  • The Convoluted Path of Power Sector Reforms Underutilized Generation Capacity A New Challenge for Indian Thermal Power Generators   Order a copy of this article
    by Brijesh Bhatt, A.K. Tripathi, G.C. Tripathi 
    Abstract: India embarked upon the path of power sector reforms in 1991. With subsequent steps like opening up of private investment in generation, unbundling, open access, power trading and many other structural & policy initiatives for generation, transmission and distribution, it aimed to promote competition in the sector. In a country facing chronic power shortages, one of the key objectives of these reform initiatives has been to ensure an optimal investment in generation capacity as well as optimal capacity utilization for the generation sector. Against this backdrop, we studied the evolution of generation capacity in the country, with focus on three aspects, namely, fuel-source wise, ownership wise, and region wise capacity addition. We also analyzed how effectively the capacities are being utilized. The analysis revealed two significant results: (1) there is considerable stranded capacity which does not get through to the grid and (2) there is also significant capacity which is grid connected and commercially available, but is producing at very low plant load factor (PLF). In a country which faces power deficit, such a situation is a matter of great concern. To ensure sustainable energy supply system, these issues need to be addressed through appropriate interventions.

  • Crude oil futures tail risk measurement based on extreme value theory   Order a copy of this article
    by Chunjiao Gao 
    Abstract: In this paper, VaR, ES and spectral risk (SR) measures of tail risk are calculated based on extreme value theory. The empirical results show that the extreme value POT model can be used to characterize the tail risk of earnings under extreme fluctuations in Brent crude oil futures prices. Moreover, the risk of VaR, ES and SR at the tail of Brent crude oil futures based on extreme value theory is higher than that under the normal distribution assumption, which indicates that the traditional normal distribution assumption will underestimate the tail risk.
    Keywords: Spectral risk measurement; hyperbolic risk spectral function; extreme value theory; tail risk.

  • Research on the energy-saving effect evaluation of open-pit coal mines based on energy audit   Order a copy of this article
    by You ZHOU, Yu Liu, Yuan Li 
    Abstract: Energy conservation is a long-term strategic policy of China's economic development, and the issue of energy resources has become a strategic issue in countrys economic development. At present, the management level of open-pit coal mine is relatively low, and energy audit is less carried out, energy audit provides data analysis, benchmarking management, technical reform suggestions and other contents for the current energy consumption of enterprises, which can increase the energy management of enterprises and reduce energy waste. This study takes the open-pit coal mine as an example, the research shows that energy consumption in the transportation process of an open-pit mine is the highest, most of which comes from diesel oil. Optimizing truck transportation routes and reducing truck waiting time are the most important ways to save energy in open-pit mines. The highest are the annual transportation volume of trucks, the lowest the annual average diesel fuel consumption. The energy consumption monitoring of large electric shovels is necessary. Electric-driven mining and stripping equipment can replace oil with electricity and reduce energy consumption.
    Keywords: Open pit coal mine; energy audit; energy saving evaluation; energy saving effect evaluation.

  • Do oil prices predict the dynamics of equity market? Fresh evidence from DCC, ADCC and Go-GARCH models   Order a copy of this article
    by Fatma KHALIFA, Abderrazak DHAOUI, Mohamed Sahbi NAKHLI, Saad BOUROUIS, Saloua BENAMMOU 
    Abstract: This paper investigates the dynamic condition correlations between oil price, industrial production, short-term interest rates and equity market in South Korea using three types of GARCH models. The results from the DCC and ADCC GARCH models show strong evidence of significant dynamic conditional correlations suggesting higher long-term persistence of volatility than short-term persistence. The findings suggest, particularly, that oil prices have positive dynamic conditional correlations to equity markets, while the dynamic conditional correlations between equity market and short-term interest rates are significantly negative. These results have considerable economic implications. Firstly, oil price as a risk factor increases the equity market volatility. It also represents an implicit risk factor that cannot be diversified and which requires therefore to be hedged or priced. Secondly, the oil acts as an inflationary factor leading central banks to adjust their short-term interest rates in order to smooth the inflationary effect on both real economy and financial activity.
    Keywords: oil price; equity market; industrial production; short-term interest rates; dynamic conditional correlations.

