As conventional electrical networks evolve to be smarter, large-scale investments are required for new technological systems. This transformation creates the need to develop smart grid roadmaps for each national, regional or municipal-level network. After the liberalization of the electrical distribution sector in Turkey, smart grid implementation activities and R&D efforts have accelerated. In this context, the Turkey Smart Grid Roadmap (TR-SGR) Project was initiated as one of the maj or milestones in providing a detailed guideline for the future of smart grids in Turkey. In this paper, an overview of the proj ect and the Clustering Based Smart Grid Maturity Model (C-SGMM) are introduced. An evaluation of the maturity level of the distribution network in Turkey is provided. In addition, the Turkey 2035 smart grid vision and its main objectives are presented and key points in the 2025 project-based action plan are described.
