The data analysis, modelling, engineering, planning, designing, construction and operations expertise that will be developed by local and regional firms just to implement the Green Transformers concept alone, if appropriately nurtured and marketed, could be the foundation for making Sydney one of the leading centres in tri-generation technology. The City recently released a Decentralised Energy Master Plan, one of five Master Plans that together will comprise the Green Infrastructure Plan that determines the pathway for achieving the City’s Vision. Although the Green Transformers concept was the brainchild of UK energy expert Allan Jones, the Decentralised Energy Plan was prepared by a consortium of three Australian companies using metered electricity and gas consumption data that was provided by Energy Australia and Jemena.115 By building the expertise of local companies, rather than by continuing to import knowledge from abroad, the City is creating the beginnings of a local supply chain of talent and experience.
