Dutch electric-car owners who charge at home and have solar panels will earn fewer ERE credits than many expected, and some will earn none. The Dutch Emissions Authority (NEa), which supervises the scheme, says a household may not book more charging electricity in a year than it draws from the grid on balance: what it takes from the grid minus the solar power it feeds back.
The rule appears in the NEa's questions and answers on booking electricity. The energy comparison site Keuze.nl reported it on 30 October, saying the authority made it clear at the end of October. Until then, Keuze.nl writes, booking services, calculators and Keuze.nl itself had counted every kilowatt-hour charged.
How home charging earns money
ERE stands for emission reduction unit (emissiereductie-eenheid). Fuel suppliers buy these certificates to meet Dutch targets for renewable energy in transport. Since 2026, electricity delivered to cars at home qualifies too. According to the NEa's page for private owners, owners can claim only through a booking service (inboekdienstverlener), and only with a home charge point that has an integrated, MID-certified kWh meter. The standard Tesla Wall Connector has no certified meter; Tesla launched a variant with one in the Netherlands in September 2025, priced at €570. Booking service Joulo identifies it by a part number starting 1529455-5.
Private owners are credited only for the grid-average renewable share of their electricity, regardless of a green-power contract or solar panels on the roof. Keuze.nl puts that share at 50.5% in 2026. A solar owner therefore already earned the same credit per kilowatt-hour as a neighbour without panels. Now there is a cap on top.
The NEa's own example
| Household | kWh per year |
|---|---|
| Drawn from the grid | 2,500 |
| Generated by solar panels | 3,000 |
| Fed back to the grid | 500 |
| Charged into the car | 3,000 |
| Bookable for ERE credits | 2,000 |
The bookable volume is 2,500 minus 500. The other 1,000 kWh of charging, although measured by the charge point, earns nothing. A household that feeds back as much as it draws over the year can book nothing at all.
Shifting charging into sunny hours does not change the result. Over a year, grid draw minus feed-in comes to the household's total consumption minus its solar output. Features such as the Charge on Solar mode Tesla added to the Wall Connector move the timing of charging, not the cap.
What it costs owners
Keuze.nl values the credits at about €0.15 per kWh charged before the booking service's commission, as of 30 October; what an owner keeps depends on the service. On that basis, a driver who charges 3,000 kWh a year at home, about 15,000 km of driving, loses €150 a year in the NEa example. If the household feeds back as much as it draws, the loss is the full €450. Keuze.nl, citing the 2025 National Charging Survey (Nationaal Laadonderzoek), says nine in ten home chargers have solar panels.
For scale, Dutch households paid an average of €0.2440 per kWh in the first half of 2026, according to Eurostat's latest figures.
Not written into the law
Keuze.nl notes that the cap does not appear word for word in the Besluit energie vervoer or the Regeling energie vervoer, the rules that govern the scheme. They say an owner books what the charge point's meter measures; the NEa derives the cap from how the rules are built. Owners who have signed up with a booking service, or counted on a payout, should ask how that service applies the cap.
