Failure modelling of overhead lines exposed to worsening gradual and instantaneous weather hazards due to climate change

Climate change is already causing transmission networks to face more frequent and intense weather-based hazards and risks, potentially affecting their reliability and resilience. It is vital that transmission network owners (TNOs) understand not only the potential impacts of changing individual hazards, but also the potential for compounding effects from multiple hazard types on system resilience. Sophisticated modelling of multi-hazard failure risks is needed.
