Call Module 2026-01: Integrated energy system resilience in a changing environment

Europe’s energy system is becoming increasingly interconnected and reliant on renewable energy. While this transition improves sustainability, it also introduces new challenges for system reliability and security of supply.

This call module focuses on strengthening the resilience of integrated energy systems, defined here as coordinated infrastructures that combine multiple energy carriers, such as electricity, gas, and heating and cooling. These systems rely on the physical and digital integration of generation, storage, and demand to optimise system performance, sustainability, and reliability.

Proposals should address how energy systems can anticipate, withstand, and recover from disruptions that go beyond normal operating conditions. Key challenges:

• Structural vulnerabilities: weaknesses in generation, transmission, and distribution networks when operating beyond their design limits. These may arise from high shares of renewable energy sources (RES), increased variability, reduced system inertia, limited voltage control, and shortages in system flexibility.
   
• External threats: disruptions caused by external events such as extreme weather (e.g., storms, floods, snow, or heatwaves), cyberattacks, or sabotage.

Proposals should focus on situations that may threaten reliability and quality of supply if not adequately managed. The emphasis is on stressed, degraded or emergency system conditions, rather than normal system operation.

Proposals should address one or more stages of the system resilience cycle, from anticipation and preparation to recovery and adaptation.

Projects are expected to:

• Project start at TRL 3 or higher.
• Project end at least +1 TRL
