Protecting our energy security

Our electricity transmission and distribution system has served us well.

Location of Victoria’s energy sources and a rapidly changing mix will affect future operation of electricity grid. We are moving to more diverse and lower emission generation. That means modernising our grid to maintain efficiency and reliability.

The Victorian Government is supporting adoption and development of new technologies. These include large-scale battery storage and smart ‘micro grids’.

Each of these is important to:

  • enhanced energy reliability
  • address demand across the grid
  • avoid costly upgrades of fixed energy infrastructure

Did you know Did you know

The Victorian electricity grid delivers power throughout Victoria. It also carries power flows between Victoria, Tasmania, South Australia and New South Wales. This means the Victorian grid must integrate:

  • renewable energy from Tasmania’s hydro power generation
  • South Australia’s large capacity wind generation


Projects and reforms

The Victorian Infrastructure Plan includes 4 projects and reforms under this Energy priority. These are detailed in the Energy sector plan and full edition VIP, available for download together with:

  • Government response - outlines our position and addresses 137 recommendations made by Infrastructure Victoria in its 30-year Infrastructure Strategy
  • Technical report - indicates where projects and reforms meet the plan’s four objectives

Case study

Mini-grid trial in Mooroolbark

Victorian network operator AusNet Services is taking a Melbourne suburb completely ‘off grid’. Powering homes only with rooftop solar and battery storage. This is a first-of-its kind trial in Australia.

AusNet will install rooftop solar systems to 14 homes. Capacity will be between 3 and 4.5 kilowatts, with 10 kilowatt battery storage. This trial will demonstrate effectiveness of the mini-grid concept. An alternative to the century-old model of large centralised generators and expansive and costly networks.

The trial will test how well homes with residential solar systems and batteries can:

  • generate, store and share renewable electricity with each other
  • operate as a ‘mini grid’ via their local power lines

A control system will monitor and manage energy flows within the mini grid. This will enable energy stored in batteries to be shared between houses based on:

  • individual household needs
  • diversity of customer loads within the mini grid
  • the needs of the network


The Victorian Infrastructure Plan identifies 2 other priorities within the Energy sector. They are:

Ensuring efficiency and affordability

Targeting net zero emissions
