Abstract

The goal of this study is to evaluate a gas and solar power plants (photovoltaic) grid-connected in Ahvaz city, Iran. The results showed that the solar power plant has more economic advantages than gas power plants. A review of the scenarios concerning the replacement of the guaranteed purchase price of the solar power plant showed that even a 50% reduction in the guaranteed power purchase price did not make the project non-economic. In this case, a big value of NPV (about 68 billion rials) has been lost but the return on investment (22.8%) would be reasonable. Of course, it should be noted that this is the most pessimistic case when using the project. Comparison on capital returns for a solar power plant, which is 30% of its guaranteed purchase price (4.2 years) was reduced, and the same factor for the gas plant (2.5 years in Table 5) gives us the choice of the solar power plant. The results of sensitivity analysis showed that the electricty price is more sesitive that other two economic factors. Using of solar power plants because of the microstats crisis in recent years in this region, can help to implement this method and increase the benefits of this environmental technique.
