Solar and wind provide 99% of new generating capacity in Australia, with renewables supplying over 40% of power to the main grid. Australia will need six times as much solar and wind to reach net zero through electrification. Building new transmission corridors is necessary, but existing lines are not sufficient. The grid operator plans to build 10,000 km of new transmission lines, with a focus on high-voltage direct current lines to unlock renewable resources. Optimizing new transmission corridors is crucial for Australia's future grid. A study has identified potential high-voltage direct current (HVDC) transmission line corridors in Australia to connect renewable resources in northern regions to population centers in the southeast. These corridors could significantly reduce wholesale electricity costs by 8-18%. Energy storage schemes like Snowy 2.0 could also help cover seasonal gaps locally. Community buy-in is crucial for such projects, and the benefits of unlocking renewables can be quantified for each local government area. Policymakers should prioritize building these transmission corridors to meet new demand and consider pairing them with pumped-hydro schemes. The article discusses the importance of energy storage in balancing variable renewable generation and maximizing the use of transmission lines. Cheng Cheng, a Senior Research Officer at the Australian National University, highlights the role of energy storage in the transition to a more sustainable energy system. This technology helps to ensure a reliable and stable energy supply while also reducing greenhouse gas emissions. Energy storage is a key component in achieving climate solutions and increasing the efficiency of renewable energy integration.
