Ten years of renewable electricity policies in Spain: An analysis of successive feed-in tariff reforms

Spain has been one of the most successful countries in the public promotion of electricity from renewable energy sources (RES-E), particularly wind electricity. This support has been based on a feed-in tariff (FIT) scheme. Although the basic structure of the system was implemented in 1998, it has been modified in 2004 and 2007. This paper provides an overview of the last 10 years of RES-E promotion in Spain, focusing on the FIT system and analysing the main differences and improvements of the three FIT systems. A political economy approach, which considers the interactions between key stakeholders in RES-E promotion, is used to interpret the actual outcomes of successive FIT reforms and their main design elements.
