CO2 emissions play a crucial role in international politics. Countries enter into agreements to reduce the amount of pollution emitted into the atmosphere. Energy generation is one of the main contributors to pollution and is generally considered the main cause of climate change. Despite the interest in reducing
emissions, few studies have focused...
This paper offers an independent assessment of certain economic effects of the Iberian Exception (IE) which was introduced in June 2022 by the Spanish and Portuguese governments. Their stated aim was to reduce wholesale spot electricity prices (which were rising alarmingly due to tight international gas markets related to Russia s invasion of Ukrai...
This research attempts to determine the optimal size (in terms of profitability) of a photovoltaic (PV) plant that is going to be added to an existing wind installation. The analysis carried out is based on a real sample of 62 wind facilities located in 25 Spanish provinces in 2021. Given the hourly energy generated throughout the year by the wind...
This research proposes an empirical method to estimate the impact on the wholesale electricity market of an increase in the price of CO2 emission allowances. The current literature in this field is mainly focused on long-term simulation analyses, while this study carries out a short-term analysis with microdata from the electricity market. A higher...
This article provides an overview of high voltage direct current (HVDC) and high voltage alternating current (HVAC) power transmission alternatives. The use of HVDC systems currently represents an efficient alternative under certain conditions, mainly due to reduced converter costs, improved power system flexibility and higher economic efficiency f...
This study analyzes the determinants of the annual compensation of directors belonging to the boards of the Spanish companies that constitute the IBEX 35 stock index. We investigate the importance of observed and unobserved heterogeneity in explaining director compensation. Based on a three-level mixed effect model, our analysis includes time-invar...
Several research studies have shown that future sustainable electricity systems, mostly based on renewable
generation and storage, are feasible with today’s technologies and costs. However, recent episodes of extreme
weather conditions, probably associated with climate change, cast shades of doubt on whether the resulting
generation portfolios are...
Electricity arbitrage involves the storage of energy at times when prices are low, and offering it on the markets when prices are high. The development of renewable and energy storage technologies may provide a promising business opportunity for electricity arbitrage. In this regard, this study analyses the current viability of the electricity arbi...
Scheduled closure of coal-fired power plants will halve emissions in the electricity sector, although prices will be increased by 12%. To compensate for this increase, the Ministry for Ecological Transition and the Demographic Challenge will promote new renewable power.
The importance of electricity in people’s daily lives has made it an indispensable commodity in society. In electricity market, the price of electricity is the most important factor for each of those involved in it, therefore, the prediction of the electricity price has been an essential and very important task for all the agents involved in the pu...

Solar energy has become one of the most important sources of energy all around the world. Only in the European Union, between 2010 and 2019, solar photovoltaic (PV) electricity generation capacity increased from 1.9 to over 133 GW. Throughout this work, an economic analysis of the production of photovoltaic solar energy utility scale facilities is...
This paper presents a methodology to assess the cost of upgrading the LV network so that it can host increasing levels of PV distributed generation. The cost is valued in terms of investment, operation and maintenance and losses. A real scale case study (80,000 customers from urban and rural areas, 460 GWh of demand and 3,600 km of MV&LV lines/cabl...
The increasing penetration of renewable energy sources has presented profound challenges and opportunities to the power industry. The inherent variability and uncertainty associated with weather-dependent renewable sources have changed many aspects of power system control, operations and planning. The related electricity market operation and design...
In the last 150 years Andalusia has passed from being the most wealthy region of Spain to the poorest one, which has been compensated through territorial solidarity, which does not seem to be sustainable in the long term. On the other hand, the weakness of the industrial sector means that its levels of income, vulnerability and resilience are highe...
Abstract: Self-consumption of photovoltaic energy is being promoted as an effective way for energy consumption in residential households. The European Directive 944/2019 promotes the use of green energy and battery energy storage systems (BESS) for self-consumption and, in Spain, the 244/2019 Royal Decree of the Spanish electrical regulatory framew...
This chapter analyzes the business model of electric vehicle recharging.
As seen in previous chapters, the existence of a fast charging network is a success

The methodology evaluates the potential of the urban surface to accommodate thermal and PV solar facilities, as well as the energy storage requirements on a year-round basis....
Until now we focused our study on the economic profitability of a PV system and it turned out that the investment was worth it for the finances of its owner. The next question is to know if this investment is also profitable for the Earth. As PV is most of the time considered as a green energy, we are tempted to answer a great yes to that question...
Thanks to the literature review we have seen that grid parity is a phenomenon which had been widely studied by the scientific community during the last decade. Some affirms that it is already present in a large number of countries, others are more conservative and think it will take a few years more to be reached.

The next question is to know if this investment is also profitable for the Earth. As PV is most of the time considered as a green energy, we are tempted to answer a great yes to that question...
In this section we will carry out the study in other European countries so as to determine in which country grid parity is more likely to be reached. The first problem we faced is that the daily curve of the domestic electrical consumption is not publicly available in most of the countries. Consequently, we decided to limit our study to Mediterrane...
Until now, the profitability of a PV system was evaluated according to the common project indicators, the Net Present Value and the Internal Rate of Return. They give really useful information and they have the advantage of being simple to calculate and to interprete. In short, they are a very good first approximation of the project’s profitability...
Purpose
Spain has one of the greatest photovoltaic potentials in Europe. The boom suffered in the photovoltaic sector during the years 2007 and 2008 led to instability in the electrical system, prompting the legislator to develop a large number of legislative changes trying to control the electric system tariff deficit. These measures profoundly a...
This paper presents a practicable methodology allowing the impact of rooftop photovoltaic (PV) panels on distribution networks to be thoroughly assessed. Based on granular information (both in space and time) about the network and the demand, and a minimum but realistic set of assumptions concerning the available rooftop surface, hourly scenarios o...
The aim of this paper is to analyze the economic and environmental aspects of installing PV facilities for residential electricity users. This paper explores, in a conservative approach, the installation of a PV capacity to compensate the consumption with the production for each moment, never feeding electricity into the utility network and without...
The main objective of this paper is the application of big data analytics to a real case in the field of smart electric networks. Smart meters are not only elements to measure consumption, but they also constitute a network of millions of sensors in the electricity network. These sensors provide a huge amount of data that, once analyzed, can lead t...
