Grid conformity in Belgium: Fluvius, Sibelga and ORES
From 100 kVA of storage, the Belgian grid operator requires telecontrol. Voltmasters connects directly to the grid operator's RTU and guides certification end to end. In Flanders we are fully Fluvius-compliant, with the most customers and the deepest expertise. We also support Sibelga in Brussels and ORES in Wallonia.
The three Belgian grid operators
Belgium has one grid operator per region, each with its own telecontrol requirements, application procedure and validation. Our deepest expertise is with Fluvius in Flanders, where we work fully compliant.
Fluvius
FlandersThe grid operator for all of Flanders. This is where we have the most customers and the deepest expertise: from Netflex application and RTU link to validation and certification, often completed in a single session.
Sibelga
BrusselsThe grid operator for the Brussels-Capital Region. We handle the telecontrol link and the coordination with Sibelga for your connection.
ORES
WalloniaThe largest grid operator in Wallonia. We connect the installation to the telecontrol requirements and guide compliance.
Fluvius integration in Flanders, end to end
For our Flemish customers we handle the full Fluvius link: from application and wiring to validation and certification. That way your project goes live in line with the Netflex requirements.
- Netflex interface over the IEC 60870-5-104 protocol: Fluvius RTU ↔ Voltmaster Controller ↔ assets
- Voltmasters IO extension on site for the DSO signals, including a hardware emergency stop
- Validation against real measurements: active and reactive power, Q mode, emergency stop and feedback per category
- Guided DSO certification with real-time diagnostics, often completed in a single session
- 100% Fluvius-compliant at a minimal surcharge: full onboarding included, from connection and configuration to validation and coordination with Fluvius
The control loop, visualised
The grid operator commands, the controller regulates, the site reports back
The grid operator sets a power limit over the IEC 60870-5-104 protocol. The Voltmaster Controller ramps the assets down in a controlled way and feeds the measurements back in real time, with an independent hardware emergency stop that the controller executes through its IO extension as a safety net.
Direct measurement via the Fluvius A1 port
For high-consumption connections (>100 kVA) in Flanders, the EMS reads the industrial Fluvius meter directly via the A1 port (RJ12/RJ45), real-time quarter-hour values for active and reactive power. The residential digital meter (P1) is supported as well.
Real-time quarter-hour values
Continuous tracking of the quarter-hour averages on which the capacity tariff is calculated.
No extra sub-meters
Official meter data comes in directly, less hardware, fewer error sources.
Manage the capacity tariff
Peak shaving steers on exactly the same measurement as the grid operator's invoice.
No billing discrepancies
The data in the platform matches the supplier's settlement one to one.
