The objective of this project is to build on the expertise and research that already exists for other sectors within the United Kingdom and contextualise this work in order to define how this could affect the Great Britain Electricity Transmission System. This project will be deemed successful on the completion, and publication of the report into High Impact, Low Probability events and the effect on the Great Britain Electricity Transmission System.

Currently, the concept of High Impact, Low Probability (HILP) (whilst understood as an abstract concept), is not clearly defined in terms of its incorporation into Asset Management tools for use within the utilities industry. HILP is much better understood in terms of how it related to other industries, such as the nuclear industry. There are few examples of how HILP events impact on infrastructure, with possible examples being hurricane Katrina in the United States of America, and closer to the United Kingdom, the large scale outages in Italy and Sweden. A clear understanding about how HILP should be defined and treated is required to help the Transmission Owners undertake world class asset management, and to mitigate HILP risks impact on the public. This is a critical element to the Network Output Measures methodology, and will be used by Scottish Power Transmission and Scottish Hydro Electric Transmission.
