What does home charging earn with ERE? A per-kWh and per-year example

"How much can I earn by charging at home?" is the question we get most. Here is an honest answer, with a worked example you can check yourself.

How the amount is built up

Three steps:

1. Your kilowatt-hours charged at home are converted into ERE's, based on the grid-average renewable share (50.5% in 2026) and the CO2 reduction factor from RED III.
2. Those ERE's have a market value, which moves with supply and demand.
3. Your registration provider's service fee comes off that. What remains is your net revenue.

In the end that averages out to an indicative price of around €0.13 per kWh net • after service fees, market-dependent.

Worked example per year

Assuming that indicative price (mid scenario), and charging at home on your own connection:

You drive	Charged at home	Net per year (indicative)
15,000 km	about 3,000 kWh	about €390
20,000 km	about 4,000 kWh	about €520
25,000 km	about 5,000 kWh	about €650

The amounts are indicative and move with the market. If you charge partly in public or at work, only your home-charged share counts.

What makes it higher or lower

• The market price of an ERE. It fluctuates; that is why we work with an indicative price and a range, not a guarantee.
• How much you charge at home. More home charging means more ERE's.
• Your service fee. With Joulo 20% as standard, and down to 10% through referrals • a lower fee means higher net revenue.
• Private or business. Households use the grid average; business locations can come out higher under conditions.

Honest about "green"

Even with solar panels, the NEa uses the grid-average renewable share for a household, not 100%. That is not your provider's choice • it follows from the regulation. So we do not promise a 100% payout that is not there.

Work it out for yourself

Enter your own kilometres or kilowatt-hours with the calculator. It shows the current range and matches what you later see in your dashboard. More background is in what ERE certificates are.

Frequently asked questions

How much does home charging earn per kWh? On average an indicative price of around €0.13 net per kWh, after service fees and market-dependent.

How much per year? At about 3,000 kWh of home charging you are around €390 per year (indicative). More home charging means more revenue.

Is this guaranteed? No. The ERE price is market-dependent, so we work with indicative prices and a range.
