This paper is concerned with the independent production of electrical power based on renewable sources. Recently, new legislation has been published with the aim of creating the conditions for the renewables to become a more significant component of the generation mix. One of the main tools to enforce the increase in the penetration of renewable sources is the establishment of the so called “green tariffs”, that incorporate the environmental benefits provided by those producers. The paper is composed by three main parts. Firstly, some details concerning the Portuguese electrical system are given, including an assessment of the novel legislative framework. Then, a description of the new methodology used to compute the energy prices paid by the public system to the producers that convert renewable sources, is made. Finally, a case-study composed by three renewable installations is presented; some results concerning the processing of available data are shown, namely an estimation of the average energy selling prices from renewable producers to the public grid and the percentage distribution of the different parcels that compose the average prices.
