Mankind has been interwined with energy sources throughout the ages. Since the beginning of industrial revolution, fossil resorces have been used intensively due to increasing energy requirements. Today, when we look at the world and our country in general, a trend towards renewable energy sources is growing day by day. Especially in the last 10 years, the share of energy produced from renewable and clean energy sources has been extraordinarily increased. Concentration of renewable energy sources at some regions, especially scattered as lowpower plants in the several geographic locations causes many problems in the electricity grid in terms of energy quality. If the electricity grid cannot be strengthened in parallel with the increase of production power plants, the quality of production and continuity of electricty may not be achieved, even though production resources increase. It is certain that, in the future, the effects of renewable energy sources on the grid, and the positive and negative aspects of each system according to the source will be further investigated. It is because each renewable energy source included in the distribution and transmission system should be examined together with the objectives of satisfying the demand of the system and increasing the quality. It is important to determine in advance which parts of the network are available for connection of the renewable power plants, in order to ensure the stable operation of the electricity network. Therefore, the current state of electricity networks in Çanakkale region has been investigated in this study and it has been determined what should be done in transition to renewable energy systems
