Evolution of electricity prices
on the wholesale market

The purchase and supply of electricity takes place both in the long term (forward market) and in the short term (spot market). Your electricity price depends among other variables on the contract type and delivery period. Below you will find an overview of the different prices and corresponding price movements.

Forward market

Long-term market where electricity is traded for a future supply.

Spot market

Short-term market where electricity is traded for a supply the next day - Epex Spot.

CAL
The price on the forward market for delivery of the next three years:
CAL+1, CAL+2 and CAL+3.

Q
The price on the forward market for delivery of the next four quarters:

Spot market

The spot market is the short-term market. You buy power which will already be delivered the next day. In contrast to the forward market, the time between purchase and delivery is very short. The short-term prices in Belgium are published by Epex Spot.

eSpot monthly
The electricity price stipulated in your contract is indexed monthly. eSpot monthly is an index based on the arithmetic average of the “settlement” prices of the Day-Ahead (Epex Spot) market, for all days of the month in question.
View
eSpot hourly
The electricity price in your contract is indexed hour-by-hour. The price is published the day before supply on the Day-Ahead (Epex Spot) market.
