Do you have solar panels? You can generate energy and sometimes feed in to the power grid. Feeding in energy causes costs for us as energy supplier. That's why we charge feed-in costs, an amount per kilowatt-hour (kWh) of energy that you feed in. On the other hand, you receive a feed-in tariff for your generated energy. On this page, we'll explain exactly how this works, what you pay, and what you receive.

Frequently asked questions

Questions Answers.
Questions Answers.

Do I have to pay for all energy that I generate?

No. You only pay for the energy that you don't use yourself right away and feed in to the power grid.

How does net-metering work?

You can offset the energy that you feed in with the energy you consume on the annual settlement or final settlement. That's called net-metering. Do you feed in more than you consume? You'll receive a feed-in tariff for the extra part. You pay feed-in costs over all energy that you feed in.

Where can I see how much I feed in and what it costs?

In your energy contract, your My Coolblue environment, and on your annual settlement or final settlement.

Do my solar panels still yield anything?

Yes. You save by using your own energy right away. You receive a compensation for the energy you feed in that's a little higher than the costs you pay for it.

I'm already a customer, will I also pay feed-in costs?

It depends on your contract. Do you have a fixed contract from before 17 October 2025? Nothing will change for now. Do you extend your contract after that or do you have a variable contract? You'll start paying feed-in costs per kWh.
