Official description
Verbatim source text
The proposed development consists of the decommissioning of 23 no. turbines and the erection of 17 no. wind turbine...
Verify against official sourceReviewed build intelligence
What the documents propose
Direct application pending
Pending direct REDIII Commission application. The proposal removes 23 existing turbines and erects 17 replacements. Turbine dimensions are ranges and the illustrated 102 MW output assumes a model not yet selected. No granted, procured or installed scope is established.

Seventeen proposed turbines replace twenty-three existing turbines
Proposed in application · Crumhach repowering application PAX21.324561; removed and proposed turbines are separate measures
What the evidence says
The August EIAR proposes removal of 23 existing turbines and erection of 17 new turbines, with tip-height range 176.6–180 m, hub-height range 105–110 m and rotor-diameter range 133.2–150 m. Its 102 MW capacity illustration assumes 6 MW per turbine; the final manufacturer and rating remain to be selected.
Why it may matter — interpretation
Interpretation: distinguishes decommissioning work from the replacement turbine package and avoids treating 23 as a new-turbine count.
What is not established
The ranges are assessed design flexibility, not one fixed model. The 102 MW illustration is not a confirmed installed capacity or contracted turbine order.

Reinforced foundations assessed with piling as a ground-dependent alternative
Proposed in application · Proposed replacement turbine foundations; assessed maximum envelope
What the evidence says
The EIAR describes reinforced-concrete turbine foundations with a 25 m horizontal and 4 m vertical assessed extent. Piles are an alternative where ground conditions are unsuitable for excavation and replacement. An anchor cage, reinforcing steel and demountable formwork are described; final foundation design depends on the selected turbine.
Why it may matter — interpretation
Interpretation: identifies concrete, reinforcement, piling and formwork coordination without inventing a bill of quantities.
What is not established
No concrete volume, pile count, foundation supplier or installed dimensions are established. The existing foundations have a separate retain-and-cover proposal.

Road upgrades distinguish existing routes from new tracks
Proposed in application · Separate existing-track, public-road and new-track work; Type A detail applies to existing excavated tracks
What the evidence says
The EIAR proposes upgrading 8.2 km of existing access tracks and 4.3 km of public-road corridor, with 5.1 km of new access tracks. The Type A existing-road detail shows up to 150 mm selected granular fill, nominal 5 m running width widened at bends, and geotextile/geogrid only where required by the designer.
Why it may matter — interpretation
Interpretation: identifies road surfacing, aggregate and conditional geosynthetic requirements while preserving the three route categories.
What is not established
The Type A section is an embedded P02 information drawing dated 30 June 2026, republished in the August EIAR. Other track types and prevailing peat/ground conditions govern their own sections; no aggregate tonnage is derived.

110/33 kV transformer and associated high-voltage plant
Proposed in application · Proposed on-site 110 kV substation plant described in the application and grid-method appendix
What the evidence says
The grid methodology lists a proposed 110/33 kV transformer, cable sealing end, surge arrestor, disconnect, current/voltage transformer, house transformer, circuit breaker, harmonic filter and shunt reactor, with EirGrid and IPP control buildings and security infrastructure.
Why it may matter — interpretation
Interpretation: identifies the electrical plant categories that require detailed design and procurement coordination.
What is not established
The methodology is an information-stage outline. No selected brand, equipment rating beyond stated voltage or installation is established. Its off-site cable trench is explicitly outside this wind-farm planning application, although assessed in the EIAR; no off-site trench approval is inferred.
