Abstract
The international trend of interconnecting electric power systems has two dimensions; economical and technical. Electric power systems in the Arab World are not only eligible, but in need for having a unified power grid. The potentials, status and conditions of the existing and future interconnections in this region are overviewed. The development of the six countries interconnection project, including the completed phase of Jordan-Egypt submarine link, is discussed in details. Finally, the main technical problems, which either faced the first stages of the project or expected to face the interconnected systems in the subsequent stages, are highlighted.
