10-year planning permission to develop a Combined Cycle Gas Turbine (‘CCGT’) and Open Cycle Gas Turbine (‘OCGT’) Thermal Power Plant, Electricity Grid Connection including 2 no. substations, and associated buildings, plant, site works, services and ancillary development on land within the townlands of Knockdrin, Derrygreenagh, Derryarkin, Derryiron, Ballybeg, Coolcor, Barrysbrook, Clonin, Togher and Coole, Co. Offaly.
The Proposed Development will encompass a Power Plant Area and an Electricity Grid Connection. The development of the Power Plant Area will include the following:
• Demolition of existing buildings at the Derrygreenagh Works site (Including office building, boiler house, workshops, water tank and storage unit);
• Construction of CCGT power plant (570MW) [Including turbine hall and associated buildings, air cooled condensers (‘ACC’), Heat Recovery
Steam Generator (‘HRSG’), air intake, emissions stack (60m high) with Continuous Emissions Monitoring System (‘CEMS’) and platform];
• Ancillary coolers;
• Fuel gas performance heating room
• Generator transformer and unit auxiliary transformer;
• OCGT power plant (140MW) [Including turbine enclosures, air intakes, fin fan coolers, emissions stack (45m high), electrical rooms, main transformer];
• Secondary fuel storage tanks and unloading area [Including unloading layby, 2 no. fuel storage tanks, fuel pumping and cleaning plant, fuel forwarding building];
• 2 no. water abstraction boreholes;
• Raw water storage tank;
• 2 no. demineralised water storage tanks;
• Water treatment plant;
• Administration building and staff car park;
• Wastewater treatment plant;
• Workshop and stores building;
• Process water treatment plant; Gas Above Ground Installation (‘AGI’)
compound [Including regulator building, instrumentation kiosks, palisade fencing];
• Gas receiving facility [Including gas compressor building, fin fan coolers, pressure reducing station];
• Drainage infrastructure [Including surface water attenuation tank, surface water discharge pipeline (Discharging to the Mongagh River),
treated process and wastewater discharge pipeline (Discharging to the Yellow River)];
• A new site access from the R400 road;
• All internal access roads;
• Security fencing and gates;
• Landscaping
• Site works and services
• All ancillary infrastructure and plant [Including firefighting systems, fire water pumphouse, raw water pumphouse, emergency diesel generator, propane stores, chemical storage tanks and pumphouse, lube oil storage building, silencers, vents, drains, safety valves, lighting, and pipe gantries];
• A permanent Peat and Spoil Deposition Area (‘PDA’) of approx. 225,000 sq. m. will be located to the south-east of the Power Plant Area.
The development of the Electricity Grid Connection will include the following:
• A 220kV substation located to the west of the Power Plant Area and R400 road [Hybrid gas insulated switchgear (‘GIS’)/air insulated
switchgear (‘AIS’) substation design including switchgear building; control room building; transformer bays; 2. no. lattice gantries (c. 20m high) to support overhead line connection; telecommunications mast (c. 36m high); security fencing; landscaping, new access on to R400 road];
• 220kV overhead line running for c. 5km to the south of the 220kV substation, facilitated by double circuit suspension pylon towers (13 no.; c. 44m high) and strain pylon towers (6 no.; c. 38m high);
• 220kV line-cable interface compound [Including interface tower gantry (c. 20m high); cable sealing ends; security fencing];
• 220kV underground cable connection running for c. 3.4km to the south [With paved and gated service road and 12 no. joint bays to facilitate
construction and servicing];
• A 400kV GIS substation located adjacent to the existing Oldstreet-Woodland 400kV overhead line [Including a 400kV GIS building; 220kV GIS
building; transformer compound; 2 no. lattice gantries (c. 28m high) to support overhead line connection to 2 no. new loop-in strain towers (c.
32.5m high) on the Oldstreet-Woodland 400kV line; telecommunications mast (c. 36m high); security fencing; landscaping, access off L1010
road];
• 2 no. permanent Peat Deposition Areas will be provided as part of the Electricity Grid Connection – one to the north of the 400kV substation (c. 75,300 sq. m) and one to the south-west of the 220kV substation (c. 50,200 sq. m.);
• Tree Replanting Areas (c. 17.5 ha.) are proposed within the planning boundary to compensate for all tree felling requirements associated with the Proposed Development.
The application relates to development for the purposes of an activity requiring a license from the Environmental Protection Agency under the
Environmental Protection Agency Act 1992, as amended. It also relates to a COMAH establishment and therefore falls under the requirements of the Chemicals Act (Control of Major Accident Hazards Involving Dangerous Substances) Regulations, 2015. An Environmental Impact Assessment Report (‘EIAR’) and Natura Impact Statement (‘NIS’) will be submitted with the application.
