While scholars acknowledge the significant potential of the concept of motivation and make a clear distinction between it and intention, previous studies have primarily focused on residents' water-saving intentions and overlooked the pre-impact of water-saving motivation on water-saving behavior. To investigate the psychological determinants of RWB, this study applied the Model of Goal-Directed Behavior to examine the interplay among constructs, including motivation, intention, and actual water-saving practices. Adhering to stratified sampling principles, a hybrid sampling approach integrating random and snowball methods was utilized to gather data from 1184 questionnaires. The collected dataset underwent rigorous analysis using structural equation modeling to explore the theoretical relationships. Results reveal that subjective norms, anticipation, and cognition significantly enhance residents’ motivation to conserve water, whereas attitude exhibits no significant effect. Furthermore, motivation serves as a pivotal antecedent of both water-saving intention and behavior. Additionally, past behavior frequency and perceived behavioral control positively moderate the intention-behavior relationship, reinforcing the translation of intention into action. This study advances theoretical understanding of the psychological mechanisms underlying water conservation and offers practical insights for fostering sustainable behaviors across diverse sociocultural settings.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"96 ","pages":"Article 102031"},"PeriodicalIF":4.4,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144852125","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}

The design provides a market-based solution for distribution system operators (DSOs) to address near-real-time grid issues. The grid segmentation computes the virtual buses that represent each zone and the sensitivity indices that approximate the impact of activating active power flexibility in the buses within the zone. This approach allows DSOs to manage and publish their flexibility needs per zone and enables aggregators to offer flexibility by optimizing their resource portfolios per zone. The simulation outcomes allow for the assessment of market performance according to the number of zones computed and show that addressing overloading and voltage control through zonal approaches can be cost-effective and counterbalance minor errors compared to node-based approaches.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"96 ","pages":"Article 102029"},"PeriodicalIF":4.4,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144852124","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}

We examine water consumption patterns in Hyderabad, India, with a focus on seasonal and spatial variations in daily per capita water consumption. The study employs one-sample t-tests and Classification and Regression Trees (CART) to investigate water consumption levels. A primary survey of 440 households was conducted in Hyderabad, divided into 31 circles. The perceived water usage data were collected from households to study consumption patterns. The study finds that the Service Level Benchmark (SLB) of 135 liters per capita per day (LPCD) for Indian cities corresponds to annual and winter averages at the household level. Significant variation from 135 LPCD was observed during the summer and rainy seasons in the surveyed households. Household characteristics, building characteristics, water sources, supply characteristics, coping mechanisms, appliances, and consumer behavior impact water consumption in households. The study highlights the need to consider seasonal demands and spatial scales (household, circle, and city levels) for effective water management. The findings indicate that the SLB of 135 LPCD corresponds to the water demands at larger spatial scales, such as the city and the circle. However, it has limited relevance at smaller spatial scales, such as the household level. The study helps to understand how per capita water consumption varies across seasons and spatial scales in an Indian city. The study of these spatial and seasonal consumption variations helps in the effective planning and implementation of water supply projects.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"96 ","pages":"Article 102017"},"PeriodicalIF":4.4,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144772247","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 develops a Cross-Spatial Vulnerability Model (CSVM) to analyse ALPF risks. It combines cascading risk and vulnerability theory with the bow-tie model, forming the basis of a Bayesian network for three ALPF cases in the China scenario, including summer heat and drought, winter cold waves, and coal price fluctuations. The analysis models complete Bayesian networks from official news, policy texts, and expert opinion sources, with three key findings. First, ALPFs can disproportionately impact economic stability, social stability, public health, and safety, with the probability of severe consequences being non-linearly related to the likelihood of ALPF events. Second, effective risk response to ALPFs requires focused attention on several key scenarios, such as delays in emergency response, outdated grid technologies, and restrictions on residential electricity consumption. Third, engineering and non-engineering measures should be integrated, with priority given to ensuring the proper functioning of social and livelihood systems. Unlike previous studies, we focus on the specificity of ALPF events, with a greater emphasis on a case-driven approach, shifting from the engineering and technical tendencies of previous studies to a comprehensive dimension. More consideration is given to the dynamic nature of risk.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"96 ","pages":"Article 102011"},"PeriodicalIF":4.4,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144721702","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}

In our article, we analyze how RECs enhance cooperation in ecological transition with a game-theoretic approach.

A REC creates incentives for cooperation through three primary revenue sources: cost savings from self-produced and consumed energy, surplus energy sales, and government incentives.
