This document discusses smart grids, customer applications, and electric vehicles. It contains 3 key challenges: 1) consumers reacting to price rises by adopting solutions like solar panels, 2) the divergence between peak energy demand and overall energy growth continuing, and 3) additional cybersecurity risks needing to be addressed. The document outlines a smart metering trial involving 20,000 customers to validate infrastructure, provide consumer benefits, and reduce peak demand and environmental impacts. It describes various feedback technologies being tested, like in-home displays and customer portals. Key project milestones are given along with discussions of the smart metering architecture, benefits of 4G communication, and plans to test electric vehicle charging and demand management.
