How does ePOWR and rPOWR work?

Discover how FlexiO contributes to grid balancing with a 'mega virtual battery' and optimises your energy installation. By being part of our Energy Community, you help stabilise the grid and receive compensation that accelerates your payback period. By being part of the Energy Community, you contribute 100% to the energy transition!

When the grid is out of balance, energy prices can be either very high or very low. This happens because there is either a surplus or a shortage of energy. Grid balancing ensures that the supply and demand for electricity are in equilibrium.

There are two types of grid balancing, each with their own characteristics. We’ll explain to you what the differences are between these types:

rPOWR - Reserved Capacity Grid balancing:

With rPOWR, FlexiO reserves a part from your battery for grid balancing services for our grid operators. In Belgium this is Elia.

This means that it doesn’t matter which energy supplier or tariff you have. Everyone can participate in this type of grid balancing.

👉 Here’s how rPOWR works:

• A small part of your battery is used as part of LIFEPOWR’s large “virtual power plant”

• Together with many other batteries, you help keep the grid stable.

• In return, you receive a share of the earnings.

💡 Important to know:

• Beforehand, it is checked whether participating in this type of grid balancing is worthwhile for you.

• If it’s financially better just to save on your energy bill → your system does not participate.

• This is continuously evaluated automatically (even minute by minute).

👉 Result:

• FlexiO always chooses what earns you the most, local optimisation or participation in gridbalancing.

ePOWR - Energy Market Grid balancing

With ePOWR, you can only participate if you have a compatible ePOWR Tariff. On our website, you can find a list with compatible ePOWR Tariffs to choose from.

We minimalise imbalance risk costs for the energy supplier. Therefore, the energy supplier is able to put a really competitive tariff in the market. See for yourself by doing the V-test.

👉 Here’s how ePOWR works:

• Energy suppliers need to predict every day how much electricity their customers will use, produce, and feed into the grid.

• These predictions are often inaccurate (they don’t have smart control using local measurements).

• Mistakes cost them money (so-called imbalance costs), which are eventually passed on to users.

• With ePOWR, we help them predict much more accurately what will happen at your home (up to 24 hours in advance).

• This allows the supplier to buy energy smarter and cheaper while you can enjoy from these benefits too!

💡 Important to know:

• As a B2C client, you can never be exposed to the risks of imbalance markets. LIFEPOWR will cover these costs, if they are made.

• If your system is not functioning as it should (for example, your system is offline), you are switched to a “fallback tariff” to make sure you’re not exposed to the imbalance market without smart steering. Ofcours you’ll get notified if this happens.

👉 Result:

• FlexiO always chooses what earns you the most, local optimisation or participation in gridbalancing.

• This way, you get the most out of your energy contract and pay the least for energy!
