The ANAO could examine the Department of Climate Change, Energy, the Environment and Water’s (DCCEEW’s) delivery of the Capacity Investment Scheme (CIS). DCCEEW describes the CIS as an Australian Government ‘revenue underwriting scheme’ to accelerate investment in: renewable energy generation (generation), such as wind and solar; and clean dispatchable capacity (dispatchable), such as battery storage. DCCEEW states that the ‘scheme provides a long-term revenue safety net that decreases financial risk for investors’ and that ‘this ensures more renewable energy projects get built’. An expanded CIS is being rolled out from 2024 to 2027. Auctions for both generation and dispatchable capacity are planned to be held regularly from 2024 to 2027 and to support about $73 billion in investment in the electricity sector.
