Planning and delivery status
Current undated PAR11 service listing and a May 2026 supplier account support campus operation following Mercury’s October 2025 handover. The 76 MW design total does not establish live or available capacity in every building.
Stage source: Publication date unstatedProject intelligence. This record does not establish that the land or facility is available to acquire.
POWER STUDY
Power
What the power evidence establishes
The site-specific connection scope has not been established for this record.
No same-scope, dated import-MVA rung has document-seen or better verification. Nearby infrastructure, IT MW and marketing claims cannot upgrade the class.
The class describes published documentary evidence at its stated date. It does not prove current contractual rights, transferability or an energisation date.
Class describes evidence maturity. Public records do not prove current contractual rights, transferable capacity or an energisation date. This record has not received a complete power study review.
Read the rules and verification levelsCapacity ladder and evidence
Each rung is a separate MVA claim for its stated site or phase. A missing rung is unknown.
Applied
Not established from the public records reviewed.
What applied mva is evidenced for the assessed site scope?Offered
Not established from the public records reviewed.
What offered mva is evidenced for the assessed site scope?Accepted / contracted
Not established from the public records reviewed.
What accepted or contracted mva is evidenced for the assessed site scope?Energised
Not established from the public records reviewed.
What energised mva is evidenced for the assessed site scope?Conflicts and scope comparisons
No conflicting pair is recorded. This does not establish that all public statements have been reconciled.
France grid context
Network publications frame the claim. They do not allocate capacity to this site.
No country context entries have been linked to this site. Applicable policy, capacity information and reinforcement dependencies need review.
Derived energisation window
The observed inputs do not establish a bounded delivery range. Open bounds stay unknown.
Rule
Use only a same-scope, dated, document-verified capacity rung and an applicable duration to energisation published by the observed site operator. The named process operator and a named source publisher must match that operator. Earliest year is the maximum of stage date plus minimum duration and each evidenced readiness constraint. Latest year is the maximum of stage date plus maximum duration and each published upper constraint only when every required input is bounded. An offer-processing duration is excluded. A missing required input leaves the affected bound unknown; no padding or contractual delivery promise is inferred.
No observed inputs establish this result.
Dependencies driving the range
- Connection-dependent reinforcement scope and completion dates: unknown.
- Grid-works planning status and programme: unknown.
- Applicable connection-policy conditions and programme: unknown.
What the earliest case requires
- Connection-dependent reinforcement scope and completion dates introduces no later constraint than the earliest case; this remains unverified.
- Grid-works planning status and programme introduces no later constraint than the earliest case; this remains unverified.
- Applicable connection-policy conditions and programme introduces no later constraint than the earliest case; this remains unverified.
Missing inputs leave the range open
- A dated, document-verified import-MVA rung for the assessed scope.
- An applicable duration from the evidenced stage to energisation, published by and matched to the observed site operator, rather than an offer-processing target.
- Connection-dependent reinforcement scope and completion dates
- Grid-works planning status and programme
- Applicable connection-policy conditions and programme
Indicative HV and connection capex
Unknown
Rule and scope
Sum each published complete scope quantity multiplied by the matching published benchmark minimum and maximum. Configuration, voltage, route type, unit, country applicability, currency and explicit price base year must match. No assumed route length, transformer count, exchange rate, inflation, fee uplift or partial index is inserted. The result is an indicative benchmark band, not an operator quotation or contractual connection charge.
No observed inputs establish this result.
Scope questions
- Obtain a published complete connection scope with voltage, configuration and measured quantities.
- Establish that every necessary connection-work component is included in the published scope.
- Identify network and customer works, upstream reinforcement, land and wayleaves, taxes, fees, securities, contingency and the price base.

Request a Reality CheckEarlier capacity notes and source context
Combined PAR8, PAR9, PAR10 and PAR11 campus design IT capacity; no available-capacity or MVA inference.
Published claimProject source recordThe historic design separated western-building Enedis connections from the RTE-fed eastern pair. This establishes a proposed network arrangement, not present contracted import.
IT load, facility demand, import capacity and equipment ratings retain their stated scope. A published figure does not establish spare or transferable supply.
Planning & utilities
7 of 10 categories contain evidence. Each status applies to its specific claim.
Planning & decisions
Partial evidenceDRIEAT identifies the 24 September 2021 authorisation for INTERXION France’s four buildings PAR8–PAR11 at 2 avenue Marcel Cachin, AIOT 0006523747. Géorisques records authorised operation and a later inspection on 21 May 2026. This campus is distinct from PAR7 at rue du Rateau, AIOT 0006514850.
Sources & next check
Land-use zoning
Partial evidenceThe 2018 impact study locates the scheme in zone UE and identifies infrastructure servitudes. It predates the current planning framework.
Sources & next check
Grid & import rights
Partial evidenceThe historic design separated western-building Enedis connections from the RTE-fed eastern pair. This establishes a proposed network arrangement, not present contracted import.
Sources & next check
Land, footprint & access
Partial evidenceMercury identifies about 39,000 m² of technical space and a 7,500 m² public park. These are functional areas, not a verified developable land boundary.
Sources & next check
Flood, ground & environment
Partial evidenceThe 2018 study records contamination/remediation risks. The May 2025 DRIEAT inspection proposed corrective action on generator records, acoustic evidence, electrical isolation and emergency provisions. These were inspection findings, not proof of ongoing breach or a new refusal; closure remains unchecked.
Sources & next check
Water, cooling & heat
Partial evidenceThe 2025 inspection quotes the consent’s public-potable-water supply and monthly metering duties; it requested improved records of dry and adiabatic cooling operating hours. Contractor descriptions of hybrid/free cooling do not establish compliance or current water headroom.
Sources & next check
Programme & delivery
Partial evidenceDRIEAT found PAR8–PAR10 operating in May 2025 and records PAR10 delivery on 19 December 2024; its then-target for all four was 2027. Mercury’s 2020–2025 campus period and the 2026 PAR10/PAR11 fire-protection reference describe other milestones.
Sources & next check
Not assessed
Evidence still needed
- Fibre & dark fibre
No verified site entry, dark-fibre offer or physically diverse route assessment is recorded. Regional coverage alone is insufficient.
- Ownership & development control
Legal title, land-owning entity, development-control route and restrictions need verification. A named developer does not establish availability.
- Demand & location fit
Customer geography, latency, cloud or exchange nodes and a supported use case need project-specific evidence; national growth alone is insufficient.
