Nearly 7000 coal mines collectively produce over 8.5 billion tons of coal every year. Over 2400 coal-fired power plants across the globe operate with a capacity of 2175 gigawatts. Then, there are numerous rail networks, trucks, and port terminals that constitute parts of the coal value chain. Yet in a net-zero world, this value chain will need to shrink rapidly, which could negatively impact the economies and communities that currently depend on it. Scholars and practitioners believe that repurposing elements of the coal value chain for other uses – such as using repurposed coal mines for solar – could be an innovative way to boost the overall energy transition and facilitate a just transition for local communities. However, prior studies and real-world practice has focused on repurposing individual assets such as individual coal power plants. Despite the global scale of coal infrastructure abandonment and apparent opportunities for repurposing whole value chains, no studies provide a comprehensive understanding of the state of knowledge about coal sector repurposing in major coal dependent economies. Moreover, prior work does not take a comprehensive “systems-level” approach to repurposing. We fill these gaps. We construct three comparative case studies – focusing on South Africa, India, and the US – to describe the current state of repurposing efforts in each country and explore the potential for systems-level repurposing. We define systems-level repurposing as the transformation of two or more components of the coal value chain into new interlinked industrial applications. We collected data for the case studies through a literature review, field visits to coal-dependent areas, 42 interviews, and a workshop involving experts and key stakeholders. We find that different countries are at different stages of repurposing research, planning and implementation. Coal mines and power plants have been the primary focus of repurposing efforts to date, while transport networks (apart from the US) and export/import terminals remain largely overlooked. In addition, neither research nor policy action takes a systems-level approach to repurposing. We identify three promising pathways for systems-level repurposing: alternative energy, overburden to sand, and agriculture. Overall, our work highlights the need for more holistic, value chain-level repurposing planning to support a just energy transition.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"39 2","pages":"Article 107527"},"PeriodicalIF":2.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146001778","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}

However, there is a lack of knowledge about how different segments of the population want to participate in energy policies. Through a national survey we investigate how different segments of the Dutch population want to participate in local and national energy transition decision-making. We identify that citizens make decision in terms of their expected gains of participating and how much time they want to invest in participation. Some citizens only want to invest a little amount of time and as a consequence these citizens will only participate in processes with a low time investment. Second, we observe a climate concern paradox where individuals concerned about climate change often refrain from participating in formal processes due to distrust in government and perceived tokenism, preferring activism instead. Our results highlight the need for an attentive democracy where policymakers are better informed about public desires before initiating participatory processes. We introduce a novel, citizen-centric method for segmenting the population according to their participatory needs in energy transition decision-making. This approach surpasses existing typologies by aligning engagement processes more accurately with local needs, mitigating participation fatigue, and enhancing the effectiveness of participatory efforts.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"39 2","pages":"Article 107528"},"PeriodicalIF":2.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146001751","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}

This sequential approach can create operational risks, lead to inefficiencies, and distort the incentives of market participants in both the short and long run. I review these incentives by focusing on the Italian and Great Britain markets.

Consequently, the nature of the impacts that participant actions have on the operations of the broader power system are changing — for example, transmission constraints in renewable-heavy regions bind with more frequency, and the system security benefits provided by synchronous technologies become more relevant when the share of thermal generation decreases. However, the wholesale market design determines the extent to which whole-of-system costs and benefits from a participant’s actions enter their private operating incentives. This paper describes how power system constraints map to the wholesale market design behind Australia’s National Electricity Market (NEM). We then highlight inefficiencies stemming from pricing rules that do not accurately capture the value of transmission congestion and losses, and from an inability to co-optimize energy and system services tied to the commitment status of generating units. We use a series of cases to demonstrate why aligning the NEM’s market design with the physical realities of the power system should be a priority, with inaction to prevent the ability to operate a low-carbon grid at least-cost.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"39 1","pages":"Article 107489"},"PeriodicalIF":2.2,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147720204","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}

The strategies used were: (i) the collection of information from the legislation of the analyzed countries, environmental or energy agencies, scientific publications, international agreements, technical reports, etc., and (ii) a systematic review of articles published in the last 10 years on the impacts of wind power and its licensing around the world. As a result, the main problems observed in regulation were the absence of strong and specific laws on environmental licensing, the non-mandatory nature of Environmental Impact Assessments for wind activities or small-scale wind farms, delays in the licensing process, and the dispersion of license issuance across different agencies. In conclusion, it is emphasized that standardizing the wind power licensing process with the requirement of environmental impact studies, public participation, and efficient monitoring would be an appropriate method to prevent impacts resulting from licensing failures.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"38 4","pages":"Article 107513"},"PeriodicalIF":2.2,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145219504","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}

We summarize pricing trends, explore descriptive relationships, and employ regression models to quantify the influence of various factors. Although the recent national rise in retail prices has largely tracked inflation, state-level trends vary widely. We identify a number of factors that explain trends in subsets of states. States with the greatest price increases typically exhibited shrinking customer loads—partially linked to growth in net metered behind-the-meter solar—and had renewables portfolio standards (RPS) in concert with relatively costly incremental renewable energy supplies. By contrast, recent utility-scale wind and solar deployment that occurred outside RPS programs (but that benefited from tax incentives) had no discernible impact on increased retail prices. Hurricanes, storms and wildfires also contributed to sizable price increases in some states, most notably in California, where wildfire risk mitigation and liability insurance were major cost drivers. Fluctuations in natural gas prices—particularly following the onset of the Ukraine-Russia war—further contributed to sharp price increases through 2022–2023 in many states, with moderation in 2024. The relative influence of these factors varies across states and over time, and relationships may change in the future. Nonetheless, the findings underscore the diverse set of price determinants and highlight the need for continued research to inform effective policy and ensure customer affordability.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"38 4","pages":"Article 107516"},"PeriodicalIF":2.2,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145265832","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}
