This study evaluates the effectiveness of state-level policies on renewable energy (RE) generation capacity in the United States. Using a comprehensive panel dataset of 3017 counties from 2009 to 2019, we account for county-level variations in policy implementation and employ spatial panel models to capture spillover effects among neighboring counties. Our findings reveal that Renewable Portfolio Standards, expressed as percentage targets, significantly increase RE generation capacity across all sources. Property tax reductions boost solar and wind capacity but do not affect hydro and geothermal energy. In contrast, Energy Efficiency Resource Standards are negatively associated with hydro and geothermal capacity. Other policies, such as the Mandatory Green Power Option, sales tax incentives, and market deregulation, have shown no significant linkage with RE capacity. The results further indicate that spatial spillover effects are more pronounced for solar and wind generation capacity than for hydro and geothermal generation capacity. These findings highlight the need for tailored policies that consider the unique characteristics of each renewable energy source and account for regional interdependence in policy design.

At COP26, Vietnam pledged to reach Net-zero (NZ) emissions by 2050. To support this goal, this study introduces a model for developing local NZ pathways, with a focus on the energy sector—the largest source of emissions. It assesses the potential of renewable energy, forest carbon sinks, transport electrification, and energy efficiency to shape region-specific plans. Tay Ninh province, known for its high solar potential, and Quang Tri, rich in forest carbon sinks, are examined as case studies to demonstrate the differences in NZ pathways in solar-dominant and forest-dominant provinces. Based on the findings, feasible NZ scenarios and policy recommendations are proposed to guide local action, contributing meaningfully to Vietnam's national NZ roadmap.

Decentralised renewable energy (DRE) systems are widely acknowledged as a pragmatic route to universal electricity access in sub-Saharan Africa; yet, the comparative evidence on how regulatory weaknesses alter their scalability remains thin. Existing syntheses predominantly examine stable political economies (such as Kenya and Rwanda), leaving the political-economy dynamics of fragile states understudied. 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.

This study examines the determinants of stakeholder trust in the Public Utilities Regulatory Commission (PURC) of Ghana by investigating the influence of five (5) governance constructs (independence, transparency, effectiveness, regulatory responsiveness, and accountability). Drawing on the stakeholder theory and literature on regulatory governance, the study employed cross-sectional data using a sample of 280 stakeholders from various sectors. The findings provide strong empirical support for the hypothesized relationships between stakeholder trust and four of the constructs: independence, transparency, regulatory responsiveness, and effectiveness. However, accountability did not emerge as a statistically significant predictor. Perceived independence and effectiveness consistently demonstrate a statistically significant positive association with stakeholder trust, highlighting the centrality of institutional autonomy and performance in shaping confidence in regulatory institutions. Transparency and responsiveness are also relevant, albeit with relatively smaller effect sizes, indicating that while openness and attentiveness enhance stakeholder confidence, they do not outweigh the foundational importance of independence and institutional effectiveness. Taken together, these results advance both theoretical understanding and practical implications of how regulatory bodies in developing country contexts build and sustain trust among diverse stakeholders. Theoretically, the study contributes to scholarship on governance and stakeholder trust by reinforcing the salience of independence and effectiveness as essential qualities of regulatory legitimacy in developing countries. Practically, these findings carry important implications for regulatory policy and practice in Ghana and similar developing country contexts. PURC must strengthen its institutional independence from political interference and improve the perceived effectiveness of its regulatory mandate to improve stakeholder trust.

As environmental policies continue to proliferate, growing attention has turned to how one instrument may unintentionally offset or undermine the effectiveness of another. In China's power sector, for example, the Environmental Protection Tax (ET) may reduce emissions independently, but in doing so, it alters baseline conditions, depresses carbon prices, and weakens the incentive function of the Emissions Trading Scheme (ETS). This form of indirect policy interference has received limited empirical scrutiny. To address this gap, we develop a policy interaction framework to empirically assess the combined effects of ET and ETS in China's power sector. Leveraging a multi-period difference-in-differences model and variation in pilot policy implementation across provinces, we estimate the heterogeneous impacts of individual and joint policy treatments on carbon intensity. We also examine the transmission mechanism through which ET affects the carbon market by influencing allowance price dynamics. Our results show that both ETS and ET independently reduce carbon intensity, and that the effectiveness of ET increases with higher tax rates. However, when implemented concurrently, elevated tax rates suppress carbon prices and erode the market incentives intended by ETS. Mechanism analysis reveals that overlapping compliance costs can distort price signals and lead to suboptimal abatement behavior. These findings highlight a critical trade-off in hybrid environmental governance and underscore the need for better coordination between fiscal and market-based instruments to improve policy coherence and climate mitigation effectiveness, particularly in developing economies undergoing institutional transition.

The ability of a power system to balance network investment with demand flexibility services is key to a decarbonized energy system. However, integrating flexibility services into distribution network planning raises challenges of procurement design and market structure. This paper addresses the research gap concerning the economic implications of local flexibility markets where the distribution system operator (DSO) acts as the single buyer. We propose a procurement mechanism that embeds counterfactual investment valuation into a pay-as-bid clearing rule and determines equilibrium through Marshallian surplus maximization. The methodology is illustrated with numerical case studies that compare procurement outcomes under complete and incomplete supply offers. Results show that, even when some bids exceed the DSO's valuation threshold, accepting them can increase welfare, thereby delivering efficient and rational price signals. These findings challenge the view that monopsony inevitably distorts markets: when disciplined by transparent and auditable valuation, it can support neutrality and efficiency. The framework aligns with the forthcoming Network Code on Demand Response and Distribution Network Development Plans disclosed, offering regulators and DSOs a practical tool for market-based procurement and a ready candidate for regulatory sandboxes.

