With a dynamic contract, the price follows the wholesale market. For electricity the price changes every hour, for gas every day. The customer pays that market price, plus a fixed fee per kWh and a fixed amount per month.
Fixed, variable or dynamic
- Fixed: one price for the whole term. The supplier carries the price risk and charges a margin for it.
- Variable: the price follows an index and is adjusted periodically.
- Dynamic: the price follows the market per hour (electricity) or per day (gas).
What do you need?
For electricity you need a digital meter that records consumption per quarter hour. Only then can consumption be settled at the correct hourly price.
Who benefits?
Mainly those who can shift consumption: an electric car, a heat pump, a boiler or a home battery. Those who consume during cheap hours pay noticeably less. Those who cannot or do not want to simply follow the market average, without a built-in risk margin.
How is the price determined?
On the day-ahead market, prices for the next day are set. Those prices are public. The contract settles your consumption at those prices, plus the agreed fees.
Can the price go negative?
Yes. At times with a lot of sun or wind and little demand, the market price can drop below zero. With a dynamic contract, that advantage goes to the customer.
What about price peaks?
They exist too. A dynamic contract rewards flexibility, and therefore asks for some awareness of when you consume. Good information about tomorrow’s prices is therefore part of the offer.
