What your charge point actually earns
You earn ERE’s on the electricity your charge point supplies to vehicles. Not on the power you use at home or in the office, and not on power you feed back to the grid: only on the kWh that actually go into a car or truck.
How many that is follows from three steps. Put simply: one ERE stands for 1 kilogram of CO₂ you save by driving electric instead of on petrol or diesel. More precisely: 1 kilogram of avoided CO₂-equivalent across the chain, measured against a European fossil reference value. For electricity that reference value is 183 grams of CO₂-equivalent per megajoule. And because far from all electricity is renewable, only the green portion counts.
That green portion is the crux. If you use ordinary grid power, the NEa cannot see which part of it was renewable. It therefore uses the grid-average renewable share: the proportion of green power in the grid. For 2026 that is 50.5%, set by Statistics Netherlands (CBS) on the basis of the Dutch share two years earlier.
What counts as 'supply to transport' is narrower than people assume. It concerns power that reaches a road vehicle through a metered supply point with a vehicle connection. Charging mobile machinery does not count (section 6), and swapping batteries does not either: it lacks the metered supply point with a vehicle connection that article 10 of the Besluit energie vervoer requires.
That 50.5% applies to everyone on grid power, business or private. Generate your own green power and supply it directly to transport? Then the full factor can apply, subject to conditions. More in section 4.
What an ERE is worth, and why nobody can quote you a price today
The most honest answer is also the most important, and it is not a number: there is no ERE price today.
The REV is closed and no ERE’s are being traded. A price only emerges once there is trading. Every amount per kWh circulating now, including ours, is therefore an assumption rather than a market quote. That is why our own page about the ERE price says in as many words that this is an assumed price.
That is not hedging; it is the state of play in August 2026. Anyone promising you a fixed amount per kWh now is making a claim about a market that does not yet exist.
What is settled is where the demand will come from. ERE’s are bought by fuel suppliers under a statutory fuel transition obligation (BTV): they must cut the greenhouse gas emissions of their transport fuels by at least 14.5% by 2030. That obligation is what gives an ERE its value. For illustration: under the former HBE system prices moved indicatively between roughly €8 and €19 per unit. That figure is not verified against a primary source and is moreover a different unit with a different basis of calculation. Read it as historical context, not as a forecast.
A worked example, with the assumption in plain sight
Do the sum with me. Take the kWh you supply to vehicles, multiply by the renewable share, convert kWh to megajoules (1 kWh = 3.6 MJ), multiply by 183 grams, and divide by 1,000. What is left is kilograms, and therefore ERE’s.
For a home charger supplying 2,500 kWh a year to the car: 2,500 × 0.505 = 1,262.5 kWh renewable. That is 4,545 MJ. Times 183 grams is 831,735 grams, divided by 1,000: 832 ERE’s a year, rounded.
| Charging volume per year | Grid power (50.5%) | Own generation (100%) | Indicative gross ERE value |
|---|---|---|---|
| 2,500 kWh (home charger) | ± 832 ERE’s | not applicable, see section 5 | ± €270 |
| 100,000 kWh (charging site) | ± 33,269 ERE’s | ± 65,880 ERE’s | ± €10,812 / ± €21,411 |
Indicative gross ERE value, calculated at the current market price of €0.32 per ERE (as of 16 Oct 2026): the amount before a service provider's fee. This is not a market quote, as the REV is still closed and no ERE credits are being traded. The outcome scales linearly with your charging volume.
For your own situation you can work it through with the ERE calculator. Two things to hold on to: the number of ERE’s follows directly from your charging volume and is therefore fixed, the amount in euros is not.
Grid power or 100% renewable: where the yield doubles
Grid power counts for 50.5%, own generation can count for 100%. That is close to a doubling of the number of ERE’s over the same charging volume, and the single largest lever a charging site has.
Two routes lead to that full factor.
| Route 1: generation on site | Route 2: direct line | |
|---|---|---|
| What it involves | You generate renewable electricity and supply it directly to transport on the same WOZ object | You generate on a different WOZ object and supply directly to the charging connection via a direct line |
| Location condition | Generation and supply on the same immovable property within the meaning of the Wet WOZ | The connection is at the supply location; the producer is a different entity from the supplier to transport |
| Evidence of origin | Non-grid GoO equal to the volume booked in, transferred to and cancelled at the NEa | Same |
| Metering | MID meter built into the charge point, plus a gross production meter with a green EAN code | Same |
| Subsidy | No operating subsidy over the booking period; a declaration from the RVO suffices as evidence | Same |
The two permitted routes to the full factor, with their conditions and evidence. Source: NEa and the Besluit energie vervoer. The additional requirements for the GoO and the gross production meter come from the Voltico white paper of May 2026, a first-party source.
