Marshall is an 'Electricity System Engineer' with almost forty years' experience in design, asset management and construction, including hydro power stations, AC transmission substations, HVDC converter stations and synchronous condensers. Over his career he has worked for the Electricity Division of the Ministry of Energy, Electricity Corporation New Zealand (NZ), Design Power and as 'Principal Engineer' (retired end of 2018) with Transpower. He is a chartered Engineer and Fellow of both EngineersNZ and the Institution of Engineering and Technology (IET) United Kingdom (UK).

Marshall has a breadth and depth of knowledge and experience that every engineer should aspire to.

His areas of special expertise include strategic asset management, risk management, incident investigation, corrective actions management, performance analysis and economic/technical regulatory submissions. Marshall is a champion of asset and risk management and in the area of graduate engineering education.

In his role as a Practice Area Assessor for the professional assessment process run by Engineering New Zealand, he played a major role in Transpower's Graduate Engineer Programme, by being Engineering champion and leader of the programme from 2001 to 2008. Marshall's involvement in career development of younger engineers has included being a mentor for many individuals over the years.

Marshall's expertise is recognised within Transpower and the EEA has been fortunate to have benefited from his input, passion and enthusiasm. He joined the EEA in 2001 and immediately played an active role in the work of the Association, which was off the back of the excellent work he did for Transpower. The EEA would like to acknowledge Transpower for sharing and supporting Marshall and his work for the EEA.

Marshall's work in Asset Strategy Development particularly all main primary equipment types in substations;

• his work in Asset Health Model development - including development of asset health models for substation power transformers, outdoor circuit breakers, outdoor instrument transformers, indoor switchgear, power cables;
• his work in Asset Management System development particularly enabling Transpower to gain accreditation to the PAS55 Asset Management specification in July 2014,

can all be found in some form in the work outputs of the EEA Asset Management Group (AMG) and publications of the EEA.

As a regular member and contributor to the work of the EEA's AMG, including the development and publication of various industry guides, these four key EEA guides have been significantly influenced by Marshall input; EEA's Asset Management Maturity Assessment Tool (AMMAT) Guide, Asset Health Indicator Guide, Safety in Design Guide and Security of Supply Guide. All have large gems of knowledge relating to Marshalls knowledge of what 'good' assets and asset management should look like. These documents are evolving as asset management becomes mainstream and are used by industry and our regulators to measure progress of our industry in these areas.

Marshall has been a big part of the work of the EEA' s AMG and our now strong focus on what 'good' Asset Management is. It is the start of a journey which will have long term benefits to our industry and customers. His experience, wisdom, insight and technical knowledge have greatly helped the EEA, and benefitted our whole industry.

In 2016 as part of Marshall nomination as Energy Engineer of the Year, Mike Whaley EEA Executive Member and Chair of the AMG described the quintessential Marshall …

"he is pragmatic, versatile and articulate …he shows an infectious enthusiasm for projects that he believes will enable organisations to make a better contribution to our long term societal wellbeing".

The EEA would like to acknowledge and thank Lyn Marshall' s wife. As behind every successful person is an equally successful and supportive partner and family. Thanks for your significant support of Marshall and his industry work.
