Frequently asked questions

ERE stands for “Emissiereductie-eenheid” (Emission Reduction Equivalent). One ERE represents one kilogram of CO₂ that was not emitted thanks to electric driving instead of driving on petrol or diesel. Fuel suppliers must hand in a legally fixed number of these EREs each year to comply with their sustainability obligations. More information can be found on the website of the Dutch Emission Authority.

Companies with their own charging stations* that provide electricity to vehicles, such as logistics companies, real estate locations, offices and fleet owners, are eligible. With at least 10 charging stations, it is usually profitable.

* The grid connection for the location with charging stations must be in the name of the (parent) company.

Emission credit service providers (in Dutch, inboekdienstverleners) handle the complex tasks around metering, administration, verification, registration, trading and payout of emission reduction units (EREs). Companies booking less than 2 million kWh per year for transport, and private charging point owners, have been required to use one since 1 January 2026. The Dutch Emissions Authority (NEa) supervises the delivery and registration of renewable energy.

Voltico is a recognised emission credit service provider with the NEa, authorised to register electricity on behalf of third parties in the Energy for Transport Register (REV). For a provider registering on behalf of natural persons, such as home chargers, an alternative threshold of 200 authorizations applies instead of 2 million kWh.

Voltico works on a no-cure, no-pay basis: you only pay a fee when your EREs are actually sold. Our fee is 20% of the realised proceeds. Volume-based tiers are available for larger portfolios.

There are no fixed monthly costs. Any one-time onboarding fee is deducted from your first payout, so there's nothing to pay upfront.

The grid connection must be registered in the company's name. If you lease the building, the landlord issues a formal authorization allowing the tenant to claim the ERE credits. Only wholly owned (100%) subsidiaries can be included by the parent company; a subsidiary may not register on behalf of its parent. Because of audit costs, participation is usually profitable from 50 MWh (50,000 kWh) per year.

If a subsidiary registers itself, it issues its own authorization to the emission credit service provider, such as Voltico. As a volume indication: an electric car charges roughly 3 to 5 MWh per year, a van around 10 MWh, and a truck 100 MWh. We are happy to help you determine whether your charging volume is sufficient.

To record energy consumption we perform a one-time update on the charge points. Their functionality stays unchanged, including access via charge cards or tags. If a third party manages the charge points, we coordinate that update with your permission.

No. You do not need to charge with 100% renewable energy to claim EREs. Electric driving always reduces CO₂ compared with petrol or diesel, including when charging from the grid. Because a significant share of grid electricity is already renewable, on average 50.5%, that share is included in the calculation. Charging from the grid on a standard electricity contract therefore already generates recurring income.

EREs linked to 100% verifiably renewable energy are worth twice as much. If you charge using your own generation, such as solar or wind, and this demonstrably happens within the same hour as the charging, higher ERE values apply. Battery storage can be used for this too. Voltico's system verifies and optimises this automatically.

No, Voltico offers a fully automated and compliant solution. There are no operational changes required. Technical integration is lightweight and typically completed quickly. We can perform a one-time, over-the-air update for your chargers and handle all administration, trading, and reporting. After onboarding, the process runs in the background without much ongoing effort from your side.

Income depends on your charging volume and the current ERE market price. As a rule of thumb, charging via the grid yields approximately €0.10 per kWh net. If you charge while generating on site, for example with solar panels, this can rise to around €0.25 per kWh. Voltico optimises that allocation automatically. Prices are not guaranteed and no rights can be derived from these indications.

The doubling with on-site generation depends on the simultaneity between charging and generation, with or without a battery. How the ERE price is formed is explained in our blog post on ERE prices.

In the Netherlands, fossil fuel suppliers are legally obliged to obtain a prescribed number of emission credits annually (EREs). In doing so, they contribute to the financing of renewable energy in the transport sector. This system is part of European regulations and anchored in national laws and regulations.

Through Voltico, your company can easily benefit from EREs. Traditionally, this can be difficult due to complex administration, regulations, lack of experience and difficult market access, especially with small trading volumes.