  • Covid-19 and oil price shocks: the case of Republic of the Congo   Order a copy of this article
    by Ilyes Abid, Amine Ben Amar, Khaled Guesmi, Thomas Porcher 
    Abstract: The downturn in the global economy following the outbreak of COVID-19 pandemic has caused a fall in demand and a huge decline in oil prices. To examine the impact of negative exogenous shocks including oil price shocks, most studies focus on how it impacts on a country's economic growth. Focusing on the Republic of the Congo, our paper incorporates the modalities of sharing oil rents between the State and the oil exploration companies. In particular, our analysis is based on the rent sharing modalities of the fifteen oil contracts in this country. We demonstrate that the Republic of the Congo suffers three shocks: declining oil price shocks, diminishing share of oil rents with the exploration companies and a reduction in production volumes. Our work offers a better assessment of the needs of the country and the necessary aid that may promote stability and a reduction in the risk of a food crisis.
    Keywords: oil resources; economic development; Africa; Congo; COVID-19.

  • Intelligent control of Heavy Media Separation   Order a copy of this article
    by Wenbao Lv, Chuanzhen Wang 
    Abstract: The shortcomings of the density control system for heavy media suspension in the current coal preparation plant were introduced. The intelligent control system of heavy media separation suitable for different coal quality characteristics in LinHuan Coal Preparation Plant was proposed. The system was mainly composed of the following parts: relationship between ash and mineral content, automatic identification of raw coal production source information, automatic adjustment of online ash analyzer parameters, closed loop control system based on clean coal ash content. After intelligent control of heavy media separation was applied. The processed raw coal production source information and ratio could be automatically identified by the system, and the parameters of the online ash meter could be automatically adjusted. The clean coal ash content after heavy media separating was relatively stable, and the product qualification rate was improved.
    Keywords: raw coal; clean coal; separation; heavy media; ash content.

  • The effect of government expenditure on energy intensity: a panel smooth transition regression (PSTR) approach   Order a copy of this article
    by Mohammad Movahedi, Kiumars Shahbazi, Samad Hekmati Farid 
    Abstract: Energy is a major factor of sustainable development, and governments are faced with some challenges such as the expenses involved in running the economy and how to carry out such expenses in order to reduce energy intensity and provide energy efficiency. This article investigates the effect of government expenditure on energy intensity on the Top 10 European crude oil exporting countries, during 1995-2014. The results confirm the nonlinear effect of government expenditure per GDP on energy intensity, with one threshold parameter. The findings indicate that the effect of government expenditure per GDP on energy intensity is significantly negative at low government expenditure (at first regime) and positive at high government expenditure (at second regime). The positive and increasing effect of government expenditure on energy sector in the second regime reveals that the government intervention at macro programs and high government size has the potential to hike up energy intensity.
    Keywords: government expenditure per GDP; energy intensity; PSTR; European crude oil-exporting countries.

  • Contributions of bioethics towards a new paradigm of energy   Order a copy of this article
    by Carlos Díaz-Rodríguez, Abdénago Yate-Arévalo, Mónica Bustamante-Salamanca 
    Abstract: Adequate access to energy services contribute to economic development, overcoming poverty, and improving quality of life. The generation and use of energy based on fossil fuels are some of the main causes of anthropogenic pollution. The objective is to develop an energy paradigm with a bioethical perspective that supports technical and economic approaches and allows the transition to a low-carbon energy regime. Etymologically, 'energy ethics' and 'ethics of energy' are addressed, from a theoretical-practical literature review on energy. The traditional energy paradigm discussed in this research is based on energy principles and values that reduce natural and human processes to energy conversions achieved through scientific control of the forces of nature. A new energy paradigm is proposed based on bioethical aspects such as the precautionary principle, justice as equity, protection and the principle of responsibility, which allows the management of the nature of problems in the energetic sector.
    Keywords: energy ethics; ethics of energy; energy paradigm; bioethics.
