Understanding Cable Rejuvenation: A Modern Approach to Grid Reliability
Key Takeaway
Cable rejuvenation offers a crucial and cost-effective method to maintain and improve grid reliability by extending the life of existing underground infrastructure, directly benefiting developers and large power consumers reliant on stable power delivery.
AI Summary
- •Aging underground polyethylene (PE) and ethylene-propylene rubber (EPR) cables, some over 60 years old, are failing prematurely due to 'water treeing,' threatening grid reliability.
- •Traditional replacement of these cables is described as costly and labor-intensive, creating a significant challenge for grid operators.
- •Cable rejuvenation is presented as a modern, cost-effective solution to extend the lifespan of existing underground infrastructure, thereby enhancing overall grid reliability and stability for developers and large power consumers.

For more than 60 years, polyethylene (PE) and ethylene-propylene rubber (EPR) underground cables have powered communities, industries, and progress. The hope was these cables could last decades before needing to be replaced, but due to water treeing—microscopic moisture-induced formations that degrade insulation and threaten reliability, they’re aging more rapidly than expected. With traditional replacement being costly and labor-intensive, it was time for a new solution.
