Some videos for your reference: Who is Elexon? For the UK market, they are the system administrator. https://www.youtube.com/watch?v=A5j-S6VGqpw#action=share Some general information about electricity trading arrangements in the UK https://youtu.be/UDv04q3U6e0 Elexon sushi video. Tries to explain the balancing of the UKs electricity grid https://vimeo.com/65768597 The videos above are UK centric, but our current interest is Europe wide. Feel free to research the other markets. This is a longer video that to me explains why there is such large opportunity going forward for the electricity traders who are able to efficiently analyse supply and demand fundamentals and move power between countries, for the benefit of all. https://youtu.be/gacGuWjqKco. As mentioned in the add, once Europe is conquered, we do genuinely intend on going global. The American power markets look next on the plate, followed by the Australian and Japanese.
