This study investigates the extent to which the concept of energy resilience is integrated into energy policy scholarship and proposes future research agenda to strengthen engagement with energy resilience in energy policy making. Our study shows that energy resilience is absent in energy policy scholarship, or framed the other way round, energy policy scholarship is absent in the discussion of energy resilience topic. We used bibliometric analysis of literature across Scopus and ProQuest databases and applied keyword co-occurrence mapping and journal-keyword analysis techniques to assess how themes of energy resilience intersect with “community,” “disaster,” and “policy.” Our analysis reveals that energy resilience is predominantly framed within technical, systemic and infrastructural contexts, with limited interdisciplinary attention to its socio-economic, governance, and equity dimensions. Notably, resilience-related terms are underrepresented in leading policy journals, suggesting a disconnect between energy resilience as a concept and energy policy scholarship. We argue that advancing energy resilience as a structured policy agenda requires a holistic framework that integrates technical reliability with community-level resilience, institutional capacity, and justice considerations. This research provides empirical evidence of the thematic silos in the energy policy literature and offers a roadmap for incorporating energy resilience more substantively into energy policy design, implementation, and evaluation.

本研究调查了能源弹性概念在多大程度上融入了能源政策学术，并提出了未来的研究议程，以加强能源弹性在能源政策制定中的参与。我们的研究表明，能源弹性在能源政策研究中缺失，或者反过来说，能源政策研究在能源弹性主题的讨论中缺失。我们对Scopus和ProQuest数据库中的文献进行了文献计量分析，并应用关键词共现映射和期刊关键词分析技术来评估能源弹性主题与“社区”、“灾难”和“政策”之间的交叉关系。我们的分析表明，能源弹性主要是在技术、系统和基础设施背景下构建的，对其社会经济、治理和公平维度的跨学科关注有限。值得注意的是，与弹性相关的术语在主要政策期刊中的代表性不足，这表明能源弹性作为一个概念与能源政策学术之间存在脱节。我们认为，将能源弹性作为一项结构性政策议程推进，需要一个整体框架，将技术可靠性与社区层面的弹性、机构能力和司法考虑相结合。本研究为能源政策文献中的主题筒仓提供了经验证据，并为将能源弹性更实质性地纳入能源政策的设计、实施和评估提供了路线图。

To fully decarbonize electricity generation, there is a need to meet electricity demand at times of low solar and wind availability. Natural gas combined cycle (NGCC) generation with carbon capture and storage (CCS) that reduces power plant CO₂ emissions is one technology proposed for this purpose. However, CCS does not capture all power plant CO₂ emissions and does not address methane emissions that occur upstream of NGCC power plants. Furthermore, the cost of CCS is often not evaluated at capacity factors that represent likely use cases of NGCC power plants in low-carbon grids. Therefore, we evaluate the effect of uncaptured fugitive methane emissions on the climate benefits of CCS and the role of NGCC capacity factors on the economics of CCS. Accounting for time- and region-dependent methane leakage, we find that CCS reduces system-level greenhouse gas emissions between 21 % and 88 %, with remaining climate impacts being primarily due to uncaptured methane emissions. At average United States methane leakage rates of 2.95 %, CCS reduces system-level greenhouse gas emissions by 47–71 %. In addition, we estimate that CCS-related capital and operating expenditures only make CCS cost-effective at high capacity factors and in the presence of financial supports such as the California cap-and-trade program and United States 45Q tax credits. These findings highlight significant technical and economic challenges of using NGCC with CCS to achieve full grid decarbonization.

为了使发电完全脱碳，需要在太阳能和风能利用率低的时候满足电力需求。天然气联合循环（NGCC）发电与碳捕获与封存（CCS）技术可以减少发电厂的二氧化碳排放，这是为此目的提出的一项技术。然而，CCS并不能捕获所有发电厂的二氧化碳排放，也不能解决NGCC发电厂上游的甲烷排放问题。此外，CCS的成本通常没有根据容量因素进行评估，而容量因素代表了NGCC发电厂在低碳电网中的可能用例。因此，我们评估了未捕获的逸散性甲烷排放对CCS气候效益的影响，以及NGCC容量因子对CCS经济效益的影响。考虑到随时间和区域变化的甲烷泄漏，我们发现CCS减少了系统级温室气体排放21% %至88% %，其余的气候影响主要是由于未捕获的甲烷排放。美国平均甲烷泄漏率为2.95 %，CCS可将系统级温室气体排放量减少47-71 %。此外，我们估计CCS相关的资本和运营支出只有在高容量因素和存在财政支持（如加州限额与交易计划和美国45Q税收抵免）的情况下才能使CCS具有成本效益。这些发现突出了将NGCC与CCS结合使用以实现电网完全脱碳的重大技术和经济挑战。

