Distributed generation is possible, by means of, various types of electricity generation technology including solar energy (photovoltaic), wind and geo-thermal. But, at present this type of generation mostly focuses on using gas engines (GE) or gas turbines (GT) in Iran. Therefore, electricity generation on these systems is performed by synchronous generators and the thermal regeneration out of gas engines is possible, by means of, CHP or CCHP technology or alternatively, by means of, “combined cycle” in gas turbines, all these make output and economic saving be increased by this type of distributed generation. This especially matters in the places where hot water or steam or heating system is needed and consequently it favorable increases the economic feasibility in a project. On the other hand, whenever network outage occurs, big electricity subscribers can have the advantage of power supply stand –by and support through power distributed generators, installed. Installation of distributed generators (micro-generators) can also make heavy load feeders reduce and the losses decrease, and in turn the reliability increase. In order to utilize the above mentioned advantages it is necessary to select a proper place for installation of the generators, determination of the capacity suitable for them, and using the equipment suitable for safe and secure connection of these generators.

In order to utilize the above mentioned advantages it is necessary to select a proper place for installation of the generators, determination of the capacity suitable for them, and using the equipment suitable for safe and secure connection of these generators.
Besides, the distributed generation has potent advantages among which it can be referred to as follows:
 Power generation with high quality and possibility to simultaneously use generated heat (CHP)
 Ensuring energy supply increase, and avoiding from unforeseen outages of the network
 Very simple and quick installation and operational commissioning
 Reduction of losses in transmission and distribution network
 Building transmission and distribution network not needed
 Reduction in capacity increase needed for the network
 Reduction in electric network dependent
 Reduction of environmental pollutants
 Reduction in energy and demand cost
 More saving in energy consumption
 Management in energy control
 Power performance increase

The technologies acceptable to this subject are as follows:
 Small gas /Thermal turbines, GT
 Micro wind power turbine
 Solar cells, Photovoltaic
 Micro hydro generators
 Gas engines, GE
 Fuel cell.
In today’s modern industrial societies the growth of energy consumption has not only brought the fossil resources on the edge of risk of extinction, but made the world face with irreversible and threatening environmental changes. Therefore, a special part has been given to the renewable energy resources-according to the international plans and policies aimed at the world sustainable development. European Union, for example its 12% generation of the required electric energy allocated the renewable energies in 2010. Also, in Iran studies on renewable energies started by Renewable Energies Organization to deal with this subject for special plans, under the protection of the government. Therefore, Tarah Energy Sepanta Company, with its careful outlook for energy crisis and environmental issues, and in order to be coordinated with the policies and events in the domestic an international renewable energy sections, has begun its activity by establishing the required grounds to realize its goals through ensuring its clients’ consent in this section of industry.
