The Accelerated Step Change Initiative (ASCI) gave ARENA the flexibility to support exceptional, breakthrough projects that are not otherwise eligible under other ARENA programs. It was only open to projects that were truly exceptional and sit outside the eligibility criteria for other ARENA initiatives and programs. A project must require an ARENA contribution of $5 million or more, with the overall project cost expected to be more than $20 million. ASCI was open to Australian and international companies and research institutions. ASCI has been superceded by the Advancing Renewables Programme and is closed to new applications.
