Increased net-load variability places greater demands on the electrical grid, whose development pace is targeted as a bottleneck to achieving a decarbonized energy system. Policymakers and regulators want to mitigate the limitations in grid development by compelling distribution system operators (DSO) to consider the locally available distributed flexibility resources (DFR) as virtual capacity providers when planning the expansion of the distribution networks' physical assets. This analysis focuses on flexibility from the DSO perspective, trying to set an end-to-end epistemological common ground for policymakers, regulators and DSOs. It analyses the current public policy framework, setting the conventional planning objectives as a basis to understand the flexibility boundaries, and proposes an optimal capacity planning methodology where flexibility is taken as a new decision dimension, whose value can be obtained using a counterfactual approach, to be used in flexibility markets.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"93 ","pages":"Article 101892"},"PeriodicalIF":3.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143099105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This analysis uses a split-sample design to examine whether business enterprises in Addis Ababa, Ethiopia, have different valuations for improved power supply reliability under two payment vehicles (electricity bill increases and tax revenue allocation). Results show that these businesses are willing to pay (WTP) an average of US$33 per year for a 1-h monthly reduction in outages and US$24 per year for one less outage per month. These amounts represent approximately 11% and 8% of the typical annual electricity bill of 10,615 Birr (US$295), respectively, highlighting that businesses place substantial value on electricity reliability. We find no significant differences in preferences or WTP estimates between the bill and tax payment vehicle sub-samples, suggesting that tax payment vehicles are as credible as bill increases in stated preference studies and that multiple mechanisms for financing power reliability investments may be feasible in practice.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"93 ","pages":"Article 101893"},"PeriodicalIF":3.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143099106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the recent introduction of time-of-use (TOU) tariffs and policies addressing the “duck curve” effect, the research focuses on optimizing PV system sizing across different regulatory frameworks. A detailed techno-economic analysis evaluates these scenarios based on energy production, cost savings, payback periods, and energy self-sufficiency. The findings indicate that net metering and net billing offer the highest cost savings and the shortest payback periods (∼3 years). While the zero-export strategy with battery storage enhances energy self-sufficiency by up to 70%, it requires a higher upfront investment. The sell-all-buy-all scenario supports larger system sizes, achieving a low levelized cost of electricity (0.0696 USD/kWh) and a net present value of 619 USD. Additionally, the study identifies a critical feed-in tariff threshold of 0.055 USD/kWh, at which net billing becomes as financially attractive as net metering. These insights offer valuable recommendations for policymakers to optimize net billing rates and TOU tariffs, promoting the expansion of Jordan's renewable energy sector.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"93 ","pages":"Article 101894"},"PeriodicalIF":3.8,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143099104","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 this work, we study the reduction of usable capacity as a congestion management measure in a local flexibility market context. Using an extensive two-year residential charging dataset from Denmark, we highlight the problems caused by the almost 50% non-utilized capacity on an aggregated level of household chargers. We discuss and address various market design challenges and the implications of free excess capacity by treating aggregated capacity as a divisible good that can be traded between a distribution system operator (DSO) and flexibility service providers. The use of <em>capacity blocks</em> streamlines service delivery and overcomes many of the challenges of using explicit services. Finally, we show empirically that a simple, uniform pricing, two-stage auction significantly reduces DSO payments and mitigates the issue of excessive profit margins compared to a single-stage auction.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"93 ","pages":"Article 101889"},"PeriodicalIF":3.8,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143099103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Numerous initiatives have been made to craft pricing mechanisms on TES as incentives to leverage resource flexibility and contribute to improving technical and economic indexes. Nevertheless, comparing these pricing mechanisms is challenging due to the fluctuating market conditions and diverse TES configurations. This research compares the impact of the Distribution Locational Marginal Pricing (DLMP) and Cost-Sharing (CS) pricing mechanisms on TES fairness, economic efficiency, and voltage quality under identical market conditions. In addition, a unified index is proposed to compile market metrics and facilitate Distribution System Operator (DSO) decisions on pricing according to weighted objectives. Accordingly, this research contributes valuable insights that promote TES expansion and better management for DSOs and market regulators. This paper uses a transactive forward market on the IEEE-33 bus test system as a case study. The results show that CS pricing yields complete price fairness. In contrast, the DLMP forgo fairness for the sake of economic efficiency. Here, the unified index reveals that CS pricing is preferable when the DSO weights equally fairness and efficiency, even though DLMP demonstrates a superior voltage quality index in the case study. The developed comparison framework is general to all pricing mechanisms as it simplifies the interactions between the DSO and the consumers through price and energy demand signals.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"93 ","pages":"Article 101890"},"PeriodicalIF":3.8,"publicationDate":"2025-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143164058","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}
