Calibrating the model to Italian data, our analysis predicts that an EU-wide cap on natural gas prices significantly reduces electricity prices, while consumed quantities increase only marginally. A mandated reduction in electricity demand during peak hours leads to modest price declines, while a national cap on gas prices for electricity generation triggers a sharper increase in consumption due to cross-border trade incentives. These findings suggest that emergency interventions can mitigate the short-term impact of price shocks, though they may also introduce inefficiencies in terms of energy consumption and market distortions.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"38 4","pages":"Article 107474"},"PeriodicalIF":0.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144314298","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}

Therefore, in terms of total surplus, the French electricity sector should have been barely hit, if at all, by the surge in fossil fuel prices during the 2022 energy crisis. In practice, however, the French government spent billions of euros in subsidies to electricity consumers, the incumbent utility – who operates the whole nuclear fleet – recorded its worst yearly financial result to date, and total electricity imports exceeded exports for the first time in more than 40 years. Although these outcomes can largely be attributed to bad luck, the extent to which they could have been mitigated through better market design and public policies is an open question. This article argues that existing policies, through their implied incentives to share and manage long-term risks, played a critical role in how France fared during the energy crisis. Consistently, reforming long-term risk-sharing mechanisms has emerged as the most pressing issue to address. Looking forward, however, updating short-term wholesale market design will likely prove increasingly important to better support a low-cost and reliable energy transition.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"38 3","pages":"Article 107483"},"PeriodicalIF":0.0,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144281050","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}

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.<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":"2025-06-06","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}

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.

The research evaluates five dimensions of agricultural recovery: profitability, productivity, job creation effects, investment attraction, and household expenditures. The analysis, conducted using propensity score matching, indicates that solar-powered irrigation significantly enhances agricultural profitability, with solar users earning an average of $20.42 more per acre compared to diesel users (p = 0.001). Wheat productivity showed a modest increase from 0.151 to 0.179 tons per acre, though the difference was statistically insignificant (p = 0.365). Similarly, solar-based farms generated an average of 87.42 working days per year, compared to 75.30 days for diesel-based farms, but this difference was also not statistically significant (p = 0.60). Despite these mixed outcomes, the study highlights a significant shift towards the cultivation of summer crops, such as cotton, facilitated by more reliable water supply provided by solar-powered irrigation. These findings emphasize the importance of targeted interventions, including the promotion of advanced irrigation techniques and financial support for infrastructure development. Such measures are critical for maximizing the benefits of solar-based irrigation and ensuring broader, more sustainable agricultural recovery in the region.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"38 2","pages":"Article 107471"},"PeriodicalIF":0.0,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143855971","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}

It serves as an initial contribution to creating incentives for greater resilience in the energy system. The central problem to be solved is the information asymmetry between network operators and network users in terms of outage and backup costs. We present an auction of priority positions among network users by applying the Vickrey-Clarke-Groves mechanism, using a numerical example, to solve this problem. Priority positions imply an externality: the priority of one user means that others are reconnected later and incur higher costs. Under this mechanism, each winning bidder pays for the externality exerted on the other bidders by holding a certain position, excluding one’s own bid, which induces truthful bidding. By minimizing the damage from power supply interruptions, the mechanism improves the resilience of the power system not only in the short term but also in the long term.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"38 2","pages":"Article 107470"},"PeriodicalIF":0.0,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143817167","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}
