Portugal aims to develop industrial activities linked to the renewable technology sector and to become a net exporter of such technologies, especially wind and solar power. An industrial cluster linked to wind power has been developed, with a budget of EUR 1 750 million, involving the creation of approximately 1 700 direct and 4 500 indirect jobs (IEA, 2009a). The principal instrument for promoting renewable electricity in Portugal is the so-called “special regime production” (PRE), whereby renewable-based power benefits from a feed-in tariff, i.e. an above-market price at which electricity is sold to the grid. The tariffs are based on a complex formula that takes account of the technology, environmental aspects and the inflation rate.25 They include minimum and maximum levels, according to the variations of the load on the grid, and are guaranteed for a fixed period (typically 15 years) and up to a certain production threshold (IEA, 2009a).
