A super grid connecting the two shores of the Mediterranean could help Europe meet its targets for integrating renewable energy. This paper assesses the business models for building a platform for wholesale renewable energy trade via electricity corridors linking the two regions of the Mediterranean basin. We demonstrate that the optimal framework for designing the corridor project is a long-term contractual agreement to coordinate bilaterally the necessary investments. Furthermore a hybrid governance structure requiring only limited regulatory adaptation seems to be the most efficient structure for facilitating investment in the corridor’s infrastructure.
