How does a dynamic contract work?
With a dynamic contract, you pay a different price every hour, based on the wholesale price on the European energy market (ENTSO-E). The price is announced a day in advance.
Typical prices on a sunny day
03:00 at night
€0,08/kWh
12:00 noon
€0,05/kWh
18:00 evening
€0,35/kWh
With solar panels, you benefit twice: during the day electricity is often cheap (lots of sun = lots of supply) and you use your own free electricity.
When to choose dynamic?
You have flexible consumption
You can shift appliances to cheap hours (washing machine, dishwasher, boiler).
You have an electric car
EVs can charge at night or during the day when electricity is cheap. Potential €200-400/year savings.
You have (or plan) a home battery
With a battery, you can smart charge at low prices and discharge at high prices.
You're willing to follow prices
You regularly check prices or use automation (smart plugs, apps).
When to choose fixed?
You want certainty
You know exactly what you pay, no surprises with price spikes.
You're rarely home during the day
You can't shift consumption to cheap hours.
You don't want hassle
You don't want to think about when to run the washing machine.
Note: dynamic is not always cheaper
During periods of high prices (winter, little sun/wind), dynamic rates can spike significantly. Without flexibility or a battery, you could end up paying more than with a fixed contract.
