Analysis Platform

This paper analyses the impacts of electricity generation from solar energy on the Thai electricity industry. In this paper, three scenarios (REF, Solar2015 and Solar2018) are developed to represent an increased levels of electricity produced from solar energy. A Low Emissions Analysis Platform (LEAP) model is employed, in this paper, to assess the impacts for the period 2019–2037.This paper assesses and analyses the scenario impacts in terms of diversification of electricity generation, fossil fuel requirement and emissions of CO2 and SO2. The analysis reveals that increased electricity generation from solar energy would help diversify energy supply for electricity generation, reduce fossil fuel imports, and therefore help improve energy security of the country. Furthermore, it would help mitigating CO2 and SO2 emissions – an issue of environmental significance. Despite several benefits, there are a number of emerging barriers for promoting electricity generation from solar energy in Thailand. These include the intermittency of solar energy, high-capital cost, unsupportable grid infrastructure and unfavourable regulatory framework. This paper, therefore, suggests that the implementation of energy storage system, provision of financial incentives to potential investors, improvement of grid flexibility and the revision of the regulations to support solar energy business could be effective strategies in order to address the barriers facing the Thai electricity industry.

The Russian energy industry is on the verge of major changes. The potential of existing technologies has been exhausted, and to ensure economic growth, the development and implementation of new approaches in the field of electricity generation is necessary. The human capital of enterprises is the most important driver of changes in the energy sector. The purpose of the article is to analyze the influence of factors characterizing human capital on the effectiveness of Russian power generating corporations. The study found that the efficiency of power generating corporations is most strongly influenced by the share of managers in the structure of employment and labor productivity. Such indicators as the share of specialists with higher education and staff turnover did not significantly affect the efficiency of power generating corporations.

Abstract In view of the growing importance of distributed generation, the pluralization of the energy matrix close to large consumption centers has become necessary. In this sense, the energy sector can contribute to electricity generation using waste products such as vinasse, the most relevant in terms of volume and polluting capacity. The general objective of this article is to analyze the economic feasibility of using vinasse for electricity generation, and as a specific objective, to identify the viable price range of MWh in free and regulated energy environments and the productive capacity of plants for this type of investment. The methodology used was quantitative research, based on the cost structure of a biodigester IC internal combustion engine with 38% yield and vinasse logistics according to the production capacity of autonomous plants of 100 m3, 1,000 m3, and 3,000 m3ethanol/day for scenarios with and without tax exemptions for a price range between US$ 26.04 and US$ 130.20/MWh. The analysis shows that the use of vinasse for electricity generation is restricted to medium and large producers. Furthermore, the price of MWh is more relevant than the tax exemption for the feasibility of this type of project. This corroborates the constant requests from the sugar-energy sector to hold exclusive electricity auctions for biomass, given its cost structure and its social, economic, and environmental externalities.

Recent research has increasingly interrogated the association between oil and civil conflicts within the political context while overlooking the primary use of oil. This paper examines three aspects of the claim “oil is a curse”. First, is it true? Second, is there a link between oil and civil conflicts? And third, do higher oil prices affect the energy sector, specifically electricity generation and pricing? By employing correlation matrices with data spanning from 1970 to 2016 at both global and local scale, the results of this analysis indicate that oil may be a curse or a blessing. Observation of oil prices and civil conflicts suggest a relationship between higher oil prices and severe civil conflicts with foreign state intervention. Severe imperial/colonial conflicts are associated with lower oil prices while no relationship is observed between oil prices and state based civil conflicts. These findings demonstrate that civil conflicts can arise in cases when oil prices are low and that foreign states have a bearing on oil related conflicts. Both electricity generation from conventional thermal sources and the fuel cost charge component of electricity prices are highly affected by global oil prices with correlations of 0.54 and 0.74, respectively. Renewable electricity sources - hydropower and geothermal were unaffected by global oil prices. This study does not endorse the use of conventional thermal sources for electricity generation while inviting more in-depth case studies on the link between civil conflicts and oil price shocks and their effects on the energy sector.
