Australia’s Future Grid Forum• Long-term orientation to 2050 to demonstrate
key policy and technology choices not constrained by near term electoral cycles
• Whole-of-system to provide credible projections and quantitative analytics especially of the role of networks
• Industry-led to enable bold and informed discussion that examines benefits and drawbacks of different outlooks

1.Further electricity price rises are expected, even without a carbon price
2.The electricity system may transition from centralised to decentralised structure
3.Optimising energy efficiency, distributed generation, energy storage and the use of cost competitive gas can maintain energy affordability

• Disconnecting from the grid as a residential consumer is projected to be economically viable from around 2030 to 2040 when independent power systems are expected to be able to match retail prices of between 35 c/kWh and 40 c/kWh as battery costs fall.
• Onsite generation is projected to reach between 19 per cent and 46 per cent of total generation by 2050, up from 8 per cent today
• Network utilisation might decrease as a result of disconnection, despite efforts in managing peak demand
