This project will draw on work from 'The politics of UK and European energy policy interactions' project and pathways from Theme 1 to consider what market developments have been proposed at a European level and which could be implemented under different conditions. Through integrated engineering and economic analysis led by Prof Richard Green at Imperial College, the project will test the likely effects of different market developments under a range of credible future energy pathways and analyse the effectiveness, from a UK perspective, of different sets of Europe-wide trading arrangements thus helping to inform UK engagement with European initiatives.
