The aim of this project is to describe the expected evolution of the Spanish electricity sector in the coming decades, as well as to study the economic feasibility of solar PV and CCGT power generation plants in this context. First of all, an analysis of the Spanish electricity market has been carried out. The current energy situation has been also studied, both globally and nationally. Given the growing importance of renewable energies in the sector, the legislative development on renewables has been studied, as well as the impact they have generated in the sector and their different financing mechanisms. Based on the environmental objectives established by the European Union, the general lines of the expected energy transition in the Spanish electricity sector have been defined, estimating the installed capacity of the main generation technologies for the period 2020-2050, as well as their contribution in the generation mix. Likewise, an analysis of the price of electricity in the daily market has been carried out, from which a price prediction model has been developed. According to the results, the weight of renewables will increase progressively during the next decades, reaching in 2050 an approximate share of 90% in the generation mix. The expected load factor for CCGTs, on the other hand, will increase in the mid-term, whereas in the long-term will be reduced below the current values. The price of electricity, on the other hand, will increase significantly between 2020 and 2030, whereas as of this year will undergo a gradual but steady reduction. Given the expected relevance of solar PV and CCGT technologies in the future Spanish generation park, the economic feasibility of both technologies has been studied. In the case of the solar PV plant, an analytical model has been developed in MATLAB by which forecasts of the generation of the plant have been made. These results have been validated by the software SOLAR PV, making a comparison between both results. For the analysis of CCGT plant, the price in the adjustment markets has been studied, analysing its relationship with the price in the daily market. According to the results, both projects would be profitable. However, given the uncertainty inherent to forecasts of the price, alternative forecasts have been considered. Due to substantial differences in the mid-term, the main financial parameters of solar PV and CCGT power generation plants have been calculated again, considering in this case the alternative forecasts of the price. From this second analysis it has been concluded that, whereas the solar PV would not require any additional financing mechanism in order to be profitable, capacity payments would be indispensable in the case of the CCGT plant. It has been also concluded that, in the analysis of the economic feasibility of marginal technologies, such as CCGTs, the average price of the electricity in the markets is not a representative parameter.

The Energy Return on Energy Invested (EROI or EROEI) is the amount of energy acquired from a particular energy source divided by the energy expended, or invested, in obtaining that energy. EROI is an essential and seemingly simple measure of the usable energy or “energy profit” from the exploitation of an energy source, but it is not so easy to determine all of the energy expenditures that should be included in the calculation. Because EROI values are generally low for renewable energy sources, differences in these estimates can lead to sharply divergent conclusions about the viability of these energy technologies. This book presents the first complete energy analysis of a large-scale, real-world deployment of photovoltaic (PV) collection systems representing 3.5 GW of installed, grid-connected solar plants in Spain. The analysis includes all of the factors that limit and adjust the real electricity output through one full-year cycle, and all of the fossil fuel inputs required to achieve these results. The authors’ comprehensive analysis of energy inputs, which assigns energy cost estimates to all financial expenditures, yields EROI values that are less than half of those claimed by other investigators and by the solar industry. Sensitivity analysis is used to test various assumptions in deriving these EROI estimates. The results imply that the EROI of current, large-scale PV systems may be too low to seamlessly support an energy and economic transition away from fossil fuels. Given the pervasiveness of fossil fuel subsidies in the modern economy, a key conclusion is that all components of the system that brings solar power to the consumer, from manufacturing to product maintenance and life cycle, must be improved in terms of energy efficiency. The materials science of solar conversion efficiency is only one such component. Sunny Spain represented an ideal case study as the country had the highest penetration of solar PV energy at 2.3 percent of total national demand as well as state-of-the-art expertise in solar power including grid management of intermittent, modern renewable systems. This book, written by a uniquely qualified author team consisting of the chief engineer for several major photovoltaic projects in Spain and the world’s leading expert on the concept and application of EROI, provides a comprehensive understanding of the net energy available to society from energy sources in general and from functioning PV installations under real-world conditions in particular. The authors provide critical insight into the capacity of renewable energy sources to fill the foreseeable gap between world energy demand and depletion rates for fossil fuels. · Presents the first comprehensive study of the EROI of large-scale solar PV systems in a developed country · Uses real-world operational data rather than laboratory approximations and extrapolations · Describes the dependence of one alternative energy source on the goods and services of a fossil-fueled economy · Has global implications for the potential of renewable energy sources to replace dwindling reserves of fossil fuels · Written with the first-hand knowledge of the chief, on-site engineer for many solar installations in Spain together with the leader in the development and application of the concept of EROI

The present master thesis work deals with the techno-economic analysis of a combined PV-CSP utility scale power plant that operates to meet intermediate and peak load demand under the well-defined REIPPP price scheme in South Africa. For such analysis, a multi-objective optimization was carried out in order to find optimal plant designs for the selected market. Subsequently, the same optimization was performed for CSP alone and PV alone plants and its results used in a comparative analysis that allowed the economic feasibility of the PV-CSP combined plant to be assessed. The study is based on a utility scale Solar Tower Power Plant (STPPP) with thermal energy storage and a PV plant models previously developed, validated and implemented in an in-house tool developed in KTH for techno-economic modelling of power plants. Such models were coupled together for combined operation and a specific dispatch strategy for intermediate and peak load operation was developed. The resulting combined model was further verified by using data gathered from real PV-CSP projects currently under development and the dispatch strategy was tested by using newly implemented indicators. Additionally, a methodology for calculating the average tariff that must be granted to ensure a desired level of profitability (fixed IRR) under a Power Purchase Agreement (PPA) contract was implemented. The resulting indicator was used in the techno-economic analysis of the plant, together with other performance indicators such as CAPEX and capacity factor. The results of the multi-objective optimization show that, for the same dispatch strategy and tariff scheme, both the CSP alone and PV alone plants yielded lower average PPA prices and CAPEX than the PV-CSP hybrid. This was further confirmed by the fact that the PV capacity was minimized in all PV-CSP optimums, thus converging to a CSP only power plant. Furthermore, the CSP alone plant proved to be more flexible in varying its hourly and seasonal output levels on demand. PV alone optimum configurations all featured tracking systems to maximize power production during daytime and did not follow a peaking dispatch strategy due to the lack of a storage system. The PV-CSP hybrid solution scored higher values of capacity factor and performed better in meeting the dispatch strategy compared to the CSP alone and PV alone solutions, thus suggesting that the value of a combined plant can be increased when an operational strategy that maximizes capacity factors is sought (baseload), or when constraints are applied in terms of matching peak hours or meeting a fixed number operational hours per day.

The world's deserts are sufficiently large that, in theory, covering a fraction of their landmass with PV systems could generate many times the current primary global energy supply. In three parts, this study details the background and concept of VLS-PV, maps out a development path towards the realization of VLS-PV systems and provides firm recommendations to achieve long-term targets. This represents the first study to provide a concrete set of answers to the questions that must be addressed in order to secure and exploit the potential for VLS-PV technology and its global benefits.