ERE certificates encourage renewable energy in transport by financially rewarding electric driving. Fuel suppliers buy them to meet their legal sustainability obligations. As a result, money flows from fossil fuels to electric charging, CO₂ emissions fall, and dependence on fossil fuels decreases. The system rewards those who choose electric driving and so contributes to more sustainable mobility.

From January 2026, emissiereductie-eenheden (EREs) replace hernieuwbare brandstofeenheden (HBEs). This new system falls under the European RED III directive and targets actual CO₂ emission reductions across the entire transport chain. Its goal is no longer only to increase the volume of renewable energy, but to promote the forms with the greatest impact on total transport CO₂ emissions.

Yes, Voltico offers a co-branded portal for partners. Partners receive their own dashboard to manage and monitor clients, and each end client has an individual portal for insights, reporting and payouts. As the emission credit service provider, Voltico remains visible and accountable for the ERE credits from a regulatory and compliance perspective.

Partners fully retain the commercial relationship with their end clients. Voltico delivers the underlying infrastructure, software, compliance and settlement, while the partner stays in the commercial lead.

Your payout is the number of registered kWh multiplied by the net ERE yield per kWh at the moment of sale. For grid charging that is approximately €0.10 per kWh as a rule of thumb; with simultaneous on-site generation it can rise to around €0.25. Prices are not guaranteed and no rights can be derived from these indications.

EREs are traded on the open market, where supply and demand set the price; that typically works out at €0.05 to €0.15 per kWh net. Proceeds are managed through a third-party account, separated from Voltico's own account.

You don’t need any additional hardware if your charging data is measured via certified meters. This applies when your charger is MID-certified, or when chargers are connected through a secondary allocation point (SAP) that exclusively measures charging activity. Voltico is fully software-based, and flexible API endpoints allow seamless data exchange with chargers, smart batteries, and solar panels. No hard- or software modifications required. We work with leading CSMSs, OEMs, and MSPs to ensure a scalable and reliable setup.

Voltico’s software integrates seamlessly with most existing systems and charging points, whether public, semi-public, or private, across one or multiple locations. It is compatible with AC and DC chargers, as well as commercial and residential solutions. If you’d like to check whether your chargers are eligible, contact us or schedule a short call.

Your income is set by two factors: the number of kWh you charge and the market price of ERE certificates at the moment of sale. EREs are traded on the open market, where supply and demand determine the price. That typically translates into a net value between €0.05 and €0.15 per kWh. Prices are not guaranteed.

For companies, charging with simultaneous on-site generation, for example from solar panels, can increase the value per kWh. Voltico can optimise that allocation automatically. More on price formation is available in our blog post on ERE prices.

ERE certificates are digital proof of the amount of CO₂ you save by driving and charging electrically compared with a conventional car. From January 2026, the certificates you earn per kWh charged make that CO₂ reduction visible, measurable and tradable. Companies are required to obtain sufficient EREs, which is what rewards clean transport.

In this way the system rewards your contribution to sustainable mobility and helps the entire transport sector become more sustainable.

Yes. When charging is demonstrably powered by on-site generation such as solar panels, the yield can double to around €0.25 per kWh. With a battery, Voltico's software can also count stored self-generated energy towards 100% EREs. This requires robust substantiation with verifiable data, which is checked during verification. The software optimises this allocation automatically. No rights can be derived from these price indications.

Four legal requirements apply for 100% EREs:

• Gross Production Meter (BPM). Inverter data alone does not meet legal requirements. Cost around €2,000 including installation, depending on the situation, plus a meter data subscription.

• Hourly charging session data. kWh consumption must be recorded on an hourly basis.

• Guarantees of Origin (GvOs). Submitted annually via the Verticer portal.

• Minimum charging volume. This setup is viable from approximately 100,000 kWh charged and generated per year.

Voltico integrates directly with solar installations and smart batteries. Get in touch to discuss the options for your situation.
