Much has been done since the launch of the SET Plan in 2008. In 2013 it was decided that the updated technology roadmaps of the SET Plan should be consolidated into a single document in order to tackle the silo approach to energy technologies and to create an overview of an integrated European energy system. “Towards an integrated roadmap”, published in 2014, was the result of an extensive consultation process, and identified a portfolio of around 450 research and innovation (R&I) actions for the transition to a low carbon energy system. It was then time to set priorities and to choose joint actions to be implemented together with stakeholders, member states and associated countries (MS/ACs), along with the European Commission (EC). Work has been ongoing since the beginning of 2015 to define common agreed targets in the form of declarations of intent, and R&I actions in implementation plans.
