Strategic energy infrastructure investments under uncertainty Coordinated planning for Australia’s electricity and gas systems
- Australia’s transition to a net-zero economy will likely require gasfired generation (GFG) to back up renewables, especially in winter through late-2030s1 (Fig. A2).
- Southeast Australia experiences depleting gas fields, posing supply
risks for both gas and electricity systems (Fig. B2). - Potentially early coal plant retirements and delays in the
deployment of new energy infrastructure can drive higher gas
demand, exacerbating uncertainty and thus supply adequacy risks.
