What are EREs?
EREs (Emissiereductie-eenheden, or Emission Reduction Units) are tradeable certificates issued under a scheme managed by the Dutch Emissions Authority (NEa). The system has been in place since 1 January 2026, replacing the previous HBE framework.
The core principle is straightforward:
Every kilowatt-hour charged into an electric vehicle represents a measurable reduction in CO₂ emissions compared to fossil fuel use
One ERE equals one kilogram of avoided CO₂ emissions in the transport chain
Fossil fuel suppliers in the Netherlands are legally required to offset a portion of their emissions by purchasing these certificates
That purchasing obligation is what creates the revenue stream. The money flows back to the party that registers the charging sessions — in this case, Tibo Energy on behalf of your site.
Why the source of your electricity matters
Not all charging sessions generate the same number of EREs. The renewable fraction of the electricity used for charging directly affects how many EREs each kilowatt-hour produces:
Grid electricity counts as 50.5% renewable in 2026
On-site solar electricity counts as 100% renewable
A higher renewable fraction means a higher CO₂ reduction factor per kilowatt-hour, and therefore more EREs generated per session. Solar-backed charging is significantly more valuable under this scheme.
What infrastructure is required to qualify
To register solar-backed charging sessions as verifiably renewable — a legal requirement for claiming the higher ERE rate — two things need to be in place:
A Gross Production Meter (Bruto Productiemeter) on your solar installation. This measures total solar output and proves the origin of the energy in a way that is admissible for ERE registration.
MID-certified meters integrated into your EV charge points. MID certification is a legal requirement for ERE registration and ensures session data meets the required standard.
Tibo Energy can help you confirm whether your site already meets these requirements and advise on any adjustments needed.
How Alice optimises your ERE yield
Alice, Tibo Energy's energy management platform, actively works to increase the ERE value of your charging sessions. Rather than allowing surplus solar energy to flow back to the grid at a low feed-in tariff, Alice prioritises routing solar kilowatt-hours directly to your EV chargers — or via battery storage as an intermediate buffer — so that as much charging as possible is backed by verifiable solar energy.
There is one exception to this logic: when spot prices are exceptionally high and exporting energy to the grid becomes significantly more profitable in that moment, Alice factors this into its decision-making and may shift priority accordingly. The goal is always to optimise total site revenue, not to maximise any single income stream in isolation.
What you need to do
For most customers, nothing. Tibo Energy handles the full process in the background:
Registration with the recognised booking service provider
Collection and submission of session data
Ensuring ERE revenue reaches your account
There is nothing to configure or manage manually. If you want to check whether your site is set up to generate EREs, or if you are considering infrastructure changes to qualify for the higher solar-backed rate, contact your Tibo Energy account contact directly.
