Australian households and businesses would receive incentives to install batteries alongside their solar systems if the Greens have their way.
The minor party wants a national energy storage target of 20 gigawatts by 2030 - 10 times the planned capacity of the Turnbull government's Snowy-Hydro plan.
Its new policy, released on Wednesday, includes support for small- and large-scale systems, establishing standards for household and business batteries, and changes to electricity market rules to better incorporate the use of storage.
"We want to supercharge demand for batteries in households and business, saving people money and creating jobs with a program that mirrors the support for rooftop solar," Greens energy spokesman Adam Bandt said in a statement.
"Snowy 2.0 is a nice idea, but if the government was serious about energy storage it would put in place a target and incentives for storage right across the electricity network, not just in one place."
The small-scale scheme would operate similarly to the RET, with homes and businesses which install batteries able to generate certificates that electricity retailers would have to buy.
The Greens envisage the large-scale scheme would cost taxpayers $2.2 billion over four years for the energy market regulators to contract and build grid-level storage projects.
Storage is widely regarded as the final puzzle piece in the rapidly changing energy market, as it can be used to "back-up" renewable generation and switch on quickly when demand for electricity spikes.
Chief Scientist Alan Finkel has recommended the government require new renewable projects to incorporate storage to improve the energy system's reliability.
Prime Minister Malcolm Turnbull is evangelical about the expansion of the Snowy Hydro scheme to include extra pumped hydro storage, but it is unlikely to be completed before the mid-2020s and will cost about $2 billion to build plus about that much again to upgrade the transmission network.
A recent study found more than 22,000 sites across the country that could support off-river pumped hydro storage - with two dams at different heights connected by a pipe and turbine - and ANU researcher Andrew Blakers said selecting the best handful of these could provide enough storage to underpin 100 per cent renewable generation.
The Greens say their 20GW storage target could deliver 400-450 gigawatt hours of energy, which would also be enough to underpin entirely renewable generation in Australia.
