Using hourly prices in Belgium
Prices shown are the Belgium (BE) day-ahead auction results, converted to the local price of one kilowatt-hour at the European Central Bank's daily reference rate. If you're on a dynamic or spot-indexed tariff, the hourly pattern above is exactly what drives the variable part of your bill, so shift EV charging, laundry and water heating into the green hours to save. On a fixed tariff, the chart still shows where the market is heading and whether a dynamic contract could pay off for you.
Every supplier in Belgium buys at these prices
The day-ahead auction produces one price per hour for the whole bidding zone, so suppliers don't differ on the hourly pattern, only on their margin, standing charges and whether your contract passes hourly prices through at all. Grid fees and taxes are added on top of every figure here; switch on Show my real price above to include them.
