From kWh to ERE credit
Every kWh you charge at home becomes an ERE via your MID meter: 1 kg CO₂ reduction, recorded at the NEa and tradable. Here's how that conversion works.
Why do polluters pay for ERE credits?
The polluter-pays principle: oil companies buy credits from greeners like you. No subsidy, no taxpayer money.
How much can you earn from home charging?
Realised: €0.129 net per kWh from the sale of 23 July 2026 • typically €360–€750 per year. See the NEa formula.
The ERE market: how are prices determined?
ERE credits trade on a market. The obligation rises from 14.4% to 28.4% by 2030 • which supports demand.
ERE trading: how is your credit sold?
No central exchange. ERE credits are traded bilaterally or via brokers, with transfer in the NEa register. Joulo bundles your kWh and sells in blocks.
ERE for VvE's and shared charging infrastructure
How does ERE work in a VvE garage? Central connection vs. own home connection vs. business location • each situation works differently.
ERE for business: registering commercial charging
Business registration is open to every company: flat 15% fee, entities per legal unit and the 100% route for own generation.
Expensing home charging sessions to your employer
Joulo delivers a monthly or quarterly PDF statement with your sessions and kWh price • ready for employer reimbursement or accounting.
Do you pay tax on your ERE income?
For a private individual with a private car the payout is essentially tax-free. And for company cars the Dutch tax authority has confirmed: the ERE payout is not wages.
Solar panels, net metering and your charger after 2027
Net metering ends on 1 January 2027. Charging on your own solar becomes worth more than feeding back • and every kWh you charge at home earns ERE.
The EAN double check: registered on the right connection
Joulo checks your address against the connection registry and against what your charger reports. So your registration sits on the right EAN.
Charging without internet: your charger just keeps working
Joulo only reads metering data and sends no start or stop commands. If the internet drops, you simply keep charging. Here's how.
Integrations per charger brand
Three ways to get your sessions into Joulo
We support 14+ cloud APIs and 43+ OCPP brands. Pick your route below, then follow the brand-specific guide on /docs.
Cloud API
14 brands
Direct OAuth via your manufacturer account. Joulo reads your sessions and MID meter readings from the cloud • no charger changes.
Back office
Your charger is managed via a CPO platform. Joulo connects once to your back office and fetches sessions automatically. Supported back offices: 50five, Eneco eMobility, Plugchoice, Ecotap EVC-net and Groendus.
OCPP 1.6J
43 brands
Universal charger standard. Change one setting on your charger (the CSMS URL) and Joulo receives sessions via OCPP 1.6J.
CSV (optional)
Have historical session data as an export? Joulo accepts a CSV upload as a supplement to the standard connection. Not a replacement for API, back office or OCPP — automatic source data remains required for audit-proof submission.
Per brand

Tesla
The Tesla Wall Connector Gen 3 in the MID variant is fully supported. Joulo connects through Tesla's official Fleet API (OAuth with your Tesla account). No changes to your charger required. Gen 2 and the non-MID Gen 3 are not eligible: ERE registration requires a built-in MID-certified meter.

Easee
The Easee Charge Max and Charge Pro have a direct cloud connection via your Easee account and a built-in MID-certified meter, so they're directly eligible for ERE. Joulo imports your sessions automatically once linked. Have an older Easee without a built-in MID meter? Check at joulo.nl/check-laadstation • Joulo then arranges a MID upgrade.
Wallbox
Wallbox Pulsar Plus, Pulsar Pro and Commander 2 connect through your existing myWallbox account. Joulo imports your sessions automatically. ERE requirement: a built-in MID-certified meter • not every Wallbox variant has one. Check the model on joulo.nl/check-laadstation.

Zaptec
Zaptec Go 2 and Zaptec Pro use a direct cloud connection via the Zaptec Portal and include a built-in MID-certified meter by default • required for ERE registration. The original Zaptec Go (first generation) does not have a built-in MID meter • for that model Joulo arranges an upgrade to the Go 2, or you request a Secondary Allocation Point (SAP) with your grid operator.

