8.5 million ERE traded in total, for €3.8 million gross.

* Gross per kWh: the sale price per ERE converted per kWh charged at home (one kWh yields ± 0.33 ERE), before service fees. Which fee comes off differs per customer and contract; your dashboard uses your own rate. The charging quarter is the quarter in which the traded kWh were charged; payout follows per quarter once the sale is settled. The transfer is the quarter in which the ERE's are delivered to the buyer • only compare a price with a sale that transfers in the same quarter. New sales appear here automatically.

The first sale made the news through an ANP press release: the first 2 million emission units, of which nearly € 1 million goes to Dutch EV drivers.

One rule: only prices from a sales ledger

A published rate does not say what a customer receives. A sale does: date, volume, price per ERE and broker. So calculate only with prices from a sales ledger. State per provider what comes off the proceeds before the service fee, and when the money lands in the account. Our ledger is above, and as JSON and CSV at joulo.nl/api/ere-verkopen, under CC BY 4.0.

How we get from kWh to euros

  1. 01

    From kWh to ERE

    Every kWh charged at home is worth about 0.33 ERE: the renewable share of the Dutch grid (50.5%) times the CO₂ factor of 0.6588 kg per kWh.

  2. 02

    Traded at the market price

    Joulo sells the registered ERE's through brokers to parties with a reduction obligation. The price depends on the market: averaged over our 8 sales it is €0.12 net per kWh at the standard fee.

  3. 03

    Your share

    Your service fee comes off the gross proceeds; that fee differs per situation (consumer, business, through an energy partner, or with a discount). We pay out the rest quarterly, once the sale has settled • your dashboard always uses your own rate.

  4. 04

    Earlier transfer, quarterly payout

    The standard transfer of 2026 ERE's takes place in the first quarter of 2027. We transfer one to two quarters earlier, so we can pay you out quarterly. In our sales so far that cost €0.005 per ERE per quarter. That amount is stated on the broker's confirmation and is already in the price you see here; you find it per sale under Details in the ledger. So only compare a price with a sale that transfers in the same quarter: €0.48 transferred in Q1 2027 is worth less than €0.48 transferred in Q4 2026.

How we sell

We sell your ERE's through brokers, at the market price of the day, in parts across the year.

At the day price

We sell a part at the price the market pays that day. We record every sale with date, broker and price.

In parts across the year

8 sales since July 2026. So no single day sets what your ERE's earn.

  • The upside is yours

    If we sell higher, you receive more. We keep only our service fee. We pay the broker fee ourselves.

  • You see every price

    Every sale is in the ledger above, with date, broker and price. What you receive, we calculate from that price.

  • You are not locked in, and neither are we

    You can cancel your contract with us every year. That is why we do not lock ourselves to one buyer for years either.

And if the market falls?

Then we sell lower, and you receive less too. That comes with an honest price: we cannot give you the upside and hide the downside.

But your ERE's do not all go out at once. We sell in parts, and most customers have ERE's in several sales. So one low sale does not set your whole payout.

Your dashboard shows exactly which of your ERE's we traded and at what price. What is not traded yet is shown separately, with a forecast at the current market rate.

What your ERE's earn, you see per sale

We do not name a fixed amount per kWh up front. We sell at the market price, charge our service fee and publish the result. So you see exactly what your ERE's earned.

The ERE price moves with the market and can therefore also fall. That is why we don't promise amounts up front: here you see what each sale actually returned, and the calculator always uses three scenarios (low, mid and high).
