The growing integration of solar photovoltaic (PV) systems in Thailand is primarily driven by declining system costs and incentive schemes. This trend has concurrently led to the challenge of “invisible” PV installations. These installations fall into two categories: (1) exceeding the contracted specification, and (2) unnotified behind-the-meter connections that result in unintended meter reversal (‘meter-run-backward’). This study examines the financial evaluation of invisible PV installations by comparing their profitability with that of business-as-usual (BAU) projects. The analysis focuses on both centralized and residential PV systems under various incentive schemes, including Net Billing and Net Energy Metering.
Our finding reveals a significant economic distortion that the Net Present Value (NPV) of a centralized PV project incorporating hidden (invisible) capacity can increase by as much as 20.54 % relative to a baseline scenario, representing an average 6.53 % improvement over BAU compliance. 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.
泰国太阳能光伏(PV)系统的日益一体化主要是由系统成本下降和奖励计划推动的。这一趋势同时也带来了“隐形”光伏装置的挑战。这些安装分为两类:(1)超出合同规格;(2)未通知的表后连接导致意外的仪表反转(“仪表倒跑”)。本研究通过将隐形光伏装置的盈利能力与常规商业(BAU)项目的盈利能力进行比较,对其进行财务评估。分析的重点是集中式和住宅光伏系统在各种激励方案下,包括净账单和净能源计量。我们的发现揭示了一个显著的经济扭曲,一个包含隐藏(不可见)容量的集中式光伏项目的净现值(NPV)相对于基线情景可以增加20.54%,比BAU合规平均提高6.53%。同样,与BAU项目相比,集成隐形光伏容量的住宅系统平均净现值提高了26%。为了缓解这一问题,本研究提出了一种以最高罚款为特征的最小化策略。敏感性分析表明,当策略设置在0.07-0.08美元/千瓦时范围内时,可实现对未授权项目收益的降低。该范围明确设定为低于平均零售电价,但高于系统的平准化能源成本(LCOE),从而促进了公平,同时有效地抑制了隐形光伏的采用,并解决了能源政策中的一个关键缺口。

Energy market stability is vital for global economic growth, yet increasing financial, geopolitical, and climate uncertainties have heightened cross-market risks. Although artificial intelligence (AI) has emerged as a transformative driver of technology and energy systems, its financial connections to energy markets remain underexplored. Existing studies primarily focus on traditional assets or clean energy linkages, overlooking AI as a distinct asset class in global risk transmission. This study investigates the dynamic risk correlations between AI assets and energy markets using a mixed-frequency DCC-MIDAS(-X) framework over the period March 2018 to December 2023, encompassing major events such as the COVID-19 pandemic and the 2022 energy crisis. The results reveal four key findings. (1) AI assets act as an effective hedge for natural gas and China's INE crude oil and a moderate diversifier for WTI, Brent, gasoline, and gas oil. (2) A persistently strong correlation exists between AI and clean energy, reflecting deep technological and investment integration. (3) Pronounced regional heterogeneity is identified: Western benchmarks exhibit stronger AI linkages than Asian and Middle Eastern markets. (4) Dollar fluctuation, climate policy uncertainty, and economic policy uncertainty significantly strengthen AI-energy correlations, while trade and geopolitical risks have weak effects. Overall, the findings highlight the growing financial interconnectedness between the technology and energy sectors. The study contributes by incorporating a regional comparative perspective and identifying macro-policy drivers of AI-energy linkages, offering implications for coordinated policy design and strategic portfolio diversification.
能源市场稳定对全球经济增长至关重要,但日益增加的金融、地缘政治和气候不确定性加剧了跨市场风险。尽管人工智能(AI)已成为技术和能源系统的变革性驱动力,但其与能源市场的金融联系仍未得到充分探索。现有的研究主要集中在传统资产或清洁能源的联系上,忽视了人工智能在全球风险传递中的独特资产类别。本研究使用混合频率DCC-MIDAS(-X)框架,调查了2018年3月至2023年12月期间人工智能资产与能源市场之间的动态风险相关性,包括COVID-19大流行和2022年能源危机等重大事件。研究结果揭示了四个关键发现。(1)人工智能资产是天然气和中国INE原油的有效对冲工具,也是WTI、布伦特、汽油和天然气的适度多元化工具。(2)人工智能与清洁能源之间存在持续的强相关性,体现了技术与投资的深度融合。(3)发现了明显的区域异质性:西方基准比亚洲和中东市场表现出更强的人工智能联系。(4)美元波动、气候政策不确定性和经济政策不确定性显著增强了人工智能-能源相关性,而贸易和地缘政治风险的影响较弱。总体而言,研究结果突显了科技和能源部门之间日益增长的金融互联性。该研究的贡献在于纳入了区域比较视角,并确定了人工智能-能源联系的宏观政策驱动因素,为协调政策设计和战略组合多样化提供了启示。

