As of October 2026, average residential electricity usage rates across Australia's National Electricity Market (NEM) states typically range between 30 and 35 cents per kilowatt-hour (c/kWh), though this varies significantly by state, retailer, and tariff structure. For instance, South Australia has some of the highest rates, with 2026-27 Default Market Offer (DMO) caps reaching 41.91 c/kWh for usage and a daily supply charge of A$1.80. In contrast, Tasmania's regulated Tariff 31 usage rate is around 27.95 c/kWh. Daily supply charges, which are fixed fees, can add an additional A$0.75 to A$1.85 per day, depending on your network and retailer.
The Australian Energy Market Operator (AEMO) released its 2026 Electricity Statement of Opportunities (ESOO) in August 2026, indicating a clear pathway to maintaining reliable electricity supply across the NEM over the coming decade, with no forecast reliability gaps identified before 2030. This improved outlook is supported by a record 9.1 GW of new generation and storage capacity connected in the 2025-26 financial year. AEMO's 2026 Integrated System Plan (ISP) reaffirms that a system built on renewable energy, firmed with storage, backed by gas, and connected through upgraded networks, is the least-cost pathway to secure and reliable electricity as coal plants retire.
Several critical transmission projects are advancing to strengthen the grid and integrate new renewable energy.

Marinus Link, a 345 km undersea and underground interconnector between Victoria and Tasmania, commenced construction in 2026 for its 750 MW Stage 1, aiming for completion by 2030. Additionally, the Environment Effects Statement for VNI West, a proposed 500 kV line connecting NSW and Victoria, is currently on public exhibition until November 2026, with a project approval decision anticipated in late 2026.
