POWER STUDY

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.

Conflicts and scope comparisons

No conflicting pair is recorded. This does not establish that all public statements have been reconciled.

Denmark 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.

Country coverage: prepared sources; site-level research not extended. View all country sources and refresh schedules.

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

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.

Published connection works scope

Unknown

Not established from the public records reviewed.

What complete connection scope is published: bays, stations, voltage, circuits, route lengths and underground or overhead configuration?

Scope completeness

Unknown

Not established from the public records reviewed.

Is the published connection scope complete enough to match every component to a sourced benchmark?

Scope questions

Earlier capacity notes and source context

30 MW facilityProject capacity

Operator-advertised total campus power capacity; first-phase commissioned capacity is not separately disclosed.

Published claimProject source record

Import rights and connection evidence

The municipal technical attachment describes atNorth as a 50 kV Ahøj customer and proposes feeding heat pumps through its internal 20 kV network. This supplies connection-design context, not a verified campus import limit or spare allocation.

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

8 of 10 categories contain evidence. Each status applies to its specific claim.

Planning & decisions

Partial evidence

Alongside the 2 December 2024 backup-power approval, Ballerup issued a no-full-EIA screening decision on 17 March 2026 for Vestforbrænding’s heat-pump project, case 13.03.18-P15-3-26. It lapses if unused within three years; appeal outcome remains unchecked.

Partial evidence

The screened heat-pump project serves the planned Ballerup Boulevard transmission network. Viegand Maagøe’s 26 June 2025 study uses 15 MW thermal recovery for its business case, with 2028 as the expectation; summertime heat offtake is uncertain. No commissioned heat output is established.
