The ERE credit: from kWh to tradable unit
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?
Depending on the ERE market price and service provider • typically €390–€850 per year. See the official 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.
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?
The tax authority has no formal position yet. For an ordinary home charger your payout is almost certainly not box 1 income.
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.
Integrations per charger brand
Three ways to get your sessions into Joulo
We support 12+ cloud APIs and 44+ OCPP brands. Pick your route below, then follow the brand-specific guide on /docs.
Cloud API
12 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
44 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
Easee Home and Easee Charge use a direct cloud connection via your Easee account. Joulo imports your sessions automatically once linked. ERE requirement: your charger must have a built-in MID-certified meter. This varies by model • check at joulo.nl/check-laadstation.
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.

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), E-Flux by Road (OCPP forwarding), 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
Smappee EV Base, EV One and EV Wall all include a built-in MID-certified meter. The connection runs via OAuth and is currently being finalized • once Smappee completes approval you'll be able to connect from your dashboard.
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 E-Flux by Road with OCPP forwarding for chargers running on the E-Flux 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.
