DSO - France
Publication info
| Publication status | Aiming for publication in the first semester of 2026 |
| Access type | Open |
| Geographical Coverage | All regions of France served by Enedis (representing 95% of the territory) |
| Spatial granularity | The map is intended for producers seeking connection to the distribution network (not for storage or consumption purpose). RTE contributes to the project by integrating congestion constraints from the transmission network that may impact distribution‑level hosting capacity |
| Voltage Level Coverage | Hosting capacity is displayed by substation (20 kV). |
| Time Horizon (e.g. Y+1, Y+3 / 202x / snapshot) | Hosting capacity is provided for Y+3 with integration of the queue. |
| Data Format (Table, Map, etc.) | Map |
| Grid user types covered | All renewable producers, mainly solar and wind |
| Displayed Capacity Type (e.g. available/requested/reserved/connected etc.) | For each substation, the map indicates whether the area is congested (red) or not (grey) for at least 5 years. |
| API Availability | Not Applicable |
| Grid hosting capacity downloadable & format | No |
| Update Frequency | Estimation: Three times a year |
| Available language | National language(s) only |
Hosting capacity assessment
| Capacity type considered for available hosting capacity information (e.g., Firm and/or Flexible) | Firm |
| Description of what firm capacity means | Producers cannot connect in areas identified as congested. |
| Description of the aspects/methodology that leads to firm capacity results | The map displays congested areas for new producers whishing to connect to the distribution network, while integrating both DSO and TSO congestion constraints, including projects already in the connection queue. |
| Description of what flexible capacity means (if applicable) | Flexible connections can be proposed in some cases, but no connection (neither firm nor flexible) is possible in congested areas (red). |
| Description for the criteria and methodologies used that lead to the published information | The map shows four colours: - Red: Congested area = The area will be congested for at least 5 years - Grey: not congested area or partially congested = hosting capacity available for DSO network and must be verified using Enedis website « Cartographie des capacité ». To be confirmed by RTE (French TSO). The “Cartographie des Capacités” website, available exclusively through Enedis’ dedicated portals for companies and public authorities, enables users to assess the hosting capacity of medium- and low-voltage distribution networks and to identify potential network constraints for a given location and for consumption or generation projects below 2 MW. |
| Main assumptions/disclaimers behind calculations | This map provides an indicative overview at substation level to support early‑stage project development. It does not replace the official connection request process, as detailed studies are required to confirm actual connection capacity |
Additional information for connection request and hosting capacity information
| Connection request procedure | https://www.enedis.fr/je-raccorde-une-installation-de-production-delectricite |
| Available options for the investors if the map shows “no capacity available” in their interested area | Investors can either wait for the works to bring additional capacity or change their project location. In some cases, they may benefit from an alternative connection offer with non-compensated curtailment. |
| Connection request rules/principles | First come, first served. Once a customer submits a complete application for connection requests, the requested capacity is reserved until they exit the queue, either upon commissioning or upon declining the connection offer. |
| Information published for volumes of connection requests/waiting lines | No. The hosting capacity map integrates the waiting lines, but the volume of connection request is not available. |
