A very clear registration process. The technical connection afterwards is a bit tricky, but the issues with my SolarEdge One EV Pro charger were handled very well by Joulo. Works perfectly now, and the app is very clear too.
Easy to get in touch. They respond quickly to questions and then sort it out right away.
I had a fairly complex question involving my chargers and my own energy management system. They genuinely thought along and properly worked out where the problem was, instead of just giving a standard answer. Communication was clear and they actively looked for a solution that fits my situation. That inspires confidence.
Got the link from a colleague, and signing up was clear and went smoothly. The app looks good too!
Handy app, sharp rates, quarterly payouts and fantastic help from Ruben with the installation. And all that for a discount on your electricity price of about € 0.15 per kWh. Nice.
My questions were answered super fast via WhatsApp, on a Sunday. Quickly scheduled a new Tesla charger with MID meter, professionally installed by Ruben. Signing up was a piece of cake with the well-designed app. Flawless so far, highly recommended!
Another provider couldn't connect to my EVBox Elvi MID. After some messaging back and forth with Joulo I was connected: my EVBox now talks to an OCPP proxy, so I can control it with Home Assistant while the charging data flows to Joulo automatically for ERE registration.

Where the money comes from
Fuel suppliers are legally required to reduce the CO₂ emissions of transport. They do this by buying EREs: proof of avoided CO₂. Every kWh you charge at home instead of refuelling delivers that saving • which makes it worth money.
Why through Joulo
The NEa sets requirements for registering parties that an individual household cannot meet. Joulo B.V. is on the official NEa list of registered ERE service providers and bundles your charging sessions with those of thousands of other drivers.
Verify it yourself
