Booking 100% renewable: business only, and only with Guarantees of Origin

Does your fleet charge on your own premises, with your own solar panels on the roof? Then the thought is logical: that electricity is 100% renewable, so those kWh should earn double the ERE credits (emission reduction units). That is possible. But only under conditions the Regeling energie vervoer prescribes precisely. Here they are, with what the NEa really requires.

Why the grid average is the default

The regulation counts every kWh that enters through a grid connection against the renewable share of the Dutch grid as a whole: 50.5% in 2026. Behind the meter, an electron is an electron. Whether that kWh came from your roof or from the grid cannot be seen in the booking. That is why one fixed share applies to grid supply.

For a private home charger the story ends here. That route to 100% does not exist for a household, not even with panels. Why that is so is in Do your solar panels count for ERE when charging at home? (in Dutch).

The 100% route is for businesses

Article 9, paragraph 3 of the regulation sets one condition for counting self-generated electricity above the grid average. That electricity must be greened in the books with Guarantees of Origin for non-grid supply. The two situations where that is possible are in article 10, paragraph 3:

• A direct line: your own cable from a generation installation to the charging point, outside the public grid.
• Generation at the company's address: electricity generated at the company's address and intended exclusively for that one supply point.

The word company is there for a reason. This is a route for business sites, fleets and offices with their own generation.

The four conditions

1. Generation at the same supply site

The generation installation and the charging point are at the same address, or are connected by a direct line. Electricity from an installation elsewhere, settled through the grid, does not qualify.

2. Metered data that closes the chain, per hour

The NEa requires you to prove with metered data how much was generated and that the generated electricity actually went to transport. As soon as the installation also feeds back to the grid or powers other equipment, that has to add up per hour. In practice that is almost always. Per hour only the smaller of two numbers counts: what you generated and what you charged. What you fed back to the grid in that hour never counts.

The regulation currently sets no separate meter type requirement for the generation meter. We do apply a minimum: a MID-certified meter on the generation installation, readable and verifiable for the verifier. Inverter data is not a meter, and the verifier has to find something verifiable during the site visit.

3. Guarantees of Origin for non-grid supply, cancelled before booking

This is the condition that gets skipped most often. The generated electricity must be greened in the books with Guarantees of Origin for non-grid supply. You apply for those at VertiCer, and they must be transferred and cancelled at the NEa before the booking. Without those Guarantees of Origin the electricity counts as grid supply, however green the roof.

Note the difference with the Guarantees of Origin of your energy supplier. Those belong to electricity from the grid and say nothing about your own generation. A green energy contract therefore does not get you to 100%.

4. No operating subsidy on the generation you book

No operating subsidy such as SDE++ may have been received on the amount of electricity you book as 100% renewable. The verifier checks that during verification. This condition only matters for those who use this route. If you simply charge on grid electricity, it does not apply.

What it yields per hour

The booking is split. The kWh that were demonstrably generated and charged in the same hour count as 100% renewable. The rest of the charging session counts against the grid average. Over the matched part your ERE credits almost double; over the whole charging volume they do not.

An example: on a summer day a fleet charges 400 kWh, of which 150 kWh between 10:00 and 16:00 while the panels delivered 180 kWh. Those 150 kWh count as 100% renewable. The remaining 250 kWh count against 50.5%. If the fleet mostly charges at night, there is little left to match.

A battery between generation and charging point does not make it simpler. If it is connected to the grid, you have to track per hour which part of the battery's contents comes from your own generation. Every incoming and outgoing flow has to be metered. That is possible, but it requires systems that really deliver that telemetry.

Three claims to distrust

If you come across one of these promises, ask further:

1. "Charging on solar power? Then we book that separately as 100% renewable." For a household that route does not exist. For a business only with the four conditions above.
2. "Green ERE credits yield about double." Only over the kWh matched per hour, and only with Guarantees of Origin for non-grid supply. Without those two, the number is the grid average.
3. "With your green energy contract you count as 100%." Your supplier's Guarantees of Origin belong to grid supply. They do not change the share of your charging sessions.

A booking that rests on such a claim does not survive verification. The NEa can correct up to five years back, and the registration provider is liable for that.

How we set this up

The 100% route is custom work. Per site we look at whether the four conditions are feasible, which meter goes on the generation and how the Guarantees of Origin flow. We split the booking per hour into a green part and a grid-mix part. Hours without conclusive metered data we count against the grid average. Better a smaller number that holds than a bigger number that gets reversed.
