About the courses: My courses are based on energy projects I've worked on as a consultant for private companies, governments, and European institutions. For each course, I rebuild the model from scratch using public or synthetic data, so the commercial logic and implementation patterns match what's used in practice, without any client confidentiality concerns. The attached PDF describes each of the 120 courses in the library. About me: I am Dr. Spyros Giannelos, PhD in Energy from Imperial College London. I have published extensively across energy systems, power-grid planning, and optimisation (1300+ citations, h-index 25). I have also led private, government, and European energy consultancy projects across the UK and European Union. [Upgrade here]
