Power outage in Spain/ Red Eléctrica Española warns of risks associated with renewable energy sources

Beatriz Corredor, president of Red Eléctrica Española (REE), Spain's electricity grid operator, said it was "not correct" to link Monday's giant outage in the Iberian Peninsula to the large share of renewable energy sources in Spain's total electricity production.
However, the parent management company had warned in a recent report about the risks of "serious" power outages due to the "strong penetration of renewable energy sources" in the country.
"The strong penetration of renewable energy generation without the necessary technical capabilities to adequately handle outages could cause production interruptions," warned Redeia, the parent company of Red Eléctrica Española (REE), in the financial report for the 2024 annual results published at the end of February.
These outages "could become serious and go so far as to cause an imbalance between production and demand, which would significantly affect electricity supply," according to the report, in which Redeia stressed that the risk is "short- or medium-term."
Today, in her interview with the Cadena SER radio network, the president of REE insisted that production from renewable sources "is safe" and "the association of such a serious incident on Monday with a penetration of renewable sources in production is not correct", assuring that the financial report published in February did nothing more than record all possible consecutive risks, as required by law.
"Renewable energy sources operate sustainably, they already have mechanisms that allow them to function in practice like 'conventional' technologies," said Beatriz Corredor.
In its 380-page report, Redeia particularly highlighted two problems related to the energy transition: the presence of smaller power plants, with lower adaptation capacities, and the consequences of the closure of conventional power plants (natural gas, coal, nuclear power).
“The loss of sustainable production associated with the closure of power plants could lead to greater difficulties in system operation, increased production constraints and technical limitations, as well as a possible impact on supply. The risk of an attack or incident affecting information systems would have consequences for Spain's electricity supply and would damage Redeia's reputation,” the Redeia report warned.
Many possibilities have been discussed in the last 48 hours about the causes of the gigantic damage that caused chaos in Spain and Portugal. Among them is a cyber attack. However, this hypothesis has been ruled out by REE, which assures that the exact cause of the damage remains unknown.
