Abstract
Because of the increase in population and electric demand we are obliged to expand the entire network of electricity generation and distribution. Power plants as electrical generating stations are the most important part of the power system. The site of power plant affects the amount of generated energy, power plant’s productivity, cost of power generation and transmission (loss of energy), economical development and environmental impacts. Almost the same could be said for the other parts of the electricity network, including substations transmission lines etc. In this paper the whole issue of power generation and distribution development is covered along with the roles that GIS can play in conducting the whole process more effective and efficient. First it is explained how to discover the areas that population change demands for the expansion of the electricity network. This depends not only on the population growth, but also on the changes in the culture, urbanization and also the industrialization and many other factors.

Based on the availability of the fossil-fuel resources in the country, most of the power generation expansion is directed towards the thermal power plants. In this article, the necessary conditions for the establishment of thermal plants are comprehensively studied. Many of these conditions are related to the physical aspects of the area, including Geology and geological faults, climatology, water resources, fuel supply, roads and high ways, load distribution, available electric network, topography of the area. Therefore, a data requirement analysis has been carried out for the selection of the required spatial data layers. Moreover, the scale, structure, format and other aspects of the required data are studied and decided. Finally different models and methods for the integration of the data and the selection of the sites for the power plants are studied and compared. Similarly the whole process is performed for the selection of both the substation locations and the power transmission lines.
