Overview

Meta’s first Irish data-centre campus, distinct from neighbouring EngineNode. Named delivery appointments are recorded by package and phase. The developer’s 219 MW renewable-energy figure covers generation projects and is not campus IT load or contracted import; an older architect’s 108 MVA design statement is not treated as a current connection agreement.

CRU/2025236: Large Energy Users Connection Policy decisionCommission for Regulation of Utilities · Source checked

Connection policy for new data centre applications, including matching dispatchable generation or storage, additional renewable electricity and network location assessment. At least 80% of annual demand must be met by additional renewable electricity generated in the Republic of Ireland, with a six-year glide path from energisation. Requirements and transitional scope must be checked against the actual application date and connection position.

A policy requirement is not evidence that a particular site has complied or has connection rights. Onsite or proximate generation is permitted; onsite-only generation is not a universal requirement. Do not retrospectively apply the new application rules to an earlier agreement without checking transitional scope. No fixed publisher update cadence is stated; PowerPlotr proposes a weekly policy check.

Data Centre Connection Offer Process and Policy, Version 3EirGrid · Source checked

Implements CRU/2025236. For new transmission data centres at or above 10 MVA, nominated dispatchable generation or storage must match MIC after applicable de-rating and be delivered before energisation or demand ramp-up. Nominated generation is separately connected and metered and participates in the SEM. The stated offer-processing periods are approximately 7.5 calendar months where nominated generation and renewables already have offers, or up to 18 months where associated generation has newly applied through ECP-GSS.

These are conditional application-to-offer periods, not construction or energisation durations, and are excluded from energisation calculations. A complete application, linked generation status and fees matter. An offer is not an accepted agreement. Earlier applications can remain under CRU/21/124. Publisher updates are event-driven; proposed review is weekly.

Data Centre Technical AssessmentEirGrid · Source checked

Explains application-specific assessment of capacity, voltage, system stability, short-circuit effects and outages. Continuous demand above 50 MW is significant for the Irish 110 kV network and should focus on connection voltages above 110 kV. Dedicated loop-in connections are difficult to integrate and require wider system benefit.

General technical context cannot establish a connection point, headroom or capacity allocation for a particular site. Every proposal still requires operator assessment. Publisher cadence is event-driven; proposed review is monthly and after a related policy decision.

Data Centre Constrained Area OverviewEirGrid · Source checked

Pages 11 to 12 identify high-level potential on the 220 kV network around Galway, Limerick and Cork, subject to individual assessment and policy compliance. The overview considers greater Dublin fully constrained for new data centre development. It advises a prudent mid-2030s assumption for new connections in the identified areas because of work and outage programmes.

Regional opportunity is not site-specific capacity or a contractual right. Mid-2030s is qualitative operator context, not a bounded energisation window or a promised 2035 date. Earlier applications and agreements require their own transitional-policy check. Detailed heat maps are planned through the 2027 Ten Year Transmission Forecast Statement. No recurring publisher cadence is specified; proposed review is monthly.

CRU2026145: Grid Code Modification MPID 345 and Compliance and Derogation FrameworkCommission for Regulation of Utilities · Source checked

Approves fault ride-through, rate of change of frequency and active power recovery requirements for existing and future transmission-connected demand facilities. The technical requirements include remaining connected within the specified voltage profile, withstanding plus or minus 1 Hz/s and recovering 90% of pre-fault active power within 500 milliseconds after fault clearance and voltage recovery to 0.9 per unit. Compliance is assessed at the point of connection.

The associated Grid Code amendment takes effect on 27 October 2026. This is a separate technical requirement from the December 2025 connection policy. Site compliance, an approved derogation and any demand utilisation restriction need direct evidence. Missing public compliance evidence means unverified, not automatically non-compliant. Publisher updates are event-driven; proposed review is weekly.

The CRU directs EirGrid to amend the Grid Code five weeks after the 22 September 2026 decision. EirGrid's Grid Code Modifications register labels this approval effective 27 October 2026. The letter applies the technical requirements to all transmission-connected demand facilities.

The effective date does not itself prove compliance or an energisation entitlement at any site. Review the decision, current Grid Code and any approved derogation together. Publisher cadence is event-driven; proposed review is weekly through implementation.

The checked regulatory publication register lists Transmission Development Plan 2024, the 2024 Ten-Year Transmission Forecast Statement and current adequacy publications. This is the discovery and version-control entry for the earlier published development plan while the 2026 to 2035 draft is under CRU consultation.

A listed project is not evidence that it supplies a particular site, has all consents, or guarantees a delivery date. No reinforcement dependency has been assigned to a pilot merely from geographic proximity. The statutory development-plan cycle is two years; PowerPlotr proposes monthly checks for a new approved version or delivery update.

Search by case reference, location, applicant and infrastructure to match a site with grid planning decisions and conditions. Proposed review is weekly and whenever a relevant case changes.

A grid planning application, pre-application consultation or permission does not establish an executed connection agreement, import capacity, route rights or energisation. Check the actual decision documents and exact development boundary. A target decision date is not the decision. The portal has no guaranteed fixed case-update interval.

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.

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.

Earlier capacity notes and source context

No project-specific capacity figure is published in this record.

Import rights and connection evidence

The applicant describes on-site Bracetown and Clonee 220 kV AIS infrastructure, ESB/EirGrid assets and separate customer transformers. Normal supply is grid electricity; backup generation ratings and the existing architect design rating do not establish a contracted import allowance.

IT load, facility demand, import capacity and equipment ratings retain their stated scope. A published figure does not establish spare or transferable supply.

Not assessed

Land-use zoningFibre & dark fibreDemand & location fitProgramme & delivery
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.

  • 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.
