# Supported grid operators

DSO RTU is **operator-specific**. Each grid operator defines its own:

* **Protocol**: how the RTU and the EMS communicate.
* **Data model**: which limits, modes, commands and measurements are exchanged, and how they are encoded.
* **Certification process**: the certification (conformity test) the installation must pass.

The Voltmasters EMS hides these differences behind a single **DSO RTU provider** setting per project. The asset-side logic, how PV, batteries, EV charging and loads are curtailed, is **the same regardless of operator**. Only the protocol mapping and the certification flow differ.

### Selecting the provider

The DSO RTU provider is configured per project under **Project settings → Telecontrol**. When a provider is selected, the EMS activates the matching DSO RTU interface and starts accepting the grid operator's RTU connection.

### Currently supported

| Grid operator                                     | Region        | Status    |
| ------------------------------------------------- | ------------- | --------- |
| [**Fluvius**](/dso-rtu/grid-operators/fluvius.md) | Flanders (BE) | Supported |

### Roadmap

Voltmasters is extending DSO RTU to other grid operators. Because the EMS is **provider-pluggable**, adding an operator means adding its protocol mapping and certification flow, without changing how your installation is controlled or how it is monitored on the platform.

| Grid operator   | Region        | Status     |
| --------------- | ------------- | ---------- |
| ORES            | Wallonia (BE) | Planned    |
| Sibelga         | Brussels (BE) | Planned    |
| Other operators | —             | On request |

{% hint style="info" icon="lightbulb" %}
Need DSO RTU for a grid operator that is not listed yet? Contact Voltmasters. The interface is designed to be extended, and the commissioning and [certification](/dso-rtu/commissioning-and-certification.md) support works the same way for every operator.
