Planning Application for a 110kV substation and a 110kV grid connection route to facilitate Lissinagroagh Wind Farm...
Verify against official sourceReviewed build intelligence
What the documents propose
Direct application pending
Proposed 110 kV substation and connection route. The accompanying EIAR discusses the wider wind farm; that does not make every wind-farm component part of this Commission application. No award or installed specification is established.
3 official documents inspected · Checked 2026-09-05 · Official file index
IPP building roof and wall build-up
Proposed in application · IPP building only, drawing P07
What the evidence says
Drawing P07 specifies 600 × 300 mm blue-black slate, timber roof trusses and battens, breather membrane, 150 mm rock-wool insulation and 12 mm foil-backed plasterboard. It also notes a 200 mm hollowcore ceiling slab for security, galvanised-steel doors, uPVC gutters and plaster-finished cavity masonry.
Why it may matter — interpretation
Interpretation: creates a concrete starting specification for roofing, insulation, precast, masonry and secure doors.
What is not established
The drawing says building/equipment arrangements are indicative and final specifications must follow EirGrid/ESB requirements. No purchase, installed manufacturer or final construction detail is established.

Raised access floor and reinforced slab
Proposed in application · IPP switchgear/control building floor
What the evidence says
The IPP building section shows a raised access floor on a 150 mm reinforced-concrete floor slab, selected insulation, damp-proof course, sand blinding and compacted hardcore.
Why it may matter — interpretation
Interpretation: identifies raised-floor and structural floor coordination needs for the electrical building.
What is not established
Final loads, access-floor manufacturer and construction approval are not stated on this drawing.

10,000 litre foul holding tank with alarm
Proposed in application · Substation staff-welfare wastewater; not a project-wide treatment capacity
What the evidence says
The compound drainage detail specifies a 10,000 litre foul-water holding tank with reinforced-concrete base, walls and roof slab, a high-water alarm connected to the control building, and a D400 cover arrangement.
Why it may matter — interpretation
Interpretation: identifies a tank, concrete, cover and monitoring package.
What is not established
The chapter describes tanker removal rather than on-site wastewater treatment; servicing appointment and final alarm design remain unconfirmed.

Defined underground cable duct arrangement
Proposed in application · Proposed substation-to-Srananagh route in Leitrim and Sligo
What the evidence says
The EIAR describes an approximately 32 km 110 kV connection to Srananagh, including 30.6 km in public-road corridor. The typical trench has three 160 mm HDPE power ducts, two 125 mm communications ducts and one 125 mm earth-continuity-conductor duct; joint bays are described as precast concrete.
Why it may matter — interpretation
Interpretation: identifies ducting, trenching and precast joint-bay work requiring route-specific coordination.
What is not established
Typical dimensions vary at service, bridge and watercourse crossings. The chapter contains an inconsistent written/numerical count for in-road HDD crossings; no crossing count or total material quantity is published.
