In the wake of one of the most severe blackouts in European history—paralyzing the Iberian Peninsula and exposing vulnerabilities in intermittent renewable energy—Poland is emerging as a model for combining energy security with digital development. By investing billions of euros in nuclear power and Small Modular Reactor (SMR) technologies, Poland is laying the foundation for a resilient energy infrastructure that supports data centers, digital services, and innovation. This approach positions the country as a regional leader in pragmatic and climate-conscious transformation, ensuring 21st-century economic stability.
Data Centers Resilient Amid Iberian Blackout
In late April, a massive power outage hit nearly the entire Iberian Peninsula, leaving millions in Spain and Portugal without electricity for over 24 hours. The blackout disrupted public services, daily life, and business operations, with urban transport systems halted and digital services—including mobile networks and the internet—interrupted, resulting in significant economic and operational losses.
Initial analysis points to a complex chain of events rather than a single cause. At the time of the failure, the Iberian power system relied heavily on renewable sources, particularly solar energy, which accounted for over half of electricity generation. A sudden 15 GW loss of power—believed to stem from automatic disconnections of large-scale PV installations in southwestern Spain—led to system instability. Safety systems triggered the isolation of the Iberian Peninsula from the rest of the European grid, causing desynchronization and further shutdowns. The root cause remains under investigation, but experts agree that mass disconnections, lack of flexible reserves, and insufficient cross-border interconnections played critical roles.
Despite the crisis, data centers demonstrated exceptional resilience, maintaining continuity of service thanks to advanced backup systems—diesel generators and battery arrays. Their performance highlighted the importance of professional energy management in ensuring the reliability of essential digital infrastructure.
A Catalyst for Energy Reform
The blackout underscored how critical uninterrupted electricity supply is to modern life, prompting a reassessment of current energy strategies across Europe. While the shift toward renewables remains vital for climate goals, the incident highlighted the risks of overreliance on intermittent sources without adequate balancing mechanisms. As digitalization accelerates, particularly in tech-driven sectors like data centers and AI, the need for reliable, low-carbon base-load power becomes even more pressing.
Countries like Germany and Switzerland are now rethinking their anti-nuclear policies. Germany, which shut down its last three nuclear reactors in 2023, has reversed course under Chancellor Friedrich Merz, announcing plans to invest in SMR technologies. Similarly, Switzerland lifted its 2018 ban on new nuclear projects in 2024, planning to deploy flexible, scalable SMR units to safeguard energy security and support emerging sectors.
Globally, the consensus is shifting: stable and predictable power supply is foundational to the digital economy, and modern nuclear technologies, including SMRs, are essential tools to achieve that stability. Tech giants such as Google, AWS, and Microsoft have already signed power purchase agreements with low-emission nuclear facilities, viewing them as strategic assets for operational continuity and competitive advantage.
Poland’s Strategic Energy Response
Amid this evolving landscape, Poland is distinguishing itself with a long-term, realistic energy strategy. Central to this is a €15 billion investment in a 6–9 GW nuclear power plant in northern Poland. This project will not only reduce emissions but also guarantee reliable electricity regardless of weather or renewables’ variability.
Meanwhile, Polish private sector leaders—including Synthos and Orlen—are advancing SMR projects. These innovative, modular reactors are ideally suited for powering data centers and industrial clusters, offering predictable, decentralized energy closer to consumption points. SMRs can significantly lower transmission costs and enhance energy independence for large-scale digital infrastructure.
This strategic focus on clean, secure, and scalable energy is building a robust foundation for Poland’s digital future. Nuclear and SMR development supports data center investment, growth in advanced technology sectors, and deployment of AI and cloud services, all while aligning with climate commitments.
The Lesson from Iberia: Rational Energy Mix is Crucial
The Iberian blackout serves as a stark reminder: energy transition must be rooted in technical and operational realism. A well-balanced mix—capable of providing dependable base-load power—is essential. The future of Europe’s digital and industrial competitiveness relies not only on clean energy but also on secure grid operations, transparency, and resilience.
“Poland’s approach—combining climate ambition with practical safeguards—offers a blueprint for countries seeking a sustainable path between growth, security, and environmental responsibility,”
says Piotr Kowalski, Managing Director of the Polish Data Center Association.
In a world driven by AI, cloud computing, and data-centric innovation, energy reliability is not optional—it’s the bedrock of national competitiveness. With a clear vision and strong policy backing, Poland is emerging as a European leader in both energy and digital transformation.