Four conditions are the ones that most often trip people up in practice:
- Non-grid GoO. You need a guarantee of origin (GoO, the proof that your power is green) equal to the volume you book in, transferred to the NEa's account in the VertiCer register. The GoO is no more than a year old and the production address matches the claim address.
- Solar, wind and water only. Biomass, landfill gas and (sewage) biogas do not count towards the 100% claim.
- The meter inside the charge point. A separate MID meter in the meter cupboard is rejected. What applies exactly, and which transitional periods exist, is in MID certification and metering requirements.
- No operating subsidy over the booking period. A subsidy blocks the 100% claim, not the ERE’s themselves. That distinction matters more than it sounds: with an older SDE++ award you can still book in at 50.5% perfectly well. More on the page about ERE’s and subsidy.
A battery may serve as a buffer: generation and charging do not have to happen at the same moment. That is mainly of interest with a large-consumer connection carrying a gross production meter on solar, from a charging volume of roughly 100 MWh a year with comparable solar generation.
The solar panel myth: why home chargers always get the grid average
The biggest misconception in the market: if you charge at home with your own solar panels, you do not earn extra ERE’s. A home charger always books in at the grid average of 50.5%, however full the roof.
That does not come from us, but from a position taken by the Dutch Ministry of Infrastructure and Water Management: "A home charger can book in for supplies of electricity via a direct line, generation at the same location, or via the grid. Home chargers always go via the grid, which means the use of solar panels is not encouraged. Moreover, this is not the right instrument with which to encourage the use of solar panels."
Put simply: at home your solar power runs onto the grid and off it again through your regular connection. The routes in section 4 require a direct supply to transport, and at a residential address you cannot achieve that in practice. Your panels are not pointless: they lower your energy bill. They just will not raise your ERE yield.
For businesses generating on their own site the position is different. There both routes from section 4 are achievable, provided every condition is met.
What can block your yield
Three things depress your yield or make a booking fail:
- Netting is not allowed. You cannot offset renewable generation against your supply to transport across a whole year. You have to demonstrate that the electricity genuinely went to transport, and on an hourly basis at minimum. If you claim 100% at a charging plaza, you meter both the generation installation and any battery, and record in a metering protocol that this simultaneity holds. The NEa does not advise on individual cases.
- Feed-in does not count. Electricity you feed back to the grid cannot be booked in. If the power passes through a battery first, you must be able to demonstrate that it was supplied to vehicles after storage.
- Transport only. If you charge mobile machinery on the same infrastructure (a construction crane, a tractor, a telehandler), those kWh are not eligible. The regulation covers supplies to transport only.
Booking in yourself or through a service provider
Want to book in yourself? Then you need to reach 2 million kWh a year, or hold an account with a booking facility. Below that, it runs through an emission credit service provider. It collects your data, validates it, registers in the REV, trades the ERE’s and pays you out. For a provider booking in electricity from private individuals a different threshold applies: permission (authorisation) from at least 200 private individuals to book in on their behalf.
To put those 2 million kWh in perspective: that is roughly 800 home chargers, or one substantial logistics charging site. Most charging infrastructure in the Netherlands sits well below it.
The regulator's own figures show this. In 2025, 313 companies registered renewable energy, against 202 in 2024. Of those, 277 booked in renewable electricity, together good for 3.9% of all renewable energy booked in. Many participants, then, with little volume each. That is precisely why aggregation through a service provider exists, and it comes from the NEa itself.
What such a provider takes over is worth checking, because that is where providers differ. The chain runs from session data out of your charge points or charging management system, through validation against the NEa's requirements, registration in the REV and trading to a fuel supplier, to the payout to you. Any step can go wrong. And a booking that fails the annual verification probably pays out nothing: it is investigated first. Booking in is voluntary but not without obligation, because on rejection the NEa can determine the position of its own motion and demand correction.
So the question "what is the fee" weighs less than the question "what happens when a booking is rejected". A high gross amount per kWh means little if the underlying administration does not survive the check.
How registration works and what you need for it is covered in the step-by-step guide to ERE registration. Are you a private individual with a home charger? Then the route for private individuals is more specific. If you share a connection, for instance in a homeowners' association, read how an HOA with shared charge points claims ERE’s.
