It includes PV support structures, string inverters, transformer stations, underground electrical cabling, internal tracks and hardstanding.

Long-term energy infrastructure

The scheme seeks a 10-year construction period and identifies a 40-year operational life. Associated infrastructure includes perimeter fencing and gates, CCTV, drainage, a temporary construction compound, landscaping and habitat enhancement.

Established site proposal

The same Derrygrogan Little and Derrygrogan Big site has been the subject of earlier permission submissions for the same approximately 28.1-hectare Solar PV scheme, including the same core electrical, access, drainage and environmental measures.

Environmental assessment
