“…Several authors have worked in this industry green-renewal process. Figueiredo et al [ 37 ] explain the issues around replacing traditional coal-based power plants with photovoltaics, while Pereira and Saraiva [ 38 ] explain the implications of the penetration of wind power, since this process is putting the profitability of traditional stations under pressure. Distributional costs of wind energy production in Portugal under the liberalized Iberian market regime can be found in Prata et al [ 39 ].…”

Slow economic recovery, market concentration, and scant alternative energy sources make the Iberian energy market quite idiosyncratic when compared to the rest of the EU. This paper focusses on the Iberian energy market by dealing with the analysis of the relationship between energy consumption and energy prices by using fractional integration in the Iberian market. This technique is used in order to examine the degree of persistence of the series, looking at the spot and futures markets in Spain and Portugal. The results indicate that all the series are fractionally integrated, showing long memory and mean reverting behaviour. Moreover, a close relation between energy consumption and energy prices is found in the spot market whereas it is not found in the futures market. In fact, there is a weak relationship between the futures market and energy consumption. However, regarding energy pricing, the relationship is stronger but with the spot market itself.

“…Previous studies made useful attempts from technical and social perspective. Figueiredo et al [20] explored the impact of replacing coal-fired generation by photovoltaics from the Portuguese electricity system. The authors studied three scenarios and provided the deployed PV capacity correspondingly.…”

This paper analyzes if solar photovoltaic technology is economically feasible enough to compete with coal-fired power in Chinese cities in the subsidy-free context. Considering this, this paper further investigates how profitable investing in solar PV projects is. This paper firstly analyzes to what degree local coal-fired power plants can be replaced by distributed solar power in 344 prefectural-level cities in China. Levelized Cost of Electricity of solar PV power and the local desulfurized coal benchmark price are used for simplified cost crossover math to identify the replacement risk of local coal-fired power plants. Four risk-levels and their corresponding cities are identified, i.e. deemed no cost-risk, potentially at cost-risk, at cost-risk, and substantially at cost-risk. As a whole, 85.17% of current coal-fired power plants from the investigated cities are under cost-risk. Levelized Profit of Electricity, Net Present Value, Internal Rate of Return, and Discounted Payback Period are calculated for each city, and grouped using K-means algorithm. The cities are clustered into four groups, i.e. high return, medium return, moderate return, and low return. The results show that 65.99% of all the cities could achieve a moderate or higher financial return. The cost-risk and investment profit results are mapped for a better understanding of the regional variation in China.

“…Several authors have recently investigated the Spanish market and its peculiarities. In terms of the green renewal process R. Figueiredo et al (2019) studied the replacement of traditional coal-based power plants with photovoltaics, while Pereira and Saraiva (2013) explained the implications of the penetration of wind power. Ciarreta and Zarraga (2010) studied the dynamic relation between electric consumption and the gross domestic product, and, more recently, Ciarreta and Zarraga (2016) examined the volatility of the intra-day electricity market.…”

We examine the hourly structure of energy prices in Spain using 12 one-month-long series (from November 2020 to October 2021) of samples of hourly pricing (from 00:00 to 23:00) for each day of the month and applying a long memory approach with fractional integration analysis. Our results indicate that the series are highly persistent, with shocks having permanent effects with non–mean reversion properties, with no month-specific effects on the data series.
