Statistics indicate that manufacturing hybrid cars, Gas burner is remarkably growing and the quantity and quality of CNG refuelling stations should be also increased in parallel. In present study and by examining different scenarios, guidelines are provided to resolve the problem of lacking CNG refuelling stations in Tehran and the economic feasibility is examined. Economic assessment is done by COMFAR EXPERT III. For scenarios 1 to 4, internal rate of return (IRR) is 5.89, 15.76, 4.78 and 12.52 respectively. However, these figures are not justifiable economically due to 20% of domestic banking interest rate. Also the net present value of the scenarios is positive and Payback periods are 12, 7, 12, 8 years respectively .The return rate for private sector would be 23% if an individual’s annual income increases 12, 5, 16 and 8 respectively for all four scenarios. Comparing these indicators suggest that although scenario two, that is, constructing small stations by suggested price of 3700 Rials proposed by relevant experts is better than other scenarios, it is not yet economic justification . Therefore, it is better to increase prices for better justification.
