By early 2000, there has been introduced in Greece a gradual restructuring process of the electricity sector, towards its liberalization, according to the EU regulations. Several reforms have been undergone that changed the previous status of the sector, where the state-owned monopoly of the fully vertical-integrated Public Power Corporation had prevailed. Discuss the contemporary liberalized electricity market structure in Greece, and a brief review of the major steps and milestones in the last two decades, that reformed the electricity sector. Focus on issues like the unbundling of activities, either regulated or competitive, assets ownership, third party access, actors and roles evolved, main procedures and market organization, as well as the formation of prices and rates. Do not analyze laws, decisions, or other legislative framework, rather discuss the effective structural changes in the sector.
