Earn and save with smart charging.
Charging your car for less and getting compensated for using sustainable electricity on top? With Stekker this is possible – and you’re not locked in.
How to earn with your charger.
Every kWh you charge at home can earn you money in three ways. Stekker handles all three — registration, market, payout.
Stekker shifts your charging sessions to hours with low energy prices and more sun. With a dynamic contract or solar panels, you save directly on your energy bill.
Every kWh you charge generates Emission Reduction Units (ERE’s). Stekker registers and trades them with the Dutch Emissions Authority and pays you 85% of the proceeds.
When the grid operator needs it, Stekker adjusts your charging power. You receive a fixed annual fee — you barely notice, your car is just ready on time.
How much will you earn?
Same calculation logic as the calculator above, worked out in three concrete scenarios.

The commuter
The home worker
Two minutes, then Stekker does the rest.

How does smart charging with Stekker work?
What is Stekker?
Stekker has been a smart charging expert since 2018. We control your charging station to charge for as little money as possible, while arranging an ERE compensation from the Dutch Emissions Authority (NEa) for every kWh you charge. For consumers, and for businesses balancing whole charging plazas.
What is smart charging?
Smart charging means your charger automatically charges at the right moment, rather than the moment you plug in. The right moment can be: when solar production is at its peak, when electricity prices are lowest, or when the grid has room. Stekker does this in the background — you only indicate when the car needs to be full.
Smart charging on solar
Got solar panels? Then your charger waits to charge until your panels are producing enough — filling your car with your own electricity instead of expensive grid power. What you produce yourself is always cheaper than what you buy. Stekker automatically matches charging rate to live solar output.
Smart charging on dynamic prices
With a dynamic energy contract, the electricity price changes every quarter-hour. Sometimes electricity is very cheap (during the day with lots of sun, at night with lots of wind), sometimes expensive (evening peak). Stekker automatically charges at the cheapest moments within your deadline. A typical saving is €0.04–€0.12 per charged kWh.
Absorbing peaks on the grid
The electricity grid is at its limit in many places. When the grid operator needs it, Stekker briefly adjusts your charging rate — you barely notice, your car is ready on time. For that flexibility you receive a fixed congestion compensation (~€35 per year). For businesses with multiple charging points, it also means: more charging points without grid reinforcement.
What are ERE’s?
ERE stands for Emission Reduction Units — tradable certificates that the Dutch Emissions Authority (NEa) issues for every kWh charged electrically instead of driven on fossil fuel. Fuel suppliers are legally required to purchase them to offset their CO₂ emissions. Stekker registers your charged kWh’s with the NEa and pays the proceeds to you.
I need a technical smart charging solution
For businesses controlling whole charging plazas, or suppliers wanting to offer smart charging to their customers, Stekker has a separate proposition. We control hundreds of charging points simultaneously within your contracted grid capacity, with grid signals and market prices. White-label via Embedded Solutions, or via a direct EMS integration.