The paper examines the significance of sustainable development and energy efficiency, particularly in household energy conservation. The research focuses on household energy efficiency, including purchases related to solar panel adoption. The motivation for this research was to raise awareness of the importance of utilizing renewable energy sources in Serbia. In this context, a dynamic approach to the Theory of Planned Behavior (TPB) was applied to analyze differences in the influence of psychological determinants on the intention to purchase solar panels, depending on the phase of behavior change (pre-decision phase, pre-action phase, and action phase) in which the decision-maker is currently situated. To the authors’ knowledge, this represents the first application of the dynamic TPB approach to understanding the intention to adopt the use of solar panels in the Republic of Serbia. Data analysis was conducted using Structural Equation Modeling (SEM). The results indicate that in the pre-decision and action phases, attitudes have a statistically significant effect on the intention to purchase solar panels, while in the pre-action phase, all three TPB determinants exhibit a statistically significant influence. The paper also presents managerial implications and policy recommendations to motivate citizens and businesses to use energy more efficiently and adopt products powered by renewable energy sources.
本文探讨了可持续发展和能源效率的意义,特别是在家庭节能方面。这项研究的重点是家庭能源效率,包括与太阳能电池板采用相关的购买。这项研究的动机是提高对塞尔维亚利用可再生能源重要性的认识。在此背景下,采用计划行为理论(TPB)的动态方法分析了心理决定因素对购买太阳能电池板意愿的影响差异,这取决于决策者当前所处的行为变化阶段(决策前阶段、行动前阶段和行动阶段)。据作者所知,这是第一次应用动态TPB方法来理解塞尔维亚共和国采用太阳能电池板的意图。数据分析采用结构方程模型(SEM)。结果表明,在决策前和行动阶段,态度对太阳能电池板购买意愿的影响具有统计学意义,而在行动前阶段,所有三个TPB决定因素都表现出统计学意义上的影响。本文还提出了管理启示和政策建议,以激励公民和企业更有效地利用能源,采用可再生能源驱动的产品。

Evaluating Natural Gas Pipeline Integrity Management (NGPIM) efficiency is essential for ensuring pipeline performance and continuous improvement. Traditional evaluation methods typically concentrate on assessing historical efficiencies at the enterprise level of operators and are unable to forecast future efficiency. This study proposes a DEA–Malmquist–ML model to evaluate and predict NGPIM efficiency across 42 U.S. states. From 2010 to 2023, 18 states recorded average annual static efficiency above 1, showing an “eastern high, western low” spatial pattern, while 37 states exhibited dynamic efficiency above 1, mainly driven by technological progress and scale efficiency change. Overall, U.S. NGPIM efficiency remains high and shows a gradual upward trend. Panel Tobit regression identifies factors influencing static and dynamic efficiency. The proposed SACBi-LSTM model—integrating Convolutional neural network, bi-directional long and short-term memory network, and sparse attention—achieves 90 % average accuracy across 11 indicators, with prediction errors for 33 states within 0.1, confirming strong model adaptability. This regional efficiency evaluation and forecasting framework supports evidence-based policymaking and rational resource allocation.
评估天然气管道完整性管理(NGPIM)效率对于确保管道性能和持续改进至关重要。传统的评估方法通常侧重于评估运营商在企业层面的历史效率,而无法预测未来的效率。本研究提出了DEA-Malmquist-ML模型来评估和预测美国42个州的NGPIM效率。2010 - 2023年,18个州年均静态效率高于1,呈现“东高西低”的空间格局;37个州年均动态效率高于1,主要受技术进步和规模效率变化驱动。总体而言,美国的NGPIM效率仍然很高,并呈现逐步上升的趋势。面板Tobit回归识别影响静态和动态效率的因素。所提出的SACBi-LSTM模型集成了卷积神经网络、双向长短期记忆网络和稀疏注意力,在11个指标上的平均准确率达到90%,对33个状态的预测误差在0.1以内,证实了较强的模型适应性。该区域效率评价与预测框架支持循证决策和资源合理配置。

