The dimensions and velocity of the facility outage that introduced a lot of Spain and Portugal to a standstill on Monday have raised vital considerations each regionally and internationally.
That’s what Rystad Power acknowledged in a market replace despatched to Rigzone by the Rystad crew on Tuesday, which was penned by the corporate’s senior analyst Pratheeksha Ramdas.
“Spain’s nationwide grid operator, Purple Electrica (REE), and Portugal’s E-Redes are investigating the precise causes that led to irregular oscillations within the high-voltage traces and synchronization failures throughout the interconnected energy grid into France,” Rystad stated within the replace.

“As energy has now returned to massive elements of the area, the era combine in every nation performed a major function in each the failure and the restoration, preliminary Rystad Power evaluation reveals,” it added.
Rystad famous within the replace that the blackout started with a pointy fluctuation within the Spanish electrical energy grid, which it stated brought on all the electrical energy system to disconnect from the remainder of the European system at round 12.30pm on Monday.
“Inside minutes, the extreme fluctuations led to an entire collapse of the Spanish mainland’s electrical energy transmission grid,” Rystad highlighted.
“The failure had an instantaneous influence on on a regular basis life, with metro programs grounding to a halt throughout a number of cities, forcing emergency evacuations of underground transport, whereas airports, visitors indicators, and communications networks ceased functioning,” it added.
Rigzone skilled the facility outage in Lisbon, Portugal, first-hand, seeing a number of nonfunctional visitors lights and several other petrol stations closed across the space on Monday.
In a press release posted on its official X account on Monday, which was translated from Portuguese, the Portuguese authorities stated the GNR (Guarda Nacional Republicana) “appeals to the inhabitants to stay calm and serene, paying particular consideration to street visitors as a result of lack of visitors lights, and stays accessible to offer help by way of common contacts”.
An announcement posted on the federal government’s X account earlier on the identical day acknowledged that the GNR “is escorting the transport of gasoline to vital infrastructures, reminiscent of hospitals, and reinforcing policing and surveillance in business areas and gasoline stations”.
In a press release posted on its X account on Tuesday, the Portuguese authorities outlined that, when it comes to electrical energy, the nation was “related”, and that there was “standardized provide” when it comes to gasoline.
The Lead as much as the Outage
Rystad famous in its replace that, within the hours main as much as the outage, Spain’s electrical energy system was working close to noon peak ranges.
“Demand hovered round 27,500 megawatts (MW), largely equipped by a mixture of photo voltaic PV and onshore wind, pure gasoline, and a few residual nuclear era,” Rystad stated within the replace.
“Portugal was managing regular demand at round 8,000 MW, largely reliant on hydro, wind, and a few imported electrical energy from Spain,” it added.
“In the meantime, France, with its secure nuclear-heavy grid, maintained output above 55,000 MW and continued to export surplus electrical energy throughout its borders,” it continued.
Rystad stated within the replace that this regional interdependence is usually a energy however added that it grew to become a stress level on this occasion.
“Spain has historically relied closely on electrical energy imports from France, with the notable exception of 2022 when intensive nuclear upkeep in France briefly turned Spain right into a web exporter,” Rystad highlighted within the replace.
“Sometimes, Spain additionally transfers a portion of the imported energy to Portugal to assist stability the renewable-heavy grids of each nations. In 2024, Spain imported roughly 10.1 GWh from France, whereas its exports to Portugal rose to 14 GWh,” it added.
“Through the outage, France’s grid operator RTE activated automated security mechanisms that severed the interconnectors, isolating the Iberian Peninsula to stop the instability from spreading into Central Europe,” it continued.
“Because of this, Portugal was abruptly reduce off from exterior energy at a time of era failure, forcing it into an instantaneous power deficit. Spain, likewise, misplaced each French imports and its personal inner provide, making a shortfall of greater than 10,000 MW through the occasion,” it went on to state.
France’s Position
Rystad highlighted within the assertion that France’s function within the disaster was vital.
“Though its grid remained secure, the sudden drop in Iberian demand compelled the nation to briefly cut back era output and re-route its power flows,” Rystad stated.
“Notably, the Golfech Nuclear Energy Plant within the Occitanie area of France was reportedly compelled to close down round 12:30 – 12.45pm – the identical time the Iberian outage occurred – indicating a possible hyperlink by way of grid-wide frequency disturbance,” it added.
“As soon as stability was partially restored in Spain, France resumed restricted exports to help with restoration. By late afternoon, France was able to export again into Spain, serving to to jumpstart grid rebalancing and permitting Spain to help Portugal by way of secondary interconnection traces,” it continued.
Technology Combine
Rystad went on to state within the replace that the era combine in every nation performed a major function.
“Portugal’s renewable era was hit the toughest, with wind output collapsing by greater than 54 % through the outage,” Rystad stated within the replace.
“Excessive photo voltaic era additionally contributed to preliminary grid fluctuations, as photo voltaic accounted for round 29 % of Spain’s whole era on the time of the occasion, making the system extra delicate to voltage instability,” it added.
“France’s nuclear fleet, nevertheless, offered regular baseload era all through the occasion, giving it the power to reply swiftly as soon as interconnectors had been re-engaged,” it continued.
Rystad highlighted in its replace that, by the tip of Monday, energy was partially restored throughout the Iberian Peninsula. In a single a part of Lisbon, Rigzone noticed energy return on Monday night to the sound of cheers from residents.
“The provision-demand hole through the vital 2–3 hour window left tens of millions with out electrical energy and highlighted how dependent the area has develop into on cross-border balancing,” Rystad famous in its replace.
“Spain’s web energy change flipped from exporter to importer, whereas Portugal’s full reliance on imported energy throughout grid stress uncovered a scarcity of home flexibility and storage,” it added.
“France, in the meantime, demonstrated the advantages of a secure, diversified and partially insulated grid but additionally confronted the problem of adjusting flows with out advance discover,” it went on to state.
Rigzone has contacted Spain’s Ministerio para la Transición Ecológica y el Reto Demográfico, REE, Portugal’s Ministério do Ambiente e Energia, E-Redes, France’s Ministry of Trade and Power, and the market companies division of RTE for touch upon Rystad’s replace. On the time of writing, not one of the above have responded to Rigzone.
