As a Grid User, you are the owner of your metering data. You may want to give access to this data to external companies (such as energy service providers, consultants, software platforms, or even your Balance Responsible Party) to help you with monitoring, reporting, optimization, or analysis of your electricity usage or production.
With the new Metering Data Sharing service, you can now manage such data sharing permissions directly through EPIC, in a secure, transparent and fully traceable way.
This article explains why the service exists, what it allows you to do, and how you can use it to approve or revoke third-party access.
Why would I share my metering data?
Many companies offer services that rely on accurate and timely metering data. These include (but are not limited to):
- Energy monitoring & analytics platforms
- ISO50001 & ESG reporting tools
- Forecasting, optimization & flexibility services
- PV, EV, storage or production asset management
- Software vendors providing dashboards or alarms
- Your BRP validating production/consumption behind your access point
These partners act as Energy Service Providers (ESPs) or third-party data recipients.
By sharing your metering data, you enable them to offer you better insights, more efficient operations, and improved energy management.
What is the Metering Data Sharing service?
Metering Data Sharing is a new digital service in EPIC portal that allows grid users to:
- Review and approve requests from third-party companies who want access to your metering data
- Control exactly which data they are allowed to access (points, period, type of data)
- Revoke access at any time
- Track all permissions in one place
- Ensure that all data sharing is explicit, secure, purpose bound, and traceable, in line with EU Regulation 2023/1162
Importantly, this service replaces the previous manual process (Annex 8 of the Commercial Metering Contract), which was slow and difficult to maintain. The new process is digital, faster, more transparent, and gives GUs full control over who is asking access, what data they want and why they need it.

How does the sharing process work?
There are three steps:
1. The third-party submits a request (via API)
A third-party company sends you a permission request through Elia’s API platform (TraXes).
Their request includes:
- Your EAN(s) - previously communicated or publicly accessible Access Point(s)
- The type of metering data they want to access (measured properties)
- Additional ones can be added by the GU in EPIC beyond those explicitly specified by the data recipient in their request
- The period during which they want access (mandate duration)
- Not editable by GU; in case of disagreement, request is to be rejected (a comment can be provided in EPIC which the 3rd party can see) and a new request with the agreed duration is to be submitted
- Not specifying an end date, request is submitted for an undetermined mandate duration
- The data period which they want access to (including historical)
- By specifying a past start date, historical metering data can be requested
- Not specifying a data period, the mandate period is taken by default
- By specifying a future date, continuous data provisioning can be ensured
- A description of the purpose for which they wish to access your data
- Their company name and contact details are automatically retrieved based on their Elia account[AD3] [V(4]
To see the service in the EPIC left navigation, toggle on the “Metering Data Sharing” user access rights from “Accounts Management” or contact your company administrator.
2. You review the request in EPIC
In EPIC, users with the role “Metering Data Sharing” can:
- View all incoming requests
- See exactly which EANs and which data types are requested
- Add more measured properties for the requested EAN(s)
- Check the request and data period
- Check the requester details
- Approve or reject the request with a single click
Click on a request to view its details and you can approve or reject with one click:
3. After approval, the third-party can access the data
Once you approve the request:
- A permission record is created
- Access is activated automatically
- The third‑party can retrieve your metering data via the existing Metering Data API, under the ESP access profile
At all times, you can revoke their access directly from EPIC.
Access stops immediately after revocation.
Which metering data can I share?
You can approve access to metering data related to:
- Your Access Points
- Your Connection Points
- Your Technical Units (production or consumption)
- Any underlying Elia metered delivery points available in your portfolio
You also control:
- The period (e.g., past year, specific months, ongoing access)
- The measured properties (consumption, production, compensated / non‑compensated, etc.)
This ensures that only the data you choose is accessible.
Why is this process necessary?
Because you are the owner of your metering data, Elia must ensure that data is only shared:
- With your explicit consent
- For a clearly defined purpose
- In a secure and traceable way
Regulation (EU) 2023/1162 requires that:
- Data sharing is auditable
- Data holders maintain access logs
- Customers can easily give, review, and withdraw access
This new service ensures that both you and Elia meet these obligations.
This new service helps ensure that you and Elia can demonstrate compliance with applicable regulatory obligations by relying on structured, auditable workflows.
It replaces informal or less transparent practices that are more difficult to monitor and audit at scale, such as:
- Email-based approvals
- Directly adding third-party users to your EPIC organisation without a standardised, auditable mandate management process
- Manual contract annexes (slow, error‑prone)
Do I have to share my metering data?
In general, you decide which data you share. However, where required by law, Elia must transmit metering data to recognised authorities (BRUGEL, CWaPE or VREG) for regulatory purposes such as the issuance of Guarantees of Origin. This data sharing is strictly limited to what is legally necessary.
Can multiple third parties access my data?
Yes, if you approve each request separately.
Does this cost anything?
Grid Users can access their own metering data and authorise its sharing free of charge.
During the transition from the current manual process (Annex 8 signing and eVMS publishing) to a fully digital model— third parties submit requests for digital mandates and consume the data via traXes API integrations while Grid Users approve requests in EPIC—Elia provides a migration grace period. During this period, all existing and new data recipients benefit from free access. The migration is expected to be completed by mid‑2027.
After the migration, Elia may charge third‑party companies an administrative fee for accessing metering data via APIs. For SMEs and NGOs, any fee is strictly limited to administrative costs only, with no commercial margin applied, in line with EU Regulation 2023/1162 and broader EU data‑sharing principles.
