We need to understand the opportunities and challenges around policy, regulation, user engagement and digitalisation of energy systems to unlock the benefits of Smart Local Energy Systems (SLES). EnergyREV is a consortium of academics from 22 UK universities with the multi-disciplinary expertise to address these questions, identify evidence to inform change in both the UK and internationally and provide new tools and insights to accelerate the delivery and roll-out of these systems. We are doing this by considering the whole-system integration required for SLES.
