The annual estimated investment is about USD 70 billion to reach the target of 100 % electrification by 2030 and achieve sustainable energy. Considering the constant constraints on the government's budget, the need for private investments to meet this target is evident in addressing the perceived high investment risks in rural electrification in Rwanda. This paper examines whether diversification through geographical distance and energy source/technology in a portfolio of mini-grids for power can reduce investment risks and increase capital availability and volumes. Quantitative estimation of the cost of financing and derisking effects of the private investment strategies for a hypothetical portfolio in Rwanda was applied as a method of analysis. Findings show that, theoretically, private investment in the energy mix can help lower the cost of capital. A rise in the amount of capital available for Rwanda's rural electrification could result from a fall in the cost of capital, which has a statistically significant link with capital. We highlight the implications of this study for policy and practice and conclude by identifying limitations and providing avenues for further research.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"95 ","pages":"Article 101948"},"PeriodicalIF":3.8,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143859610","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}

Furthermore, 26.2 GW of PV power generation systems are expected to be newly installed by 2030, which indicates there will be several new entrants into the PV power generation market in the near future. We applied data envelopment analysis and the metafrontier global Malmquist index (MGMI) to Japan's PV power generation plant data (2016–2020) to investigate the static power generation efficiency and its growth considering new entrants and regional heterogeneity. The results demonstrated that the western region showed the highest static efficiency. Conversely, the eastern region experienced the largest increase in MGMI, with an average annual growth rate of 1.2 %. The decomposition analysis results of MGMI reveal that technological innovation within the same region is the primary driver of the growth in MGMI in all regions, while the catch-up effect has a negative effect. These results indicate that while advanced PV power plants in all regions contribute to advancing frontier technologies, others are insufficiently catching up. Policymakers should, therefore, encourage technology spillover between innovative power plants and others to promote the catch-up effect. We additionally identified innovative power plants that promote frontier technology, and the results demonstrated that plants that started operation before 2016 primarily contributed to technological innovation, indicating that the learning-by-doing effect of existing plants and the availability of favorable sites have a greater impact on power generation efficiency than introducing advanced facilities.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"95 ","pages":"Article 101945"},"PeriodicalIF":3.8,"publicationDate":"2025-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143848076","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 strategy poses key challenges, including understanding how different LESS technologies compare in terms of both economic benefits and environmental impact, as well as analysing the complex interactions within and between markets when storage is deployed. To help shed light on these aspects, we investigate how LESS location, rated power, duration, and technology can affect welfare and carbon emissions in the Italian electricity system by modelling the day-ahead and the ancillary services markets. We considered lithium-ion batteries, pumped-storage hydro, and vanadium redox flow batteries. The results show that deploying LESS is always beneficial in the day-ahead market, but ancillary services costs can increase due to spillover effects because these markets run sequentially. Lithium-ion is the technology that yields the best social welfare increase. Location, rated power, and duration significantly impact carbon emissions, with changes ranging from −260 kgCO2 to 190 kgCO2 per MWh traded. These results suggest that LESS can help increase welfare and induce unintended consequences, such as spillovers across markets with a mixed effect on emissions.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"95 ","pages":"Article 101937"},"PeriodicalIF":3.8,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143839307","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}
