How is the energy price built up with a dynamic contract?

At Blue Current Energy, you see two types of prices:

Stock market price: This is the current market price at which we purchase energy on the European energy market. This price does not include VAT and other costs and is determined by supply and demand.
All-in price: The purchase fee - an amount per kWh or m3 that we pay for purchasing energy and for the imbalance risk and the energy tax - is added to this, the tax you pay based on your stated annual consumption and 21% VAT on the stock market price.
