Electric power can be troublesome to appraise because consumption is not the customer’s main goal, but rather a means to achieve a desired good or service that often has unquantifiable personal value. This paper proposes a market-based household production method that quantifies the customer electric service interruption costs in the residential sector. Because an individual’s personal time is necessary to replace services owing to the lack of electric power, we propose a method that estimates the weighted market cost of a person’s time in accordance with their occupation to better calculate customer outage costs. We also present a macroeconomic production method to estimate losses in the residential sector. Finally, we propose a method for calculating the true costs of electric services by factoring the outage costs with the electrical utility rate to be analyzed using reliability metrics. The proposed approach facilitates a closer estimation of the low-bound true costs of utility-supplied electrical services for consumers who have not taken mitigation measures, serving as a warning for energy regulators to impose corrective actions or appropriate penalties on unreliable utilities and/or as an indicator for customers to invest in alternative energy sources.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140052083","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}

Obstacles lie in the way of such a vision, however. Chief among them, paradoxically, is the administrative system that has evolved since the late 1990 s to promote regional electricity markets. That system abstracts from investment risk and the nation’s uneven geography of renewable resources. It lodges a kind of monopoly planning and scheduling power in a small group of bureaucratic centralized system operators that mimics a command economy in their own distinct regions, not the kind of market economy that has traditionally driven investment in US interstate energy infrastructure. And yet, in dealing with the vexing transmission constraints faced by the renewable generating sector (the “queue”), the Federal Energy Regulatory Commission (FERC) continues to pursue ever greater authority for those regional transmission organizations (RTOs). Such FERC action regarding its RTOs in 2022–23 represents a highly evident case of <em>path dependency</em>—a problem—that state or federal policy makers wishing to speed the entry of large-scale renewable generation, and complementary storage technologies, will have find a way either to confront directly or to work around.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140016317","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}

Using a capacity expansion and dispatch model of the Northeastern North American power system, we draw lessons from the interconnection potential of Quebec’s large existing hydropower capacities. We find that reservoir-transmission coupling significantly decreases the cost of decarbonization, even when short-term storage costs are low, because it is used for both daily and seasonal balancing. Conversely, the value of short-term storage is compromised by the availability of reservoir-transmission coupling, even assuming high investment costs for transmission. We also describe the regional distribution of costs and benefits of storage and transmission and discuss implications for regional cooperation.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1040619024000101/pdfft?md5=db9e24f8c07742257154a6628a3fa116&pid=1-s2.0-S1040619024000101-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140062961","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}

Under international humanitarian law, belligerents may not intentionally target civilians or installations that are indispensable to the survival of the civilian population. While collateral harm to civilians and civilian infrastructure may occur, international humanitarian law prohibits attacks that may be expected to cause incidental loss of civilian life, injury to civilians, damage to civilian objects, or a combination thereof which would be excessive in relation to the concrete and direct military advantage anticipated. In practice, these principles have not always been honored or enforced. State and non-state actors have deliberately targeted civilians and/or disregarded civilian impacts, often for the purpose of pressuring political leaders to capitulate. The increasing occurrence and severity of harm to civilians and civilian infrastructure in modern conflicts calls into question the continuing relevance of what were once viewed as fundamental protections. In this paper, we present a case study involving Russia’s 2022–23 attacks on Ukraine’s electric power infrastructure, which left millions of civilians without heat, water, or other basic services for extended periods in harsh winter conditions. Considering the scope, scale, and long-term impacts of these attacks, we conclude that Russia violated international law. We also suggest that a new international protocol may be necessary in order to more effectively deter and punish attacks on civilian infrastructure in future armed conflicts and military occupations.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139936715","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 study examines the socio-political barriers that hinder the expansion of the renewable energy industry in India, a nation facing the dual challenges of rapid economic growth and environmental preservation. Amidst increasing global apprehensions regarding the environment, this study employs a comprehensive analysis encompassing ANOVA, correlation, and regression to identify crucial aspects influencing the advancement of renewable energy in India. While previous studies have recognized financial limitations such as brief loan durations and significant capital expenses as substantial obstacles, our research explores the intricate interaction of several elements in greater detail. The key findings reveal substantial variations across the groups examined, providing insight into the differing degrees of awareness and concern surrounding renewable energy. Remarkably, limited connections arise between crucial factors such as awareness of renewable energy, care for the environment, and government energy policy. The regression analysis highlights the insufficiency of the variable \"Development of renewable energy in India\" in accurately predicting the dependent variable, thus indicating the presence of other relevant factors. India's present renewable energy capacity is only 18%, with hydro energy contributing 14%. Our research highlights the need for specific actions to address this issue. The study continues by recommending incorporating scholarly knowledge into policy development to encourage investor attraction and promote the widespread acceptance of cleaner and renewable energy solutions at both national and international levels.
