I think there must be some kind of maximum gap between the cheapest and the most expensive price in order for the market to work. Especially in something as essential as energy. The decision to combine all kinds of electricity under a single market is arbitrary. it was of course made for convenience for the consumer, i suppose. I'm clearly not an expert, so i can't pinpoint exactly what makes the current situation weird. Maybe it's the fact that energy production is a strategical matter often determined at a country level, and so having all the benefit of the "best" strategy lost to the customer, simply because other countries didn't make the correct choice, seem a bit wrong. Or maybe it's the fact that we chose to not make a distinction between local price and foreign price ? ie: have a local price for when the electricity produced is consumed in the same country ?
