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.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"96 ","pages":"Article 102035"},"PeriodicalIF":4.4,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144912511","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}

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.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"96 ","pages":"Article 102036"},"PeriodicalIF":4.4,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144903862","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}

Rooftop photovoltaic (PV) systems have emerged as a promising solution, aligning with sustainability, decentralisation, and local energy production while efficiently using built spaces. Despite their potential, rooftop PV systems are still unevenly adopted due to technical and economic barriers. A lack of consistent data limits the ability to track adoption and support energy transition planning. This study focuses on Tarragona province (Spain) and assesses the solar PV potential of public and private buildings, including town halls, schools, libraries, and residential properties. Using GIS-based modelling and high-resolution geospatial data, including LiDAR-derived elevation models and cadastral records, we estimate that 38.72% of rooftops in the province meet suitable technical conditions for PV installation under a conservative scenario. A key contribution is the creation of a geolocated database of 18,577 rooftop PV installations through detailed photointerpretation, enabling spatial assessment of where systems have been deployed and how adoption varies by building type. Statistical analysis reveals contrasts in adoption, with residential buildings showing higher uptake, while public buildings adopted PV later. Results confirm that adoption is shaped by technical potential and sector-specific policy barriers. Findings suggest public buildings could foster broader PV uptake, leveraging peer effects and targeted incentives. This study highlights the need for accurate, publicly accessible PV installation databases to support energy planning, especially in urban and mixed-use areas. By clarifying PV adoption dynamics, this research supports informed policymaking for a more equitable, effective energy transition.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"96 ","pages":"Article 102025"},"PeriodicalIF":4.4,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144866830","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}

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 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}
