I explore this question in the context of the electric power sector in India, where electricity is transacted primarily via long-term bilateral contracts and state-owned distribution utilities self-schedule contracted power plants to meet their demand. The absence of a centralized and dynamic market-based economic dispatch mechanism generates short-run misallocation in electricity dispatch and distorts long-run investment decisions, such as the incentive to invest in flexible generation capacity and energy storage to complement renewable-based capacity. Using panel data on coal price schedules and monthly plant-level operations from 2012 to 2020, I construct a predicted delivered coal price index to estimate the elasticity of plant utilization with respect to fuel prices. I find that the demand for electricity from coal-fired power plants with a higher share of capacity allocated under long-term bilateral contract(s) is less sensitive to changes in coal prices, implying that the existing market design could erode some of the environmental benefits of carbon pricing.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"38 4","pages":"Article 107495"},"PeriodicalIF":2.2,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145748236","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 examines the performance of alternative short-term electricity market designs for managing the uncertainty associated with wind power generation. The markets vary by their opportunity for wind power plants to respond to changing wind forecasts prior to final supply. In the two-stage market, subjects receive information about their forecasted wind availability in the day-ahead stage, and choose a quantity offer to maximize their profit for the day before the actual wind output is realized. In the multi-stage market, subjects receive an additional signal on their forecasted wind availability in the intraday stage, and may revise their quantity offer to maximize their profit before the actual wind output is realized. We develop a model of rational profit-maximizing behavior in sequential markets, derive theoretical predictions for individual behavior and market outcomes, and design laboratory experiments to test the model’s predictions. Subject decisions in the day-ahead stage of the multi-stage market rely on the prior probability of the wind state and mostly ignore the potential value of the upcoming intraday signal. This is consistent with findings of the experimental economic literature showing that decision makers may fail to make rational decisions when faced with uncertainty. Our results also suggest that the multi-stage market leads to lower uplift payments and higher revenues for the wind power producers.

The Low-Income Home Energy Assistance Program (LIHEAP), the United States’ primary mechanism for delivering energy assistance to low-income households, increasingly faces constrained capacity and an uncertain future. This paper investigates how state-level variations in LIHEAP implementation affects program participation. Drawing on LIHEAP State and Territory Plans, we examine variation across three key dimensions: (1) timing and duration of assistance relative to shifting seasonal energy needs; (2) the type of administering state agency and the degree of coordination across the social safety net; and (3) outreach strategies. Using 2016–2022 linear regression estimates, we find that states where LIHEAP is administered by community service agencies are associated with higher participation rates, while administration by welfare agencies is associated with higher total participation. LIHEAP programs that coordinate application processes with other social programs are associated with reaching a larger share of eligible households, whereas passive outreach methods show limited effectiveness. Cooling degree days are not statistically associated with participation, suggesting a lag between evolving climate conditions and program adaptation. Finally, relying on 2024 data, we observe descriptive evidence of misalignment between state weather trends and funding periods. Together, these findings highlight the importance of program design and implementation in shaping access to energy assistance. We offer state-specific insights to improve LIHEAP’s responsiveness and enhance the program’s capacity to support low-income American households amid a changing climate.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"38 4","pages":"Article 107521"},"PeriodicalIF":2.2,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145624122","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}

Balancing data security and the development of intelligent connected vehicles has become a critical issue for the global automotive industry. Understanding how the public processes risk information and the key factors influencing their behavioral intentions in response to data security concerns in intelligent connected vehicles is essential for promoting the sustainable development of the IoV industry. In this study, we examined a typical data breach incident involving Chinese intelligent connected vehicles that occurred in December 2022 and conducted a survey of 468 vehicle owners. Using a two-stage hybrid Partial Least Squares Structural Equation Model (PLS-SEM) and Artificial Neural Network (ANN) technique, we analyzed how the public processes information and forms behavioral intentions in response to this risk, as well as the relevant influencing factors. The results indicate that product knowledge, risk perception, and systematic information processing significantly affect citizens' coping behavioral intentions. Among them, product knowledge emerges not only as the strongest predictor of behavioral intentions but also as a key antecedent of risk perception, information need, and information seeking. Risk perception also facilitates information need and systematic processing to varying degrees. Furthermore, information need plays a significant mediating role between both product knowledge and information processing, as well as between risk perception and information processing.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"38 4","pages":"Article 107512"},"PeriodicalIF":2.2,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145104776","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}

As India expands its renewable energy capacity and competitive electricity markets, modernizing procurement mechanisms is essential. Market-based PPAs enhance flexibility through dynamic pricing and real-time market alignment, while Contracts for Difference (CfDs) provide revenue stability for generators and allow utilities to benefit from market fluctuations. Revenue-sharing Contracts (RSC) create a risk-reward balance by linking revenues to market conditions and generation performance, thereby incentivizing efficiency and investment in renewables.

The findings are analytically rigorous and empirically validated using real-world data from Texas, revealing that behavioral frictions materially affect tariff performance. In particular, Net M and Net P&S outperform FIT in terms of social welfare under finite attention, while FIT offers greater revenue stability for electrical retail companies. These insights are timely and policy relevant, underscoring the imperative to align solar pricing strategies with actual user behavior.
