A private individual who generates green electricity receives, by default, one green certificate for every 1,000 kilowatt-hours (kWh) of electricity generated, which reduces CO2 emissions by 217 kg. These certificates are awarded for 10 years, starting from the date of certification of the installation.
A 30 m² photovoltaic installation produces an average of 3,000 kWh per year in the Belgian climate. Theoretically, it therefore entitles the consumer to three green certificates.
These green certificates are awarded for 10 years starting from the date of certification of the installation. They are valid for 5 years.
For photovoltaic installations in Brussels, this benefit is increased by means of a multiplication coefficient.
Every year, the Brussels government decides the value of this multiplication coefficient, taking into account the average price of the panels, the price of electricity and the price of the green certificate:
Brugel recalculates the multiplication coefficients every year in September, in order to maintain a flat-rate return on investment of 7 years for photovoltaic panels and of 5 years for the eligible cogeneration installations. With this system, everyone has the guarantee that their installation will pay itself back in 7 years, regardless of when consumers decide to invest in these technologies.
Your generation is displayed on the special meter that you had to have fitted to your installation. Every quarter, submit the figures to Sibelga.be/greenmeter. Sibelga then sends them to Brugel, which allocates the green certificates you are entitled to.
Thanks to the green certificates, people who invest in green energy (photovoltaic) systems or less polluting (cogeneration) installations receive a subsidy proportional to the production capacity of their installation. This allows them to recoup their investment much faster.
Green certificates are a source of income that is not taxed if the production of electricity is limited to your personal consumption
To sell your green certificates in Brussels, you have 3 options.
To reach their minimum annual quota of green electricity sold in Brussels, suppliers sometimes have to buy green certificates on the market. If they fail to do so, they are fined €100 per missing green certificate.
In 2019, this quota was 9.2%, and this percentage increases every year. In addition, the energy suppliers in Brussels are obliged to buy green certificates from Brussels-based consumers first before they can buy them in other regions.
You can sell your certificates to any supplier active in Brussels, but bear in mind that some of them pay their own customers a better price.
Intermediaries are brokers who bundle green certificates from small producers and negotiate their sale with energy suppliers. Some PV installation companies offer this service to their customers.
Compare their offers carefully, as the buy-back conditions can be very different. Some take a commission on the sale, others buy your green certificates at a slightly lower price than the market price, etc.
A regulation allows you to sell your green certificates to Elia, the transmission system operator, at a guaranteed minimum price of €65 per green certificate. This is less interesting than the average prices offered by suppliers and intermediaries.
