![]() The modelling is being challenged, though. Modelling by the AEMC shows households with solar and a battery would be better off financially under this system. "So not only trying to disincentive solar when it's not needed but giving an incentive for customers to actually consume the solar-generated cell move it to times of the day when it's needed." "The other part of it is two-way pricing," the AEMC's Benn Barr said. Now the AEMC is even controversially proposing an overhaul of the system that could see solar exporters penalised for sending energy out during the day. In South Australia, energy authorities even recently used powers for the first time to prevent thousands of solar homes from sending power to the grid. For instance, in July Victoria will drop its minimum level. The Northern Territory example is extreme, but it shows in one fell swoop what effect both subsidies and tariff reductions can have on consumers.Īnd battery industry proponents believe more levers are about to be pulled. In a statement, the Territory's Minister for Renewables and Energy Eva Lawler said the NT had no plans to axe the grandfathering arrangements. Solar electrician Ben Hassall also told ABC News that most batteries he was installing were going into new solar systems. "You were using the grid to store the excess energy your solar was producing," Darwin solar technician Ben Hassall said. Its so-called "one for one" gave solar exporters like-for-like back from the grid. ![]() Until a year ago, the Territory had no battery subsidy schemes and it also had by far the most generous feed-in tariff in the nation. That works out to about 4.4 per cent of solar households. Overall, about 110,000 home solar batteries have been installed nationally, according to Sunwiz data. South Australia's generous battery subsidy scheme and uptake of solar overall has seen it become the biggest market for household batteries, followed by Victoria and NSW. Some energy providers are also trialling so-called virtual power stations that incentivise household batteries while subsiding them. ![]() Some states are now even offering consumers interest-free loans to buy household batteries. In his recent market analysis, Mr Johnston also noted "historical forecasts of a massive uptake were predicated upon a steep price drop in batteries but that hasn't played out thus far".īut there are growing subsidies across Australia. "You wouldn't say across the board that batteries are going to have a fantastic payback or represent a fantastic return on investment just yet for most households," Mr Johnston said. ![]()
