclear reactors and gas cycles weren’t regulating tension as they should have been.

Tension Regulation Failure: Ree’s Operation Director and non-executive president stated that the blackout could have been avoided if the plants had properly controlled the tension.

Renewable Plant Disconnections: The government also cites “undue” disconnections of renewable generation plants as a contributing factor. Ree acknowledges this “waterfall shot of renewable generation plants” but is anonymizing the specific companies involved.

Outdated Regulations: The article highlights the lack of updated mechanisms for renewable tension control, referencing a 25-year-old operation procedure that has been pending approval sence 2021.

Call for Action: Ree calls for all generation facilities with tension control capabilities to activate them and for penalties for breaches.

* Núñez de Balboa Plant: The article mentions Iberdrola’s Núñez de Balboa photovoltaic plant in Badajoz, which was once the largest in Europe. While the initial investigation points to this plant, the article emphasizes that it was only the beginning of the chain of events.In essence, the article describes a complex situation where multiple parties are pointing fingers at each other in the wake of a major blackout. Ree blames a photovoltaic plant and failures in the reserve power market, Iberdrola denies responsibility and blames Ree, and the government points to planning failures and regulatory shortcomings.