This paper examines how the distribution of political power affects rural electrification and the urban-rural electricity access gap in Sub-Saharan Africa. Using panel data for 45 countries from 2000 to 2022, we apply instrumental variable quantile regression (IVQR) to capture heterogeneous effects across the distribution of electricity outcomes. Results show that more equitable political power—across rural-urban lines, gender, socioeconomic status and social groups—significantly improves rural electrification and reduces electricity inequality. These findings are robust to alternative estimation techniques and highlight the role of political inclusion in promoting energy equity. They underscore the need for institutional reforms to ensure balanced representation in energy policymaking.

Electric vehicle (EV) depot charging is critical for truck fleet operators to convert their conventional vehicles to zero-emission vehicles (ZEVs). This study uses California as the context and considers two example fleets: a fleet of medium-duty delivery trucks and a fleet of heavy-duty short-haul trucks. Assuming trucks are charged at a depot by direct current (DC) fast chargers (50 kW, 150 kW, or 350 kW) or high-power level 2 chargers, we estimate charging infrastructure cost as a function of the EV fleet size. Results indicate that per-vehicle infrastructure cost would decrease substantially as the fleet size increases, though infrastructure cost is very sensitive to charger utilization rates. The higher the charger utilization, the lower the infrastructure cost would be, as the depot would need fewer chargers installed. Therefore, one cost reduction strategy is to improve daily utilization rates to reduce the charger count demand and thus reduce the infrastructure cost.

电动汽车（EV）车场充电对于卡车车队运营商将其传统车辆转换为零排放车辆（zev）至关重要。本研究以加利福尼亚州为背景，并考虑了两个示例车队：中型运输卡车车队和重型短途卡车车队。假设卡车在仓库通过直流（DC）快速充电器（50 kW、150 kW或350 kW）或大功率2级充电器充电，我们估计充电基础设施成本是电动汽车车队规模的函数。结果表明，随着车队规模的增加，每辆车的基础设施成本将大幅下降，尽管基础设施成本对充电器利用率非常敏感。充电器利用率越高，基础设施成本就越低，因为电池厂需要安装的充电器越少。因此，降低成本的策略之一是提高日常利用率，以减少充电器数量需求，从而降低基础设施成本。

Electricity affordability is a salient policy concern in California. We compare drivers of increasing utility costs for three types of power providers in California: investor-owned utilities (IOUs), publicly owned utilities (POUs), and community choice aggregators (CCAs). Since 2019, the IOU and CCA residential baseline electricity rates have increased by 44–80 % after accounting for inflation, making them some of the most expensive power providers in the United States. POU prices, however, remained nearly unchanged. We compare long-term trends in capital assets, returns, and operation and maintenance expenses to identify sources of increasing utility costs, one of the factors contributing to rising electricity prices in the state. Across IOUs, generation capital assets have declined. Fuel and power purchase expenses have increased, although these increases remain within their historical ranges. Transmission and distribution (T&D) expenses have increased significantly and are the majority of overall costs. T&D operations and maintenance spiked following major wildfires after years of remaining constant despite an aging and expanding electricity grid. CCAs reach price parity with IOUs due to the high costs of T&D infrastructure and exit fees levied on them. POUs, which service smaller territories with low wildfire risks, also expanded their T&D capital assets, operations, and maintenance expenses, but the increase is modest. We foresee continued price divergence among power providers due to wildfire mitigation costs, which will have important affordability consequences.

