Operating installation on a 16.5 ha site west of the Google campus; planning SD20A/0121 and EPA licence P1170-01. The 2023 programme retained later B/C phases. Published backup-generator thermal input is not grid demand or IT capacity.

Planning and delivery status
EPA’s 29 May 2023 inspector report explicitly states that the installation is operating, while B/C and full build-out were phased. This label covers the operating campus, not proof that all three buildings are commissioned. Later target dates are not treated as completion evidence.
Stage source: 29 May 2023Project intelligence. This record does not establish that the land or facility is available to acquire.

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.

Ireland 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.

Evidence still needed
- Planning & decisions
A current planning decision, conditions and any appeal or court proceedings still need to be checked.
- 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.
- 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.
- Flood, ground & environment
Flood risk, ground conditions, contamination, ecology, heritage, noise and air-quality constraints have not been fully assessed here.
- Water, cooling & heat
Water availability and discharge, cooling technology, peak demand, heat reuse and utility agreements remain to be verified.
- Demand & location fit
Customer geography, latency, cloud or exchange nodes and a supported use case need project-specific evidence; national growth alone is insufficient.
- Programme & delivery
Permission expiry, commencement, energisation, enabling works, long-lead procurement and phase handovers need a reconciled programme.
