Location

The Summerfield site is in South Australia’s Eastern Hills region, approximately 55km east of Adelaide. The site is located 16 km from the 275 kV Tungkillo switching station and abuts ElectraNet’s 275 kV Tungkillo to Tailem Bend line. Additionally, the SEAGas and APA gas pipelines transition through the site.

The Tungkillo switching station and nearby electricity transmission infrastructure, forms a key part of the 275 kV backbone of the South Australian transmission system and link the Metropolitan, Riverland, Mid-North, Eastern Hills and South East Regions. Tungkillo is a critical node for the energy flowing from Adelaide and/or the Northern regions of South Australia into Victoria, or from Victoria into the Adelaide, via the Heywood Interconnector.
