In 2023, solar PV accounted for roughly 75 % of renewable power capacity additions globally, and capacity is expected to grow 20-fold by 2050. However, the political ecologies of solar power are uneven. Throughout the value chain, there are numerous social and environmental injustices experienced by laborers and in communities that are converted to sacrifice zones for sustainable development. Despite being the world’s third largest emitter of greenhouse gases, India is developing solar infrastructures at a rapid pace to mitigate the climate crisis. Drawn from a rich collection of original data—household surveys, semi-structured interviews, focus group discussions and naturalistic observation across various sites—in this study, we investigate perceptions by laborers of the hidden injustices of solar energy at multiple nodes of the solar PV lifecycle or value chain: silica mining (Uttar Pradesh), solar panel manufacturing (Karnataka), solar park development (Rajasthan), solar park operation (Rajasthan), e-waste (Delhi) and recycling (Tamil Nadu). We conclude with novel findings and urgent recommendations for future policy and research on India’s solar PV value chain.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1040619024000617/pdfft?md5=038ea39ca23e3cd673aad5c2163f2456&pid=1-s2.0-S1040619024000617-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141952790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conversion from overhead to underground systems due to security and climate change factors will increase the risk of FCOs due to site conditions. The failure in collaboration by front-end planning (FEP) teams can increase risk of FCOs due to missing scopes, errors in design, lack of existing field condition evaluation, constraints on the project schedule, or unexpected field conditions, among other causes. This study involved development of a quality control process that enables members of the FEP team to vote their confidence levels about risk control of FCOs before proceeding to final design. The proposed process utilized Analytical Hierarchy Process (AHP) methodologies to distribute the weights of stakeholder votes based on responsibilities for each category of FCOs to obtain an integrated metric of FEP team confidence. Data from an operational electric power utility was used to provide a case scenario approach and to illustrate the method. Three actual projects were analyzed to assess how well the process would have worked for them. The novelty of the proposed model is to enhance the effectiveness of collaborative working relationships across teams during the FEP process and to provide a quality control metric to capture risk of FCOs in the early phase to minimize cost overruns in the project execution phase.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141961099","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 analyzes the economic and environmental impacts of this cross-border power grid interconnection and presents a comprehensive financial analysis of the project. We formulate a power system model that includes a planned submarine HVDC transmission line between two countries and study various scenarios by using hourly data. Our results demonstrate that the interconnection line operates with a remarkably high utilization rate, ranging from 98.90 % to 99.95 % across all analyzed scenarios. This high utilization rate suggests that the project holds significant economic potential, with estimated net present values ranging from $1,786 million to $3,019 million at a discount rate of 7 %. Furthermore, from the sensitivity analysis on carbon price, discount rate, and transmission capacity, we show how the financial outcome of the project is affected by the change in these parameters. Finally, we discuss the consequence of imposing an additional constraint on the carbon emission to our model and then, minimizing the overall carbon emissions subject to keeping the overall cost without the interconnection. In both variations, we show that the two countries can achieve their policy goals without increasing carbon emission.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141314715","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}

Despite numerous initiatives, 2.9 billion people, mostly from South Asia and Africa, are without access to clean cooking fuel. The current study uses Demographic and Household Survey (DHS) Data from 46 developing countries and employs probit regression and decision trees to examine access to clean cooking energy and its determinants. The result shows that clean cooking fuel usage is low in Sub-Saharan Africa and a few countries in Asia. The study also finds that education, wealth, urban residency, and gender are crucial determinants of clean cooking fuel usage. As is the case, global efforts to provide clean fuel access to all and achieve net zero carbon emission require large-scale investment; the clean energy transition policy requires accentuating the improvement of access through supplies and the enhancement of the education and income of the household, especially in rural areas.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141249482","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}

Facilitated by transmission planning, geographic and technological diversity of the generation fleet may provide a mitigation to capacity shortfalls. In this work, offshore wind (OSW) energy is sited in the areas off the West Coast between Coos Bay, Oregon, and Crescent City, California. Three generation and transmission scenarios are modeled within the Western Interconnection: (i) 3.4 gigawatts (GW) of installed OSW capacity connected to Southern Oregon through a High Voltage Alternating Current (HVAC) Radial Topology in 2030; (ii) 12.9 GW of installed OSW capacity connected to Washington, Oregon, and California through a High Voltage Direct Current (HVDC) Radial Topology post-2030, and (iii) the same 12.9 GW connected to the same locations through a Multi-terminal DC (MTDC) Backbone Topology post-2030. Zonal dispatch simulations assuming coincident wind, solar, and hydropower production and loads over 18 meteorological years, accounting for temperature-dependent equipment derating and forced outages, serve as inputs to the Associated System Capacity Contribution (ASCC) methodology. The capacity credit is 33%, 25% and 34% for the 2030 HVAC Radial Topology, 2030+ HVDC Radial Topology, and 2030+ MTDC Backbone Topology, respectively. Transmission design is shown to mitigate the typical erosion of marginal capacity contribution as more OSW is developed, underscoring the opportunity for grid modernization while decarbonizing the generation mix.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1040619024000423/pdfft?md5=3934a8bd352897e913d37ecf7bcb4f82&pid=1-s2.0-S1040619024000423-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141051010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We calculate the cost and effectiveness of four different clean energy procurement strategies: U.S.-wide annual energy matching, local annual energy matching, hourly energy matching, and carbon matching. Carbon matching requires balancing emissions attributable to electricity load with avoided emissions from clean energy procurement (calculated with locational marginal emission rates), while energy matching requires balancing load and clean energy generation on an annual or hourly timescale. We evaluated these strategies as pursued by large electricity consumers with two different load profiles located in five different U.S. regions which vary in regulatory structure. We find that carbon matching is the most cost-effective procurement strategy, with a cost between $4.7 and $7.6/MWh, and has the lowest carbon emissions abatement cost at $13/t CO<sub>2</sub> displaced. We find that annual energy matching costs range from $10/MWh to $32/MWh, and that it does not guarantee carbon neutrality. Hourly energy matching costs are higher, ranging from $68/MWh to $181/MWh, depending on region and load profile, and it is the least cost-effective strategy at carbon emissions reduction, with abatement costs ranging from $77/t CO<sub>2</sub> to $161/t CO<sub>2</sub>. These results suggest that targeting clean energy investment in regions where current renewable energy penetration is low and marginal emissions rates are high is the most effective way for individual actors to reduce Scope 2 carbon emissions and reach carbon neutrality.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1040619024000186/pdfft?md5=6d7eab82800dc497816a639a4bba4a80&pid=1-s2.0-S1040619024000186-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140160063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
