This article aims to identify the intangible aspects that impact companies operating in the electricity sector. The study was conducted through a literature review of intangible aspects and companies in the electricity sector. The main findings of the research are the identification of 20 intangible aspects within the electricity companies, the categorization and discussion of each intangible aspect based on the four perspectives of the Balanced Scorecard (BSC), and the analysis of the relationship between the intangibles, BSC perspectives, and life cycle stages of energy companies. The findings provide valuable insights for energy company managers to incorporate intangible asset management into their day-to-day activities and to focus on the most crucial intangible aspects depending on their business's current stage in the life cycle.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50181102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of these factors also influence the intention of current only EV-owners to adopt PV or not in the future.

Unexpected increases in demand for coal, driven by war in Europe, coupled with new and growing Asia-based investment in coal mines and power plants prove the need for novel coal transition pathways. At the same time, the UN aims to electrify communities with little or no access to clean and affordable energy. This work, in part, serves to support the UN 2030 Agenda for Sustainable Development. The 2030 Agenda is seventeen sustainable development goals (SDGs). The sum of the goals is about improving environments and communities. And for communities, goals focus on improving living and working conditions. SDG 7 concerns provisioning clean and affordable energy and technology. Trust structures, which provide sources of funding and governance systems, are an underutilized means of supporting coal transitions. Also, they could be equally effective if used to electrify communities with little or no access to electricity. A Trust providing a globalized \"social security\" solution can strengthen coal transitions. A Trust that speeds the deployment of electricity to areas with little or no access uses an old-line model. Early 20th century electric utilities developed using a \"virtuous circle\" transaction through which investment in communities and their economic development grew electricity sales. Two novel Trust models offered in this work overlap on coal transitions. Also, they offer pragmatic ways to help decarbonize the world. That is, the models may be applicable in other economic sectors. Using novel Trust models can improve the quality of human lives through clean energy transitions.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50181105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the system’s high degree of freedom, induced by a large number of switches, provides difficulties. In the past, central computation systems that needed extensive communication between the master and the slave module on each cell were presented as a solution for running such a system. However, because of the enormous number of slaves, the bus system created a bottleneck during operation. As an alternative to conventional multilevel inverter systems, which rely on a master–slave architecture for communication, decentralized controllers represent a feasible solution for communication capacity constraints. These controllers operate autonomously, depending on local measurements and decision-making. With this approach, it is possible to reduce the load on the bus system by approximately 90 percent and to enable a balanced state of charge throughout the system with an absolute maximum standard deviation of 1.1×10−5. This strategy results in a more reliable and versatile multilevel inverter system, while the load on the bus system is reduced and more precise switching instructions are enabled.","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90281548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper aims to improve the understanding of the opportunities and constraints of decarbonizing India’s electricity sector and adds to the growing body of literature by modelling the electricity sector in India with a dynamic optimization approach that assesses options for effective greenhouse reductions through carbon pricing. Attaining significant variable renewable energy penetration in India by 2050 is consistent with the lowest cost power generation options identified through our simulations, where solar and wind can provide 66 % of the electricity needs by 2050, even without a carbon price. With a carbon price of US$50/tCO2e, the simulations project that wind and power generation share in the electricity mix will rise to 81 %, leading to significant emission reductions. In this scenario, power sector emissions will be 164 million tCO2e by 2050, which is only about 14 % of the emissions levels in 2019. The analysis also indicates that fossil fuels remain part of India’s electricity mix in 2050, but their role and operation would dramatically change. When a carbon price of US$50/tCO2e is introduced, coal capacity remains valuable to fill demand when solar and wind are not available. This would require modifications in operation schedules and repurposing coal power plants for frequent ramping up and down.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50177200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To answer this question, we analyzed data from the Pennsylvania-New Jersey-Maryland (PJM) market (with relatively low, approximately 3% wind penetration) from 2016 to 2019 using quantile regression methods that provide a comprehensive picture of market conditions. Our findings demonstrate that the merit order effect exists for wind power supply expansion with unit revenue declines across all quantiles and generators. These declines occur consistently throughout market conditions but at different magnitudes. Each additional GWh of wind power is associated with a fall in wind revenue ranging from $0.01/MWh to $0.08/MWh. Wind power's cross-cannibalization effect also reduces gas and baseload capacity revenues across all quantiles, ranging from $0.02/MWh to $0.06/MWh per additional GWh of wind power. Interestingly, our results also reveal positive impacts of wind power supply on value factors (a measure of the energy's worth to the market) at low price market conditions, but negative impacts at high price conditions of the 95% and 99% quantiles. These findings confirm differential impacts of wind power across market conditions – more wind increases its worth at low market values but decreases its worth at high market values. Although the observed effects are exceedingly small, the findings of negative and unequal impacts on unit revenue in this research provide some insights and possible policy recommendations for energy market analysts, wind developers, and energy policymakers.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50177204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
