pilot testing, international standards readiness.
Introduction
The EXTRASTRONG project was designed to fill critical gaps in our understanding of how extreme heat waves affect underground cables and joints – the fundamental infrastructure of urban distribution systems.
By combining experimental and theoretical approaches, we aim to provide actionable outcomes that enhance grid resilience, improve monitoring, and support investment decisions.
Six Strategic Objectives
Scientific excellence, standardized testing, and advanced analytics to future‑proof underground grids against extreme heat events.
Enhance knowledge
Contribute to a deeper understanding of how heat waves affect underground cables and joints – the fundamental infrastructure of urban distribution systems.
Standard measurement system
Develop a field deployable measurement setup that DSOs can use to monitor environmental conditions and prevent heat wave related failures.
International lab test procedure
Define a repeatable, standardised test procedure for evaluating the electrical resilience of cables and joints under heat wave conditions, ready for adoption by international standardisation bodies (e.g., CENELEC, IEC).
Design a test bench
Build a test bench capable of replicating various load and heat wave scenarios, enabling manufacturers to verify component compliance with the proposed test procedure.
Refine cable and joint models
Update existing thermal and electrical models to incorporate insulation degradation and ampacity changes caused by heat waves, improving prediction accuracy.
Statistical resilience framework
Provide a Monte Carlo based cost-benefit analysis framework that helps DSOs evaluate investments in grid hardening, reconfiguration, or alternative cable types under uncertain future climate conditions.
From Torino to the world — bridging research, industry and grid operators to ensure climate-resilient electricity networks for tomorrow's cities.
