As a Belgian Ecopower customer on a dynamic pricing contract, the raw EPEX spot price is only part of what I actually pay per kWh. There are taxes, levies, network tariffs and Ecopower's own margins on top, and I wanted to see the real number in my dashboard instead of doing the sums in my head.

Ecopower Dynamic Prices sits on top of your existing EPEX Spot or Energi Data Service integration and works out the actual hourly price. It applies Ecopower's consumption and injection multipliers, the Belgian energy levies (GSC and CHP green certificates), distribution network tariffs, the energy contribution and special excise tax, and finally VAT.

Every cost parameter is a number entity in Home Assistant, so you can tweak the values yourself when the rates change.
