The growing natural gas consumption has made it difficult to supply gas to power plants and large industries in the cold seasons and forces these industries to use polluting fuels. One of the consequences of this situation is air pollution. Due to the inelastic demand of natural gas, command policies cannot prevent the increasing trend of gas consumption. So it is necessary to use incentive policies to manage consumption. Recently, in developed countries, regulatory instruments based on exchange of certificates, such as tradable savings certificates based on the market, have been significantly developed and had positive results. Considering the importance of gas consumption management and with the aim of creating a mechanism for certificates of natural gas exchange, in this research, based on the experiences of the leading countries in this field and the results of consensus of the elites, design a mechanism for the exchange of consumption savings certificates of natural gas. The results of Delphi analysis showed that the mechanism of issuing and exchanging natural gas saving certificates is feasible and this mechanism makes households and business units find motivation to save natural gas consumption. Also, power plants and other large industries can fulfill part of their natural gas needs in the cold season by buying certificates from households in the established market, and in this way they can access clean fuel in the cold seasons of the year.

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.

The main purpose of this study is to identify and prioritize different gasoline pricing policies in Iran based on sustainable development indicators using the Delphi method and Analytical Hierarchy Process (AHP). To this end, first, various types of gasoline pricing options along with evaluation indicators of these options were extracted separately in economic, social, and environmental terms by the Delphi method based on reviewing studies and interviews with specialists and experts. In this section, four pricing options for gasoline pricing were extracted entitled (i) “Double pricing of gasoline or continuation of the current trend; (ii) “Single rate gasoline price and cash payment of subsidies to cars; (iii) “Proportional pricing for gasoline consumption; (iv) “Single price of gasoline and allocation of quotas to people instead of cars. Then, these options were evaluated and prioritized in terms of economic, social, and environmental indicators in the framework of the AHP method. The results show that pricing commensurate with gasoline consumption or consumption tax (third option) is the best pricing option among the mentioned options. In this option, environmental and economic indicators are of great importance, and the price of gasoline between the quota price and FOB is determined in proportion to the consumption of individuals and sudden price changes do not occur for all consumers and the price of gasoline is completely dependent on the consumption behavior of individuals. Thus high consumption is always faced with higher taxes and allows for a fairer distribution of subsidies and reduced smuggling incentives for this fuel.
