Key takeaways about EREs
- EREs let you earn money from EV charging by selling certificates created from the electricity you use to charge your vehicle.
- New Dutch rules (from January 2026) allow homeowners and (smaller) businesses to participate more easily.
- Transparency matters: your earnings depend on the real sale price of EREs, not just the promised profit share.
- Experience matters: mistakes in verification or audits can mean no payout at all.
- Your CPMS or charge card provider is the safest partner, because they are the source of truth for charging data.
- Tap Electric handles verification, trading, and payouts transparently, so you can earn without regulatory complexity.
What EREs are and why they matter?
From January 2026, updated Dutch energy rules made it possible for homeowners and small businesses to earn money from the electricity used to charge electric vehicles at home or at work. This is done through Emission Reduction Units (EREs) — tradable certificates that represent verified renewable electricity used for transport.
Fuel and energy companies are legally required to buy these certificates to meet climate targets, creating a real and active market. As this market grows, transparency has become essential — not just in how EREs are priced, but in how they are verified, traded, and paid out.
Tap Electric enables participation in this market with transparency by design, handling regulation, verification, and trading while giving charger owners clear insight into how their EREs are managed.
How much are EREs worth?
The value of EREs is set by the market. Prices depend on supply and demand.
Current value
- At the moment, EREs trade at approximately €0.18 per kWh.
- This is the reference price used in Tap’s earnings estimates, but the actual price is always determined at the moment of sale.
Historic price range
- ERE prices have varied significantly over time. Based on market experience:
- Lowest observed levels: around €0.04 per kWh
- Typical recent range: between €0.15 and €0.20 per kWh
- Higher values: in specific cases, prices can be higher
In the below chart, we show the short recent history of ERE pricing since their introduction, vs the longstanding history of their predecessor, HBE credits.
What market pricing means for charger owners
EREs are not a fixed subsidy — they are a market-based incentive. Your actual earnings depend on:
1
The amount of verified charging (kWh)
2
Market prices at the time of sale
3
The type of charging location (home vs business, renewable sourcing)
This is why transparency around pricing and trading matters: understanding what EREs are sold for is just as important as how many you generate.
Solar energy and ERE value: what you need to know
In short:
Solar electricity ≈ double ERE value
Solar EREs currently require a business location and an on-site audit.
Electricity generated from on-site solar can generate roughly double the number of EREs per kWh compared to grid electricity. This is because solar electricity has a higher verified climate benefit under the ERE framework.
However, this higher value comes with strict conditions.
Solar EREs are currently limited to business locations
The authority has decided that, for now, only business locations can claim EREs based on on-site solar generation. This is in part because proving that a charging session was powered by solar requires an on-site audit, which typically costs several thousand euros. The authority has decided for simplicity that residential locations cannot yet qualify for this.
For residential charging locations:
- Charging is treated as using the net-average grid electricity mix
- As a result, residential charging does not qualify for higher-value solar EREs
How are EREs calculated from charging data?
EREs are not created simply by counting kilowatt-hours. Instead, they are based on the climate benefit of using electricity for transport.
In practice, this means:
- Charging data (kWh) is combined with standardised CO₂ reference values
- These values represent the emissions avoided by replacing fossil fuels with electricity
- The result determines how many EREs can be issued for a given amount of charging
For most charging locations, a net-average electricity mix is applied. This approach is defined by regulation and ensures consistent, auditable calculations across all participants.
For charger owners, the key takeaway is that accurate measurement and correct classification matter. Even if charging volume is high, errors in calculation or classification can reduce or invalidate the number of EREs issued.
How ERE trading actually works
EREs aren’t physical energy — they’re proof that electricity was used for EV charging, much like a digital certificate. Here’s how the process works in plain language:
- ERE contracting: a meter owner signs a contract with a service provider like Tap to manage their ERE credits.
- Measurement: your charger records the electricity you use — but only if it has a certified MID meter.
- Verification: That data is prepared and verified according to Dutch rules (REV framework).
