A Multi-GW Energy Hub for Southern Europe: the Mediterranean Energy Island Proposal

Abstract

Offshore energy islands are getting increased attention due to the European decarbonization plans. In this context, the paper proposes a novel test case for a Mediterranean energy island where Italy, France and Spain exchange power through High Voltage Direct Current links. Steady-state optimal power flow simulations are performed for both a zonal and a nodal European-wide model and current cost benefit analysis (CBA) methodologies are used to evaluate the impact that such an investment would have on the European power grid in terms of total operational costs and $CO_{2}$ emissions. Lastly, possible further developments regarding the case study are discussed.
