As the owner of a high-voltage cabin or a natural gas access point with a capacity ≥ 250 m³/h, you are legally obliged to sign a connection agreement with Sibelga.

This agreement specifies the rights and obligations relating to your connection, as set out in the Technical Regulations. It also formalises the specific technical conditions and arrangements (no financial impact). 

For any commissioning of a high voltage cabin of a natural gas access point with a capacity ≥ 250 m³/h, you must be in possession of:

  • an active supply contract with your energy supplier. 
  • a signed connection agreement
  • a statement of compliance for the installation
