Tibber + Joulo: a double win for EV drivers

We drive on Tibber ourselves. Two Teslas, two MID-certified chargers, one driveway in Brummen. Not sponsored, not paid • we write this because we use it ourselves.

Smart charging + EREs

Smart charging is exactly how driving electric should work. Your car charges at night at the cheapest moment, automatically, without you having to think about it. Tibber does that well: the app shows you what power costs per hour, the Pulse measures your consumption live, and smart charging handles the rest.

But there is another layer. On top of cheaper charging, those same charging sessions can earn you money back every quarter through EREs (Emission Reduction Units). That is what Joulo handles. The two complement each other perfectly.

Can I earn EREs on a Tibber contract?

Yes. Your energy contract • fixed, variable or dynamic • has no influence on your right to EREs. For private individuals, the Dutch Emissions Authority (NEa) always applies the national grid average share of renewable energy. That currently stands at 50.5%, regardless of what your supplier delivers.

Item	Value	Notes
Grid average 2026	50.5%	Renewable share • applies to all private EV drivers, regardless of supplier
Joulo service fee	20%	Tibber customers never pay more than 10%. Only charged when you actually get paid

Concretely: it does not matter whether you are with Tibber or any other supplier. Your ERE payout is the same for all private individuals • set by the grid average, not by your contract.

Dynamic rates and EREs: how does that work exactly?

The NEa does not look at your contract. They look exclusively at the national grid average of renewable energy. That has an upside and a downside.

Upside • You do not need to arrange anything around your energy contract. Tibber, green, grey, dynamic, fixed: all fine. Your ERE payout is the same.

Downside • You are not rewarded extra for charging exclusively on your own solar power, or for having a 100% green contract. Different rules apply to business drivers, who can take the actual energy source into account. For private individuals only the grid average counts.

This also means that as a solar panel owner you have no extra ERE advantage over someone without panels. The NEa acknowledges this is a point of debate, but it is how the law was written for the private market.

Charge cheaper and get money back

Tibber optimises your charging moment on price. Joulo registers those same charging sessions with the NEa automatically and makes sure you get your EREs paid out every quarter.

Two systems, one driveway. You do nothing • except charge.

Payouts run quarterly, and the scheme works retroactively: charging sessions from 1 January 2026 onwards count, even if you sign up only now.
