Zeres
For businesses & HOAs

Fleet, charging plaza or HOA garage? We turn it into EREs.

Zeres combines 15 years of experience with business solar and charging infrastructure with 4 years of expertise in CO₂ emissions certificates. We read out automatically, include your PV energy, register with the NEa and trade on the emissions market ourselves.

What we do

From charger to payout

Automatic reading

Through OCPP and APIs we connect directly to your chargers or back-office provider. Available for 90+ brands.

Include PV energy

Self-generated solar energy counts 100% vs. ~50% for grid electricity — more than 2× as many EREs per kWh.

Register with NEa

We register and report the full volume with the Dutch Emissions Authority.

Trade on the market

No middleman: we sell your EREs ourselves on the emissions market for maximum revenue.

Quarterly payout

Self-billing invoice + detailed report per payout. Retroactive from January 1, 2026.

Annual audit

Mandatory NEa audit performed by our Compliance Officer (€ 150 ex VAT; waived >50k EREs).

Calculation example

16 AC charging points, 100,000 kWh per year

Say you have 16 charging points of 11 or 22 kW. 250 working days per year × 1 session per point × 25 kWh average = 100,000 kWh. That yields approximately 33,000 EREs. At a market price of € 0.45 and 16% commission you receive net approximately € 12,500 per year.

Without solar
€ 12,500
net per year
With PV system (100%)
€ 25,000
net per year — more than 2× as much

Per 1,000 kWh: approximately € 125 with only a grid connection, almost € 300 with a solar energy system. In our quote we calculate your exact situation.
