The objective of this project is to develop a new tool aimed at evaluating EU’s vulnerability to the different risks which might affect energy supplies, in order to help optimising the Union’s energy risk mitigation strategies. The project will therefore consist of developing energy security indicators for all the energy sources in order to identify the risk factors and quantify EU’s exposure to volume and price risks in the short and long terms, including the value consumers give to supply security. Costs and benefits of energy security will be evaluated for different energy demand scenarios to help policy makers building the most appropriate institutional, political and industrial parades.