在加州，电力的可负担性是一个突出的政策问题。我们比较了加州三种类型的电力供应商的公用事业成本增加的驱动因素：投资者拥有的公用事业（iou）、公共拥有的公用事业（pou）和社区选择的聚合商（cca）。自2019年以来，考虑到通货膨胀因素，IOU和CCA住宅基准电价上涨了44 - 80% %，使它们成为美国最昂贵的电力供应商之一。然而，POU价格几乎保持不变。我们比较了资本资产、回报、运营和维护费用的长期趋势，以确定公用事业成本增加的来源，这是导致该州电价上涨的因素之一。在所有借据中，发电资本资产都有所下降。燃料和电力购买费用有所增加，但增幅仍在历史范围内。输电和配电（T&；D）费用大幅增加，占总成本的大部分。尽管电网不断老化和扩大，输配电运营和维护费用多年来一直保持不变，但在发生重大火灾后，输配电运营和维护费用飙升。由于输配电基础设施的高成本和对其征收的退出费，cca达到了与借据的价格平价。服务于野火风险较低的较小地区的ppo也增加了他们的研发资本资产、运营和维护费用，但增长幅度不大。我们预计，由于缓解野火的成本，电力供应商之间的价格将继续出现分歧，这将产生重要的负担能力后果。

Uninterrupted access to electricity is critical to the safety and security of American households. More frequent and extreme emergency events increase outages across the country, disproportionately impacting vulnerable communities that experience the most frequent and longest outages, are most sensitive to the loss of electric power, and have the least capacity to adapt to these conditions. This study devises a metric, the Electric Vulnerability Index (EVI), that captures relative exposure, sensitivity, and adaptability to electric outages, and validates this metric against the 2021 Winter Storm Uri in Texas. Though not ubiquitous, similar trends were observed between adjacent areas with higher EVI and those with higher outage rates from this storm. EVI is mapped across the continental United States and offered as a viable approach to quantify a population’s vulnerability to electric outages to aid policymakers, advocates, and energy system stakeholders in the targeted deployment of resilience solutions, such as energy storage, to communities most in need.

不间断的电力供应对美国家庭的安全至关重要。更频繁和极端的紧急事件增加了全国各地的停电，对经历最频繁和最长停电的脆弱社区的影响不成比例，对电力损失最敏感，适应这些条件的能力最低。本研究设计了一个指标，即电力脆弱性指数（EVI），该指标捕捉了对电力中断的相对暴露度、敏感性和适应性，并通过2021年德克萨斯州冬季风暴Uri验证了该指标。虽然不是无处不在，但在EVI较高的邻近地区和风暴造成的停电率较高的地区之间观察到类似的趋势。EVI在整个美国大陆进行测绘，并作为一种可行的方法来量化人口对电力中断的脆弱性，以帮助政策制定者、倡导者和能源系统利益相关者有针对性地向最需要的社区部署弹性解决方案，如储能。

Accelerating room air conditioner efficiency in India: Grid, economic, and policy implications through 2035 加速印度室内空调效率：到2035年的电网、经济和政策影响

India is poised for a rapid surge in space cooling demand, driven by rising incomes, urbanization, and intensifying heat. Between 2025 and 2035, the country is expected to add 130–150 million new room air conditioners (ACs). If Minimum Energy Performance Standards (MEPS) continue to improve at the historical rate of 2–3 % annually, room ACs alone could contribute over 180 GW to peak electricity demand by 2035-nearly 30 % of the projected national total. This study evaluates the impact of an accelerated MEPS trajectory, proposing to raise the 1-star threshold to ISEER 5.0 by 2027, ISEER 6.3 by 2030, and ISEER 7.4 by 2033. Drawing on engineering cost analysis, stock turnover modeling, and retail pricing data, we find that this pathway could reduce peak demand by over 60 GW, save 118 TWh of electricity annually, avoid 49 MtCO₂ of electricity-related emissions per year, avert ₹7.5 trillion (∼US$85 billion) in power system investments, and yield ₹0.7–2.3 trillion (∼US$8–26 billion) in net consumer savings by 2035. Contrary to affordability concerns, empirical trends show that higher efficiency does not increase AC prices. These results highlight the value of ambitious MEPS as a cost-effective strategy for improving grid reliability, reducing emissions, and advancing consumer welfare in emerging economies.

