Turkey's energy demand has been increasing rapidly as a result of rapid urbanization and industrialization. The energy investment requirement will be US$130 billion by the year 2020. Electricity energy has a vital importance among the energy sector. In this study the current state of the electricity energy production and consumption of Turkey is investigated and the electricity energy consumption is forecasted by using genetic algorithm. The obtained results are compared with conventional regression analyses techniques, and the estimated values of the Ministry of Energy and Natural Resources. The electricity demand in the year 2020 is estimated to be 315.02 billion kWh compared to the 189.52 billion kWh needed in the year 2007.Energy has become an important topic in the last couple of years and is directly related to the development of a country and the living standards of its people. Turkey is currently in a rapid industrialization process with a young and dynamic population of over 70 million (Tunç et al., 2006). Turkey has been quickly growing in terms of both its economy and its population and the Turkish economy has undergone a transformation from the agricultural to the industrial sector. In parallel, its demand for energy, particularly for electricity, has been rising rapidly. Electricity is an essential source of energy for the technical, social, and economic development of Turkey as in other countries (Hamzaçebi, 2007). Electricity demand forecasting is extremely important for not only aiming at costefficient investments in capacity expansion planning, but also plays an effective role for energy suppliers, financial institutions, and other participants in electric energy generation, transmission, distribution, and markets (Akay and Atak, 2007).Since 1984, the Ministry of Energy and Natural Resources (MENR) has carried out projections for Turkey's energy demands by using the Model for Analysis of Energy Demand (MAED) simulation technique. In the model, energy demand forecasting is realized by considering past situations of the country's economic, demographic, and social structure. Yet, the MEAD model is observed to be unsuccessful compared to the techniques based on observatory techniques (i.e., meta heuristic techniques; Ediger and Tatlidil, 2002).
