Every ERE sale, in public
Most providers promise an amount per kWh. Joulo publishes what was actually sold: every ERE sale, with its date, volume and realised price. So you can hold us to figures, not to promises.
The sales ledger
| Sale | Charging quarter | Volume | Price per ERE | Gross per kWh* | Paid out | Details |
|---|---|---|---|---|---|---|
| Sale 323 July 2026 | Q1–Q3 2026 | 1.0m ERE | €0.483 | €0.161 | planned | |
| Sale 26 July 2026 | Q2 2026 | 1.0m ERE | €0.481 | €0.16 | planned | |
| Sale 12 July 2026 | Q1 2026 | 1.0m ERE | €0.4775 | €0.159 | planned |
± 3.0m ERE sold in total.
* 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 sold kWh were charged; payout follows per quarter once the sale is settled. New sales appear here automatically.
This ledger is also an open JSON feed: joulo.nl/api/ere-verkopen • free to use with attribution (Joulo) • see the documentation.
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.
Who does the trading?

Harm spent over seven years as a trader at Flow Traders, Europe's largest liquidity provider and market maker in ETFs and futures, active in equity, fixed income, FX and commodities. He holds an MSc in Financial Economics from Erasmus University Rotterdam.
At Joulo he builds the trading strategy behind this ledger: how and when the registered ERE credits are placed in the market through brokers. Every sale runs through him. For questions about a sale or the ERE market • press enquiries too:
How we get from kWh to euros
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.
Sold at the market price
Joulo sells the registered ERE credits through brokers to parties with a reduction obligation. The price depends on the market; as a reference we use € 0.12 to € 0.15 net per kWh.
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). The rest is paid out quarterly • your dashboard always uses your own rate.
Why we don't guarantee an amount
A guaranteed amount per kWh sounds safe, but such a guarantee is an insurance policy you pay for yourself: whoever guarantees a floor prices in that risk and keeps the upside above it. We do it the other way around. We sell at the market price, charge a transparent fee and publish the result.
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).
