Sensitivity analyses are performed for 19 cities, varying the renewable fraction from 0% to 100%, to determine the minimum renewable energy fraction required to achieve competitive Cost of Energy (COE) values. The results show that increasing the renewable fraction reduces the COE of PV systems but leads to higher capital costs and Net Present Cost (NPC).

The outcomes provide valuable insights for decision-making and promote sustainable energy transition in KSA. Grid-connected PV systems bring social benefits, including job creation, improved living conditions, reduced emissions, enhanced energy security, and increased public awareness.

Researchers have not reached a consensus about defining and measuring energy poverty, leading to ineffective energy-related policy formulation. Existing approaches simplify energy poverty to a \"yes-no\" approach, neglecting its multidimensional nature. The subjective parameters and thresholds used further introduce uncertainty and bias. We addressed this gap by formulating a comprehensive Residential Energy Poverty Index (REPI) for Indian states by adopting a multidimensional approach, including clean and green energy, energy efficiency, accessibility and reliability, and appliances. The current approach focuses on energy availability beyond basic needs and should look at the broader dimensions of quality of life, socioeconomic well-being, education, and environmental sustainability. The work is based on the Indian residential energy survey conducted by CEEW, which included 14,850 households across 21 Indian states. REPI was constructed by assigning weightage to different variables across four dimensions using Principal Component Analysis. Multiple Linear Regression was utilized to identify the socioeconomic factors impacting REPI.</div><div>Findings reveal that enhancing energy efficiency and decentralized solar power, particularly in states like Chhattisgarh and Jharkhand, can significantly improve energy access and reliability.

The findings highlight the importance of tailored state-specific policies like decentralized renewable energy, energy cleanliness and awareness campaigns to address residential energy poverty in India.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"93 ","pages":"Article 101878"},"PeriodicalIF":3.8,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143099143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A determining factor to stimulate this type of investment is the rate of return approved by the regulatory commissions. The return expected by investors (cost of equity) depends on the risks associated with these investments. Regulatory commissions commonly use the Capital Asset Pricing Model (CAPM), for which only market risk is relevant. Market risk is low for regulated firms, ignoring other risk types, and is measured with firms and variables outside the Latin American region. This procedure, however, does not consider the risks these types of investments are exposed to in Latin America. In this analysis, six risk factors were initially proposed to explain the risk-return relationship of these types of investments; nevertheless, after an exploratory analysis of the factors, two factors were eliminated to form a four-factor model (Electric-4). Then, the CAPM model was contrasted with the Electric-4 model. Both models used Latin American firms and market variables, and both were evaluated between July 2010 and July 2022. The analysis sample comprises 28 electric utilities dedicated to transmission and distribution. Through regression analysis, we found that the Electric-4 model explains a higher percentage of the variations in the portfolio returns of electric utilities in the Latin American Integrated Market (MILA), São Paulo Stock Exchange (BM&F), and Buenos Aires Stock Exchange (BCBA). These results help to understand the risk-return relationship of electric power infrastructure investments in the Americas for investment decision-making. In addition, the proposed model aids the regulatory commissions in Latin America in establishing an adequate return on equity cost of capital that encourages investments in electric power infrastructure.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"93 ","pages":"Article 101812"},"PeriodicalIF":3.8,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143164056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several methodologies, including the Logarithmic Mean Divisia Index (LMDI) decomposition, Tapio decoupling analysis, and the decoupling effort method, have been employed to analyze energy-related carbon dioxide emissions. These approaches have been applied across various time frames: single-period, year-by-year, and multi-period analyses. However, previous studies have often overlooked significant trend changes in the indicators. This study introduces a methodology that integrates decomposition and decoupling analysis within a multi-period time frame, explicitly accounting for major trend shifts in the carbon dioxide time series. The time frame is defined using a total mean squared error (TMSE) minimization approach. The decomposition analysis employs the additive LMDI method, while the decoupling analysis utilizes the Tapio and decoupling effort models. A case study of Portugal’s carbon dioxide emissions from 1995 to 2020, disaggregated into six energy-consuming sectors, demonstrates the effectiveness of this methodology. The results highlight the substantial impact of carbon intensity, particularly in the electricity and heat sectors. This study demonstrates that accounting for trend changes in period selection provides critical insights, enabling a more thorough and accurate analysis of carbon dioxide emissions.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"93 ","pages":"Article 101863"},"PeriodicalIF":3.8,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143099139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
