Open Energy Manager

The Open Energy Manager automatically controls your solar panels and battery to keep your energy costs as low as possible. Later this year, heat pumps and electric charging stations can also be controlled.

The financial benefit is greatest with a dynamic energy contract, but the Energy Manager can also provide benefits with a variable or fixed contract.

The Energy Manager reduces your electricity costs in several ways:

1 . Use more of your own solar energy (increase self-consumption)

The more of your own generated solar energy you use directly yourself, the less electricity you need to purchase from your energy supplier.

This benefit will become even greater when the net metering scheme is completely abolished in 2027.

• The battery plays an important role in this:

• During the day (for example in the afternoon), a surplus of solar energy is stored.

• In the evening, you use this stored energy, so that you need to purchase less or no electricity.

• In the future, the Energy Manager may also allow your heat pump or electric vehicle to heat up or charge extra when a lot of solar energy is available.

   

2. Smart purchasing at low prices

On days with little sunshine (for example in winter), you may generate insufficient energy for your own consumption.

In that case, the battery can purchase electricity at times when the electricity price is low (sometimes even negative with a dynamic contract). You use this energy later, when the price is higher.

3. Smart feed-in at high prices

On sunny days (for example in summer), you may produce more solar energy than you consume yourself.

In that case, the battery can feed energy back into the grid at times when the price is highest.

4. Trading with remaining battery capacity

If there is still capacity available in the battery, it can also actively respond to price differences:

• Purchase electricity when it is cheap (for example when there is a lot of sunshine in the Netherlands).

• Sell electricity when it is more expensive (for example in the evening when demand is high).

How does the Energy Manager determine this?

The Energy Manager makes a daily forecast of:

• The expected solar energy production

• Your expected energy consumption

• The electricity prices for the next day (day-ahead prices)

Based on this, the system automatically calculates an optimal strategy. This results in control signals for the battery and solar panels.

If something changes during the day (for example the weather or your consumption), the Energy Manager automatically adjusts the planning.

Explanation of the graphs in the app

In the current version of the app you see:

• Light blue bars above the zero line: electricity that you have imported from the grid.

• Dark blue bars below the zero line: electricity that you have fed back into the grid.

• The line: the day-ahead electricity prices in the Netherlands.

These day-ahead prices are wholesale prices, excluding VAT and energy tax.

Your dynamic energy contract (for example with Energie VanOns) is based on these wholesale prices, with:

• A small supplier markup

• Including energy tax and VAT

In the new version of the app (expected in March or April), the full hourly price will be visible as you actually pay it to your energy supplier.

We expect to publish a renewed version of the EMS tab in the app in March or April, with clearer information and more extensive price transparency.
