Network Access Planning

Our Network Access Planning engineers assess, coordinate, and sanction the planned release of assets from the National Electricity Transmission System (NETS), for maintenance and commissioning of new connections and equipment.

We use AC and DC transmission system analysis tools to optimise efficient and economic access to the transmission system, and ensure that throughout all of the outage scenarios, the transmission system continues to operate safely within the Security and Quality of Supply Standards.

When all outage planning activities are completed, a fully operable outage plan is handed over to the Electricity Network Control Centre (ENCC) to deliver in real-time.
