Distribution Users
In order to activate the internal installation and supply your property with natural gas, in addition to the connection contract with Enaon EDA, you must have signed a gas supply contract with a gas supply company.
Gas supply companies are companies that use the gas distribution network (Distribution Network Users) to supply gas to end consumers. For the provision of services related to the Basic Distribution Activity, natural gas supply companies must have obtained a supply license from the Regulatory Authority for Waste, Energy and Water (RAAEW), registered in the National Natural Gas System (NNGS) Users’ Registry, and signed the relevant Standard Distribution Network Usage Agreement (OGG B’6414/23.10.2026) with Enaon EDA.