The sustainability of water supply represents a critical global challenge. A pivotal factor in addressing this challenge is the implementation of water tariffs, which function as an indispensable mechanism for securing the long-term availability of this invaluable resource. However, a comprehensive synthesis of the essential dimensions that underpin effective tariff design across diverse sectors remains conspicuously absent, thereby impeding the formulation of effective policy development. This study aims to bridge the gap by conducting a systematic literature review that identifies and analyzes the fundamental dimensions of water tariffs from a supply-side sustainability perspective, as articulated in contemporary literature spanning domestic, industrial, and agricultural sectors across various countries and regions. These insights have the potential to enhance the supply-side approach to water management. Employing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline and a Mixed Methods Appraisal Tool (MMAT), we scrutinized 16 studies. Through thematic analysis, we discerned six key interconnected dimensions of water tariffs: affordability, efficiency, financial sustainability, regulatory framework, conservation incentives, and the sustainability of water resources, which were further delineated into 11 sub-themes. The originality of this study resides in articulating these supply-side conceptual dimensions, synthesizing disparate themes into a cohesive framework, and illuminating critical trade-offs, particularly between affordability and financial sustainability. This study serves as a vital reference for policymakers and water utilities, providing an evidence-based tool for devising multi-objective water pricing strategies that are effective in managing demand and ensuring the long-term security of the water supply.
供水的可持续性是一项重大的全球挑战。应对这一挑战的一个关键因素是实施水费,这是确保这一宝贵资源长期供应的不可或缺的机制。然而,对支撑跨不同部门有效关税设计的基本维度的全面综合仍然明显缺乏,从而阻碍了有效政策制定的制定。本研究旨在通过进行系统的文献综述,从供应方可持续性的角度确定和分析水费的基本维度,弥合这一差距,正如当代文献中所阐述的那样,涵盖了各个国家和地区的国内、工业和农业部门。这些见解有可能加强水管理的供应方方法。采用系统评价和荟萃分析首选报告项目(PRISMA)指南和混合方法评估工具(MMAT),我们仔细审查了16项研究。通过专题分析,我们发现了水费的六个相互关联的关键维度:可负担性、效率、财务可持续性、监管框架、保护激励和水资源可持续性,并进一步划分为11个子主题。这项研究的独创性在于阐明了这些供给方面的概念维度,将不同的主题综合到一个有凝聚力的框架中,并阐明了关键的权衡,特别是在可负担性和财务可持续性之间。该研究为政策制定者和水务公司提供了重要参考,为制定有效管理需求和确保供水长期安全的多目标水价策略提供了基于证据的工具。

Achieving universal access to water and sanitation services (WSS) is one of the most significant public challenges in Brazil. The WSS are encompassed within the concept of ‘basic sanitation,’ which includes a comprehensive approach to policy interventions aimed at protecting public health and the environment. This broader definition incorporates potable water supply, wastewater collection and treatment, solid waste management, and urban drainage and stormwater management (UDSM). However, these services have evolved disproportionately, with a focus on water supply and wastewater treatment. As a result, despite the critical importance of UDSM in urban areas, many Brazilian cities lack these services, leaving both populations and the environment vulnerable to adverse impacts. Although the reasons for this imbalance among services might be justified according to the priority of indispensable services, the UDSM has also proved essential to a broader concept of urban security, health, and sustainability. This article explores the asymmetries between UDSM and other WSS within Brazil's new regulatory framework, following the enactment of Law No. 14,026/2020. The findings reveal that, in the absence of institutional drivers rooted in the historical asymmetries observed during the consolidation of the National Water and Sanitation Policy (NWSP), UDSM services remain marginalized and face inertia in public policy. If this trend persists, UDSM services are unlikely to follow the same trajectory of improvement seen in other WSS, ultimately undermining the goal of achieving universal access to basic sanitation.
实现普遍获得水和环境卫生服务(WSS)是巴西最重大的公共挑战之一。《世界卫生宣言》包含在“基本卫生”概念中,其中包括旨在保护公众健康和环境的政策干预的综合办法。这个更广泛的定义包括饮用水供应、废水收集和处理、固体废物管理以及城市排水和雨水管理(UDSM)。然而,这些服务已经不成比例地发展,重点是供水和废水处理。因此,尽管UDSM在城市地区至关重要,但许多巴西城市缺乏这些服务,使人口和环境容易受到不利影响。虽然根据必不可少的服务的优先次序,各服务之间这种不平衡的原因可能是合理的,但UDSM也证明对更广泛的城市安全、健康和可持续性概念至关重要。本文探讨了在第14026 /2020号法律颁布后,巴西新监管框架内UDSM与其他WSS之间的不对称性。研究结果表明,由于在国家水和卫生政策(NWSP)巩固过程中观察到的历史不对称,缺乏制度性驱动因素,UDSM服务仍然被边缘化,并面临公共政策的惰性。如果这种趋势持续下去,UDSM的服务不太可能遵循其他WSS所看到的改善轨迹,最终破坏实现普遍获得基本卫生设施的目标。

