CiFi PV projects facilitate broader public participation in solar energy, particularly among those unable to install their own rooftop systems. Despite their potential, these projects are under-researched. This study explores whether CiFi PV can engage diverse populations or if it mainly attracts the same individuals as personal rooftop PV. It examines the role of tacit and explicit knowledge, as measured by education and solar experience, in the acceptance of CiFi PV, as well as in the evaluation of project characteristics that motivate people to choose CiFi PV. Using a Swiss conjoint experiment, findings suggest that the inclusive potential of CiFi PV may be limited, with similar preferences observed across knowledge groups.
外国投资公司的光伏项目促进了更广泛的公众参与太阳能,特别是那些无法安装自己的屋顶系统的人。尽管这些项目很有潜力,但研究还不够充分。本研究探讨了CiFi光伏是否可以吸引不同的人群,或者它是否主要吸引与个人屋顶光伏相同的人群。它考察了隐性知识和显性知识的作用,通过教育和太阳能经验来衡量,在接受CiFi光伏方面,以及在评估激励人们选择CiFi光伏的项目特征方面。利用瑞士联合实验,研究结果表明,CiFi光伏的包容性潜力可能是有限的,在各个知识群体中观察到类似的偏好。

Environmental performance of urban transport infrastructure (EPUTI) reflects the positive influence of urban transport infrastructure on the natural environment. It is influenced by various determinants, including the inputs of its operational facilities and numerous urban economic and social development factors. In addition, urban transport infrastructure encompasses multiple categories of transportation modes, and their environmental performances may differ; however, they are typically influenced by similar factors. Therefore, it is necessary to use a scientific method to analyze their determinants jointly. This paper examines the environmental performance of different categories of urban transport infrastructure and their determinants, taking six megacities in China as examples. Their EPUTIs are evaluated by the entropy method. The seemingly unrelated regression models are employed to analyze the determinants of the environmental performance across different categories of urban transport infrastructure. The results display that 1) the improvement of environmental performance of urban bus was not significantly relied on the increase of its operational vehicles; 2) the improvement of environmental performance of urban rail transit was mainly relied on the enlargement of scales of their operational vehicles and environmental performance of urban road was significantly negatively affected by the scale of civilian car ownership; 3) urban economic and population scales were still the important determinants of environmental performance of urban transport infrastructure; 4) the investment intensity of urban transport infrastructure and urban technological level have weaker impacts on environmental performance of urban transport infrastructure.
城市交通基础设施环境绩效反映了城市交通基础设施对自然环境的积极影响。它受到各种决定因素的影响,包括其业务设施的投入以及许多城市经济和社会发展因素。此外,城市交通基础设施包含多种运输方式,其环境绩效可能存在差异;然而,它们通常受到类似因素的影响。因此,有必要用科学的方法对它们的决定因素进行综合分析。本文以中国6个特大城市为例,研究了不同类型城市交通基础设施的环境绩效及其影响因素。用熵值法计算了它们的等效熵值。采用看似不相关的回归模型分析了不同类别城市交通基础设施环境绩效的决定因素。结果表明:1)城市公交环境绩效的改善对运营车辆的增加依赖不显著;②城市轨道交通环境绩效的提升主要依赖于运营车辆规模的扩大,城市道路环境绩效受民用汽车保有量规模的显著负向影响;③城市经济规模和人口规模仍然是城市交通基础设施环境绩效的重要决定因素;④城市交通基础设施投资强度和城市技术水平对城市交通基础设施环境绩效的影响较弱。

