EIA commences for South Australian offshore wind farm [free access]

September 20, 2021

South Australia (SA) Offshore Windfarm Pty Limited, a wholly-owned subsidiary of UK-based Australis Energy Limited, has commenced the environmental impact assessment (EIA) process for the SA offshore wind farm.


Approximately 230 km south of Adelaide, the 600 MW project will be located approximately 10 km off the coast from Kingston. The project will comprise between 40 and 75 (8-15 MW) offshore wind turbine generators. Subsea and overhead transmission lines will be used to feed electricity into South Australia's electricity grid. The proposed grid connection would either involve South Australian transmission system operator (TSO) ElectraNet's 275 kV Black Range substation in Willalooka or 275 kV South East substation in Mount Gambier.


As part of the EIA process, the project will also require approval under the Environment Protection and Biodiversity Conservation Act, 1999 (EPBC Act) for impacts to Matters of National Environmental Significance (MNES), including Threatened Ecological Communities, and Threatened and Migratory Species.


Subject to planning and environmental approval, the wind farm is expected to commence construction in 2024 or early-2025 and generate electricity in 2027.
