ARENA to use ACT-style auctions for 200MW of large-scale solar

The decision by ARENA will likely please the Federal Government, which despite wanting to close both ARENA and the Clean Energy Finance Corporation, wants both agencies to focus on large-scale solar – anything but wind farms – while they still exist.
The push for big solar, and the auction technique, follows the success of the ACT government auctions for both wind and solar, and its upcoming “next generation” solar tender, which will include storage.
Such auctions are widely used overseas, in South Africa, Europe, The Middle East and in the U.S., where it recently obtained prices at less than US4c/kWh, although these included tax breaks. As RenewEconomy reveals today, Windlab is proposing a massive 1,200 MW solar and wind park in north Queensland.
“Large-scale solar PV remains in its infancy in Australia with only three projects commissioned and a further two under construction,” the agency notes. “When the projects currently under construction are complete, installed capacity of large-scale PV will total 241 MW. This is well behind the installed capacity of comparable international markets.” Indeed, Australia ranks just 24 in the world in big solar.
As reported exclusively by RenewEconomy last week, ARENA is looking to bring down the cost of solar PV in Australia to around $110/MWh and $130/MWh in the medium term. This compares to $140/MWh and $170/MWh now, around three times the price of solar PV in the US, which has better and cheaper financing sources.
“ARENA has observed significant cost reductions in large-scale solar PV over the past few years and expects these to continue due to a combination of international and local improvements,” it says. “The cost trajectory of large-scale solar PV is expected to see the technology become competitive without additional support in the medium term.”
The decision was welcomed by The Greens, with climate and energy spokesperson Larissa Waters saying it was “a glimmer of hope in an otherwise bleak outlook” for renewable energy in Australia.
“Supporting investment in large-scale solar is exactly what ARENA has been set up to do,” she said. “The Greens structured the Clean Energy Package so that ARENA encourages emerging technology to become commercially viable, at which point the CEFC takes over to bring proven technologies to market.”
