Recently, the Iberian Peninsula experienced a historic blackout. In a matter of seconds, the entire digital and energy infrastructure was paralyzed. Telecommunications were cut off, access to information was lost, purchases could no longer be made, cash withdrawals were impossible, and emergency services were unreachable. In Lisbon, the outage lasted up to 18 hours, while in other parts of the region, the situation returned to normal after around 10 hours.

The exact cause of the outage remains unclear. After swiftly ruling out a cyberattack, no definitive explanation has been confirmed. Meanwhile, alarmist narratives emerged, questioning the growing role of renewable energies and even suggesting that their development should be curbed.

Could Belgium Face a Similar Scenario?

While the risk of a blackout can never be entirely excluded, Belgium benefits from a much denser interconnection with neighboring countries, significantly strengthening its grid stability. This interconnectedness enables the compensation of imbalances through cross-border energy transfers—a benefit the Iberian Peninsula only partially enjoys.

Moreover, technologies associated with renewable energies are rapidly evolving toward greater intelligence and responsiveness. It is this transformation that now allows renewable production to go hand in hand with grid stability.

The Crucial Role of Smart Renewable Energies

Contrary to common misconceptions, renewable energies are not inherently unstable. They become major assets for energy resilience when coupled with intelligent energy management systems and storage capacities.

A large-scale solar power plant equipped with an advanced Energy Management System (EMS) offers several key advantages:

• Anticipating imbalances by analyzing grid data and responding to signals from infrastructure operators;
• Reacting in milliseconds through dynamic control of production or activation of storage systems;
• Absorbing or supplying power using batteries, depending on the grid's needs.
  
  These systems turn each production site into an active player in energy balancing, capable of adjusting its behavior in real time.

A Future-Oriented Model: Flexibility, Autonomy, and Security

The combination of renewable sources, distributed storage, and intelligent management technologies forms the foundation of tomorrow’s energy networks. This model not only accommodates a growing share of intermittent energy sources but also strengthens supply security.

In 2024, nearly 47% of Europe’s electricity consumption was covered by solar and wind energy. This share is expected to keep increasing in the years to come.

In the face of climate and geopolitical challenges, the goal should not be to slow this dynamic, but to support it with robust, flexible, and intelligent infrastructure solutions.

Turning Light into an Energy Shield

Rather than fearing the system’s limitations, efforts must focus on leveraging technological advances to improve installation resilience. By investing in smart solutions, integrating storage, and optimizing energy management, companies can not only gain autonomy, but also actively contribute to grid stability.

Recent events remind us that relying on centralized systems comes with vulnerabilities. But they also demonstrate that renewable energies—when well-orchestrated—provide concrete answers to these challenges.

Now is the time to adopt a forward-looking approach: more connected, more intelligent.
