Typical situation no. 3
A regional operator wants to build a 12 MW data center near Lyon. Public maps show available capacity at the nearest primary substation. Yet the Enedis pre-study mentions reinforcement and a 30-month lead time.
WHAT IS BLOCKING
- The capacity shown for a primary substation does not account for feeders already in use or for pending requests.
- 12 MW is at the upper limit of what is usually connected at MV (HTA): above that, projects often move to HV (HTB).
- The cost of a dedicated feeder and possibly a half busbar section can change the project's economics.
WHAT WE DO
- Review of the Enedis pre-study and identification of what triggers the reinforcement.
- Comparison of three options: MV (HTA) on a dedicated feeder, MV (HTA) in two tranches, HV (HTB) with a customer substation.
- Cost and lead-time estimates for each option, with their risks.
- Preparation of the technical discussion with Enedis.
WHAT YOU GET
- A comparison table of connection options with estimated costs and lead times.
- A reasoned recommendation.
- The list of questions to put to Enedis.
Typical format: Desk review and discussion with Enedis, about two weeks. Every assignment is scoped in writing before it starts.
