Data mandate and comparison

Fluvius keeps the official metering data of your grid connection: the quarter-hourly consumption and injection values that your supplier and the grid operator settle on. Voltmasters can retrieve that data for your project, but only after you have explicitly authorised it with a data mandate.

With the data in place, the platform can put the two sources side by side: what Fluvius registered, and what the EMS itself measured on site (the local measurement).

The data mandate

A mandate is an authorisation you grant to Voltmasters, per meter point, to read the metering data of that point. It is confirmed on the Fluvius side with itsme, so it can only be granted by the person who manages the connection.

Requesting a mandate

1. Open the grid connection references

   Go to Configuration → Grid & market → Grid settings and scroll to the grid connection references below the grid settings (see Project settings). The section is shown for Belgian projects only.

2. Add the meter point

   Enter the Meter Point Identifier, the 18-digit EAN of the connection printed on your electricity bill and on your grid connection contract, and choose the Type of data the mandate covers:

   Type	Covers
   Consumption	The energy drawn from the grid.
   Production	The energy injected into the grid.
   Combined	Both directions on the same meter point.

   Click Add to save the meter point.

3. Synchronize with Fluvius

   Start Synchronize with Fluvius. You are taken to Fluvius, where you confirm the mandate with itsme. Use the account that legally manages the connection: a mandate granted by anyone else is refused.

   

4. Check the status

   Once Fluvius has approved the mandate, the meter point shows as Active, together with the moment it was approved, the date it expires, and the moment the data was last synced. From then on the platform retrieves the metering data automatically.

   

The comparison report

The report puts the official Fluvius data next to the local measurement: the same period, as measured by the meter that the EMS controller reads on site.

You find it under Analysis → Reports → Grid operator comparison. The menu entry appears once the project has an active mandate, so a project without an approved mandate does not carry a report that has nothing to show. The entry is named after the grid operator in general, because the same report will cover other operators as they are integrated.

What it shows:

• A date range you choose yourself, and a selection of the meter point (mandate) to compare.
• Consumption and production graphs of both sources over that period, so a deviation is visible as a shape and not only as a number.
• Totals per source and the difference between them.
• Anomaly detection that flags periods where the two sources diverge more than expected, so you do not have to scan the whole range yourself.

What to use it for

• Verify the metering configuration after commissioning: a wrong CT ratio, a reversed measuring direction or a meter on the wrong circuit shows up immediately as a structural deviation.
• Check the settlement figures: verify the quarter-hourly peaks and volumes your operator invoices against what the installation measured.
• Track down unexplained differences: a load or generation source measured on one side and not on the other.
