Why this application matters
Grid connection
The proposal is for a 31.34-metre 110kV overhead electricity line linking a Battery Energy Storage System (BESS) with the Thornsberry 110kV substation at Derrynagall or Ballydaly, Tullamore.
Established BESS site
The location has a record of BESS and grid-services proposals, including a 3.5-hectare facility with up to 80 containerised battery blocks, electrical substation and control buildings, inverter/transformer modules, cabling, access works and security infrastructure.
Related site design
Related submissions describe a revised BESS layout on an approximately 4.9-hectare site, with 28 to 112 battery containers, a high-voltage electrical yard, switchgear building, ancillary buildings and grid equipment. The overhead line provides the stated connection between this type of storage infrastructure and the Thornsberry substation.
