Urban growth trends and increasing competition for limited natural water resources among different uses and localities have prompted governments to resort to intensive desalination. Taking the case of Algiers Province, this paper examines the possibilities of supporting urban growth through a sustainable urban water intervention strategy in the face of drought threats. To this end, it puts forward an original scenario selection method based on targeted water resource carrying capacity (WRCC) and combined multi-criteria decision-making (MCDM) techniques. The research novelty lies in the fact that scenarios are developed by cross-referencing supply and demand scenarios in response to a predefined WRCC. To achieve this, we adopt a scenario approach that focuses on improving the existing water system and adapting it to anticipated growth and drought trends while reducing dependence on conventional water, which is subject to disputes between different uses and localities. Finally, the sustainability assessment of scenarios relies on the use of hybrid MCDM methods, in which Game theory is employed to combine criteria weights. The results indicate that intensive desalination is not a sustainable option and that reducing demand, along with the use of recycled water, can achieve a balance between supply and demand, supporting growth while maintaining efficient management of water resources. The proposed model can help officials and decision-makers plan a sustainable water strategy for drought-prone areas.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"96 ","pages":"Article 101987"},"PeriodicalIF":3.8,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144297506","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}

As the only technology currently capable of achieving large-scale decarbonization of fossil fuels, carbon capture and storage (CCS) technology is essential, especially for China, which heavily relies on coal-fired power generation. This study proposes a novel method for optimizing the network of coal-fired power plants equipped with carbon capture and storage (CCS) technology. To address the needs of China's transition strategy and industrial policy, we investigate the deployment trajectories of coal-fired power plants with CCS under different carbon quota constraints and various coal-fired power development scenarios. We found that, depending on future transition scenarios, the deployment scale of CCS coal-fired power plants ranges from 33.26 GW to 406.4 GW. Specifically, around 30 GW–60 GW will need to be deployed by 2035, with an additional 70 GW–150 GW required by 2050. Failure to accelerate early deployment could significantly increase the pressure on the coal power sector to reduce emissions and hinder the overall carbon reduction process in China. The coal-fired units needing retrofitting are primarily concentrated in the 'Three North' regions, and with larger deployment scales, this will gradually spread to Central and Eastern China. Inner Mongolia, Shandong, and Xinjiang will bear the highest capture cost expenditures. The total length of CO<sub>2</sub> transportation pipelines may reach up to 25 thousand km, with many pipelines requiring cross-provincial or cross-regional construction. Lastly, based on the findings of this study, development suggestions are proposed for advancing coal power CCS.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"96 ","pages":"Article 101992"},"PeriodicalIF":3.8,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144271160","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 paper proposes a strategic reserve selection framework combining Monte Carlo simulation and mixed-integer linear programming to identify optimal reserve units by minimizing the cost per unit reduction in expected energy not served, thereby quantifying the economic efficiency of converting units of different capacities such as 300 MW, 600 MW, and 1000 MW and with service ages ranging from 1 to 30 years into strategic reserves. Simulation results for a representative region in East China indicate that converting 1000 MW units at around 20 years of service age yields the best economic benefits. With a renewable penetration rate of 30 %, the minimum strategic reserve cost of a 1000 MW unit is 13,780 CNY/MWh, compared to 15,630 and 26,120 CNY/MWh for 600 MW and 300 MW units, respectively. When the penetration rate increases to 50 %, the minimum cost of 1000 MW, 600 MW, and 300 MW units is reduced by 80.19 %, 77.42 %, and 76.03 %, respectively. Sensitivity analysis shows that increasing reserve margin raises costs, while higher renewable penetration advances the optimal conversion age. Large-capacity units consistently offer superior reduction of expected energy not served, with up to 64.65 % reliability improvement. These findings provide empirical guidance for policymakers in coal-dependent countries, highlighting the cost-effectiveness of prioritizing large, moderately aged units for reserve conversion to balance reliability and economic objectives.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"96 ","pages":"Article 101991"},"PeriodicalIF":3.8,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144263120","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 shift was further evidenced by the entry of the fourth operator (<em>Wom</em>) and its aggressive strategy.

Conventional models used in REC studies generally assume monetary energy transactions, where those with deficit generation financially compensate members with surplus energy. This study addresses a gap in the literature by proposing a novel energy management model for a Portuguese REC, optimizing socially conscious energy trading without internal monetary compensation. A community of 10 households with photovoltaic generation, with and without battery storage, and a tertiary building (TB) is analyzed over a 25-year investment horizon, incorporating realistic electricity prices, taxes, and the evolution of consumption and generation. The study evaluates three key aspects of REC: technical performance, economic viability, and environmental impact. Results show that prosumers can achieve € 2523 annually from selling surplus electricity to the TB rather than to the grid. A self-sufficiency of 80 % and a reduction in CO2 emissions can be achieved in the REC scenario with the highest battery capacity. Findings reveal that investing in a REC is more profitable than individual self-consumption or non-investment, with potential net present values reaching €14,806 and internal rates of return of 24 %. A fairness index calculation shows that the new benefit allocation model outperforms existing ones in ensuring equity among members. This simulation study provides valuable insights for prosumers and policymakers, demonstrating the economic and environmental advantages of REC in accelerating the clean energy transition.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"96 ","pages":"Article 101986"},"PeriodicalIF":3.8,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144195152","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}
