dc.description.abstractThe Spanish electricity regulatory framework states that the regulated sectors must be remunerated through a reasonable rate of return, calculated as a spread to be added to the average government bonds yield. In that context, the objective of this work is to use the well-known financial model of the Weighted Average Cost of Capital (WACC) to approximate the allowed rate of return for renewable energy generation and generation in the isolated energy systems. As of today, the allowed rate of return has been set without any clear methodology. This work pretends to provide the regulator with a replicable methodology that can be used in the following regulatory periods and that is clear to all stakeholders. The WACC / CAPM model is selected because of its widespread use among energy regulators and within different industries. The methodology followed consisted on an extensive analysis of the Spanish regulatory framework and a comprehensive benchmarking of selected European cases that could provide additional insights and research elements. Although in general this work has relied on the WACC /CAPM model, it has been supplemented: in spite of its extensive use and strong grounding in financial theory, the WACC/CAPM model has certain limitations that make it unsuitable as the sole model for assessing rates of return to renewable projects. To tackle some of these insufficiencies, the model has been complemented to include asymmetric risks and price risk. A liquidity test was also added to the methodology. In the same way, it was decided that the peer group of companies used to calculate the rate of return for generation in the isolated systems will be the same as the one used for transmission and distribution activities. Regarding the methodological choices to the CAPM, like frequency of the data or reference market used, a complete analysis is presented. The results suggest that the WACC/CAPM based rates of return are lower (in approximately 60bps) than the allowed rates in the current regulatory framework. This can be explained through the differences in the economic environment when those rates were set and nowadays, even though historical data of the past 6 years have been considered. These differences in the economic situation should be taken into account on the next regulatory period. Regarding the existing spread between the rate for renewables and the rest of regulated activities (Namely, T&D and Isolated Systems) the obtained results are in line with the present regulatory framework, with a difference of about 100bps.es_ES
