ElectraNet will undertake essential maintenance on the transmission network on the southern Yorke Peninsula on 17 October, which will impact electricity supply in the region.
This maintenance will affect households and businesses in the Yorke Peninsula’s south including townships such as Coobowie, Edithburgh, Marion Bay, Port Giles, Stansbury, Yorketown, Warooka and surrounding areas, which are expected to be without power between 11:00pm on Saturday 17 October to 7:00am Sunday 18 October.
Essential maintenance is scheduled at the Dalrymple Substation to replace a faulty insulator. This will help reduce the risk of unplanned outages over summer, when dust and salt can build up on insulators and cause electricity arcs across insulators.
ElectraNet appreciates the inconvenience and impacts of power outages and thank those impacted for their continued patience.
