Prosumer in 2021 and beyond

Starting in 2021, digital pros will be able to receive compensation for every kWh you inject back into the grid.

Are you having solar panels installed after 1 January 2021? Do you have an installation older than 15 years? Or have you already opted for the net tariff based on actual use? because you have already had a home battery installed or have a high level of self-consumption? self-consumption? Then you can now sell your surplus energy production to the to the electricity grid. In this article we explain how this works.

When you have solar panels installed in Flanders from January 2021, or when your installation is more than 15 years old, you will automatically fall under the net actual purchase tariff . This tariff structure is based on the actual use of the electricity network. You must have a digital meter. You need this to measure separately how much electricity you are taking from and injecting into the grid.

If your installation is younger than 15 years, you can also choose to choose to switch to this system, even though in principle you are still entitled to the entitled to the mechanism of the reversing counter (= balancing). You can do this You canapply for this at your grid operator (Fluvius). Please note that this transitional arrangement of the Flemish Government is currently being contested by the VREG before the Constitutional Court. A decision in this case is expected before the end of 2020.

Once you have opted for the tariff structure based on actual use, you can no longer you can no longer go back to the old system with the prosumer tariff. Please note that you will have to pay for a digital meter if you request one yourself.

In Brussels and Wallonia, the injection tariff system does not (yet) exist. does not exist.

How can I sell my power then?

If you have opted for the net tariff based on your actual consumption, you you pay on the one hand for the electricity you actually consume from the grid and on the other hand for the use of the from the grid and on the other hand for the use of the electricity grid (also when you inject electricity). you inject electricity). The new feature is that from now on you will also receive a (small) fee for your injection.

To do this, you have to conclude an energy contract that provides for a for your injected electricity: the electricity you produce but do not immediately use yourself. but do not immediately use. You place this surplus on the grid, and you 'sell' this You 'sell' this power to your energy supplier. In practice, you will always make the most of the money by using the electricity yourself. use the electricity yourself.

How does this work in practice?

  • For For every kWh that you buy from the grid, you pay for the electricity, the grid network costs and taxes. For most contracts, this price varies between 0.25 and 0,30 €/kWh.
  • For For every kWh that you have left over, you receive a compensation from your supplier. The The compensation will be shown on your bill. Please note, the contract with your supplier must provide for this. It is expected that the compensation will be approximately between 0.025 and 0.035 €/kWh. The reason for this low compensation is because you probably inject power into the grid when demand is very low. is low. For example, your solar panels produce the most energy around midday, but that is often the time when there is the least consumption in the house.

What does this mean for the payback period of my solar panels and my overall energy bill?

If you fall under the tariff structure based on actual consumption, then the payback period for your solar panels will be longer than payback period for your solar panels will be longer than under the old arrangement with the consumer tariff. In order to this, the Flemish government is providing a subsidy from 2021 onwards for new solar subsidy for new solar panel installations.

In order to reduce your energy costs anyway, it becomes very important to limit your use of the electricity grid to the minimum. The injection injecting electricity into the grid in order to take it away from it again later becomes injecting electricity into the grid in order to buy it again later becomes disadvantageous due to the large difference in cost of purchase (€0.25 to €0.30 per kWh). (€0.25 to €0.30 per kWh) and the yield of injection (approximately €0.03 per kWh).

So go for a large self-consumption or simultaneity between generation and consumption. You can do this by using your electricity immediately, for example by delaying the start of your dishwasher so that it starts up when the sun shines, or by charging your electric car smartly. In addition, an investment in a home battery becomes more interesting. By installing a smart home battery from AlphaESS alongside your solar panels, you can store your own produced energy for times when the sun does not shine.

Note that the Flemish premium for home batteries will be extended in 2021. Moreover you will be able to combine this premium with the new subsidy on solar panels. Close In addition, if you sign an energy contract that provides for compensation for your injected energy, then there is a good payback period for your own green power plant there certainly is. Even more important is that with solar panels in combination with an AlphaESS home battery with an AlphaESS home battery is a big step towards a greener world.
