AUSTRALIA’S OFF-GRID CLEAN ENERGY MARKET RESEARCH PAPER This report was produced with support from the Australian Renewable Energy Agency (ARENA). ARENA was established by the Australian Government as an independent agency on 1 July 2012 to make renewable energy technologies more affordable and increase the amount of renewable energy used in Australia. ARENA invests in renewable energy projects, supports research and development activities, boosts job creation and industry development, and increases knowledge about renewable energy.
