Building on transaction cost economics, investment theory, and the property-rights approach, a real-options model is developed to evaluate the economically admissible level of transaction costs under different opportunity-cost assumptions. The model integrates asset structures, liquidity buffers, and operational surpluses, and is applied to Polish data on RES auctions, virtual prosumption, and the balance sheets of benchmark energy firms. Results show that when opportunity costs are charged on the total asset base, acceptable transaction costs are uniformly negative across all cases, leaving no room for rigid institutional commitments. Only when opportunity costs are assessed relative to equity do temporary, narrow windows of tolerance emerge, especially in early auction years or in firms with atypical equity structures. These findings explain the weak adherence to energy clusters: investors prioritize flexibility and liquidity, while rigid contractual schemes raise transaction costs beyond tolerable thresholds. The study concludes that institutional designs for energy communities should reduce sunk costs, enhance flexibility, and align incentives with investors' liquidity profiles rather than relying solely on price-based mechanisms.</div></div>","PeriodicalId":11672,"journal":{"name":"Energy Policy","volume":"208 ","pages":"Article 114897"},"PeriodicalIF":9.2,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145156056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

DECAL has sufficient detail to model true net-zero pathways and reveal fine-grain technology insights.

Drawing on the middle-out perspective, it explores the agency and capacity of developers over time, offering insight into how motivations, priorities, and capabilities affect MEPR compliance. Energy performance data are combined with two rounds of developer interviews (2012 and 2021/2022) and planning documents to compare calculated and actual performance and to understand developer perspectives.
