ElectraNet has identified a preferred alignment for the future upgrade of the transmission line between Yadnarie and Ungarra, SA.
The new alignment which runs almost parallel to the existing transmission line, will aid in securing the Eyre Peninsula’s electricity transmission supply.
The identification of this southern section follows on from the commencement of easement option negotiations for the northern section between Cultana and Yadnarie last year.
Information was gathered through desk-top research, technical field studies, direct engagement with landowners and the Eyre Peninsula community, as well as extensive ground-truthing, and then evaluated.
The process also included a geo-spatial multi-criteria analysis, which assessed various alignment options to identify the route that best balances environmental, cultural, social, land use, engineering and cost criteria.
“ElectraNet had received a lot of constructive feedback throughout the process, and will now engage directly with landowners along this section of the line route to discuss options for acquiring a new easement,” said Mr Phil Court-Kowalski, ElectraNet’s Executive Manager Network Services.
“While the construction of the new transmission line is not taking place immediately, securing the future route and easement for the new line now ensures that eventual construction can proceed as soon as a load trigger occurs.
“This route has the least net environmental impact, recognises culturally sensitive sites, reflects community preference and also achieves the lowest long-run cost for consumers,” Mr Court-Kowalski added.
Further work is required to identify the preferred alignment for the southern section between Ungarra and Port Lincoln.
This involves exploring constraints, particularly around White Flats and Boston (behind Port Lincoln), where relatively new residential development has come much closer to the existing transmission line.