This paper examines Türkiye's three-pillar energy-poverty strategy (2019–2023), focusing on the Maximum Settlement Price (AUF), a universal market-wide tariff intervention functionally similar to an inframarginal cap. Using high-frequency EPİAŞ prices and DisCo-level indicators (disconnections, consumption), the analysis shows that AUF acts as an implicit consumer subsidy and, together with the 240-kWh tier, improves affordability for low-consumption users, especially in Eastern and Southeastern regions. Reframing a mechanism often criticized for lowering producer revenues, the study documents its distributional footprint on vulnerable households. By linking market design to energy-poverty outcomes, it offers a cost-effective, replicable template for behavior-informed targeting under crisis conditions.
本文研究了 rkiye的三支柱能源贫困战略(2019-2023),重点关注最高结算价格(AUF),这是一种普遍的市场范围内的关税干预,功能类似于超边际上限。使用高频EPİAŞ价格和迪斯科水平指标(断网、消费),分析表明,AUF作为一种隐性消费者补贴,与240千瓦时的电价层一起,提高了低消费用户的负担能力。特别是在东部和东南部地区。该研究重新构建了一种经常因降低生产者收入而受到批评的机制,记录了其对弱势家庭的分配足迹。通过将市场设计与能源贫困结果联系起来,它为危机条件下的行为知情定向提供了一个具有成本效益、可复制的模板。

The Feed-in Tariff (FIT) scheme in the UK was designed to promote residential solar photovoltaic (PV) projects by offering fixed payments for electricity generated, thereby positioning solar PV as an investment opportunity for households. This study investigates the role of income in shaping the uptake of solar PV under the FIT scheme and assesses the intertemporal fairness of the financial returns it provides. Using data from 323 local authority districts, the analysis focuses on two major installation peaks in 2011 and 2015, which correspond to significant changes in tariff rates. The findings reveal a positive relationship between income and solar PV adoption during the first peak, but a negative relationship in the second. This shift suggests that as installation costs declined, lower-income regions began to catch up in adopting solar PV. However, by estimating the expected (ex ante) rates of return across these periods, the study identifies a substantial decline in returns, both between the two peaks and following sharp reductions in tariff rates. These results indicate that early adopters in higher-income regions achieved significantly higher financial returns than those who adopted later. The study reveals a form of intertemporal unfairness embedded in the FIT scheme, confirming the need for more frequent and responsive tariff adjustments to ensure consistent investment incentives over time.
英国的上网电价(FIT)计划旨在通过为发电提供固定支付来促进住宅太阳能光伏(PV)项目,从而将太阳能光伏定位为家庭投资机会。本研究探讨了在FIT计划下,收入对太阳能光伏发电吸收的影响,并评估了其提供的财务回报的跨期公平性。使用来自323个地方政府区的数据,分析重点关注2011年和2015年的两个主要安装高峰,这两个高峰对应于电价的重大变化。研究结果显示,在第一个高峰期间,收入与太阳能光伏采用率呈正相关关系,但在第二个高峰期间呈负相关关系。这种转变表明,随着安装成本的下降,低收入地区开始赶上采用太阳能光伏。然而,通过估算这些时期的预期(事先)回报率,该研究发现,在两个峰值之间以及关税税率大幅降低之后,回报率都出现了大幅下降。这些结果表明,在高收入地区,早期采用者获得的财务回报明显高于后来采用者。该研究揭示了上网电价补贴计划中存在的一种跨期不公平,证实了需要更频繁、更及时地调整关税,以确保长期持续的投资激励。

This study provides a historical framework of the cumulative mandates of water supply utilities: universal coverage, commercial viability, and sustainability. The political agendas, development programs, and societal demands that have led to this overlap of multiple, and at times competing, mandates are discussed to inform the complexity water utilities face. Further, the detrimental effect of climate change, demographic change, urbanization, pollution, and ageing infrastructure on achieving these mandates is explained. Water utility management is portrayed as becoming increasingly complex, resulting in a need for more diverse knowledge, skills, and capacities in addressing the challenges facing water utilities.