在收入增长、城市化和高温加剧的推动下，印度即将迎来空间降温需求的快速增长。2025年至2035年间，中国预计将新增1.3亿至1.5亿台空调。如果最低能源性能标准（MEPS）继续以每年2-3 %的历史速度提高，到2035年，仅室内空调就可以为峰值电力需求贡献超过180 GW的电力需求，接近全国预计总量的30% %。本研究评估了加速MEPS轨迹的影响，提出到2027年将1星阈值提高到ISEER 5.0，到2030年提高到ISEER 6.3，到2033年提高到ISEER 7.4。根据工程成本分析、库存周转模型和零售定价数据，我们发现这条路径可以减少峰值需求超过60 GW，每年节省118 太瓦时的电力，每年避免4900万二氧化碳的电力相关排放，避免7.5万亿卢比（约850亿美元）的电力系统投资，并在2035年之前产生0.7-2.3万亿卢比（约80 - 260亿美元）的净消费者储蓄。与负担能力问题相反，经验趋势表明，更高的效率并不会增加空调价格。这些结果突出了雄心勃勃的MEPS作为提高电网可靠性、减少排放和提高新兴经济体消费者福利的成本效益战略的价值。

Heat pumps emit more carbon than efficient fossil heating in new england because of dirty marginal power generation fuels 在新英格兰，由于使用肮脏的边际发电燃料，热泵比高效的化石供暖排放更多的碳

Electrification by substituting heat pumps for fossil heating assumes carbon emissions are thereby lowered. However, detailed studies of the marginal emissions impact from a heat pump have rarely been validated against historical data. This study estimates emissions using a backcast of actuals from 2018 in New England to infer the impact of heat pump conversions. The model suggests a heat pump would have emitted 68 % more CO2 than a 90 % efficient gas furnace. But if oil and coal plants had not been activated, the model suggests heat pumps would only have emitted 3.3 % more CO2 than a gas furnace. Carbon emissions vary with the relative efficiency of the marginal electric generator and heat pump. Heat pump efficiency declines during cold weather, coinciding with peak heating load. Emissions are dominated by short periods when coal and oil generation resources operate, coinciding with low temperatures. But even with coal and oil plants on the system, a hybrid heat pump - gas furnace configuration reduces CO2 emissions 5.6 % compared to a gas furnace alone. Thus hybrid operation is preferred where fossil fuels are primarily on the margin.¹

用热泵代替化石燃料供暖的电气化假设碳排放因此降低。然而，对热泵边际排放影响的详细研究很少根据历史数据进行验证。本研究使用新英格兰2018年的实际数据来估算排放量，以推断热泵转换的影响。该模型表明，热泵比效率为90% %的煤气炉排放的二氧化碳多68% %。但是，如果石油和煤电厂没有被激活，该模型表明，热泵只会比煤气炉多排放3.3% %的二氧化碳。碳排放量随边际发电机和热泵的相对效率而变化。在寒冷的天气里，热泵效率下降，与热负荷高峰相吻合。排放主要发生在煤炭和石油发电资源运行的短时间内，同时气温较低。但是，即使在系统上有煤炭和石油工厂，与单独的煤气炉相比，混合热泵-煤气炉配置减少了5.6% %的二氧化碳排放。因此，在化石燃料基本处于边缘的地方，混合操作是首选

Thus hybrid operation is preferred where fossil fuels are primarily on the margin.<span><span><sup>1</sup></span></span></div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"38 3","pages":"Article 107477"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144222446","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}

Australia’s energy policy faces contradictions between decarbonization goals, energy affordability, and fossil fuel exports. Electricity rebates temporarily lower CPI inflation but distort market signals, reduce efficiency incentives, and create opportunity costs. Critics argue rebates mask grid instability and delay investments in dispatchable or renewable energy. Simultaneously, fossil fuel exports (e.g., LNG) sustain living standards but clash with global climate commitments. Scope 3 emissions from exports dwarf domestic reductions, undermining climate leadership claims. This analysis highlights policy incoherence: short-term rebates and export revenues perpetuate fossil dependence, complicating renewable transitions.

澳大利亚的能源政策面临着脱碳目标、能源负担能力和化石燃料出口之间的矛盾。电力补贴暂时降低了CPI通胀，但扭曲了市场信号，降低了效率激励，并产生了机会成本。批评人士认为，补贴掩盖了电网的不稳定，推迟了可调度或可再生能源的投资。同时，化石燃料出口（如液化天然气）维持了生活水平，但与全球气候承诺相冲突。范围3的出口排放使国内减排相形见绌，削弱了气候领导地位的主张。这一分析凸显了政策的不一致性：短期退税和出口收入使对化石燃料的依赖永久化，使可再生能源转型复杂化。
