Redeia used advanced simulation to test anti-cascading transmission towers under extreme multi-tower collapse scenarios. The results confirm that current Spanish grid design standards effectively prevent cascading failures and support overall grid resilience.

Spanish high-voltage electricity grid operator Redeia announced that its technology subsidiary Elewit has partnered with engineering software firm Akselos to develop an advanced simulation project assessing the structural behaviour of anti-cascading towers in overhead transmission lines under extreme, sequential collapse scenarios.
The initiative has validated existing design criteria used across the Spanish transmission grid and strengthened technical assessments of infrastructure resilience under exceptional loading conditions.