The relationship between electric vehicle (EV) stock and electricity consumption is complex, with many factors influencing both variables. Furthermore, higher EV adoption can have adverse and unforeseen impacts on electrical networks and generation capacity requirements, necessitating the development of proactive policies and tariff decisions. To this end, this study investigates this relationship for 20 European countries from 2000 until 2022, utilising an Error Correction Model to estimate the impact of EV sales on electricity consumption. Results indicate positive and statistically significant results for certain sub-samples, which can have far-reaching implications for policymakers and generation and network capacity planners.
电动汽车保有量与用电量之间的关系是复杂的,影响这两个变量的因素很多。此外,更高的电动汽车采用率可能对电网和发电容量需求产生不利和不可预见的影响,因此有必要制定积极的政策和关税决策。为此,本研究调查了2000年至2022年20个欧洲国家的这种关系,利用误差修正模型来估计电动汽车销售对电力消耗的影响。结果表明,某些子样本的结果具有统计学意义,这对政策制定者、发电和网络容量规划者具有深远的影响。

Backup power or bill savings? How electricity tariffs impact residential solar-plus-storage usage in the United States 备用电源还是节省电费?电价如何影响美国住宅太阳能+储能的使用

Adoption of paired solar-plus-storage systems has accelerated in recent years, driven by both the demand for backup power and a desire to manage utility bills. Tradeoffs between those two uses can arise through the reserve setting on the battery storage system, which serves to maintain a minimum state of charge in case of a power interruption. Our paper applies an economic framework to evaluate this tradeoff in terms of changes in bill savings and customer reliability value across reserve levels, considering how those tradeoffs depend on the underlying electricity rate structure and levels. The analysis is based on a representative set of load profiles, solar profiles, tariff designs, and stochastic power interruption events across ten different regions in the United States. We find that the opportunity cost of holding storage capacity in reserve, in terms of foregone bill reductions, outweighs any gains in reliability value from mitigated power interruptions in the majority of customer situations. Higher storage reserve levels increase total customer value only in specific circumstances, such as for customers with inferior reliability (10x average interruptions), with a very high value of lost load ($50/kWh), and with tariff or interconnection rules that disallow grid charging. However, even this result is dampened when considering tariff designs with higher price differentials that increase the opportunity cost of holding storage in reserve (e.g. import/export or time-of-use rates). Allowing grid charging in tariffs essentially eliminates the necessity to hold any storage in reserve in all sensitivity cases explored.
近年来,由于对备用电源的需求和管理公用事业账单的愿望,太阳能+储能系统的采用加速了。这两种用途之间的权衡可以通过电池存储系统的备用设置来实现,该系统用于在电源中断的情况下保持最小的充电状态。我们的论文应用了一个经济框架来评估这种权衡,考虑到这些权衡是如何依赖于潜在的电价结构和水平的,在账单节省和客户可靠性价值方面的变化。该分析基于一组具有代表性的负荷概况、太阳能概况、电价设计和美国10个不同地区的随机电力中断事件。我们发现,在大多数客户情况下,保留存储容量的机会成本,就放弃的账单减少而言,超过了减轻电力中断带来的可靠性价值的任何收益。较高的存储储备水平仅在特定情况下才会增加总客户价值,例如对于可靠性较差(平均中断10倍)的客户,具有非常高的损失负载值(50美元/千瓦时),以及不允许电网收费的电价或互连规则。然而,当考虑到具有较高价差的关税设计时,即使这一结果也会受到抑制,这增加了储备储存的机会成本(例如进出口或使用时间比率)。允许电网收费基本上消除了在所有敏感情况下保留任何储备的必要性。

The rapid growth of electric vehicles (EVs) demands efficient, grid-friendly charging systems. This study introduces a dynamic pricing framework combining short-term demand forecasting and deep reinforcement learning. Using Adaptive Charging Network (ACN) data, XGBoost predicts charging demand accurately (R2 = 0.84, MAE = 0.45 kW). Compared to a uniform rate applied to all charging usage, set at 0.15 USD/kWh across all hours, with no adjustment for system demand conditions or time-of-day, the optimized strategy enhanced total daily revenue by 133 % and diminished load variance by 72.37 %. The PPO agent also surpassed traditional Time-of-Use and demand-based pricing models by 67–94 %, while ensuring pricing stability with a price standard deviation of 0.132 USD/kWh. The simulation results illustrate the framework's efficacy in facilitating off-peak charging and improving grid reliability.
电动汽车(ev)的快速增长需要高效、电网友好的充电系统。本研究引入了一个结合短期需求预测和深度强化学习的动态定价框架。XGBoost利用自适应充电网络(ACN)数据,准确预测充电需求(R2 = 0.84, MAE = 0.45 kW)。与适用于所有充电使用的统一费率(在所有时间内设置为0.15美元/千瓦时,不根据系统需求条件或一天中的时间进行调整)相比,优化后的策略使每日总收入增加了133%,负载差异减少了72.37%。PPO代理也比传统的基于使用时间和需求的定价模型高出67 - 94%,同时确保了价格的稳定性,价格标准差为0.132美元/千瓦时。仿真结果表明了该框架在促进非峰充电和提高电网可靠性方面的有效性。

