AEMO gives SA-NSW interconnector project top priority
A $1.5 billion project to build a high capacity electricity interconnector linking South Australia and New South Wales has been listed as a top priority by interconnector the Australian Energy Market Operator. AEMO has published its Draft 2020 Integrated System Plan (ISP), listing the 330kv SA-NSW transmission line at the top of its Group 1 Priority Projects. The 900km interconnector linking Robertstown in South Australia’s Mid North with Wagga Wagga in central New South Wales is expected to provide grid stability and lower electricity prices in South Australia when completed from 2022. Electricity infrastructure provider ElectraNet is planning the $1.5 billion 800MW National Energy Grid interconnector with its NSW counterpart TransGrid. The project was listed as Group 2 in the previous 2018 Integrated Systems Plan. Other projects given Group 1 priority in the 2020 Draft ISP include upgrades to interconnections linking Queensland with NSW and NSW with Victoria and Increasing inertia and fault current in South Australian transmission networks. South Australian Minister for Energy and Mining Dan van Holst Pellekaan said the project would increase stability and reduce electricity prices for residential and commercial customers. “In essence AEMO has labelled the SA-NSW interconnector a ‘no brainer’ to deliver cheaper, more reliable electricity for South Australian households and businesses,” he said. “South Australia currently only has interconnection with Victoria which puts us at the end of the line and vulnerable to the type system risks that saw the entire state blacked out in 2016.” Modelling released earlier in the year showed that small and medium businesses with significant electricity consumption will save many thousands of dollars each year when the interconnector is energised. The South Australian Government granted the interconnector Major Project Status in June with the NSW Government is declaring it Critical State Significant Infrastructure in August.