Even if in Italy district heating and cooling (DHC) accounts for only a small share of thermal energy demand, the sector, primarily based on fossil fuels, is expected to grow. Therefore, increasing the share of DHC and decarbonising the DHC sector are crucial for Italy's climate targets. This paper identifies the main barriers and drivers for Italy's DHC sector through a hybrid approach combining a normative review with direct engagement. Among others, the EU-funded SupportDHC project includes activities to highlight technical and non-technical barriers, supported by a structured capacity-building programme with key Italian operators and stakeholders, such as local administrators, associations, and authorities. Results underscore regulatory uncertainty, fragmented planning processes, insufficient economic incentives, technical integration issues, and limited public awareness as major obstacles. Stakeholders' collaboration proved effective in shaping consensus-based solutions, such as clearer policy frameworks, streamlined procedures, and enhanced investment mechanisms. The study concludes that integrating structured stakeholders' participation into policy and planning processes can substantially accelerate the expansion and decarbonisation of Italy's DHC systems.
即使在意大利,区域供热和供冷(DHC)仅占热能需求的一小部分,但该行业(主要基于化石燃料)预计将增长。因此,增加DHC的份额并使DHC部门脱碳对意大利的气候目标至关重要。本文通过将规范审查与直接参与相结合的混合方法,确定了意大利DHC部门的主要障碍和驱动因素。除此之外,欧盟资助的SupportDHC项目包括强调技术和非技术障碍的活动,由意大利主要运营商和利益相关者(如当地管理员、协会和当局)的结构化能力建设计划提供支持。结果强调,监管不确定性、规划过程碎片化、经济激励不足、技术整合问题和公众意识有限是主要障碍。事实证明,利益攸关方的合作在形成基于共识的解决方案方面是有效的,例如更明确的政策框架、简化的程序和加强的投资机制。该研究的结论是,将有组织的利益相关者参与到政策和规划过程中可以大大加速意大利DHC系统的扩张和脱碳。

As global decarbonization intensifies, nuclear energy has received renewed attention, primarily through small modular reactors (SMRs). 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.
随着全球脱碳的加剧,核能主要通过小型模块化反应堆(smr)重新受到关注。尽管先前的研究强调了福岛核事故后人们对核的看法发生了转变,但关于推动采用小型堆的因素的细节有限。本研究从韩国和日本的核专家的角度考察了影响核专家对小型反应堆看法的因素,这两个国家的核电政策和公众看法自福岛第一核电站灾难以来发生了重大变化。通过对45名韩国专家和18名日本专家的调查,我们使用层次分析法(AHP)评估了四个主要标准——安全性、经济可行性、环境影响和社会因素。结果表明,在这两种情况下,安全都是主要驱动因素,尤其关注事故预防和反应堆的安全稳定运行。然而,韩国专家倾向于强调废物管理和减少温室气体,这与该国对脱碳的关注相一致,而日本专家则强调成本效益和网络安全,这与福岛灾难后提高的风险意识相一致。这些发现突出表明,强有力的政策框架、明确的激励措施和沟通战略对于促进公众信任和加速采用小型管理系统至关重要。在公众对核能持高度怀疑态度的国家,风险管理的透明度以及与更广泛的清洁能源目标的一致性可以加强人们的看法。通过将专家听证会的定性见解与基于ahp的定量调查相结合,本研究为政策制定者、行业领导者和研究人员提供了指导,帮助他们考虑smr在向更可持续的能源未来过渡中的可行性。

