MyPOWR Price: Q&A

It’s very simple. On the home screen of the myFlexiO App, you’ll see your MyPOWR Price along with the average market price for the same period. The difference between these two numbers shows the net benefit you’ve gained from your complete system (solar panels, battery, EV, tariffs, FlexiO, etc.).

If you then multiply this difference by your energy consumption for the same period, you get a clear view of what your smart system has delivered for you.

Example:

• My MyPOWR Price for 2025: €0.151/kWh

• Average market price: €0.272/kWh

• Energy used during this period: 8,563 kWh

• Total benefit from my system: (0.272 €/kWh − 0.151 €/kWh) × 8,563 kWh = €1,036.12 saved

The price you ultimately pay per kWh of electricity consists of four main components. Suppliers only have partial control over this price.

1. Energy Price (± 40–50%)
   This is the price of the electricity itself.

   • Determined on the wholesale market (supply and demand across Europe)

   • Strongly influenced by:

     • gas prices

     • availability of nuclear, wind, and solar energy

     • international markets

   • Based on an average variable contract in Belgium

   ➡️ This is the only part where suppliers truly compete.

2. Network Charges (± 25–30%)
   These are the costs for transport and distribution of electricity.

   • Set by the network operators

   • Regulated by the government

   • Same rates for all suppliers in the same region

   • In Flanders, the capacity fee plays a major role. To reflect this accurately for your situation, we include the exact cost in your average energy cost calculation.

   • In Wallonia, variable DSO tariffs are significant and are included if you are a user in Wallonia.

   ➡️ Suppliers have no influence over these costs.

3. Taxes and Levies (± 20–25%)
   Government charges, such as:

   • federal and regional contributions

   • energy funds

   • VAT

   ➡️ Legally fixed and the same for everyone.

4. Supplier Costs and Margin (± 5–10%)
   This includes:

   • administration

   • customer service

   • billing

   • a small profit margin

   ➡️ Often a smaller part of the total kWh price than customers think. Differences between customers can occur here, which is one reason why the estimated energy bill may never match your actual bill exactly.

LIFEPOWR measures precisely how much energy is drawn from or fed into the grid through your meter and can therefore provide a reliable estimate of the energy cost your supplier will charge.

This amount is not an exact copy of your bill, because LIFEPOWR does not know all contract details (such as promotions, fixed subscription fees, or temporary discounts). The result is therefore a realistic approximation.

Additionally, your energy supplier uses monthly meter data directly from your electricity meter, which can also create slight differences.

If your FlexiO system sometimes loses connection to our server, your inverter, or the digital meter, we may “miss” certain data points that affect the estimated energy bill.

If you notice a large difference (more than 20%) between our estimate and your actual bill, it may be due to incorrect settings in FlexiO, or your system going offline or losing connection to your inverter.

In that case, first check your energy tariff in the myFlexiO App. If it’s set correctly, contact our helpdesk at 03 / 377 42 56.

No two months are the same. Your energy price is influenced by several factors: how much energy you generate with your PV system, how much you consume, and the income LIFEPOWR can generate for you through ePOWR and rPOWR.

It’s therefore completely normal for your energy price to be higher in winter than in summer. In summer, you generate a large part of your electricity yourself, and that energy is free.

By having your system smartly controlled, your MyPOWR Price is always well below the market price. At a glance, you can also see how well your system is performing.

The figure below clearly shows how the MyPOWR Price (green) changes throughout the year, based on production, consumption, and market income. The yellow line shows the average market price you would have paid if you didn’t have a smart energy system installed.

If you have a large system with relatively low energy use, you can generate a significant surplus during the summer months. FlexiO will sell this surplus smartly (at the right time) to your energy supplier.

Combined with rPOWR and ePOWR, this can result in your total energy bill for a given summer month being negative—in other words, you get money back from your energy supplier.

The MyPOWR Price is calculated by dividing your estimated energy bill by the energy you used that month for your comfort.

So, when your energy bill shows a negative amount, your MyPOWR Price will also be negative.

LIFEPOWR measures the actual energy use in your home: the total amount of energy you need for your daily life.

Your energy supplier, on the other hand, only sees how much energy you draw from or feed into the grid, because they only have the readings from your electricity meter. If you have a PV system and/or battery, this is inherently different from your actual consumption.

Example:

Suppose your home uses 500 kWh of energy for daily needs. Thanks to your PV system and battery, you only need to draw 200 kWh from the grid.

Your energy bill will show 200 kWh, because that is the energy you actually purchased from the grid. In reality, you used 500 kWh, much of which was generated by yourself.

If you notice a sudden and sharp increase in your MyPOWR Price, this may indicate an issue with your system.

LIFEPOWR continuously performs various checks and tests to ensure your system is operating correctly. However, if a problem occurs with your inverter, battery, or internet connection, FlexiO cannot automatically intervene. This can result in a higher MyPOWR Price.

Your MyPOWR Price also serves as an overall health indicator for your system. This helps prevent your installation from underperforming for months without you noticing.

If you see a MyPOWR Price that doesn’t follow the expected pattern, please contact our helpdesk. They’ll gladly review your system with you.

In short, MyPOWR Price is not just a price indicator—it’s also a practical tool to check that your entire energy system is performing optimally.

Great to see your enthusiasm! The MyPOWR Price charts will only appear one month after activation in the app, because we first need to collect some data.

If your savings are low, it’s usually due to an issue with your system or its configuration. This could be caused by a temporary internet outage of your FlexiObox, your inverter going offline or becoming uncontrollable, and similar issues.

There’s no need to panic—systems can occasionally go offline or need a reset.
