What the power evidence establishes
The site-specific connection scope has not been established for this record.
Power classDNo qualifying rung
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.

Netherlands 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.

04
Derived energisation window
Earliest plausible yearUnknown
Latest plausible yearUnknown
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
05
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.

Planning & utilities
6 of 10 categories contain evidence. Each status applies to its specific claim.
Planning & decisions
Partial evidenceMunicipal publication gmb-2024-378964 records grant of the southeast expansion’s spatial permit under case Z2024-00000697 at Lakenblekerstraat 13. This is a phase-specific consent, not evidence that all later expansion phases are approved.
Sources & next check
Fibre & dark fibre
Partial evidenceCogent lists NorthC Aalsmeer at Lakenblekerstraat 13 as an on-net carrier-neutral data-centre location. That supports a specific carrier presence; dark fibre, free pairs and independent routes remain unverified.
Sources & next check
Ownership & development control
Partial evidenceRijnland names NorthC DataCenters B.V. as permit holder for the Aalsmeer extension. The document identifies development responsibility but does not establish registered land title or transferable development control.
Sources & next check
Flood, ground & environment
Partial evidenceRijnland consent 2024-015515 requires 122 m³ compensatory water storage for added hardstanding, installed before or alongside that hardstanding, with controlled discharge and ongoing maintenance. This is drainage evidence, not full flood or contamination clearance.
Sources & next check
Water, cooling & heat
Partial evidenceEnergy Hub Aalsmeer describes a water ring delivering recovered data-centre heat to local partners and returning cooled water to NorthC. The project page dates the start of exchange to September 2019. Current contracted volumes and performance are not published.

Programme & delivery
Partial evidenceFirst expansion added 2.4 MW IT in late 2025; a second 2.4 MW phase targets infrastructure connection in Q1 2027.

Evidence still needed
- Land-use zoning
The site boundary has not been matched to the current adopted zoning map and data-centre use policy.
- Grid & import rights
Site-specific import rights, available MVA, connection milestones and any transfer restrictions remain unverified.
- Land, footprint & access
Gross and net developable area, boundaries, access rights, easements, setbacks and expansion space need site-specific evidence.
- Demand & location fit
Customer geography, latency, cloud or exchange nodes and a supported use case need project-specific evidence; national growth alone is insufficient.
