Some general information about electricity trading arrangements in the UK

Elexon sushi video. Tries to explain the balancing of the UK's electricity grid

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.

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.
