This study aims to present the existing legislative framework for the arbitration of disputes which arise from the energy sector focusing on institutional permanent arbitration of RAE. In the context of this thesis, comparisons are made regarding to energy arbitration at the international level. Specifically, laws and particularly those applicable in international as well as domestic arbitration regarding energy disputes are presented in detail. Moreover, the provisions governing the permanent arbitration of RAE are thoroughly analyzed. Furthermore, the manner in which RAE arbitration has been organized is captured, focusing on the legal and operational problems that arise. Finally, from a procedural point of view, the first arbitral decision under the auspices of RAE, concerning a dispute about energy, published by an arbitral tribunal is analyzed. Finally, an attempt is made in order to be formulated a reflection for further thinking regarding the development of Greek arbitration legislation under the auspices of the RAE by raising concerns about the apparent influence of Greek arbitration provisions by international arbitration.
