Introduction: This process will consider:

• The quality of the network state estimation (in terms of load levels, voltage profile, line flows, and network continuity/configuration)

• The availability of condition assessment data characterising network assets

• The thoroughness with which current restoration procedures, both automatic and manual, used to reconnect supply following an outage, are documented.

Objectives: To establish the feasibility of completing a risk based assessment of the operational performance of a section of EDF Energy Networks’ network, based on current data resources available to describe network configuration and performance.
