The major trends and transformations in energy systems have brought many challenges, and cybersecurity and operational security are among the most important issues to consider. First, due to the criticality of the energy sector. Second, due to the lack of smart girds' cybersecurity professionals. Previous research has highlighted skill gaps and shortage in cybersecurity training and education in this sector. Accordingly, we proceeded by crafting a roadmap strategy to foster cybersecurity education in smart grids. This paper outlines the methodology of teaching cybersecurity in smart grids to a large group of students in selected European universities via implementing a Massive Open Online Course. Unlike other solutions, this one focuses on hands-on practical skills without trading-off theoretical knowledge. Thus, flipped learning methodology and gamification practices were used to maximize retention rate. Also, a remote lab that includes a realtime simulator was established for training. Here, the process, outcome, and obstacles to overcome in future deployments, are presented.
