Executive manager of delivery Craig Stallan said the project incorporates new technology which will enable greater sharing of cheap electricity between the states.
“Despite the challenges posed by the pandemic we are working safely to deliver this important upgrade which will provide reliable, cheap electricity to customers,” Stallan said.
“TransGrid will have greater control of power flows between the states once this project is completed at the end of the year.”
Three new capacitor banks will be energised at the Armidale Substation during August and an additional one will be energised next month – eventually there will be six capacitor banks on site.
Similar works will be conducted next month in Dumaresq and at Tamworth Substation in October and November. A total of nine capacitor banks are being added to all three sites across the QNI project, to provide additional reactive power on the grid and keep the network stable.
The upgrade has created 155 construction jobs for the region on the transmission lines and in substations at Armidale, Tamworth and Dumaresq.
The project has provided opportunities for local suppliers including crane operators, accommodation owners, fencing, tree services, hygiene, safety, electrical and concrete companies.
