The Second Annual Synthesis Report brings together what we consider to be the most significant lessons learned while translating ambition into practice during the second year of LEO.

In Y2, progress has been made on the organisational, data and connectivity issues that emerged in Y1, with deeper understanding of the processes needed to gain flexibility from electric vehicles (EVs), connect up new distributed resources and operationalise demand-side response in institutional buildings. A major mapping exercise has expanded the quantity and quality of data available to the project. Detailed preparatory work is under way in sites around Oxfordshire – the Smart and Fair Neighbourhoods – where much of the local community-based work will be carried out. Project LEO is also now close to the point at which the TRANSITION trials can begin, taking the level of complexity and challenge up a level. This Summary sets out our main findings from Year 2 of LEO.
