Earn Money with a Dynamic Contract

What is a dynamic energy contract?

A home battery is more than just a storage unit for solar power. In combination with a dynamic energy contract, your battery becomes a smart earnings model: charge cheap when electricity costs little, and use your own stored electricity when the price is high.

With a dynamic energy contract (also called an "hourly rate" contract) you pay a different price for electricity every hour. The price follows the wholesale market price (EPEX spot price) and is announced one day in advance.

How it works: charging and discharging

This means electricity is sometimes very cheap (e.g. at night or on sunny afternoons) and sometimes expensive (e.g. early morning and in the evening during cooking).

The principle is simple and works as follows:

Daily earnings model (example)

At night the electricity price is lowest (sometimes even negative!). Your battery charges automatically when the price drops below a threshold.

Batteries with smart control

During the breakfast peak hour, electricity is expensive. You now use your stored cheap electricity instead of expensive grid power.

Concrete example calculation

Your solar panels generate electricity. What you don't use directly goes to the battery. With a dynamic contract, afternoon prices are sometimes also low due to high solar supply.

The evening peak is the most expensive time. Your battery now delivers your stored electricity. You save the maximum difference between cheap charging and expensive consumption.

Which batteries support this?

Let's calculate how much you can save with a 5 kWh battery and a dynamic contract.

Calculate your personal savings

Result: With a 5 kWh battery and dynamic contract you save up to ~€780 per year. Combined with VAT reclaim (21%), the investment is paid back in 3-4 years.

02:00 - 06:00: Charge cheap

• ANWB Energie — Dynamic tariff with good terms
• Zonneplan — Dynamic with own smart plug
• Frank Energie — Transparent prices, no markup

07:00 - 09:00: Use your own electricity

• EasyEnergy — Pay the bare market price
• Choose a home battery — Browse our comparison page or use the calculator
• Switch to a dynamic contract — ANWB Energie, Frank Energie or Zonneplan are good options

Is a dynamic contract risky?

Note: This is an optimistic example. Actual savings depend on daily price fluctuations, which vary by season and day. Budget conservatively for €400-€600 per year.

Step-by-step: how to get started

Not every battery can automatically charge and discharge based on electricity prices. Here are the options:

Can I also feed back to the grid?

Discover how much you can save with a home battery and dynamic contract.

How much do I save without solar panels?

No, not with a home battery. You always charge when electricity is cheap and use your own stored electricity when it's expensive. Without a battery you risk having to buy expensive electricity during peak hours — but with a battery you protect yourself against this.

Need help choosing?

Yes, some systems support this. You can charge your battery when electricity is cheap and feed it back to the grid when the price is high. This is called "energy arbitrage" and can yield extra returns. Do check whether your energy supplier allows this.

• Install the battery — Plug-and-play yourself, or have an installer come
• Set up smart control — Via your battery's app or via Home Assistant
• Enjoy your savings — The battery does the rest automatically

Batteries with smart control for dynamic contracts

Even without solar panels you save with a dynamic contract and home battery. The price arbitrage (charge cheap, discharge expensive) yields an average of €300-€500 per year, depending on your battery capacity and price fluctuations.
