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.

Our study fills a gap in the literature by offering a formal strategic model that explains both the coordination mechanisms enabling successful REC formation and the bargaining processes that determine revenue distribution.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"96 ","pages":"Article 102006"},"PeriodicalIF":3.8,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144655949","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 structure has historically ensured energy security and ensured coordination of hydrothermal resources. However, as the electricity matrix evolves with increasing shares of variable renewable energy, new challenges emerge concerning operational flexibility, system balancing, and market efficiency. Unlike deregulated markets where short-term price signals and locational pricing mechanisms guide dispatch decisions, the Brazilian model remains heavily cost-driven and centrally coordinated, raising discussions about its long-term adaptability. This paper provides a comprehensive overview of the Brazilian electricity sector, focusing on dispatch optimization, system operation, and long-term planning frameworks as structured in 2025. The research condenses key aspects of the NEWAVE, DECOMP, and DESSEM models, detailing their role in hydrothermal scheduling and their limitations in accommodating a more dynamic and decentralized energy landscape. By consolidating fragmented discussions from the existing literature, this work bridges the knowledge gap on how Brazil's market operates and compares to more advanced market designs. Incorporating lessons learned from international experiences, the study aims to identify market mechanisms and regulatory frameworks that can enhance Brazil's pricing models, flexibility resources, and real-time system coordination. Ultimately, this study serves as a reference for the international energy community, presenting a comprehensive and structured analysis of the Brazilian electricity market. It explores potential avenues for modernization, informed by global best practices, the evolution of contemporary market paradigms, and the ongoing energy transition.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"96 ","pages":"Article 102007"},"PeriodicalIF":3.8,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144596641","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}

With 87 % of homes lacking access to clean electricity, solar photovoltaic (PV) systems present a viable alternative. Beyond providing energy security, solar PV technology mitigates climate change by reducing reliance on fossil fuels. While PV systems have been successfully adopted in many countries, Pakistan's domestic solar potential remains largely untapped due to cost constraints. This study examines the adoption of solar PV systems among households in Pakistan's twin cities, considering socioeconomic and demographic factors. Although solar PV technology offers advantages over traditional power generation, several obstacles have hindered widespread adoption, with cost emerging as the primary barrier. The lack of sufficient government support has also slowed adoption. Other challenges include low household income, location of the house, and homeownership status. However, environmental concerns and the availability of solar equipment in local markets have encouraged some households to invest in solar PV systems. A three-stage random sample approach was used to select 501 twin-city families. Only 25 % of households have solar photovoltaic (PV) systems, despite 77 % using electrical backups during power outages. According to the Double Hurdle (DH) regression model, households with more educated heads are more likely to install solar PV systems. Homeownership and peer influence also boost adoption rates. Many households avoid switching due to the expense of upfront expenditures and unsuitable dwelling locations, such as apartments. Tax incentives and subsidies for home solar systems could boost adoption, help stabilize power supply, and mitigate climate change.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"96 ","pages":"Article 102005"},"PeriodicalIF":3.8,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144588301","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}
