Accelerating grid resilience and reliability for a new energy era

The massive power outages that occurred in Spain on April 28, 2025, as well as the prolonged power cut in Berlin at the beginning of the year, highlighted a reality the energy sector can no longer ignore: our electric grids are under unprecedented pressure and must meet ever-higher demands.

Aging infrastructure, the acceleration of electrification, the rapid integration of renewable energy and the constant evolution of security threats require immediate action to manage the grid’s growing complexity.

Four interdependent trends are profoundly redefining how utility operators must plan, operate and invest to, literally, 'keep the lights on'. Understanding these trends and responding effectively is essential to ensure the resilience and reliability of the grid in the decades to come. In an increasingly interconnected society and economy, mastering this is now a necessity for the daily life of every citizen.

1. More sustainable models

Modernization is accelerating alongside a transition marked by more sustainable models. These two dynamics now converge. Regulations such as the revision of the European regulation on fluorinated gases, which will ban from 2026 the use of SF₆ in new medium-voltage equipment (up to 24 kV), are accelerating the adoption of cleaner, more advanced technologies.

As networks digitize and decentralize, their exposure to risks increases, making it essential to strengthen their protection at all levels.

The rapid sectoral shift to proven, SF₆-free alternatives demonstrates that operators no longer have to choose between sustainability and reliability. By investing in modern, environmentally friendly equipment that is often more reliable and less maintenance-intensive, they can both bolster grid resilience and progress toward decarbonization targets.

2. Towards greater energy reliability 

Grid security is no longer a one-dimensional challenge. The blackout that occurred on the Iberian Peninsula in 2025, caused by a cascade of technical failures, highlighted the need to strengthen the structural robustness of grids as well as voltage stability within infrastructures managing increasingly complex energy flows.

The outage in Berlin in January illustrated a very different form of threat: that of a deliberate physical attack. These two events testify to the dual vulnerability faced by grid operators (GRD). As infrastructures digitize and decentralize, their exposure to risks increases, making it essential to strengthen their protection at all levels.

3. Facing the tsunami of demand

Electricity consumption is entering a new phase of growth. The rise of artificial intelligence is driving the rapid expansion of data centers. According to some projections, notably those of McKinsey, these infrastructures could account for up to 5% of Europe’s total electricity consumption by 2030.

This new increase in demand adds to grids already heavily strained by the massive electrification of transport and heating, a transition nevertheless essential to meet climate goals. Existing infrastructures are thus being pushed well beyond their original design. To sustainably meet this growing demand, targeted modernizations and smarter load management strategies will soon become necessary.

Grid operators need more intelligent, automated infrastructure capable of responding in real time to growing complexity.

Determining where to start and how to direct investments remains complex. Faced with the multiplication of transformations affecting the sector, a continuous and coordinated strategic approach is indispensable. It becomes essential to prioritize interventions according to their impact and degree of urgency.

4. Necessary grid modernization

Grid operators need more intelligent, automated infrastructure capable of responding in real time to growing complexity. Digital technologies offer greater visibility and better control, while aiming for a high level of protection against cyberattacks.

Advanced analytics tools, digital twins and predictive maintenance are becoming indispensable to manage grid congestions and detect outages or potential threats before they occur. By deploying these solutions, operators can optimize the use of existing assets while laying the foundations for a more resilient, flexible grid capable of handling complex bidirectional energy flows from a multitude of decentralized sources.

The dangerous cost of inaction

The events that occurred in Spain and Berlin are not mere news items but warnings. Together, these four trends present an unambiguous conclusion: yesterday’s energy grid is not up to the challenges of tomorrow.

Ensuring a resilient, reliable and secure energy supply requires a coordinated effort in strategic investment, rapid innovation and strengthened security. In an increasingly electrified and digital world, the cost of inaction simply becomes too high.
