The Conference Theme is "Network efficiencies and opportunities in an increasingly complex energy landscape" Electricity networks which consist of both transmission and distribution systems face ongoing and serious challenges in the years ahead. The requirements of planning, designing, constructing and operating systems remain the same, however we now have a radically different environment. This includes such things as very different generation mixes, more Power Electronics controlled loads and two-way energy flows. In addition, all must be managed at reduced cost whilst still ensuring reliability, adequate power quality and customer service. Issues such as ageing infrastructure, staff skills and staff depletion have to be managed, as well as the effects of extreme weather conditions such as bushfires and floods. It is indeed a new world and we need to learn from others and discuss with them the best ways to proceed.
