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) are parties that take over the complex tasks related to meter registration, administration, verification, the booking, and trading of emission reduction units (EREs). Smaller companies that book less than 2 million kWh of electricity per year for transport, as well as private charging point owners, have been required to use an emission credit service provider since January 1, 2026.

The Dutch Emissions Authority (NEa) plays a central role in decarbonizing transport in the Netherlands and oversees the actual delivery and registration of renewable energy. Voltico is known as an emission credit service provider with the NEa and is authorized to book electricity on behalf of third parties in the Energy for Transport Register (REV).

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 name of the company. In the case of building leases, the landlord must grant a formal authorization allowing the tenant to benefit from the ERE credits.

• Only 100% subsidiaries can be included in the registration by the parent company. Subsidiaries are not allowed to register on behalf of their parent company. In that case, the subsidiary must issue a formal authorization to the emission credit service provider (inboekdienstverlener), such as Voltico, to act on its behalf.

• Due to audit costs, participation becomes profitable from 50 MWh (50,000 kWh) per year. For electric cars, the annual charging volume is approximately 3 to 5 MWh per vehicle. For electric vans, it is around 10 MWh, and for trucks, 100 MWh. We are happy to help you determine if your charging volume is sufficient.

• We perform an update on the charge points to enable energy consumption tracking. The functionality of the charge points, such as access via charge cards or tags, remains unchanged. If the charge points are managed by a third party, we will coordinate the required one-time update with your permission.

No. You don't need to charge your electric vehicles with 100% renewable energy to claim EREs.

Electric driving always results in CO₂ reductions compared to petrol or diesel vehicles, even when charging from the grid. Because a significant share of grid electricity is already renewable (on average 50.5%), this is taken into account when calculating emission certificates. Charging via the grid on a standard electricity contract therefore already generates recurring income through EREs.

That said, EREs linked to 100% verifiable renewable energy are worth twice as much. If you charge using your own renewable generation, such as solar or wind, and this can be proven to take place within the same hour as charging, higher-value EREs apply. Battery storage can also be used for this purpose. 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.

The income depends on the charging volume and the current ERE market price. As a rule of thumb, charging via the grid yields approximately €0.10 per kWh net. Charging with simultaneous on-site renewable generation, for example solar panels, can yield up to approximately €0.20 per kWh. This depends on the simultaneity between charging and generation, with or without a battery. Voltico optimises this automatically.

EREs are traded on the open market. The ERE price is determined by supply and demand and typically translates to between €0.05 and €0.15 per kWh net. Prices are not guaranteed. More information about ERE prices in this blog post.

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 the use of renewable energy in the transport sector by financially rewarding electric driving. Fuel suppliers buy them to comply with their legal sustainability obligations. As a result, money flows from fossil fuels to electric charging, CO₂ emissions decrease, and fossil fuel dependence reduces. The system rewards those who choose electric driving, and therefore contributes to more sustainable mobility.

From January 2026, emissiereductie-eenheden (EREs) replaced hernieuwbare brandstofeenheden (HBEs). This new system, which falls under the European RED III directive, introduces several important improvements. The ERE system focuses directly on actual CO₂ emission reductions across the entire transport chain. Its goal is no longer just to increase the volume of renewable energy, but to promote the forms of renewable energy that have the greatest impact on reducing total CO₂ emissions in the transport sector.

Yes, Voltico offers a co-branded portal for partners. Partners receive their own dashboard to manage and monitor clients, while each end client has access to an individual portal for insights, reporting, and payouts.

As an emission credit service provider, Voltico remains visible and accountable for ERE credits from a regulatory and compliance perspective. At the same time, partners fully retain the commercial relationship with their end clients. Voltico delivers the underlying infrastructure, software, compliance, and settlement, while partners stay in the commercial lead.

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.

Yes, absolutely. When charging can be proven to take place simultaneously with self-generated renewable energy (for example from solar panels), earnings can reach around €0.20 per kWh. This depends on the simultaneity between charging and generation.

When a battery is available, Voltico’s software can also account for charging powered via stored renewable energy. In that case, 100% renewable EREs can apply even if generation and charging do not occur in the same hour, provided this is supported by verifiable data.

Voltico’s software automatically optimizes this allocation. If you generate renewable energy on site, your emission credits can therefore be worth twice as much compared to charging with grid electricity. Our platform connects seamlessly with solar installations and smart batteries, synchronising all data in one place.
