Performance-based regulation (PBR) combines increased efficiency incentives with explicit performance-achievement rewards. It is attracting both increasing academic attention and greater application in electricity regulation. The standard textbook approaches to the Capital Asset Pricing Model (CAPM) incorrectly describe the asset beta as simply a measure of risk. More correctly, it is a measure of risk per unit of expected return. This interpretation makes the use of the CAPM to determine allowed rates of return problematic. The incentives in Performance Based Regulation exacerbate this problem. Regulators who base part of their decision on \"judgement\" should rely more on that judgement and develop approaches that focus on regulatory, rather than market, outcomes.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"37 7","pages":"Article 107444"},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142658422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A decision-making model for empowering residential customers","authors":"Alejandro Parrado-Duque ,&nbsp;Nilson Henao ,&nbsp;Kodjo Agbossou ,&nbsp;Sousso Kelouwani ,&nbsp;Juan C.

Traditionally, upper-level agents, such as distribution system operators, aggregators, or coordinators, assume perpetual acceptance and participation by lower-level agents, like residential customers, in new demand-side programs. This assumption, alongside the presumption of agents’ benevolent behavior in a transactional environment, often overlooks the potential for false information in electricity markets, leading to significant economic losses and program failures. To address these challenges, we develop a transactive energy system based on mechanism design, structured around four comprehensive phases: Enrollment, Coordination, Execution, and Settlement. Customers adopt a decision-making model grounded in convex stochastic programming, enabling them to freely choose their daily enrollment in a demand response program and define their willingness to coordinate day-ahead electricity consumption once the Enrollment phase is cleared. The payment rule proposed in this work, which includes a penalty policy for energy deviations, ensures truthful information reporting from residential agents to the coordinator within a negotiation environment. Our results demonstrate that residential agents’ enrollment decisions vary according to the penalty values defined by the coordinator. Additionally, the number of customers enrolled in the Coordination phase significantly influences the coordinator’s daily profits. The study also highlights how electricity deviations during the Execution phase can increase customers’ costs beyond initial expectations, emphasizing the importance of adherence to planned consumption for optimal economic outcomes. This research offers a comprehensive transactive energy system that enhances customer participation through the principle of individual rationality and ensures truthful information reporting among agents based on the incentive compatibility concept in a day-ahead electricity market. Then, is it worthwhile to participate in transactive energy? The short answer is yes, and the reasons are unveiled throughout this paper.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"37 7","pages":"Article 107447"},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142707063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared to traditional topic modelling techniques based on word occurrence frequency, Bidirectional Encoder Representations from Transformers (BERT) demonstrates superior natural language processing results in generating contextual word and sentence vector representations by considering the semantic similarities of the text. Therefore, this study utilised this model to extract topics. From a total of 6218 patent data, this study extracted core topics and the main keywords for secondary battery technologies between 2013 and 2022 were lithium-ion, electric vehicles, unmanned air vehicles, and solar panels, confirming the accuracy of BERT-based patent analysis.

Urgent action is needed to improve LIHEAP to effectively address extreme heat and energy insecurity faced by low-income households and protect the health and well-being of disadvantaged groups spurred by climate change. In evaluating LIHEAP’s shortcomings, we demonstrate that there is a substantial gap between program eligibility and enrollment, such that many households are not receiving this vital benefit or do so mainly when facing a crisis. We also show that LIHEAP funds overwhelmingly support cold-weather states even as record-breaking heat is a critical stressor. The spatial mismatch we unveil shows that southern states receive less LIHEAP funds despite higher cooling degree days and higher rates of energy insecurity. The importance of swift action based on sound data and up-to-date research can enhance the efficacy of LIHEAP, expand its reach, and ultimately improve the living conditions of millions of energy insecure households. We offer several recommendations to improve LIHEAP to ensure that this critical lifeline program remains an effective tool to mitigate energy insecurity and safeguard livelihoods in the face of extreme heat.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"37 7","pages":"Article 107440"},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142310866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Utilising interviews and questionnaires, resilience parameters were obtained. Twenty resilience indicators were identified from established and documented research and were categorised into five distinct capacities: preventive and mitigative, anticipative, absorptive, adaptive, and transformative. This approach addresses a significant gap in the literature on organisational resilience, which often focuses predominantly on adaptive capacity. Our analysis compared resilience strengths and weaknesses, revealing a predominance of the latter, with financial constraint identified as a universal challenge across all capacities. Particularly, the transformative capacity exhibited the largest gaps between strengths and weaknesses, underscoring the operator's challenges in responding to severe disruptions. The findings suggest that resilience in the context of Malawi's power grid operator extends beyond operational capabilities, highlighting the critical importance of robust infrastructure to enhance the overall resilience framework. This work offers practical insights for policymakers and infrastructure managers, particularly in developing countries facing similar challenges. It calls for a strategic realignment towards bolstering transformative capacity and securing financial resources, enhancing critical infrastructure resilience, and underlining these proposed actions' urgency and importance.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"37 7","pages":"Article 107427"},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1040619024000629/pdfft?md5=53e317d27361b840de2787cf4eb7a54c&pid=1-s2.0-S1040619024000629-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142058057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose a continuous participation and feedback approach to system equity improvements and evaluation that incorporates engagement in planning and decision making processes as an integrated cycle. We provide example methods for increasing participation, developing structures and processes to receive and incorporate feedback, and measuring outcomes. Equity outcomes are particularly difficult to measure due to the impact of other socioeconomic and historic conditions, as well as the qualitative nature of experiences of inequity. To identify a set of equity outcomes that can be impacted by increased participation, we examine the relationship between regulators, utilities, and the community, and propose that folding engagement and continuous feedback into the normal functions of these organizations can improve the outcomes for energy system users.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"37 7","pages":"Article 107442"},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142552868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the Vector Error Correction model, this study investigates whether electricity consumption from the domestic and commercial sectors has an impact on biocapacity deficit. The result shows that, in the long run, domestic electricity consumption is not significant in causing biocapacity deficit, whereas commercial electricity consumption has an increasing effect on the latter, making it unsustainable. Further, lower levels of income and natural resource rents are also observed to lead to biocapacity deficit. In the short run, however, neither domestic nor commercial consumption has any significant impact on biocapacity deficit. The findings call for an extended focus on the sustainable management of electricity consumption across sectors so that their adverse impact on biocapacity can be minimised.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"37 7","pages":"Article 107443"},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142571649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
