Several recent studies have revealed that many High Voltage paper insulated power cables have already or will soon reach the end of their design life. The ageing process is not fully understood and will depend on external influences such as the type of soil it is buried in and how heavily the cable has been loaded.

The cost of replacing all of the cables is prohibitive in the short term, EDF Energy Networks is therefore seeking lower cost replacement strategies that will provide an efficient use of the remaining cable lifetime.

This aim of this project is to develop an innovative investment appraisal tool to prioritise network developments.

The issues being investigated by the project are:

  • Cable replacement & maintenance strategy

  • Ageing underground cable networks.
