Overview

DTCP-backed development acquired through Atlantic Hub in 2024. GreenScale reports 119,000 m² acquired near Foyle Port; the registered land-owning SPV remains unverified. RRY11 is the initial phase, included here rather than counted again.

Planning and delivery status

Developer confirms early construction, including clearance and roads, with TSL. This stage describes enabling works; the current 2028 ready-for-service date remains a target.

POWER STUDY

Power

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.

03

United Kingdom 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.

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.

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

  • 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.
Country reference bands and sources

No eligible published capex reference has been recorded. Country bands remain unknown.

Earlier capacity notes and source context
100 MW importProject capacity

Campus grid connections reported as secured by GreenScale; not commissioned IT load. Proposed expansion to 300+ MW is separate.

Published claimProject source record
Import rights and connection evidence

Developer reports 100 MW grid connections secured; underlying utility agreement and energisation not reviewed. Future 300 MW expansion excluded.

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

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

Planning & decisions

Partial evidence

Released DAERA records link the first-building reserved-matters case LA11/2023/1729/RM to Condition 2 discharge application LA11/2025/0037/DC. After earlier objections and revisions, Water Management Unit was content to discharge the final CEMP condition on 13 June 2025. This consultee position does not itself establish the council discharge order or discharge of every condition.

Sources & next check
Evidence reviewed 28 Sept 2026

Next check

Retrieve the council decision and complete condition tracker; retain the dated consultation sequence rather than treating the earlier objection as current.

Grid & import rights

Partial evidence

Developer reports 100 MW grid connections secured; underlying utility agreement and energisation not reviewed. Future 300 MW expansion excluded.

Sources & next check
Evidence reviewed 26 Sept 2026

Next check

Review connection agreement, contracted milestones and energisation evidence.

Flood, ground & environment

Partial evidence

The council’s connection-route response identifies nearby historic lime/tar remediation under LA11/2021/0909/F and LA11/2016/0229/F. Its study area is a proposed cable/BESS corridor near Coolkeeragh, not proof of contamination across the data-centre footprint. Construction pollution controls also underwent the 2025 CEMP review.

Sources & next check
Evidence reviewed 28 Sept 2026

Next check

Overlay the actual cable route and campus red lines with remediation boundaries; retrieve completion validation and the approved CEMP.

Water, cooling & heat

Partial evidence

DAERA’s released consultation raised Culmore 2 wastewater-treatment/sewer capacity and required NI Water agreement or a separate discharge consent where appropriate. The file identifies wastewater dependencies; it does not verify a present cooling-water allocation.

Sources & next check
Evidence reviewed 28 Sept 2026

Next check

Locate NI Water acceptance and current construction/operational discharge consents, then distinguish sanitary, stormwater and process-cooling flows.

Programme & delivery

Partial evidence

GreenScale’s 7 August 2025 update confirms TSL-linked early works including clearance and roads. Existing construction stage/date retained; main building completion remains future.

Evidence still needed
  • Land-use zoning

    The site boundary has not been matched to the current adopted zoning map and data-centre use policy.

  • 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.

  • 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.
