This thesis examines the opportunities for better asset management within the electricity distribution industry. The project partner, a supplier of distribution products, observed their customers are often purchasing incorrect equipment for maintenance operations. This observation led the project partner to believe a lack of accurate asset knowledge exists within these electricity distribution businesses (EDBs). Coupled with the information that much of the installed asset base of these EDBs is approaching end of life, it was proposed to investigate the suspected lack of asset condition and type knowledge with the intention of developing the Infrastructure Asset Diagnostic Tool (IADT). A literature review was conducted to determine the current state of asset diagnostics within the electricity distribution industry. The principles of lean start-up business development have been used to isolate the most needed technology within the New Zealand marketplace through interviews with industry personnel. These interviews helped identify a possible Minimum Viable Product (MVP) for the IADT, and also indicated that providing the IADT as a professional service would be the most appropriate model for the MVP variant. Condition and type knowledge of wooden poles, conductors and line hardware was found to be the most lacking. It was recommended to focus product development on the assessment of these assets. The project partner has contracted two smart tool suppliers for the analysis of poles and conductor clearances. These products were then integrated to enable accurate assessments of wooden poles. An additional product identified as an aside during the interviews, was for a simple pole designing application which could be used in the field. An existing product from one of the smart tool suppliers contracted can fulfil this requirement. Possible benefits from IADT use were calculated for a sample EDB. These calculations indicated accurate condition assessment of wooden poles could lead to a saving of up to $5.4 million per year. This saving would equate to a possible reduction in time for securing pole integrity on this network from 30.8 years to just 5.9 years through more effective use of available funding. This reduction would lead to enhanced network reliability and improved public safety in a much shorter time frame than present, therefore this study recommends implementing the MVP form of the IADT at an initial EDB.
