Special Issue Information

Dear Colleagues,

Sulphur dioxides, nitrogen dioxides, and carbon emissions released due to the combustion of fossil fuels have led to significant environmental issues worldwide. The transformation of the energy structure has been considered an effective means to cope with the increasing environmental pressure, mitigate climate change, and meet the climate-related Sustainable Development Goals set by the United Nations. Reducing fossil fuel consumption and incentivizing renewable power development are frequently employed in recent years, which offer the benefit of improving the environmental efficiency of the power system without damaging the economy.

However, the rapid development of renewable power often faces grid availability issues. The diversity in fuel structure, technological level, and the competition for limited emission quota also highlight the importance of balancing the development of different generation forms. In the perspective of environmental efficiency, various models and methods may lead to totally different results; data envelopment analysis (DEA) and stochastic frontier analysis (SFA) are among the most frequently used techniques in benchmarking environmental efficiency. All these studies reached the same verdict that efficiency improvement is not only limited to technology but also social welfare and resource allocation, policy formulation, and economic development patterns. In academic research, environmental efficiency evaluation is heavily dependent on the study’s objective, input and output variables, and methodology selection.

Due to the importance of this topic, this Special Issue of Energies on “Environmental Efficiency Evaluation of Power Systems” aims to explore the economic feasibility of low-carbon transformation and high-quality development of power systems.

The call for papers seeks to collect several empirical, theoretical, or case studies with practical policy implications on the environmental efficiency evaluation of power systems.

The studies need to provide practical policy solutions for decision makers to effectively formulate medium- and long-term development strategies in response to climate change. These solutions should be multiobjective in nature and focus on the high-quality development and low-carbon transformation of power systems. Papers may deal with, but not be limited to, the following:

  • Nexus of economy, technology, and environmental efficiency target achievement;
  • Generation, transmission, distribution companies or power system efficiency;
  • Improving the energy and environmental efficiency of power systems;
  • Distributed generation of electricity and its environmental impacts;
  • Efficiency evaluation based on environmental heterogeneity;
  • Total factor productivity and its decompositions;
  • Ways to increase green total factor productivity;
  • Solutions regarding the green energy transition in the post-COVID-19 era;
  • Role of sustainable and green finance in power system efficiency;
  • Spatial characteristics of environmental efficiency;
  • Evaluation of economic, political, technological, or environmental policies that may affect the efficiency of the power system;
  • The impact of renewable energy development on efficiency.

Electricity sector reforms have transformed the structure and organization of the sector worldwide. While outcomes of reforms in developed and developing countries have been extensively examined, there is limited analysis of the reforms in sub-Saharan Africa (SSA). This paper analyses the performance of electricity sector reforms in 37 SSA countries between 2000 and 2017. We use a stochastic frontier analysis approach to estimate a multi-input multi-output distance function to assess the impact of reform steps and institutional features on indicators of investment and technical efficiency. Results indicate a positive correlation between reforms and installed generation capacity per capita, plant load factor, and technical network losses. The presence of an electricity law, sector regulator, vertical unbundling, and private participation in the management of assets were positively correlated with reform performance. Perceptions of non-violent institutional features such as corruption, regulatory quality and governance effectiveness do not seem to have had a significant effect, but perceptions of political stability, violence, and terrorism influenced reform outcomes. We conclude that a workable reform in SSA involves vertical unbundling with an electricity law, a regulator, and private ownership and management of assets where feasible. However, positive outcomes go hand in hand with higher technical network energy losses which indicates higher investment in the generation segment than in the network segment. Hence, emphasis should be placed on decoupling the energy losses from power generation. Full article

Transmission and distribution networks are capital intensive segments of the electricity sector and are generally considered natural monopolies. Due to their non-competitive nature, these are subject to independent regulation to prevent the abuse of monopolistic power and to induce competitive behaviour. Effective economic regulation of the electricity networks has become a key target in most developed economies after the 1980s. In Norway, incentive regulation and efficiency benchmarking were introduced in 1997. In Norway, the electricity grid is divided into three levels, namely, central, regional and distribution networks. In this paper, we study two overlooked aspects when analysing the performance of electricity networks: vertical integration and ownership structure. We use a stochastic frontier analysis approach to analyse the performance of Norwegian electricity distribution utilities for the period 2007–2014. We observe that vertical integration between distribution and regional transmission implies higher cost inefficiencies. This indicates that the efficiency gains due to separate management of the networks exceed the economies of coordination from vertical economies of scope. In addition, we find that council ownership entails higher efficiencies. This could be explained by the state having an interest in high-voltage electricity networks, rather than low-voltage ones, and the decentralised model from which the now centralised system was once developed.

This research presents the energy, exergy, economic, and environmental assessment, and multi-objective optimization of a flash-binary geothermal CCHP cycle. A sensitivity analysis of production well inlet temperature and cooling to power flow ratio on exergetic, economic, and environmental parameters was conducted. Furthermore, the effects of the inflation rate and plant working hours on economic parameters were investigated. Results showed that increasing the production well inlet temperature harms exergy efficiency and exergetic performance criteria and results in a gain in exergo-environmental impact index and heating capacity. In addition, the total plant cost increased by raising the production well temperature. Furthermore, increasing the cooling to power flow ratio caused a reduction in exergy efficiency, exergetic performance criteria, and produced net power and an enhancement in exergy destruction, cooling capacity, and total plant cost. The exergy efficiency and total cost rate in the base case were 58% and 0.1764, respectively. Optimization results showed that at the selected optimum point, exergy efficiency was 4.5% higher, and the total cost rate was 10.3% lower than the base case. Levelized cost of energy and the pay-back period at the optimum point was obtained as 6.22 c$/kWh, 3.43 years, which were 5.14% and 6.7% lower than the base case. Full article
