Produce electricity and feed it entirely into the grid

The energy transition concerns us all

Feeding the electricity you produce into the grid allows you to make your installation profitable and earn an income. We will explain in detail the different elements to be aware of if you choose this option.

It is now very easy to produce your own electricity by setting up a photovoltaic system. This has several advantages: it allows you to contribute to the ecological transition by making available a completely renewable energy, and it also gives you the possibility to earn money, by reinjecting the energy produced into the grid.

Klimabonus” investment subsidy for your installation

Producing your own electricity is made even easier by the Klimabonus programme, which provides a range of investment grants for this type of project.

The installation of photovoltaic panels with a view to feeding the electricity produced back into the grid can also be made easier by obtaining investment aid. This aid can amount to 20% of the total investment, with a ceiling of 500 €/KWp.

Finally, note that if you choose to inject all the electricity produced into the grid, you can always change your mind and opt for self-consumption. However, a formal request must first be made to your grid operator at the appropriate time.

This applies to installations for which the invoice is issued by 31 December 2025 at the latest. The application forms for the financial aid will be available on guichet.lu. The aid can be applied for after the installation has been completed

Choosing your tariff model for the remuneration of the total energy fed into the grid

In addition to these practical elements, you will also have to choose between a guaranteed or flexible feed-in tariff model.

Option 1

By opting for the guaranteed feed-in tariff model, you benefit from a state-guaranteed feed-in tariff for a period of 15 years. You must conclude a feed-in contract with your grid operator.

Find out more about the upcoming state-guaranteed feed-in tariffs for installations from 0 kWp to 30 kWp below.

Option 2

If you opt for the flexible feed-in tariff model, you renounce the guaranteed feed-in tariff for the entire lifespan of the installation. You must conclude a feed-in contract with your energy supplier. The remuneration is a percentage of the wholesale market price, which varies monthly.

Steinergy offers you the market price (MW Solar) multiplied by a correction factor of 0.8, which takes into account the forecasting and price risks of the balancing energy.

If you are interested in a tailor-made offer based on market prices, waiving the state-guaranteed injection tariffs, please contact us at centrale.production@enovos.eu, specifying and adding the following documents to your request

  • Connection contract for the production facility from the grid operator
  • Grid usage contract from the grid operator

Caution: by opting for the flexible tariff, your remuneration can fluctuate significantly. Market prices are particularly volatile and are not the responsibility of the supplier. As an example, you will find below the average tariffs of the last few years, which are often lower than the guaranteed injection tariffs.

Please note that a photovoltaic installation also entails certain grid-related costs, as you will need a dedicated meter, for example. To see the tariffs of the different grid operators, click here (ILR).

Don’t forget your tax obligations

When you become an electricity producer, you can choose to be subject to VAT (and therefore be able to deduct it for certain operating expenses) or, on the contrary, benefit from the exemption system, if your turnover does not exceed 35,000 per year.

In both cases, you must register for VAT and file an annual VAT return, via MyGuichet for example.

Profits from the production of photovoltaic energy can also be taxed. However, this depends on your installation and the use made of the energy produced (self-consumption or total injection).

  • There is no taxation:
    • if you inject 100% of the electricity produced and you have an installation of less than 10 kWp;
    • if you are self-consuming without injecting the excess energy produced into the grid.
  • A tax is levied :
    • if you inject 100% of the electricity produced or if you have an installation of more than 10 kWp;
    • if you are self-consuming and inject the excess energy, a tax deduction is provided for depending on the level of self-consumption.

As a producer-seller of electricity, you can choose whether or not to be subject to VAT. Note that you will also be taxed on the income from the sale of your electricity, but only if your installation has a capacity of more than 10 kWp.

Photovoltaic installations > 30 kWp

For photovoltaic installations >30kWp, you can opt for one of the following two tariff options:

Option 1: State-guaranteed feed-in tariff

For your information, please find attached the current state-guaranteed feed-in tariffs for 15 years:

Option 2: Flexible feed-in tariff by a supplier (based on market prices)

If you are interested in a tailor-made offer based on market prices, waiving the state-guaranteed injection tariffs, please contact us at centrale.production@enovos.eu, specifying and adding the following documents to your request

  • Connection contract for the production facility from the grid operator
  • Grid usage contract from the grid operator
