Iran faces several pressing issues, including escalating energy consumption, inadequate price signaling to address consumption patterns, increasing greenhouse gas emissions, and prevailing distributional challenges related to energy subsidies. Consequently, reforming energy carrier subsidies in Iran becomes an imperative task. However, numerous obstacles hinder the effective implementation of this policy, presenting substantial challenges. This study employs a comparative approach that incorporates expert opinions and utilizes the Fuzzy Analytical Hierarchy Process (FAHP) method with a holistic perspective to evaluate and rank the barriers to energy subsidy reform. The identified barriers are categorized into three groups based on specific criteria: 1) political and social barriers, 2) economic barriers, and 3) institutional and governance barriers. Subsequently, thirteen sub-criteria have been established, considering Iran's economic conditions. The research findings highlight the significance of economic barriers, accounting for 53% weight, followed by political and social barriers with 26%, and institutional and governance barriers with 21%. Notably, among the economic barriers, the high dependency of energy industries on the country's exports and the government's concerns about potential damage to foreign exchange revenues, particularly under sanctions, emerge as crucial factors. Regarding political and social barriers, the prevalent mindset of entitlement among citizens regarding energy subsidies proves noteworthy. Additionally, the lack of a cohesive and reliable database for implementing energy subsidy reform policies assumes utmost importance among institutional and governance barriers. Based on these results, it is imperative for the government to undertake measures encompassing formulation, implementation, and evaluation in all dimensions of energy subsidy reform.

The main goal of this research is to design a composite economic-energy-environmental performance index (3EPI) for Iran's economy by generalizing the methodology of Khramov and Lee (2013) as well as evaluating the effect of variables on the composite performance index during the period from 1991 to 2021 using a time-varying parameters model (TVP). The 3EPI index is calculated in a weighted and unweighted form, and the trend is separated from the cyclic with the Hodrick-Prescott filter. The findings show that the long-term trend of the 3EPI index is in the range between 35 and 60 percent, which is significantly different from the base number of the index (i.e. 100 percent). The chronicle of the index shows that the worst performance is related to the implementation period of the structural adjustment policy (1994 and 1995), the first round of economic sanctions (2012), and the intensification of economic sanctions in the latest round of sanctions (2019). The best performance is related to the two periods of the relative stability of macroeconomic variables and the period of implementation of the JCPOA agreement. The results of the application of the TVP model show that, from 2011 to 2021, the variable of the budget deficit to GDP ratio had the most significant negative impact on Iran’s 3EPI performance index

Due to the increasing use of storage as one of the effective methods for peak demand management and increasing the reliability of the electricity network, prioritizing the use of storage is necessary. The purpose of this study was to conduct a multi-criteria decision making (MCDM) approach to prioritize selected sub-distributive substations of Tehran for peak shaving, curve leveling, and economic criteria using battery storage. Also, the Shannon entropy weighting method and SAW implementation method were implemented. After prioritizing the posts and identifying the priority posts, we determine the appropriate size of the storage and determine the delay time, and the amount of benefit from delaying the development of the post when using the electrical energy storage. In this study, we used real data obtained from Tehran Regional Electricity and the data used for the 63 to 20 kW substations “EKBATAN”, “AZADI”, “AZARBAIJAN”, “ABOUZAR”, “SINA”, “DEPO”, and “YAKHCHI-ABAD”. The results show that the maximum installed storage capacity calculated for the priority post (i.e. DEPO) is 119.66 MWh and the maximum storage capacity is 18 MW. The most suitable storage size for installing is 120 MWh. Using the storage at the selected post will delay the development of the post for 7 years and the economic benefit is 40% of the investment cost.

As the first link between the host governments and oil companies, oil contracts arrangements have an important role to risk sharing between contract parties. In this regard, the main objective of this study is to provide a comparative evaluation of the risk factor (Cost Risk, Price Risk, Production Risk) of National Iranian Oil Company (NIOC) in Buy-Back (BB), Production Sharing Contract (PSC), and Iranian Petroleum Contract (IPC), and choosing the best contract based on the risk factor. Based on the results of the Wilcoxon Ranking Test, the average of the NPV of the NIOC in the IPC is more than the other types of contracts. However, the NPV in the IPC does not significantly differ from BB. Other findings revealed that the most risk of rising costs to the NIOC is related to the BB, IPC, and PSC, respectively. In addition, the most risk associated with a reduction in oil production is related to BB, IPC, and PSC, respectively. the most risk associated with the oil price reduction for the NIOC related to the IPC same as BB contracts that greater than PSC.

The main objective of this study was to evaluate the effects of oil revenue, productivity and money growth rate shocks in macro-economic variables, in the context of a DSGE model with features such as the needs of infrastructure development and the existence of public investment inefficiencies and its comparison with Permanent Income Hypothesis (PIH model). The results show that oil revenue shock has increased consumption, government current and capital spending and has reduced inflation in the short run, although has increased in the medium term due to the demand side push. The results revealed that the National Development Fund and consequently the Fund's concessional facilities to the private sector has been raised. In addition, because of the structure of the economy that was largely unproductive and the government activity in the economy would lead to crowding out effect, the oil revenue growth has little effect on the growth of non-oil producing sector. More over, each of the productivity and monetary shocks in the model has resulted the same theoretical expectations. Results also show that the implementation of fiscal policy based on PIH Scenario has better effects on macroeconomic variables in comparison with the business as usual scenario.
