How long does it take?

Signing up takes 5 minutes. Joulo handles the NEa registration for you. Payouts happen every quarter.

What does Joulo do exactly?

We read your charger data, register your kWh with the NEa, have the data audited by an independent verifier, sell the EREs on the market and pay you out. All you need to do is charge. Service fee: 20% • as low as 10% via referrals.

How long does Joulo keep my ERE data?

Your charging sessions and ERE registrations are kept for at least 5 years from the calendar year of registration, as required by the Regeling energie vervoer. This allows the NEa to audit or correct a registration up to 5 years back. For invoices and payouts the fiscal retention period of 7 years applies.

Is this a lasting income source or a temporary scheme?

RaboResearch explains in a 20 May 2026 analysis that demand for ERE-Es from electric road transport will rise through 2030: the land subsector must achieve a 28.4% greenhouse-gas chain emission reduction, with a gap of roughly 13% that has to be filled primarily with ERE-Es and ERE-Gs. At the same time, the exact ERE price cannot be guaranteed in advance, and what applies after 2030 is not yet fixed. We use no fixed rates, only market price minus service fee.

What are ERE's?

ERE's (Emission Reduction Units) reward every kWh you charge at home: proven CO₂ savings • and you simply get paid for it.

A built-in MID meter on your charger is required for participation. Compare brands in the MID charger check, or run the charger check for your setup.

Joulo handles the entire registration as your ERE service provider. Curious how one charging session becomes a tradable credit? Read how an ERE credit is created. Want to start right away? See how ERE registration works at Joulo.

the calculation

How your earnings are calculated

Official NEa formula (RED III)

kWh × renewable% × 183 × 3.6 / 1000 = ERE's

Grid power

renewable: 50.5%

2,000 kWh → 665 ERE's

€260 net / year

Market price €0.49 per ERE • €0.16 gross and €0.13 net per kWh after 20% service fee. Actual market price is determined daily via OTC trading.

Why a MID meter?

To claim EREs, your charger needs a built-in MID-certified energy meter. Why? Because the NEa only accepts measurement data from a calibrated meter directly attached to the charger. This makes every kWh provable and tamper-proof. Want to know if your charger qualifies? Check it via our compatibility tool.
