Although prior studies have highlighted post-Fukushima shifts in nuclear perceptions, there are limited details regarding the factors driving SMR adoption. This study examines the factors influencing nuclear experts' perceptions of SMRs from the perspectives of nuclear experts in South Korea and Japan, two nations where nuclear power policies and public perceptions have evolved significantly since the Fukushima Daiichi disaster. Using the analytic hierarchy process (AHP), we evaluated four primary criteria—safety, economic feasibility, environmental impact, and social factors—through surveys of 45 Korean and 18 Japanese experts. The results indicated that safety is the primary driver in both contexts, with a particular focus on accident prevention and the secure and stable operation of reactors. However, Korean experts tended to emphasize waste management and greenhouse gas reduction, aligning with the country's focus on decarbonization, whereas Japanese experts underscored cost-effectiveness and cybersecurity, consistent with heightened risk awareness following the Fukushima disaster. These findings highlight that robust policy frameworks, clear incentives, and communication strategies are crucial for fostering public trust and accelerating SMR adoption. In nations where public skepticism regarding nuclear energy is high, transparency in risk management and alignment with broader clean energy objectives can reinforce perceptions. By integrating qualitative insights from expert hearings with quantitative AHP-based surveys, this study provides guidance to policymakers, industry leaders, and researchers as they consider the feasibility of SMRs in the transition to a more sustainable energy future.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"98 ","pages":"Article 102109"},"PeriodicalIF":4.4,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145614475","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}

Similarly, residential systems integrating invisible PV capacity achieve an average NPV enhancement of 26 % compared to BAU projects. To mitigate this issue, this research proposes a minimization strategy featuring an on-top penalty fee. Sensitivity analysis shows that the proposed fee structure, when strategically set within the 0.07–0.08 USD/kWh range, achieves the reduction in unauthorized project returns. This range is set explicitly below the average retail tariff rate but above the system's Levelized Cost of Energy (LCOE), thereby promoting fairness while effectively disincentivizing invisible PV adoption and addressing a critical gap in energy policy.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"98 ","pages":"Article 102116"},"PeriodicalIF":4.4,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145681291","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}

However, provinces currently act independently regarding electricity consumption, making it difficult to simultaneously reduce the costs of their renewable energy consumption responsibility weights (CRWs) while increasing electricity revenue. To solve this problem, we constructed a bi-level multi-objective cross-provincial renewable energy consumption transfer fees model (CTFM), in which the central government is the upper level and provincial governments are the lower level. The leader sets the prices for renewable energy consumption transfer fees to minimize the total cost caused by the CRWs and maximize electricity revenue within the cooperative region. Followers then respond to the leader's transfer fees by optimizing their electricity consumption strategies to reduce the cost of their CRW and increase electricity revenue. The model is solved using bi-level programming combined with a relaxation approach and is applied to a cooperative region comprising Beijing, Shandong, Hebei, and Inner Mongolia. Compared with the independent approach, a transfer price of 0.351 CNY/kWh allowed the CTFM to reduce the fulfillment cost by 206.869 × 10^8 CNY (13.785 %) and increase electricity revenue by 1779.845 × 10^8 CNY (5.718 %).

This paper closes that gap by analysing how policy and regulatory frameworks shape the deployment of DRE outcomes in Nigeria, Liberia, and Malawi, three countries that score below regional means on the African Development Bank's Electricity Regulatory Index and the World Bank's Regulatory Indicators for Sustainable Energy. Employing a qualitative comparative case-study design, we (i) trace within-case causal chains through document-based process-tracing and (ii) test cross-case convergence using pattern-matching on six governance dimensions validated by recent benchmarking literature. The evidence base integrates legal texts, donor reports, and the Electricity Regulatory Index/Regulatory Indicators for Sustainable Energy time series, triangulated to ensure reliability and validity. Findings reveal that overlapping mandates, weak enforcement capacity, and fragmented donor engagement systematically hinder the deployment of DRE, whereas targeted policy innovations, such as Nigeria's state-level minigrid licensing, demonstrate pathways to improvement. We offer actionable lessons on institutional alignment, donor coordination, and tariff reform that can inform regulatory upgrades in similarly constrained settings. By foregrounding fragile-state contexts, the study enriches comparative DRE scholarship and provides a diagnostic framework that is transferable to other low-capacity energy systems.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"98 ","pages":"Article 102075"},"PeriodicalIF":4.4,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145365020","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}

Using spatial econometric models on panel data from 30 Chinese provinces (2008–2021), we identify distinct mechanisms on each side of the analysis. On the demand side, EISA reduces the share of fossil fuel consumption and mitigates marketization-induced fossil energy use, yet it weakens the effectiveness of environmental regulation. Stricter environmental regulations can reduce the consumption of fossil energy, further promoting cleaner energy use by positively moderating EISA and weakening the tangential effects of marketization. Although marketization initially stimulates fossil energy consumption, it ultimately enhances the effectiveness of environmental regulations and optimizes the allocation of EISA. On the supply side, EISA significantly promotes local new energy production. However, it generates negative spatial spillover effects and inhibits the development of renewable energy in neighboring regions. Environmental regulations promote new energy production most significantly in the eastern region of the country, but they also cause similar negative spillover patterns. Marketization processes suppress new energy production overall, with pronounced regional disparities. This study contributes empirical evidence regarding spatial spillovers and regional heterogeneity in China's energy transition process. The findings may provide a scientific basis for integrating synergistic development cross-regionally, as well as optimizing conjoined environmental regulations and market-oriented policies.
