Why is my injection compensation lower than my consumption price?

Suppliers charge a commercial margin and additional costs for electricity consumption. A different formula usually applies to electricity injection. As a result, consumption and injection prices are generally not identical.

Moreover, electricity generated by solar panels is often injected during periods with lower market prices. Across Belgium (and often throughout Northwestern Europe), many solar installations generate electricity simultaneously around midday. The increased supply drives spot prices down.

As a result:

• you produce the most electricity when market prices are often lowest;
• your injection compensation follows these lower market prices;
• prices may even become negative.

For many PV owners, the average injection price is therefore significantly lower than the average consumption price.