- External audit: Tap and our partners work with the auditors from the Emissions Authority (NEa) to verify your credits. If the auditor finds any errors in the data, the ERE’s cannot be monetized. If fraud by a user is detected, this will be handled according to Dutch law.
- Certification: Once audited and approved, an ERE is created for every kWh of eligible charging.
- Trading: Tap lists these certificates on the market where energy and fuel companies buy them to meet their legal obligations.
- Revenue Share: When certificates sell, you earn most of the proceeds — Tap takes a transparent fee and you get the rest. The applicable fee varies by the length of registration you agree to: 1 year (24% fee), 2 years (22% fee) or 3 years (20% fee).
Because these certificates have real market value, your charging behavior becomes a source of revenue without affecting your electricity contract or how you charge. This transparency and market access is why EREs are a compelling new way to earn from EV charging.
Who can benefit: homeowners and businesses
Homeowners
To participate and earn:
- You must own the electricity meter at your home located in the Netherlands
- You must have an MID-certified charger — look for an “MID” marking on the charger or in the manufacturer specs.
- If you live in an apartment building, verify that the meter at which the charger is connected is uniquely yours. If the meter is owned by your VvE, only the VvE can claim the ERE’s as a business.
This ensures compliance with Dutch ERE rules and that you receive the full value of your charging data.
Businesses
Commercial charger owners can register multiple locations and chargers, making ERE earnings ideal for:
- Company fleets
- Workplace charging
- Customer charging stations
- VvEs
Tap’s platform supports both homeowners and business customers, offering centralised management and payout reporting.
Why transparency matters in ERE markets
ERE markets are still new, and most providers work on a profit-share model. This makes transparency essential — not just for trust, but for hard numbers.
If a provider claims you’ll get 75% of proceeds, but sells the certificates at lower prices in private trades or uses an opaque broker, your effective income can be much lower.
Charger owners should beware of service providers claiming that they can offer 100% guarantees on audits. The market is in its early days, the rules are still being worked out, and audits are never guaranteed. This is especially true for parties that are inexperienced in auditing, and provides them with a strong incentive to keep things intransparent for charger owners.
Tap’s approach uses a public ledger so you can see:
- Which credits passed the audit successfully
- When certificates were sold
- At what price
- How your share was calculated
This gives you confidence that you’re being paid fairly, and that the entire process — from verification to payout — is verifiable and audited.
Why experience matters in ERE trading
The ERE market is new, but the rules, audits, and consequences are not. Submitting incorrect or incomplete data can result in certificates being rejected — meaning no payout at all for charger owners.
For that reason, it’s important to choose a partner with proven experience in regulated energy markets, not just one that has recently entered the ERE space.
Bas Gerzon, Tap’s ERE booking partner, explains:
Bas Gerzon
Gerzon and his colleagues bring long-standing experience in regulated energy markets and compliance to Tap’s ERE offering. That experience helps reduce the risk of errors, audit failures, and lost revenue — risks that tend to be higher when working with new or inexperienced providers.
For charger owners, the takeaway is simple: EREs can be valuable, but only when handled by a partner that knows how to operate under regulatory scrutiny. In regulated markets like EREs, data integrity is not a nice-to-have — it’s a prerequisite for getting paid.
Why your CPMS or charge card provider should handle EREs
At the core of ERE trading is one thing: accurate charging transaction data.
Every certificate depends on knowing how much electricity was used, when it was used, and where it was used.
Your CPMS (Charge Point Management System) or charge card provider is the source of truth for this data. They record charging sessions directly, in real time, as they happen.
Using a third party that relies on:
- Manual data exports
- Periodic CSV uploads
- Indirect or unsupported integrations
adds extra steps between the charging session and the final booking.
Each step increases the chance of:
- Missing sessions
- Incorrect kWh values
- Mismatched locations or meters
- Data that cannot be reconciled during audit
Under ERE rules, even small inconsistencies can lead to rejected certificates or lost revenue.
For charger owners, the principle is straightforward: the closer your ERE partner is to the original charging data, the lower the risk. That’s why working with your CPMS or charge card provider — the systems already responsible for recording and validating charging sessions — is often the safest and most reliable approach.