The simulation results illustrate the framework's efficacy in facilitating off-peak charging and improving grid reliability.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"96 ","pages":"Article 102038"},"PeriodicalIF":4.4,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144907118","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}

This study examines the presence of abnormally low bids in public-private partnership (PPP) project tenders across Latin America. To this end, a representative database of PPP processes in Latin America was developed. Surprisingly, the findings indicate a notable absence of abnormally low bids. This result stands in stark contrast to recent studies. The analysis of 122 PPP projects spanning diverse countries and sectors provides a foundation for constructing a statistical test to identify abnormally low bids.
本研究考察了拉丁美洲公私合作(PPP)项目招标中存在的异常低标现象。为此目的,开发了一个具有代表性的拉丁美洲公私伙伴关系进程数据库。令人惊讶的是,调查结果显示,明显没有出现异常低的出价。这一结果与最近的研究结果形成鲜明对比。对跨越不同国家和行业的122个PPP项目的分析为构建统计检验以识别异常低的投标提供了基础。

Digital solutions in search of a problem? Balancing short-term and long-term needs in water utilities 数字解决方案在寻找问题?平衡水务公司的短期和长期需求

Digitalisation has gained interest in the broader water sector, with data-driven solutions seen as key to this development. Digital technologies are often portrayed as solutions to current and future challenges and potential applications have been identified across all areas of urban water management. However, their implementation in water utilities remains limited. This paper examines how the use of data-driven solutions aligns with and addresses the perceived needs of water utilities. It is based on an interview study with 23 key informants from Swedish water utilities involved in implementing and using data-driven solutions in urban water management. Our findings suggest that these solutions are not yet well-aligned with the technical and organisational structures of utilities. While they can address the long-term needs of water utilities with promises of improved efficiency and performance, they are less equipped to meet short-term needs which call for simple, immediate-impact solutions. Although implementing data-driven solutions should be justified by actual organisational needs, we must distinguish between the short-term and long-term needs of water utilities. Prioritising short-term needs may be more efficient in the short run but can be detrimental in the long run, which creates an ambidexterity dilemma for water utilities. Utilities should formulate digital vision or strategies that consider both the short-term and long-term needs of utilities to benefit fully from digitalisation.
数字化已经在更广泛的水务领域引起了人们的兴趣,数据驱动的解决方案被视为这一发展的关键。数字技术通常被描述为解决当前和未来挑战的解决方案,并已在城市水管理的所有领域确定了潜在的应用。然而,它们在水务公司的执行仍然有限。本文探讨了数据驱动解决方案的使用如何与水务公司的感知需求保持一致并解决这些需求。它基于对瑞典水务公司的23名关键信息提供者的访谈研究,这些信息提供者参与了城市水管理中数据驱动解决方案的实施和使用。我们的研究结果表明,这些解决方案还没有很好地与公用事业的技术和组织结构相一致。虽然它们可以通过承诺提高效率和绩效来解决水务公司的长期需求,但它们在满足短期需求方面的能力较弱,这些短期需求需要简单、立竿见影的解决方案。虽然实施数据驱动的解决方案应该由实际的组织需求来证明,但我们必须区分水务公司的短期和长期需求。优先考虑短期需求可能在短期内更有效,但从长远来看可能是有害的,这给水务公司造成了两面性的困境。公用事业公司应制订兼顾短期及长远需要的数码愿景或策略,以充分受惠于数码化。
