This document seeks to analyse the renewable energy auction mechanisms applied in the Mediterranean basin and on the international level. It describes various types and aspects of renewable energy auction schemes, drawing on the actual experiences of the countries under study. It also assesses the applicability of different auction types to renewable support under different market countries, identifying the strengths and weakness of RES-E auctions. Furthermore, it determines the auction types and design specifications that suit particular requirements and policy targets in each country under study. Additionally, through an analysis of empirical experiences and certain case studies, the most effective practices in designing auctions for renewable support are identified.