The increasing penetration of small-scale PV distributed generation in medium-voltage networks has introduced unexpected challenges. While PV generation reduces the real power drawn from the transmission grid, the absence of monetization for reactive power means that reactive demand remains unchanged. This mismatch results in declining power factors and potential financial penalties for DSOs. A local reactive power market offers an alternative solution, not for voltage stability but specifically for maintaining the power factor. This paper proposes a reactive market framework tailored for Turkiye, covering its operational steps, market-clearing process, demand elasticity, payment structure, and mathematical model. The framework incorporates a ±10% forecast tolerance to discourage gaming and promote fairness. It introduces the concept of a sustainability threshold to ensure that energy sustainability remains central to the system operations. Finally, two key regulatory proposals are discussed to accelerate implementation: spatial aggregation of power factor limits to increase competitiveness and dynamic, seasonally-adjusted thresholds to reflect demand seasonality.

Demand flexibility is a promising resource for demand-side management. Globally, with increased renewable penetration and electrified loads, utilities are developing robust frameworks to aggregate flexible loads for Demand Response and enhance grid decarbonisation. This research concentrates on a demand response programme, titled ‘Urja Arpan’ (Energy Sacrifice), implemented in New Delhi, India, and led by the utility company TATA Power Delhi Distribution Limited. This novel concept focuses on enhancing consumer engagement within an energy community, comprising residential, commercial, and industrial consumers, to alleviate grid strain and optimise network utilisation through demand flexibility. The DR programme currently involves 67,000 residential consumers and 24,600 commercial and industrial (C&I) consumers. The utility used smart meter data and program enrollment records to analyse participation trends and quantify peak load reduction during 2022–2024. The DR events achieved a flexible demand of 7.69 MW in 2022, 85 MW in 2023, and 560 MW in 2024, showing a remarkable increasing trend over the years. This demand response program offered no incentives or subsidies to residential, commercial, or industrial consumers for providing demand flexibility, a unique aspect of this work. Instead, every participant was nominated for a prize drawing after every DR event. The primary driving factors for participating consumers are energy savings and an interest in sustainable energy and environmental protection. The results demonstrate that community-based, non-monetary DR models can achieve utility-scale flexibility and could offer a sustainable pathway for decarbonising the grids.

This study applies Historical Institutionalism (HI) to analyze Taiwan's renewable-energy policies from 2016 to 2024, focusing on the interaction of institutional inertia and export-oriented decarbonization pressures. Taiwan's transition faces a “dual tension”: entrenched lock-in from low tariffs and centralized thermal power, and external demands such as the EU Carbon Border Adjustment Mechanism (CBAM), multinational supply-chain requirements, and tariff conflicts. CBAM, formally implemented in 2026, had already compelled anticipatory compliance and industrial adjustments in 2025 through trade-related rules and supply-chain demands. The study advances a “dual tension framework,” illustrating both the theoretical value of HI and concrete policy lessons for other export-dependent economies.

This paper aims to navigate the evolution of Smart Grid Cybersecurity (SGCS) by conducting a comprehensive review of evolving challenges and proposing a collaborative framework for long-term security. A systematic analysis is conducted to reveal the research paradigm and evolution path of SGCS on a global scale. Advanced data analysis techniques are applied to produce research outputs, including key themes, graphical clusters, and science mapping of evolutionary trajectories in SGCS. Intrusion detection, critical infrastructure protection, and information and communications technology are identified as the three pivotal themes shaping the development and research frontiers of SGCS. To effectively address the challenges facing SG systems, particularly the secure integration of heterogeneous technologies, and to ensure long-term security, a collaborative framework is established. This framework involves key stakeholders in cybersecurity policies, business strategies, innovative technologies, and public participation. Further development trends and research ideas regarding each factor are discussed. Partnership among the stakeholders is emphasized to ensure the industry's future sustainability and long-term security. This study offers significant value to academics and practitioners by offering a comprehensive review of SGCS development, insights to guide future research, and a collaborative approach that can inform decision-making and promote enduring security strategies.

Advanced data analysis techniques are applied to produce research outputs, including key themes, graphical clusters, and science mapping of evolutionary trajectories in SGCS. Intrusion detection, critical infrastructure protection, and information and communications technology are identified as the three pivotal themes shaping the development and research frontiers of SGCS. To effectively address the challenges facing SG systems, particularly the secure integration of heterogeneous technologies, and to ensure long-term security, a collaborative framework is established. This framework involves key stakeholders in cybersecurity policies, business strategies, innovative technologies, and public participation. Further development trends and research ideas regarding each factor are discussed. Partnership among the stakeholders is emphasized to ensure the industry's future sustainability and long-term security. This study offers significant value to academics and practitioners by offering a comprehensive review of SGCS development, insights to guide future research, and a collaborative approach that can inform decision-making and promote enduring security strategies.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"97 ","pages":"Article 102081"},"PeriodicalIF":4.4,"publicationDate":"2025-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145324385","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}
