Nonetheless, the existing economic literature offers only partial explanations of why greater market integration is difficult to achieve in the real world despite its evident advantages in terms of overall welfare, supply security, and competitiveness. It is argued that power market coupling is an inherently political process involving significant institutional contestation and adaptation, and hence requires a more nuanced political analysis to be fully understood. This paper adds to the existing literature by conducting a comparative political economy analysis of electricity market coupling processes in Britain, Italy, and California, spanning from 2013 to 2021. It seeks to unpack how differences in the political economy contexts of these jurisdictions influenced the electricity market coupling process with their respective neighbouring systems. The analysis draws on 86 key policy documents, and 53 in-depth interviews with senior power system stakeholders in the three jurisdictions. Results widely align with claims in the political economy literature that market coupling outcomes do not simply reflect the most efficient solution. While all three jurisdictions have shown a commitment to enhance regional integration of short-term wholesale energy markets, there is considerable variation in policy outcomes, particularly the extent to which different segments of the market have been coupled. These differences can largely be attributed to variations in the political economy contexts of the three jurisdictions, including multi-level governance structures, diplomatic relations with neighbouring countries, and interactions with national political priorities and contexts. The main implications for the governance of electricity market coupling are discussed in the conclusion.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1040619024000654/pdfft?md5=291c4971dda58240b6ffdfbaf7a1c05e&pid=1-s2.0-S1040619024000654-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142084318","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":null,"pages":null},"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":null,"pages":null},"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 the last five years alone (2019–2023), more than 58 gigawatts (GW) of coal power capacity retired in the United States, while almost 30 percent of the remaining 194 GW of operating capacity is expected to retire by 2040. The cessation of operations at an existing power plant can have important impacts on the local economy, including job loss and a potential reduction in total economic output. Repurposing these assets effectively, including conversion into other power generation technologies, industrial manufacturing facilities, or commercial buildings, among others, can at least partially offset any negative economic impacts. This paper provides a review of ongoing and planned repurposing activities related to former coal power plants (not including repurposing related to fuel-switching from coal to natural gas) being pursued by utilities across the United States and discusses the costs, benefits, and challenges presented by types of repurposing assets or prospects.<span><span>²</span></span> The review shows that the repurposing type and capacity of the new projects is typically unrelated to the asset type and capacity being retired. The decision to repurpose a retiring power plant or unit is a result of a combination of factors that include, among others, decommissioning costs, land availability, and financial and regulatory incentives directed towards a clean and just energy transition. A list of current planned, in-process (under construction), or completed repurposing projects for energy and non-energy alternatives is presented, including several reference examples of repurposing from fuels other than coal.
