The energy transition is driving a significant transformation in the electricity sector, with a focus on demand-side engagement. Using the VAR-VEC model methodology, we explore hourly consumer responsiveness to electricity prices for two distinct consumer groups differentiated by their pricing schemes within the Spanish retail market. The research...

The integration of renewable generation sources into wholesale electricity markets is expected to reduce day-ahead marginal prices. This effect has been widely evidenced by previous literature and is commonly referred to as the merit order effect. However, the factors influencing the components of final prices, other than the day-ahead market price...

Given the existence of different databases from different sources that offer information on forward electricity prices, the need to compare them arises to guarantee that research results and trading decisions based on them are not sensitive to the database used. We worked with forward electricity prices traded over the counter, closest month to mat...

Optimal futures hedging positions for those agents trying to maximize their expected utility will depend on their view about the evolution of the market and on how risk adverse they are. The most risk adverse agents will probably decide to full-cover their positions. But when a futures bias exists, hedgers with moderate or low degree of risk aversi...

We investigate the extent and evolution of the links between energy markets using a broad data set consisting of a total of 17 series of prices for commodities such as electricity, natural gas, coal, oil and carbon. The results shed light on a number of relevant issues such as the volatility spillover effect in energy markets (within and across sec...

The relationship between electricity prices and fuel costs has been extensively studied. Many studies have analyzed the relationship between electricity and natural gas prices and found that electricity and natural gas futures prices are cointegrated. In this paper, using different factor models to jointly estimate the dynamics of both commodities,...

The change in the generation mix from conventional electricity sources to renewables has important implications for bidding behaviour and may have an impact on prices. The main goal of this work is to discover the role played by expected wind production, together with other relevant factors, in explaining the day-ahead market price through a data p...

This paper analyses the relationships between prices from three different markets within the Spanish zone of the Iberian Electricity Market (MIBEL), namely futures, spot and over the counter (OTC) forward markets. The study focuses on three items: (i) contrasting the Weak-form efficiency hypothesis of the markets involved in the study, (ii) analysi...

Many countries around the world have increased their renewable installed capacity due to a greater awareness of climate concerns. Under this new framework, with renewables being among the main generation sources, the literature warns of a dramatic change in price behaviour. Some of the most commonly claimed effects of having a significant proportio...

Although stock prices fluctuate, the variations are relatively small and are frequently assumed to be normally distributed on a large time scale. But sometimes these fluctuations can become determinant, especially when unforeseen large drops in asset prices are observed that could result in huge losses or even in market crashes. The evidence shows...

This paper examines the influence of Spanish major political events on stock market performance by testing the empirical implications of the existing theories focused on the connection between politics and stock exchanges. On the one hand, our findings give support to the partisan politics theory, since stock returns behave differently depending on...

Statistical analyses regarding climate studies have often used the average temperature as one of the main variables. However, the tails of the respective distributions are also crucial and have become increasingly considered in recent years. As the Intergovernmental Panel on Climate Change in its fourth assessment report (IPCC 2007) states, “the ty...

The Spanish electricity intraday market presents a particular design that makes it unique in Europe. The study is carried out on an hourly basis in order to identify hourly patterns in prices and traded quantities by session. The study evidences an overall growing interest from market participants in intraday trading, particularly in the last-time-...

This study carries out a comparative analysis of the two Spanish spot electricitymarkets: the day-ahead market and the intraday market. Due to the features of electricity,it is very important to program electricity generation in advance. The Spanish electricitymarket includes a peculiar intraday market in which agents can trade their electricity af...

The purpose of this study is to investigate the causal linkages between the Spanish electricity, Brent crude oil and Zeebrugge (Belgium) natural gas 1-month-ahead forward prices. Following Lütkepohl et al. (2004), we control for the presence of a structural change in the series and then we use the Johansen cointegration test and a vector error corr...

Deregulation in energy markets has entailed important changes in the way agents conduct business. Price risk arises as a result of fluctuations in the future price of electricity and agents assume long or short positions in the forward and spot markets to hedge their exposure to price risk. The presence of forward risk premium in prices is evidence...

This paper examines the influence of Spanish major political events on the stock market performance. The analytical results demonstrate that there are no systematic differences in excess returns in the last two years preceding an election, that market responses are of the same magnitude when incumbents win or lose the election, and that there is no...

This paper analyses the economic incentives embodied in the rules governing the resolution of transmission constraints in the Spanish wholesale electricity market and the way these incentives may have influenced on the trading behaviour of both the generators and the demand side. The evidence obtained is consistent with them responding to these inc...

This paper carries out a comparative analysis between the Spanish day-ahead market and the intraday market. Due to electricity's features, it is very important to program generation electricity in advance. The Spanish electricity market includes a peculiar intraday market in which agents can trade their electricity after the day-ahead market closes...

The theory of cost-of-carry cannot be applied to an asset like electricity because power is not storable. An alternative approach to price forward contracts is given by equilibrium models. We conduct an empirical analysis of the forward risk premium in electricity forward prices, obtaining support for the implications derived from the Bessembinder...

This paper empirically investigates how the economic incentives embodied in the rules governing the resolution of transmission constraints in the Spanish wholesale electricity market have influenced the trading strategies spanning all the sections of the market followed by buyers and sellers. The results show several facts with far reaching consequ...
