Since MMDG supplies load directly at the distribution level, it reduces the net demand visible to the transmission grid. This thread is reshaping the national net-load curve by deepening the midday valley and steepening the evening ramp that centrally dispatched resources must supply. Although the duck curve phenomenon and its curtailment implications have been widely studied internationally, quantitative evidence for hydro-dominated systems remains limited. In this context, the present study applies a data-driven analysis of hourly operational data from 2024 to evaluate how MMDG growth affects net-load variability, modifies ramping behavior, and influences curtailment exposure in the Brazilian National Interconnected System (SIN). To this end, the analysis addresses two guiding questions: (i) how the expansion of MMDG reshapes the aggregated load curve and alters intraday variability, and (ii) how its production profile relates to curtailment events classified as energy imbalance (ENE) in centralized wind and solar plants. By examining these aspects together, the study provides system-level evidence particularly relevant to hydro-based electricity systems undergoing rapid distributed PV expansion. The empirical results show that MMDG accentuates midday net-load valleys, particularly on weekends, with the lowest values occurring on Sundays, approaching 50,000 MW, followed by evening recoveries exceeding 25,000 MW and extreme short-term ramp rates approaching 10,000 MW per hour. Flexibility Factor indicators range from 0.59 to 0.71, indicating heightened short-term operational stress. At the same time, ENE curtailment intensifies during hours of high distributed output, presenting moderate positive correlations (<em>ρ</em> ≈ 0.37–0.49, <em>p</em> < 0.01). Taken together, these findings demonstrate that the continued growth of MMDG amplifies intraday variability and curtailment exposure in Brazil's hydro-dominated system, thereby underscoring the need for strengthened coordination between transmission and distribution operators.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"99 ","pages":"Article 102148"},"PeriodicalIF":4.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145976918","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}

DSF could play a crucial role in maintaining grid stability, integrating variable renewable energy sources, and reducing infrastructure costs. The prevailing framework for fostering DSF overwhelmingly relies on price signals and assumes that consumers are rational, price-responsive agents who are both willing and able to optimize electricity use. Empirical evidence suggests that this approach has yielded limited results. The proposed model emphasizes centralized flexibility management, regulatory mandates, and automation to ensure reliability and scalability. Central to this model is the establishment of a Flexibility Coordinator responsible for two primary tasks: coordination—identifying system-wide grid needs, mapping users’ flexibility potential, and aligning these to generate an effective set of target measures; and execution—applying a set of targeted regulatory measures focused on mandating and “embedding” flexibility across the grid while minimizing user disruption and safeguarding comfort and preferences. These measures could include mandating automated demand-response functionality for residential heat pumps and EV chargers, requiring supermarkets to couple cooling loads with automated controls, and enforcing waste heat recovery in industrial processes. By adopting a more assertive and systematic approach, a range of flexibility measures—potentially imperceptible to users—can be effectively implemented, creating a more reliable, adaptable, and scalable DSF model that is essential for a successful energy transition.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"99 ","pages":"Article 102137"},"PeriodicalIF":4.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145790567","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}
