ERE eligibility
Does the OpenEVSE WiFi have a MID meter for ERE registration?
No, the OpenEVSE WiFi does not have a MID-certified meter by default. For ERE registration, Joulo arranges an upgrade to a MID-certified charger, or you request a Secondary Allocation Point (SAP) with your grid operator with its own energy meter.

How do I connect my OpenEVSE with Joulo?
You add your OpenEVSE to your Joulo account for session tracking. For ERE registration, a MID upgrade or a Secondary Allocation Point with your grid operator is required.
What can I earn with my OpenEVSE?
Our customer average is 4,100 kWh charged at home per year. That earns you about €530 per year in ERE's, roughly €130 per quarter. This is the mid scenario of €0.13 net per kWh, after the 20% service fee. Referrals lower your fee to 10%.
What does it cost?
A 20% service fee on the revenue. No subscription and no connection fee. The contract is cancellable yearly and we pay out every quarter.
Do I need a green energy contract?
No, and your supplier does not matter. ERE units cover the renewable share of the Dutch grid mix. For 2026 that share is 50.5%.
Do charging sessions from before I signed up count?
Yes, as long as the MID meter measured them. Sessions from 1 January 2026 count, and 2026 sessions can be registered up to and including 25 February 2027. Sessions from before the MID meter never count.
When does the money reach my account?
Every quarter, on the account from your registration. Your dashboard shows per charging session where the amount comes from.
