Designing any new project requires an estimation for the minimum amount of money required for initiating it as well as the cost of operations when it is in running process. For any electric power project, the cost of electricity is very significant because it totally affects the end user or the consumer. By using HOMER simulator, these parameters were analyzed. The project was implemented in Hyderabad City, located in southern Pakistan. This city is gifted many natural resources that can produce a considerable amount of power energy for the region. This paper, highlights the average amount of all these resources that can be achieved throughout the year. Keyword: Renewable Energy, Load Cast Management, Optimization Load Forecasting, Solar energy, and Wind energy. 1- INTRODUCTION The increasing demand for energy, the continuous reduction of natural resources of fossil fuels and the growing concern regarding the environment pollution .(1) Determined the mankind to explore new production technologies of electrical power using non-polluting renewable sources, such as wind energy, solar energy, sea waves energy, biomass etc. (2) The renewable energy sources bear a huge potential of conversion electricity, presumably ensuring in the future a large share of all the electric power need of the planet. Among the electric power technologies using renewable sources, those based on the conversion of solar and wind energy are clean, silent and reliable, with reduced maintenance costs, and small ecological impact. (3) The sunlight and the kinetic energy of the winds are for free, practically inexhaustible, involving no polluting residues or greenhouse gas emission. Along with these advantages, the electric Diyala Journal of Engineering Sciences
