Dogmatisms are of no use in preventing blackouts.

The lack of comparable precedents for the national blackout requires a dogmatic analysis of what happened on Monday to ensure it truly doesn't happen again in the future.

The government is resisting reviewing its climate policy after the unprecedented blackout that affected the entire Iberian Peninsula last Monday. Third Vice President and Minister for Ecological Transition, Sara Aagesen, yesterday staunchly defended renewable energy as the main pillar of the national electricity system despite evidence that the sudden loss of generation that caused the collapse occurred after several photovoltaic plants went offline amid the wholesale price chaos.

The thesis of the PSOE and Sumar executive, championed by Pedro Sánchez even before the data from the sector's companies was available, is that the majority share of renewable sources in electricity production did not contribute to the enormous fluctuations the grid suffered in the hours leading up to the fatal crisis. Aagesen used as an authoritative argument the fact that the energy mix on Monday morning was very similar to that of other days when the system operated normally and did not reach the peaks reached last summer.

But the truth is that Redeia, the grid management company, imposed a very different distribution of sources on Tuesday during the gradual recovery of power supply across the country, with a greater emphasis on combined cycle plants—which exceeded 25% of the total—and nuclear power plants to the detriment of photovoltaic and wind energy, with the aim of ensuring system stability. The lack of comparable precedents with the national blackout requires a non-dogmatic analysis of what happened on Monday to ensure it truly doesn't happen again in the future.
