- Blackout Impact: A sudden outage on April 28 cut 15 GW, about 60% of Spain’s electricity, disrupting the entire peninsula.
- Government Response: PM Sánchez urged patience, citing ongoing analysis of over 756 million data points with no confirmed link to renewables.
- Political Tensions: Opposition parties slammed the government’s handling and called for a review of Spain’s nuclear phase-out plans.
Prime Minister Pedro Sánchez urged lawmakers to remain patient as Spain continues investigating a massive power outage that struck the Iberian Peninsula on April 28.
The blackout cut 15 gigawatts from the grid, slashing around 60% of the country’s electricity usage. Officials called the event “unprecedented.”
Speaking before the Congress of Deputies on Tuesday, Sánchez said authorities had not found any link between the blackout and Spain’s growing renewable energy capacity.
“We need time to examine the facts,” he said. “We won’t draw early conclusions.”
The power cut occurred at 12:33 p.m. local time and disrupted the electricity supply across the peninsula. Engineers recorded three disturbances within 30 seconds.
The first disturbance appeared in southern Spain. The second and third followed in the southwest. The grid handled the first two, but the third triggered a collapse in system stability.
Sánchez said analysts are reviewing 756 million technical data points. He insisted the government would only release findings after the complete analysis.
Opposition parties, however, criticised the government’s reaction. Partido Popular leader Alberto Núñez Feijóo accused Sánchez of mishandling the crisis. He demanded immediate resignations.
Other lawmakers challenged Spain’s plan to phase out nuclear power. They argued that the blackout exposed the need for stable baseload power. Spain still operates five nuclear reactors, which the current plan aims to decommission gradually.
Minister for the Ecological Transition Sara Aagesen confirmed that three technical faults caused the incident. She declined to provide further details about their origin.
She said investigators had not confirmed whether a surge in renewable generation played a role, but they have not ruled it out either.
The blackout sparked renewed debate over grid stability during Spain’s clean energy shift. As the country adds solar and wind power, experts warn that it must reinforce the grid to handle new pressures.
Spain’s investment in renewables continues to rise. Solar and wind now contribute a significant share of national power. Critics argue that the government has not modernised the grid fast enough.
Energy experts say sudden shifts in electricity flow can stress systems. These risks grow when backup sources like nuclear or gas remain limited.
Sánchez reaffirmed his government’s commitment to renewable energy. But he also acknowledged the need to boost infrastructure and prepare the grid for future demands.
“This event must lead to better safeguards,” he said. “We must prevent this from repeating.”
The Prime Minister also noted that the government had started working with European partners to improve regional grid coordination and response.
So far, officials have not set a deadline for the investigation. They plan to release a final report after completing the full technical review.
In the meantime, pressure continues to mount. Lawmakers and the public want clarity. The April 28 outage is among the worst in Spain’s energy history. The search for answers continues.
