The hydro power is a renewable energy that had a greater influence on people's life during the 20th Century than at any other time. Hydropower played a major role in making the wonders of electricity a part of everyday life and helped industrial development. Tidal power is one way to harness the energy in water. This paper presents a design of Tidal power plant to generate the electro-hydro energy from Red sea in Egypt as a large amount of energy is stored in tides. It is noticed that the Tidal technology is a new and improved system for harnessing the sea tides and that the economic and environmental problems. Also the remote locations offer an opportunity to build small tidal generators (1 to 10 MW). This work presents a new idea to generate limited electrical energy depending on the nature of tide of red sea. A Design of tidal system is presented to feed a limited Dc load near to the beach. Dc load is chosen as Dc lighting beside the beach. Also, an optimization control problem is solved to operate the generating tidal system at the optimal values of the affected system parameters. The paper is very interested as it studies a renewable energy source which must be taken in our consideration as it is an economic and friendly environment.