Measuring a paradox: Zero-negative electricity prices 衡量一个悖论:零负电价

The share of renewables and the number of hours with zero or negative prices in day-ahead markets are increasing in many countries. During these hours, some synchronous generators that are not scheduled are activated by system operators at a high cost to ensure minimum reliable operating conditions. As a result, customers experience a paradox when they see positive end costs during hours with zero-negative energy prices, which incentivizes them to reduce consumption when there is a surplus of renewable energy. We use ARMA-GARCH methods to analyze the costs of ancillary services in the Spanish power system (2023–2024) and their relationship with the hourly day-ahead prices and electricity demand. Cost of ancillary services increases by +0.045 €/MWh for each euro reduction in day-ahead prices, and by 0.182 €/MWh for each additional GWh of total scheduled energy demand. Our main conclusion is that, in a renewable-reliant system, electricity prices fail to signal customers, and the total operating system cost of electricity should consider the vertical sum of the energy cost and ancillary service cost. Similar results can be expected in other countries with a high share of renewable energy. Policy should prioritize reducing ancillary service costs to signal customers efficiently.
在许多国家,可再生能源的份额以及日前市场中零电价或负电价的小时数都在增加。在这段时间内,一些未被调度的同步发电机被系统操作员以高成本激活,以确保最低的可靠运行条件。因此,当客户在能源价格为零的情况下看到正的终端成本时,他们会遇到一个悖论,这激励他们在可再生能源过剩时减少消费。我们使用ARMA-GARCH方法来分析西班牙电力系统(2023-2024)的辅助服务成本及其与每小时日前价格和电力需求的关系。日前电价每降低1欧元,辅助服务成本就增加+0.045欧元/兆瓦时;计划总能源需求每增加1吉瓦时,辅助服务成本就增加0.182欧元/兆瓦时。我们的主要结论是,在一个依赖可再生能源的系统中,电价不能向客户发出信号,电力的总运营系统成本应该考虑能源成本和辅助服务成本的垂直总和。可再生能源占比较高的其他国家也会出现类似的结果。政策应优先考虑降低辅助服务成本,以有效地向客户发出信号。

The World Health Organization recommends Water Safety Plans (WSP) as the most effective means of ensuring safe drinking-water supply. WSP performance evaluation is necessary for improving water service delivery, scaling up, and motivating the roll out of WSP. In this study, the evaluation of WSP development and implementation was done in Bushenyi-Ishaka Municipality, a mid-sized semi-rural town in southwestern Uganda. Training of operations staff and the WSP team was done. Performance indicator data were collected before, during, and after 18 months of WSP implementation to determine the changes attributable to this intervention. Structured semi-quantitative questionnaires were used for data collection, which consisted of 11 progressive outcome indicators categorized under operational and institutional changes, and 14 short-term impact indicators categorized under water supply change. Results showed that WSP implementation enabled improvement in infrastructure, operational monitoring, customer engagement meetings, and training. Implementation of WSP did not result in improved catchment management, development and review of standard operating procedures and holding of internal meetings. Regarding short-term impacts, there was a significant improvement in compliance levels with drinking water quality standards, continuity of water supply, and customer satisfaction, as assessed by the frequency of complaints. There was, however, a significant reduction in the revenue-cost ratio (p = 0.001), likely due to an inadequate budget for implementing service expansion.
世界卫生组织建议将水安全计划作为确保安全饮用水供应的最有效手段。科进绩效评估对于改善供水服务交付、扩大规模和推动科进的推广是必要的。在这项研究中,对WSP的开发和实施进行了评估,该评估是在乌干达西南部的一个中型半农村城镇Bushenyi-Ishaka市进行的。对操作人员和科进团队进行了培训。在实施WSP之前、期间和之后的18个月收集了绩效指标数据,以确定该干预措施导致的变化。数据收集采用结构化半定量问卷,其中包括11个业务和制度变化分类的渐进式结果指标和14个供水变化分类的短期影响指标。结果显示,WSP的实施在基础设施、操作监控、客户参与会议和培训方面进行了改进。水务服务计划的实施并没有改善集水区的管理、制订和检讨标准作业程序,以及举行内部会议。就短期影响而言,在符合饮用水水质标准的水平、供水的连续性和顾客满意度(以投诉频率衡量)方面均有显著改善。然而,收入成本比显著降低(p = 0.001),可能是由于执行服务扩展的预算不足。
