Abstract
The Common Network Asset Indices Methodology (CNAIM) is a common framework of asset risk models developed jointly by all Electricity Distribution Network Operators (DNOs) and their regulator OFGEM (Office of Gas and Electricity Markets) in Great Britain (GB) as part of the standard electricity distribution license. Not only does CNAIM provide a common framework for asset risk modelling across Great Britain, it also facilitates better communications between different operators, supports justification of complex asset investment, allows cross asset class trade-offs and can be used as part of a broader investment planning process.This paper presents the CNAIM initiative and discusses the constraints and challenges faced in the process of creating a meaningful common framework. We then briefly consider global adoption of CNAIM and related asset risk modelling methodologies. Finally, we discuss opportunities for using asset risk methodologies as part of an investment planning process that supports the organisation’s entire investment portfolio (e.g. risk driven, load growth, customer, IT, health and safety, fleet etc.).