Enphase
The Enphase IQ EV Charger 2 connects through OAuth with your Enlighten account. The IQ EV Charger 2 includes a built-in MID-certified meter • required for ERE. Cloud data depends on Enphase API availability.
Blue Current
Blue Current has a direct API connection. You generate an API key once at my.bluecurrent.nl (under Advanced, desktop only) and paste it into Joulo. After that, Joulo imports your charging sessions automatically, including your history since 1 January 2026. ERE requirement: your charger must have a built-in MID-certified meter, such as the NanoCharge, Nano XL and U:Move. This varies by variant • check at joulo.nl/check-laadstation.
NexBlue
The NexBlue Max range (Edge Max and Delta Max) has a built-in, MID-certified energy meter and is directly eligible for ERE. You log in once with your NexBlue account, after which Joulo reads your charging sessions automatically via the NexBlue Cloud API. For other NexBlue models Joulo checks the MID status automatically.
Ohme
The Ohme Home Pro has a built-in MID-certified meter and is directly eligible for ERE. You connect with your Ohme account (the email and password from the Ohme app), after which Joulo retrieves your charging sessions automatically. The Ohme Home and ePod have no MID meter • for those Joulo arranges an upgrade to the Home Pro, or you request a Secondary Allocation Point (SAP) with your grid operator.

Alfen
Alfen Eve models are MID-certified by default, making them directly eligible for ERE. Depending on how your charger was delivered you can connect via Eneco eMobility (cloud API) or directly via OCPP 1.6J to Joulo. Joulo auto-detects which route fits your charger.
V2C
Using an API key from your V2C account. Note: the standard Trydan without MID isn't eligible for ERE. You need the MID variant (Trydan Pro MID, identifiable by the Pro label and MID sticker). Make sure the product description explicitly mentions 'MID' before buying.
Smappee
Though whether you can register depends on your model. The EV Base and the current EV Wall (article number EVWC-) and EV One (EVOC-) have a built-in MID meter. The EV Wall Home (EVW-), EV Wall Lite (EVWL-) and EV One Home (EVO-) sold until 2025 do not: they meter to IEC 62053-21, which is not MID. Your article number is on the sticker on your charger. The Smappee Cloud connection is live: you request personal API keys from Smappee once, paste them into your Joulo dashboard, and your charging sessions come in automatically every 15 minutes. Connecting via OCPP 1.6J also works.
Volt time
Plugchoice (formerly Volt Time) has a direct OAuth integration. Plugchoice is a platform behind many white-label chargers • the MID requirement applies to the underlying hardware, not the platform. Check your charger model on joulo.nl/check-laadstation.
Shell Recharge (NewMotion)
In two ways: (1) Direct via the 50five / EVC-net cloud API: log in with your 50five account and Joulo imports sessions. (2) Via OCPP forwarding for chargers running on an external back-office. The recommended route depends on how your charger is configured.
CPO platforms
Already have a charge-point operator account? Joulo plugs into your existing platform • your dashboard and remote start/stop keep working.
Plugchoice
Plugchoice (formerly Volt Time) has a direct OAuth integration with Joulo. You log in once with your Plugchoice account, grant Joulo read access to your charging data, and Joulo automatically imports your sessions. The integration runs server-to-server • no changes to your charger required.
Eneco eMobility
Joulo connects directly to your Eneco eMobility account (formerly Eneco Connectric, often used with Alfen Eve home chargers). You log in once with your Eneco portal credentials and Joulo automatically imports your charging sessions and MID meter readings for ERE registration. Your existing Eneco dashboard, payment card and remote start/stop continue to work as before.
Vattenfall InCharge
For Vattenfall InCharge home chargers a dedicated integration page is available with steps specific to Vattenfall. Joulo automatically imports your charging sessions and MID meter readings for ERE registration. Your Vattenfall dashboard and remote start/stop continue to work as before.
