This study examines how five European countries from different synchronous areas address these challenges, focusing on the market-based procurement of inertia-related services. We provide a theoretical background on why stability service markets are challenging to design due to the interplay between different services and their costs. Further, we use a theoretical market framework to analyze the market design elements and to see how aligned they are with the evolving needs of the power system. Our findings stress the importance of investment incentives for low-carbon technologies and proactive market designs to meet evolving stability needs, offering guidance for power systems integrating a high share of renewables.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"95 ","pages":"Article 101938"},"PeriodicalIF":3.8,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143792361","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}

The analysis applies a computable general equilibrium-microsimulation model to analyse the economy-wide and distributional impacts of the increase in electricity price in an emerging economy with limited electricity supply. A key benefit of this model is that it addresses the distributional and poverty impacts related to the change in electricity prices, which have yet to be covered in previous studies. The paper simulates an actual price increase experienced in the economy and an increase linked to inflation. While the macro results show a negative impact on the economy in terms of a decrease in GDP, an increase in prices and an increase in unemployment, the micro results indicate that poverty declines as measured by the rate and poverty incidence curves. Several policy implications arise from these findings, such as considering more progressive taxation policies to counteract the slight increase in inequality resulting from higher electricity prices.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"95 ","pages":"Article 101936"},"PeriodicalIF":3.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143747123","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}
