Introduction: This project involves the deployment of a previously developed methodology to quantify network risk and to develop a network risk modelling assessment tool. This work takes the outputs of the previous network risk modelling project and seeks to embed the results into Northern Powergrid's business processes through a process of casestudy development and learning and is designed to bridge the technology readiness from 4 to 8. The project is 50% funded through the Technology Strategy Boards Knowledge Transfer Partnership (KTP) programme.

Objectives: A number of issues arising in recent years have tended to increase the level of network risk, and therefore interruptions in supply including:

• Severe weather conditions are occurring more frequently

• Customer needs and expectations are increasing, particularly at times of network duress

• Decreasing reliability of an ageing infrastructure

• The additional demands on the network caused by distributed generation

• Increasing levels of both accidental and deliberate damage

• Increasing utilisation of distribution networks expected over the next 20 years due to increasing penetration of Electric Vehicles (EV) and domestic heat pumps.

It is essential to contain and mitigate this increased risk by scientific and accurate evaluation of that risk under different circumstances.

A reliable and acceptable way of measuring the expected network was developed in the first phase of the network risk project. This second phase is designed to better understand how to use this knowledge in real network situations and decision making. The project will then further develop this knowledge into a set of tools, probably IT enabled,
