How many ERE's does 1 kWh of charging yield?

With grid electricity in 2026 about a third of an ERE per kWh: 50.5% renewable × 183 grams of CO₂ per megajoule × 3.6 megajoules. At 100% own generation about twice as many.

Why is there no fixed amount per kWh?

Because the ERE price is a market price that moves every week. So we always calculate with the latest published weekly price, with the date stated.

What costs are there besides the service fee?

As standard none. Verification, transaction costs, the broker and the platform are included in the service fee. Only if the verification body needs a site visit for 100% renewable, shore power, mobile machinery or temporary sites is €950 per location added.

58 days left to choose for 2026. Our advice: arrange it before 31 December. Get started for 2026

Calculation

Worked example: 10,000 kWh of grid electricity

A business with a few charge points charges 10,000 kWh a year from the grid. This is how we get to what it keeps.

Charging electricity
10,000 kWh, measured by the MID meter in the charger.
Renewable share
In 2026 grid electricity counts as 50.5% renewable (set by CBS, the Dutch statistics office). Electricity you generate yourself counts as 100%, under conditions.
ERE's
Every renewable kWh replaces fossil fuel at 183 grams of CO₂ per megajoule, and a kWh is 3.6 megajoules. 1 ERE stands for 1 kilo less CO₂ emitted in the chain. Together: 3,326 ERE's.
Market price
Fuel suppliers buy your ERE's at the market price. It moves; the ERE price index shows it weekly, as of 16 Oct 2026.
Minus the service fee
We keep a service fee on what your ERE's earn: 20% on the first €10,000 of revenue a year, then stepping down to 6%. Private individuals always pay 20%. No upfront costs.
