Interesting read, I was wondering what happened that day. As an operator of a small network of fastchargers, we were delighted to have a purchase price of negative 20cent per kw. Which is huge.
If you look at consumers, only a tiny minority has an electricity contract that is directly based on day-ahead prices.
I have to say that we are implementing dynamic pricing and want to have fixed margin of 0.30/kw, I believe we will be the first medium sized operators who will have full price transparency. We are going to be publishing 'tomorrows' prices on our website, even.
