Governments, utilities, planners, and the research community are working to advance a more nuanced understanding of energy equity, involving distributive, procedural, recognitional, and restorative aspects. Complete energy equity requires a holistic understanding of all these aspects, and energy planning should attempt to address them simultaneously. In practice, this can be challenging in contexts where the available pool of human and economic resources is limited. This article presents a case study of a community within the Navajo Nation to illustrate the challenges and implications in such contexts. The first challenge is the inevitable prioritization and compartmentalization of decision making due to the constraints imposed by the planners’ primary mandates, authority, place-based contextual factors, and available resources. The second – related – challenge is the impact of the resulting decisions on realized outcomes, and its effects on the community perceptions of – and confidence in – the planning institutions. The case study also finds that equity concerns of the utility’s end-customers may not always be uniform and are influenced by the customers’ perspectives, roles, responsibilities, and expectations. Thus, a more holistic view of energy planning is necessary to 1) capture the variations of equity opinions and priorities across all stakeholders, 2) to ensure that decisions and resource allocations by utilities, elected bodies, or governmental agencies occur on multiple fronts in a coordinated and transparent manner to advance energy equity targets.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"38 1","pages":"Article 107456"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143151178","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}

Despite nearly two decades of evolution, however, transmission planning processes in the United States rarely consider storage alternatives and only a handful of projects have been selected. Regulators have assigned the responsibility of proposing non-transmission alternatives to non-utility participants in the planning process, so the sparse record of SATA projects may therefore result from a lack of specificity about the use cases for SATA and uncertainty about when it should be proposed. Extensive literature has been devoted to the topic of SATA, but much of it relies on definitions that are inconsistent with regulatory precedent and that exacerbate confusion. This paper reviews regulatory proceedings to define three types of energy storage assets than can interact with the transmission system: storage <u>as</u> a transmission asset, storage <u>in place of</u> a transmission asset (SIPTA), and <u>dual-use</u> energy storage. It then provides an inventory of use cases for SATA and SIPTA projects, using brief case studies to illustrate each use case. By clarifying the definition of SATA and its roles in transmission system planning, this work may be of use to transmission system planners and other participants in transmission planning processes to identify situations in which SATA alternatives merit consideration.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"37 7","pages":"Article 107441"},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142552867","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}

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":"37 7","pages":"Article 107430"},"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}

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}
