This leaves Australia in an energy hole. The Federal government’s national energy roadmap is based on a huge commitment to renewable energy generation, firmed by hydroelectricity and hydrogen. The largest hydro project, Snowy 2.0, is billions of dollars and years behind budget. There are concerns about whether it can be completed, given the operational difficulties. Electricity dispatch systems need to constantly balance demand and supply to remain stable. Without a firming agent or process, the government’s plan will not work.
