What is a dynamic energy contract?

With a dynamic contract, you pay a different price for electricity every hour, based on the wholesale price (ENTSO-E). During the day with lots of sun, electricity is often cheaper, in the evening more expensive.

How much can I save with a dynamic contract?

With solar panels, you can save €100-400 per year by shifting consumption to cheap hours. With a home battery, this can increase to €200-500 per year.

What are the risks of a dynamic contract?

Prices can fluctuate significantly, especially in winter. Without flexible consumption or a battery, you could end up paying more. You need to actively manage or automate your consumption.

Dynamic vs Fixed Contract

Dynamic or fixed energy contract: which suits you?

With solar panels, you have extra choices. When does a dynamic contract pay off? And when is it better to choose security with a fixed rate?

Comparison at a glance

	Dynamic	Fixed
Price structure	Changes hourly (ENTSO-E)	Fixed price per kWh
Risk	Price spikes possible	Predictable costs
Savings potential	€100-400/year extra	No extra savings
Effort required	Adjust consumption	Nothing needed
Best for	Flexible use, EV, battery	Security, rarely home

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.
